Overview of the Canon EOS R7 in Ikelite Housing

DPG wish to thank Ikelite for supplying the Ikelite 200DLM housing for the Canon EOS R7 in addition to a pair of Ikelite DS230 strobes and numerous equipment used on this assessment. DPG would additionally wish to thank Pura Vida Divers to be used of their dive operation.

 

It’s been very practically 5 years since Canon launched its first full-frame mirrorless digital camera—the EOS R—and changed the venerable EF lens mount with the RF mount. We’ve seen a slew of cameras with “R” within the mannequin identify since—RP, R5, R6, R3, and so forth—but it surely’s been all about full body. Certainly, with the dominance of Sony, Panasonic and Olympus/OM System within the cropped-sensor market, we’d forgive you if you happen to’d imagined Canon had deserted the thought of manufacturing a mirrorless digital camera with a smaller sensor altogether. Fortunately, this was not the case: In Could 2022, Canon lastly unveiled its first mirrorless cameras with APS-C sensors—the entry-level R10 and the “fanatic” R7.

Whereas attempting to fathom a digital camera firm’s mannequin naming conventions is a idiot’s errand, to anybody coming from a Canon DSLR—myself included—it was apparent that the R7 was very a lot the meant successor to the broadly admired 7D sequence of cropped-sensor DLSRs. Having owned the 7D and shot the 7D Mark II extensively again within the day, I used to be eager to know if—after nearly eight years of growth in digital camera tech—the R7 would certainly show to be a worthy inheritor to the Canon APS-C throne.

Over the previous few months—for much longer than anticipated because of irritating climate circumstances and a few premature well being points—I used to be fortunate sufficient to have the chance to check out the R7 in Ikelite’s compact housing (together with a pair of Ikelite’s flagship DS230 strobes) in my yard testing grounds in Florida, on the Blue Heron Bridge and whereas shark diving in Jupiter.

 

A inexperienced turtle winging over a shallow reef: The Canon EOS R7 in Ikelite’s housing with a pair of highly effective Ikelite DS230 strobes made for a formidable rig (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, f/13, 1/50s, ISO 100)

The attractive eye and sample of an invasive pink lionfish: “Canon colours” is an actual factor, and the R7 is not any exception. The colours proper out of the digital camera are phenomenal (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, twin Ikelite DS230, f/4, 1/250s, ISO 100)

1. High-Spec’d Digicam, Extremely-Compact Housing

In fact, sensor dimension apart, the R7 shares little greater than a religious connection to the 7D Mark II. The R7 packs half as many pixels once more into the APS-C sensor (32.5MP vs 20MP), shoots half as many pictures once more in burst mode (15fps vs 10fps), and whereas each cameras make use of Canon’s tried-and-true Twin Pixel AF, the R7 has 10 occasions as many autofocus factors because the 7D Mark II (651 vs 65). The truth that the R7 has a single processor versus two within the 7D Mark II additionally goes to indicate simply how a lot know-how has progressed in what is almost a decade. One thing that hasn’t taken an enormous leap ahead is the RAW buffer: The 7D Mark II’s buffer depth was 31 frames, however the R7’s buffer isn’t way more spectacular, filling up after a simply 51 photographs.

For Canon DSLR customers, the change to mirrorless can be jarring at first. The R7 is considerably extra light-weight than the 7D Mark II (22oz vs 32oz) and dramatically much less cumbersome, and since the R7 matches very snugly within the Ikelite housing, this interprets to a particularly compact and travel-friendly rig. Apparently, that is tempered a bit of for macro images, because the RF 100mm f/2.8L loaned for this assessment is barely longer (5.8″ vs 4.8″) and heavier (26oz vs 22oz) than its DSLR counterpart, the EF 100mm f/2.8L. Nevertheless, one ought to understand that the RF lens gives a most magnification of 1.4x in comparison with 1x for the EF lens.

