With my focus on nature and bird photography, I have long preferred APS-C format cameras, due to the better “reach” (narrower field-of-view, with the same optics) that is important for photographing shy, far-away birds and animals particularly. Said that, several producers, Canon included, have put most of their research and development efforts into the full frame camera systems. I discussed the Canon EOS R System earlier in this blog (in February 2020), and while at that point I was committed with the EOS M line of APS-C cameras and lenses, I was also growing frustrated at the bad ergonomics and other limitations of EOS M cameras. However, there were also several downsides as well as possible long-term benefits in the more “professional” full frame EOS R System that left me hesitant at what to do in the long run. This summer, after rather lengthy consideration and research, I finally made the leap into the new, “full-frame era”. Or, more appropriately (as will explained below), I just decided to add one more tool into my toolkit.
When EOS R5 camera was introduced in summer 2020, much of the attention was focused on its amazing 8K video capabilities. However, as I am not a cinematographer, my interest was at the side of still image photography. The main “sales points” of R5 in this area include a 45 megapixel, full-frame sensor, up to 20 fps speed in continuous shooting (electronic shutter, and up to 12 fps mechanical), a built-in image stabiliser (up to 8 stops, with some selected modern lenses), and – perhaps most importantly for me – a really good autofocus system trained with machine-learning to pick up the shapes and even the eyes of animals and humans alike. There are additional benefits when moving from smaller, APS-C cameras, such as a really nice, deep grip to hold on (with M50 only two or three of my fingers, in addition to thumb, can touch the small body while carrying it), the full set of three rotary dials (enough for setting dedicated controls for both ISO, aperture and shutter speed, each with a dedicated physical control), longer-working batteries, better weatherproofing, dual card slots, less noise in low light, etc., etc. It is also worth noting that R5 uses the same processor (DIGIC X) as the more expensive, professional flagship DSLR camera EOS-1D X Mark II.
There are also significant downsides in a full-frame camera system, when compared to APS-C ones. The financial one is the most obvious: this is a much more expensive camera than any I have owned before. It is also worth noticing the camera body is just the first part of the investment, as the new, R system lenses are also generally expensive. They are robust, of high optical and physical quality, large and heavy. Going to a casual camera walk or run around a new city while on tourist mode, I will definitely rather prefer carrying the compact EOS M50 (387 g), coupled with e.g. the small and light EF-M 55-200 mm (260 g), rather than R5 (738 g) and RF 70-200 mm F2.8L IS (1070 g); there is also several thousands of euros/dollars price difference. Not to discuss the price and weight of any full-frame glass which reaches into the 400-600 mm area, which is where the true bird and wildlife photography generally tends to start. Thus, to sum up, I will not give up my EOS M camera and lenses anytime soon. There are uses and needs for both the large and the compact system. A serious R Series camera and lens setup is something that you would particularly take out when you are working for some particular, photographic goal or project. (This is why some people are actually paid to use these things. That is what “professional” means, after all.) The small system is good for those long walks.
In the actual bird photography, comparing ASP-C and R5/full-frame in the field, there are similarly plusses and minuses. The main strength (and one of the key reasons why I made this investment in the first place) of R5 is that the large, 45-megapixel sensor coupled with the image stabilisation and powerful AF system allows taking more, and more sharply focused images to start with. With very fast-moving objects like flying and bush-jumping birds, only a small fraction of photos is generally usable. A fast-shooting, fast-focusing camera-and-lens system makes a great difference in an actual wildlife photography situation. There is a “crop mode” in R5, which will narrow down the field of view into the same as the APS-C camera (applying Canon’s 1.6x crop factor, in-camera). But the full-frame image of R5, when cropped so that it would represent the same field of view as my old M50 APS-C camera is “only” 17.3 megapixels (my much cheaper M50 has 24.1 with that same field of view). However, the experience of shooting birds and wildlife with R5 is indeed better than M50: it is much easier to keep e.g. a flying falcon or swallow within the large image frame of R5, and the powerful AF system does a really good job in keeping the bird sharp in the image – as long as the photographer is capable of taking care of the targeting and composition at somewhat decent level.
In the 45-megapixel images there is room for cropping in many different ways. The optical quality does not magically change, of course, with the upgrade of camera body if one is still using same lenses as before; though, the reduction of noise and better low-light capabilities mean that it is possible to shoot birds with even pretty “slow” lenses (like my Sigma 150-600mm f/5-6.3 C DG OS HSM), while going rather high ISO sensitivity values, and still come up with frames that can be used, particularly if software tools like Topaz DeNoise AI and Sharpen AI are applied in the postproduction. The main benefits of this upgrade from a crop-camera to a full-frame one in the end come from multiple areas, mostly ones related to the art and craft of composing and creating images, while it needs to be emphasised that the baseline optical image quality remains at the domain of lenses used.
There is apparently an interesting learning curve that comes with the transition from Canon’s entry-level into a full-frame/professional cameras. After couple of weeks, my automated procedures and reactions are still largely coming from the APS-C world, and, for example, I even still occasionally try to find the power switch from the old location (at top right; in R5 the switch is at top left). There are no pre-programmed “easy” photography modes such as the sports, macro, or portrait modes in the EOS R5 (there is the fully automatic, “smart” A+ mode, however). The idea seems to be that a photographer who wants to use a “pro” camera must understand the underlying logic of photography technique enough, and be able to set up different aperture, exposure etc. priorities according to the subject matter, scene, and desired effects.
The full user’s manual for R5 is 921 pages, and I have the feeling I have only just scratched the surface of what this camera can do, and how it should be set up. But I have at least started personalising the main settings, such as customising three back buttons for quick access into my three key wildlife focusing modes: animal-eye autofocus, spot AF, and single-point AF. The logic here is that when I can see the animal/bird relatively clearly (or, e.g., when I try to photograph a flying bird), I use back-button AF technique first with the AF-ON button set for “Eye Detection AF”. Secondly my asterisk (AE lock) button is now set for spot AF mode, and the last (AF point selection) button for single-point AF. These two are normally used when the focused subject is half-hidden, hiding among branches as is often the case; after the initial AF lock, the system usually is able to follow by tracking, so the focus stays locked, when the target has initially been pointed and identified. For this initial selection, there is both a joystick and a large LCD touchscreen that can be used for moving the focus point around. Currently, I find myself using the touchscreen more.
There is more learning to be done, and I expect the possibilities opened up by the new system to challenge me for several years to come, in search for both better – or just more interesting – pictures and more improved photographic techniques and new ways of photographic thinking. However, my old cameras and lenses still remain in my toolkit, and they also have their times, places, and uses.
Have a happy photographic summer!
