Canon announces development of the EOS R5 full-frame mirrorless camera

depends on your camera. Some cameras have DLO built into the JPEG processing so you can turn that on, and it should help your JPEG's. Otherwise, no, it needs the RAW data if you are doing it in post processing on your computer. The RF mount cameras do this much better. as the DLO data packet is stored in the lens itself and downloaded in the camera automagically. with other DSLR's .. i think you may have to load the lens profile manually into the camera.

See, I loaded a lens profile for the 85 1.8 into my RP (firmware 1.4.0) and noticed no difference in LOCA or PF with or without DLO turned on, when making in-camera JPGs, which led me to believe that it's only helpful when shooting RAW (but even then, I can just use the profiles in Lightroom CC).

From Canon USA Press Release:



Looks like the wait won't be long for a lot of details. At least we should know the type of cards and probably confirm the resolution. It will be interesting to see how fast and accurate the autofocus is. I hope it doesn't hunt and lose focus like the R. Otherwise that 500mm zoom won't be of much use to birders.

Maybe, maybe not. Remember when the RF 70-200mm f/2.8 l IS mockups were on display at trade shows inside a glass case? So people couldn't even tell if it was an extending design?

lack of mechanical mode dial and separate video switch are the only negatives so far

Not everyone views the lack of a mechanical mode dial as a negative. The 1-Series doesn't have them.

The red button on the top appears to be the "instant" video button just like on the EOS R.

I think a key thing will be how the Canon lens progresses in aperture. Apparently the Sony is f6.3 at everything after 300mm, so if Canon can maintain f5.6 at 400mm, then it could be a clear winner if aperture is the main gripe.
The optical factor that determines resolution is the diameter of the entrance pupil and it is the same for a 500mm f/7.1 as 400mm f/5.6. I wrote a lot on a similar topic of 500mm f/5.6 vs 600mm f/6.3 in https://www.canonrumors.com/forum/i...g-and-600mm-f-6-3-vs-500mm-f-5-6-zooms.38178/ A 500mm f/5.6 is significantly better than a 500mm f/7.1. I'd also be surprised, but pleased, if the new 100-500mm would open up to f/5.6 at 400mm. My take is that the 100-500mm will be a very nice safari lens for most people and a wise marketing decision by Canon. If I get an R5 or R6 I will most likely buy this lens. But, it's not what I wanted.
This announcement is most timely for me as I am evaluating the short to medium term solutions for what is best for my bird shooting, and I live in the short to medium term.

Could be cheaper... Sony front element is 95mm vs 70mm for the 100-500. If it is sharp @500mm (which it should be or at least sharper than 100-400 + 1.4x @ 500mm), this could be a great addition and should be designed for use with the RF 1.4x = 140-700mm! Perfect for birders on a budget and simply crop to taste! Is there a compelling case for APS-C now... except perhaps for price?

Price is always a compelling case for some.

That's a very wrong assumption.
None of the aforementioned cameras have full compatibility with the EF system, including the Dual-Pixel AF and Dual IS, which most setups do not have (Except in the m43 system, which is not FF and not as good in terms of AF).
There are other things such as colour science, or an ergonomic design without the bulk of a Panasonic S1.
It is simply a missing piece of an unfinished puzzle.
Yes, there are other cameras with great specs, but they aren't working as well as an integrated system. Nobody else will be able to match that because that's not how they've designed them in the first place.
There are now adapters for Canon EF to Nikon Z (the Fringer and Techart) that give full capability of most lenses and AF speed and accuracy as good as the Nikon ones, apart from our having to select either/or for IS and IBIS.

But they won't work together nearly as well as with Canon and their AF systems are also inferior to Sony or Canon especially in low light.
It is just not a seamless integration with adapters (which are much more expensive anyway, everything moves backwards as well, so why bother).
In short, it is a compromise.
And of course, we shouldn't forget that most RF zooms have the IS as well, unlike almost all of the Z lenses.
As I wrote, imho the Canon mirrorless system was designed in a more thoughtful way.

I don't mind a slow 17-35 f/5.6 lens to complement the 24-105. Also, some lightweight 28 f/1.8, 50 f/1.8 and 85 f/1.8 lenses will be greatly appreciated.

Primes are dead except in the premium space. Not enough folks seem to buy consumer grade primes any more. Everyone happy with cheap lenses wants "zoomz".