I’ll say proper from the beginning: The RF 100mm f/2.8L is my favourite macro lens ever. I’ve used it earlier than each topside and underwater, and each time I shoot it, part of me is tempted to develop into a Canon shooter simply for this lens—it’s that good! It focuses rapidly, it’s ridiculously sharp, even huge open, and it resolves a ton of element. On the R7, the 100mm is the equal of a 160mm macro on a full-frame digital camera, giving an exceptional working distance, which makes it a lot simpler to get photographs of skittish critters.

 

Atlantic longarm octopus: Even at wider apertures, the RF 100mm is extremely sharp and provides nice separation from ugly or distracting backgrounds (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, twin Ikelite DS230, f/4, 1/250s, ISO 100)

 

In fact, wide-angle photographers taking pictures cropped-sensor DSLRs at all times had an ace up their sleeves—the Tokina 10–17mm fisheye lens. For a lot of, this small and cheap lens, whereas not being optically the world’s most spectacular glass, stays the go-to lens for taking pictures the ocean’s largest topics, in addition to being nice for close-focus wide-angle work. Thankfully, whereas this versatile lens isn’t (but) accessible for RF mount, it capabilities effectively on R our bodies with the EF-RF adapter and I didn’t discover any points as regards to autofocus accuracy or pace. It’s price noting that you just even have the choice of adapting the Canon EF 8–15mm f/4L fisheye, which is optically superior however not fairly as huge at its widest.

 

Lemon shark at nighttime: With the EF-RF adapter, the much-loved Tokina 10–17mm fisheye lens performs in addition to, if not higher than, on Canon DSLRs (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, f/14, 1/250s, ISO 100)

 

The Ikelite housing for the R7 was the primary housing from the U.S. firm that I’ve utilized in most likely 15 years. The Dry Lock (Micro) port system is much superior to their previous four-screw port mount, and regardless of the housing’s plastic building, it feels sturdy and sturdy. There’s additionally one thing reassuring about having the ability to see—with your individual eyes—your digital camera protected and dry by the clear again. The housing comes with a vacuum valve, so all it is advisable buy is a vacuum pump if you happen to don’t already personal one. (There is no such thing as a digital detection circuitry included; it’s a case of drawing a vacuum and checking to see that the vacuum has held after ready for a time period.)

Ikelite gives a spread of strobe fashions aimed toward shooters of various ranges, with their present flagship being the DS230, a pair of which have been loaned for this assessment. Central to Ikelite’s “flash philosophy” is electrical triggering, so all Ikelite housings come as normal with a single electrical bulkhead and a guide strobe scorching shoe. Thus, “out of the field” you’ll be able to hook up your Ikelite DS-series strobe(s) and set off it/them in guide mode. For automated strobe publicity, all it is advisable do is add the suitable Ikelite TTL converter (linked between housing and sync cables) for on-the-fly switching between guide and TTL. When you have a number of extra O-rings to take care of, there’s little doubt {that electrical} triggering makes for a really sturdy and dependable connection.

Whether or not you need the added advantages that include a TTL converter is a private selection, however one housing accent that I take into account to be very important is a (ideally 45-degree) exterior viewfinder, which offers a full, clear picture of the digital camera’s EVF (whereas creating area on your regulator). As an exterior viewfinder wasn’t equipped with the housing, I solely used the digital camera’s rear LCD, but it surely made for a wonderfully pleasant taking pictures expertise all the identical. Given its high-quality optical parts, an exterior viewfinder is a considerable funding, and it’s debatable whether or not the R7’s mediocre 2.36M-dot viewfinder justifies it.

