I like the best drone category. Is the best drone to be DJI drone or DJI drone? Or is it going to be DJI drone or perhaps DJI drone?

Sounds like homework for 3rd graders from the former USSR:

So it can take pictures but can it actually make and receive calls? I still wonder how should I rate Phone and Messages app when it ask me to do so... Let me think.... 5-stars when I can make calls and 1-star if not?

I suppose decent alternative for folks using Windoze PC and iPad tablet. Another solution that works natively without any dongle is Samsung tablet. Been using Galaxy Tab S7+ as secondary display with my laptop running Windoze for quite some time now.

Eugene A: "Moon" designation should be reserved for our planet Earth's natural satellite.

Just like the "Sun" which is reserved for the star which we are orbiting.

Perhaps the difference is between a "moon" and the "Moon"?

IamJF: "Remeber, this lens can not autofocus in the corner"
Cheap but useless ... no thanks.

I'm well aware of that. That's being said, crop mode doesn't have to be for the EF-S lenses only. I'm sometimes shooting distant objects in crop mode (especially when I know I would have to crop from full-frame image) because subject is bigger in the viewfinder in x1.6 mode and AF covers almost whole cropped area (case of RF600 and 800 lenses). I know I'm getting only a fraction of the sensor resolution, but this helps me tracking and keeping subject in the AF area.

Here's 600 and 800 AF coverage:

And one can always switch to crop mode to get it even wider.

Anastigmat: To me, mirroress cameras are digital equivalent of rangefinder cameras. They offer quieter operation by getting rid of the mirror. I can see White House photographers using them instead of Leica M series cameras or digital SLRs. They enable the design of wide angle lenses with rear elements protruding into the camera body to improve sharpness. They are more compact if you use mainly wide angle to short zoom lenses, but they offer no reduction in size when using super telephotos. That is because the length that is removed from the camera body has to put back into the telephoto lens.

Mirrorless cameras are not going to replace DSLR cameras. Both formats have their own advantages and disadvantages. They will continue to coexist well into the next few decades.

Honestly, I've sold 5d3 (kept bunch of EFs) and bought kit R6 with RF 24-105 f4 and 800 f11. After shooting with R6 for last 6 months I'm not looking back to SLR. Still have 7d2 and keeping it only as a relic as it is not worth much those days.

Kenneth Almquist: The video notes that the EOS R5 autofocus system is only partially functional when used with an f/11 lens (only focus points near the center work), but doesn't say what happens with other camera models.

One would think that Canon would document the compatibility of their cameras with f/11 lenses, but apparently not. I checked the R5 specification on the canon web site. It didn't say anything to indicate that the not all of the focus points are usable when you have an f/11 lens. I skimmed the manual and didn't spot any mention of the issue there, either. So I looked at the specifications for the lens to see if it had any notes about camera compatibility. It didn't.

Since a major appeal of this lens is price, I doubt that many users are going to be pairing it with an R5. The lack of information about compatibility with other Canon models seems like a big omission.

I have the RF 800mm which I use frequently with EOS R6. Like the RF 600, only the center part of the image works with AF. It is not a small area, but it makes sometimes tricky to track birds in flight. Switching R6 to crop mode (x1.6) results in about 85-90% AF coverage (only in the extreme left and right sides of the image camera won't do AF). I've managed to take with this combo a lot of tack sharp photos of wildlife (including bald eagles and ospreys diving and catching fish from the water on a sunny day at F11, 1/2000 sec, 3200-6400 ISO). Even pushing the camera to 12,000 ISO produces IMHO good quality images.
I don't know AF area size for RF 600/800 lenses when mounted on R/RP cameras.

jwilliams: I'd like to own one, but at that price, my 16-35 4L IS will live on an adapter forever. It would cost me 1K plus my current lens just to essentially get rid of the adapter and save a few ounces. The EF lens has very good IQ and actually has reasonable distortion characteristics. I don't think the RF version will buy me anything in IQ. The prices on these f4 zooms are rediculous.

I've came to the same conclusion when I saw the retail price.

On article There can be only one: why isn't the EOS R3 an EOS R1? (582 comments in total)

There's always room for improvement. Perhaps R1 will be released without the mechanical shutter (only global electronic) , shorter viewfinder blackout than 1DX3 and flash sync all the way to 1/8000s. One can always dream :-)

This is what I was referring to (M$ = Microsoft).

1Dx4me: Yawn.....wake me up when canon announces the sensor resolution and price!!!!!!

I'd say R3 will cost $6000-$6500, so R1 when they announce it, can be marked up to say $8000-$8500.

Interesting that Sony din't decide to have built in vertical grip like Canon or Nikon pro DSLRs. One would think it would be easier do dissipate heat as well as adding larger battery. Nice to see that with a1 and EOS R5 we start seeing cameras suitable to any kind of photography.

In reply to:

HowaboutRAW: The Canon R6 and Leica SL2-S are better ILCs than the R5, unless you wish to print massive posters from the files.

The Leica SL 50mm f/2.0 remains the best lens of the year 2020, no matter what some voting, which didn't even allow for the SL 50mm's existence, claims. No, this Leica lens did not release until 2020 even though Leica announced it in 2019.

And the most interesting camera of the year, though for a limited market: The Leica Q2 Monochrome. Then the second most interesting, but entirely ignored in 2020 by DPR, so unlike the Q2 Monochrome, is the Leica S3--yes the S3 is out.

(The Sony A9II is a 2019 camera, and the 1DX III and D6 are basic line extensions, albeit the Canon does have the new 20MP sensor, also in the R6, even if Canon is still playing catch up to Nikon.)

Not quite. I have R6 and wish I bought R5 instead. When RF 600 or 800 lens is mounted on those cameras it offers limited AF area (due to the shallow aperture). Switching camera to crop mode widens the AF area but offers less pixels due to the crop factor. It translates roughly to 7-mpix on R5 and 17-mpix on R5.

I wonder if we will see EOS R with cropped sensor sometimes soon...

Can't they unify viewfinder layout? Why no vertical needles for exposure meter and flash compensation? It still drives me nuts that meter needle is in different place when shooting with two cameras (5D3 and 7D2).

Vcize: Sounds like a great camera but two things that sound really worrisome/annoying to me.

No articulating screen, really? I know we hear that a lot of times but this camera seems built for it. Holding the camera down low and touching my son's face on the LCD screen to enable AF tracking on his face just sounds like the perfect way to shoot a toddler. Same thing for overhead stuff like at concerts. Yet no articulating screen means no go on that. What the heck were they thinking?

Secondly, did I read this part right. There's no way to access/view exposure compensation while using Auto ISO without removing your eye from the viewfinder (and diving into a menu)? Isn't auto ISO like the most common usage for exposure compensation? How the heck did that get approved past testing?

Exposure compensation in M mode with Auto ISO - exactly what I was bitching about since 7DMkII. Forget about using top illuminated LCD when camera on the tripod shooting nightscapes. Surprisingly didn't see many users joining me in mourning. Guess the ansew is to shoot in full manual.
