Pros: Ergonomics, All-rounder, High ISO sealing, Gust

Cons: Card slots

Opinion: Taken used after the release of the R1, it is an all-rounder camera and I use it mainly for sports, weddings and various events. In principle, I also share all the previous comments, I am very satisfied with the purchase. For the type of machine, I would have preferred 2 CFexpress type B cards instead of 1+1 SD.

Pros: Sharpness, focus, viewfinder, dynamic range, high ISO noise hold. I add focus with the gaze, overbust of the shot with 195 shots in a second, synchronization with the phase of the Led lights absolutely spectacular.

Cons: Battery life: forget the endurance of the 1D M IV! but also of the 1DX M II or III!

Opinion: I modify the post: I finally managed to do three replicas of the same show, so I was able to seriously test the car: I varied the following parameters under the same conditions. 1) Focus tracking: unrivaled. What amazed me, I had never tried it, was "the chase with the gaze", that is, where you look focuses. IT WORKS GREAT! Except that contrary to what they recommend, I have seen that it works well only if you make only one setting, the more you do the more the machine gets "tangled". He is not 100% accurate but still does not miss a beat. Just be careful not to look at the parameters at the bottom because it obviously blurs everything ?. Moreover, my eye does not withstand the brightness of the mirrorless viewfinder for long, so I always shoot with the screen, I feel GREAT in it and I do not tire the eyes; but in some steps it can make a difference. 2) 1.6 magnification: I have always avoided it because it has always degraded the quality of the image. With the R3 the quality remains excellent! so in many situations it can be used without losing quality. 3) the overbust of 195 shots in a second: it makes a maximum of 50, then there is a buffer interval, but you have those 50 shots in a quarter of a second that really allow you to capture the right moment when the movement, as in dance, in its perfection is fundamental. Compared to the classic engine, it must be said that you still have to hit the moment of movement, but in that fraction of a second you have 50 different possibilities. not to be used all the time, you have to insert it and then disenseri, but it is an extra gear. 4) Finally the electronic shot: with LED lights it has always been a nightmare. It finds the phase of the light very well, automatically adjusts to it, and COMPLETELY solves the banding problem! I absolutely recommend the purchase, you save compared to the r1, which certainly gives more, but it is an absolutely exceptional machine. The definition, thanks to the thinner low-pass filter, is absolutely FANTASTIC, and also allows for large crops... Just be careful to calibrate the definition well with the photo styles, because at full definition some artifacts could also appear, you can't have ? everything!

Pros: Record high ISO file quality, general file quality, very beautiful color tending to be warm, top AF with all its modes, easy to manage raw file, dynamic range

Cons: Image view and distant zoom button

Opinion: A definitive camera that excels in all genres, ideal for set astrophotography and clearly for those who shoot in sports, weddings etc. The file at high ISO is really impressive 12,800 ISO has a really fine and contained grain, great dynamic range and color depth, beautiful and robust camera body, infinite battery, effective eye control, 24 megapixels of quality allow a modest crop, clearly no the extreme ones that allows the R5, a complete camera vote 10.

Pros: Excellent in everything or almost.

Cons: View button and trash too far to the bottom left, but these are just habits.

Opinion: Thanks to the lower prices after the release of the new R5 I was able to afford it. Spectacular AF lock and ISO tightness. The slight crops for on-the-fly framing in events do not ruin the quality of the jpeg and you forget that it is a 24 mpx. File very close in quality to the 1DXmk3 that I have used on loan many times. Together with the R5mk2 they play very well as hooking and bursting. For the rest, I agree in principle with all the previous comments. Nothing to add.

Pros: Speed of subject attaching, workability and quality of the file, ISO hold, ergonomics, battery life, simple and clear menu.

Cons: Mine is afraid of humidity, if it had a few more pixels it would be perfect.

Opinion: I use the R3 exclusively for birdlife and the performance is excellent. I come from a 1 DX Mark II, which is already excellent, but the subject tracking of the R3 is another thing. I used it with adapter and EF 100-400 without losing focus speed. Canon has done a great job of technical and marketing. Now I mount the RF 100-500. I unfortunately had a couple of problems during two days of rain (not intense). The first time, the dial on the back (which I use for apertures) no longer worked, and the second time, the screen turned off while rotating. Once dry (I repeat, just a few droplets) the camera was perfect again. The EOS R3, for me, is still exceptional.