 

Scaly tailed mantis: The LCD on the R7 is brilliant and simple to see, which makes straight down taking pictures a lot simpler (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, Ikelite DS230, Backscatter Mini Flash 2 and Backscatter Optical Snoot 1, f/11, 1/250s, ISO 100)

 

I will finish this part on a constructive be aware about battery life—uncommon for mirrorless. The R7 comes with the LP-E6NH battery, which is identical one used within the full-frame R5 and R6 Mark II, and is rated at 770 pictures with the LCD and 500 pictures with the EVF. I discovered the R7’s battery life a pleasing shock. Whereas I didn’t have any wildly lengthy days taking pictures with it, I by no means as soon as discovered myself enthusiastic about battery life. For my fashion of taking pictures, I simply did a number of hundred photos over the course of a number of days and had no trigger to fret. Taking pictures video or spending eight hours out on the ocean taking pictures all the time are situations after I’d suggest bringing a second battery, however for a standard two- or three-dive day, I feel the R7 battery fares very effectively.

 

Even after a productive dive and photographing sharks all morning, I nonetheless had loads of battery life left to {photograph} this wacky hybrid batfish on the finish of my night dive (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, Ikelite DS230, Backscatter Mini Flash 2 and Backscatter Optical Snoot 1, f/13, 1/250s, ISO 100)

2. Massive, Daring and Lovely Pictures

The primary headline-grabbing spec of the Canon EOS R7 is its newly developed high-resolution sensor. There are few cropped-sensor cameras that pack in as many as 32.5 megapixels, and the R7 was certainly able to resolving tons and many element—a minimum of at low ISO settings.

In lower-light conditions, when it is advisable enhance ISO, a better pixel depend can come at a value—noise—and I did discover that noticeable noise crept into the R7’s RAW information pretty rapidly when growing sensitivity. There’s a touch of noise at ISO 400, and it’s fairly noticeable within the RAW information whenever you attain ISO 1600. By comparability, out-of-camera JPEGs—with noise discount utilized—are very clear. Thankfully, it’s an easy matter to scale back the high quality noise within the RAW information throughout post-processing and output superb-looking photographs.

 

Longlure frogfish perched on a sponge in ambush: The R7, particularly when paired with RF glass, produced lovely photographs, loaded with element, and razor sharp (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, 1x Ikelite DS230,1x Backscatter MF-2, 1x Backscatter OS-1, f/3.2, 1/250s, ISO 100)

 

A bane of Canon cameras previously was dynamic vary—how a lot element is preserved within the shadow and spotlight areas of a picture. Not so with the R7: I discovered that I might deliver out a number of particulars within the shadows and highlights when processing the RAW information. Dynamic vary was much better than older Canon cameras, particularly their DSLRs, with the attainable exception of the 1D X Mark III. In fact, you’ll not have as a lot latitude in post-processing as you do with a higher-end full-frame sensor, however you do have a great deal of leeway in case publicity is a bit off or it is advisable get well a part of a picture. When paired with the RF lens particularly, the element and sharpness of the photographs was extraordinarily spectacular.

 

I used to be pleasantly shocked by the dynamic vary of the R7. Not not like the full-frame R5, which I’ve additionally used, it was vastly superior to each different Canon digital camera I’ve shot (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, f/9, 1/80s, ISO 250)

3. Fast and Assured Autofocus Efficiency (Finally)

The 7D sequence was marketed as a line of cropped-sensor cameras able to taking up quick motion, as that they had nice autofocus and will shoot bursts at excessive body charges. The R7 may be very a lot in the identical mould, however makes large strides in each areas, a minimum of on paper. Canon claims the R7 inherits the top-of-the-line autofocus system from the flagship R3. I haven’t used the R3, so I can’t evaluate it, however I did have considerably blended emotions in regards to the general autofocus efficiency of the R7. In some cases, it was very, superb, and also you nearly don’t must do something in any respect. In different modes, it may be a bit unpredictable.

Canon’s two most important autofocus modes are known as “One Shot” and “AI Servo,” and there are any variety of completely different configurations in every mode. For macro, my favourite was One Shot, Expanded Spot Focus, and Topic Detection enabled. With macro topics, the R7 was uncanny in its capacity to search out what it was within the body I needed it to give attention to and would accomplish that practically flawlessly. Seemingly a difficulty with all mirrorless cameras, if you happen to lose give attention to a topic whereas utilizing an extended focal size lens, it may be problematic to have the digital camera relocate the topic once more. I had this expertise with the R7, and there have been a number of cases when the digital camera simply refused to lock on to what I needed it to give attention to. It was extra of a nuisance than something, however I might see it inflicting photographers to overlook a crucial shot.

 

Banded jawfish: The autofocus efficiency of the R7 is among the many greatest I’ve ever used—as soon as I discovered find out how to correctly set it up! (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, twin Ikelite DS230, f/10, 1/125s, ISO 100)

 

This Pederson cleaner shrimp was perched on a coconut, beneath a rock in very darkish circumstances, however the R7 with the RF 100mm macro had no points locking onto the topic (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, twin Ikelite DS230, f/11, 1/250s, ISO 100)

 

For huge angle, I usually desire to shoot in monitoring or steady AF modes. Broad angle on the R7 is after I encountered some attention-grabbing points. Relying in your AF configuration, I discovered the R7 persistently back-focused irrespective of the place it confirmed the precise focus level to be. This was extremely aggravating, particularly because the monitoring and steady AF have been billed as being taken from the top-level R3. Finally, nevertheless, I used to be capable of finding a configutation that did work very effectively: AI Servo mode, Topic Monitoring enabled, and Develop AF Space chosen. This ultimate setting was the important thing: When utilizing Entire Space AF or any of the Versatile Zone AF modes, the digital camera back-focused 9 occasions out of 10. Develop AF Space solved that downside, and the aforementioned settings turned my go-to for motion or transferring topics. With these settings, the R7’s wide-angle autofocus efficiency was wonderful.

 

Silky shark with battle scars: The R7 tracked this silky from 15 to twenty ft away, all the way in which till it was all however touching my dome port. Not as soon as did it lose focus (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, f/13, 1/13s, ISO 100)

4. A Good Instrument for Quick-Transferring Topics

For its time, the 7D Mark II and its 10fps burst taking pictures outlined it as the Canon cropped-sensor digital camera for quick motion. The R7 can comfortably declare that mantle within the mirrorless realm: It shoots 15fps with its mechanical shutter and even as much as 30fps with its digital shutter. With the right AF settings, the R7’s autofocus system was spectacular sufficient to maintain up with the best body charges, completely monitoring transferring topics—even these coming in the direction of the digital camera.

For me, and I think, for most individuals, 15fps with the mechanical shutter is loads quick sufficient. Taking pictures full pace with the mechanical shutter, I discovered myself with manner too many photos to undergo! For huge angle, I often shot not more than about 5–6fps. For macro, I desire to shoot a single body at a time, no matter digital camera. As already talked about, the R7’s buffer is barely 51 photographs when taking pictures RAW, so bear in mind that if you happen to’re utilizing larger body charges, the buffer will fill in only a few seconds earlier than efficiency slows.

 

This check shark burst at 10fps was typical of the spectacular hit price I achieved with the R7: The main focus of each body was tack sharp (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, f/10, 1/200s, ISO 100)

5. Dependable and Versatile Strobe Management

The R7 doesn’t characteristic a pop-up flash, so triggering is through the recent shoe on the highest of the digital camera. With the Ikelite system, it’s a easy matter of constructing the reference to the guide scorching shoe equipped with the housing or with the TTL scorching shoe that comes with the optionally available Ikelite Canon TTL converter chances are you’ll want to set up if you would like the choice of automated strobe publicity. Testing each guide and TTL flash choices, I discovered the Ikelite system labored completely: I had no points with reliability nor any kind of communication points between digital camera and strobes. Ikelite’s TTL implementation is among the many greatest accessible and works effectively for all kinds of topics, and whereas I personally desire to regulate strobe energy manually, I might absolutely recognize the attraction of TTL.

One approach that I personally love is movement blur images, the place a sluggish shutter pace creates the impression of motion whereas strobes are used to freeze the motion. By default, cameras are usually set to set off the flash when the primary, or entrance, shutter curtain opens at first of the publicity, creating unnatural motion-blur photographs the place the motion is in entrance of the topic. To get the movement blur behind the topic, it’s important to fireplace the flash on the finish of the publicity, when the second, or rear, curtain closes. It’s one of many first settings I modify earlier than I begin utilizing a brand new digital camera.

 

A sluggish shutter added some drama to this shot of a barbfish, which tolerated me placing the dome port proper in its face (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, Kraken Sports activities Hydra 2500 V2, f/11, 1/4s, ISO 100)

 

Sadly, with Canon cameras, you’ll be able to’t merely join any flash and allow rear curtain sync in digital camera; you’re required to make use of a Canon-compatible flash with a view to have the rear curtain sync choice accessible. Thus, with the guide scorching shoe that comes with the Ikelite housing, you’ll solely have the choice of first curtain sync. Nevertheless, you may get round this limitation by utilizing Ikelite’s TTL converter, which communicates with the digital camera like a Canon flash. The converter handles shutter sync routinely: At shutter speeds of 1/30s and better, first curtain sync is enabled, whereas at slower shutter speeds, sync switches to the rear curtain. (It’s vital to notice that the converter takes care of flash sync whether or not you’re taking pictures in TTL mode or guide mode—if you happen to love movement blur images, the TTL converter is a obligatory buy.)

As a aspect be aware, whereas the R7’s flash sync pace maxes out at 1/250s with the mechanical shutter (1/320s with the digital entrance curtain shutter), apparently, I discovered that I used to be in a position to shoot at 1/400s with the Ikelite DS230s. Nevertheless, whereas the digital camera registered 1/400s because the shutter pace, the EXIF knowledge recorded 1/250s. So both the EXIF is appropriate and the digital camera is misreporting, or the EXIF is wrong and the R7 can really sync sooner than the specs recommend.

 

Movement blur added life to this lemon shark portrait (Canon EOS R7, Tokina 10–17mm f/3.5–4.5 fisheye lens, Ikelite housing, Ikelite 6-inch dome port, twin Ikelite DS230, f/14, 1/15s, ISO 100)

6. Last Ideas

For sure, the Canon EOS R7 is a really spectacular high-end APS-C mirrorless digital camera, a logical improve for shooters coming from the 7D sequence of DSLRs or anyone transferring up from point-and-shoot and even Micro 4 Thirds. The R7 packs numerous efficiency right into a small-form-factor mirrorless physique at a really aggressive value, whereas Ikelite’s equally compact housing gives an amazing platform to construct a succesful and versatile underwater rig. Add an exterior viewfinder, a pair of Ikelite’s wonderful strobes, and a TTL converter, and you’ve got a full-fledged system that may serve you effectively for a few years.

If you happen to’re a severe shooter transferring into the Canon APS-C ecosystem, it’s price emphasizing the standard of the glass you’ll have accessible to you: on the macro finish, the excellent RF 100mm f/2.8L, and on the huge finish, the EF 8–15mm f/4L, which fills the body all through the zoom vary on APS-C cameras. And once more, let’s acknowledge the unimaginable longevity of the Tokina 10–17mm, the eminently inexpensive wide-angle choice which can not maintain any optics information however can nonetheless maintain its personal in spite of everything these years.

Maybe an important take-home message right here is that APS-C will not be useless in spite of everything. Removed from it. The Canon EOS R7 reminds us simply how cool it’s to be cropped!

 

Even with out the Eye AF engaged, the R7 appeared to know precisely the place I needed to focus and locked proper on to the eyes of this stareye hermit (Canon EOS R7, Canon RF 100mm f/2.8L macro lens, Ikelite housing, twin Ikelite DS230, f/10, 1/250, ISO 100)
