Canon EOS R7 pre-sales discussion, hypothesizing, and prognosticating

What do you lose shooting with CRAW versus RAW? I've read that there's some additional noise in underexposed areas but is it significant? Are there compression artifacts or other effects to be concerned with? Have the R5/R6 users here used it? Thanks!

I've asked craw users in other forums and I don't think I have seen anyone who can tell the difference, including latitude in processing afterwards. Everyone seems to quote a brief note from Canon about possible more noise in shadow areas.

I am likely to use it on the R7 to get more images through as a 40% saving of file space.

The 90D has less noise than the R5 in crop mode, if you view both at the same image scale, so unless the noise of the R7 is a bit higher than the noise of the 90D, the R7 should have less noise than the R5 in crop mode, and has almost double the pixel count, too. As far as your two 500mm lenses are concerned, that's down to apertures and aberrations. A 500/4 is obviously going to give les noise and more analog sharpness at an f/4 that the RF100-500 doesn't have (f/7.1). Lens first for the underlying analog image; focal length divided by pixel spacing for the number of pixels across the subject.

Ranked from best to worst, you should expect something like this:

Pixel resolution: R7, 7D2, R5crop, with the 7D2 much closer to the R5crop than the R7

Noise: R7, R5crop, 7D2, with the R5crop in about the middle, maybe a little closer to the R7.

All assuming that the R7 images exactly like the 90D. If there is less noise in the R7 than the 90D, then the R7 will have the cleanest APS-C sensor area of any Canon APS-C or FF camera, as the 90D is already about the same as the R6 in crop mode.

Thanks for posting John. Much appreciated

I'll take that R7 off your hands for $1600 plus the tax you paid on the $1499. That would put it in my hands for the the rearing of fledglings in the next few weeks.

I am trying to work out how well Canon and third party EF lenses AF will work with this camera, particular my Tamron 150-600, any ideas?

Better than on the DSLRs they were made for . My Sigma 24-105 worked perfectly fine on my RP with the EF-RF adapter, I'm sure it will be the same here.

Using what recent bodies?

7DII and R6. With 7DII about 50% that’s when I started using Auto ISO than full time on R6.

I push processing pretty hard sometimes lol so it will be interesting to eventually compare...

Not many agree with me but I suspect canon is holding onto plans to make a flagship APSC body depending on the success of these two new models. There is quite a bit left on the table for that to happen, like an upgraded EVF, BSI 30Mpx sensor, larger buffer, integrated grip etc. I guess I might be able eat these words 5 years from now or say I told you so in three.

That could be 3 to 4 years from now including shipping date, by then I already enjoyed the r7 and it’s time to upgrade again. .

These are for sure minor complaints for the new R8 (I'm calling it that for now as it doesn't deserve the 7 title) but I had a 7D2 and it was great. If it were up to me the R7 would be around the size of the R, would have built in GPS and would have kept the handy built in flash (I would have added both built in wireless control functions too).

The 7D2 was larger than ALL of the R models (until the R3 came out). Now here comes the R"7" (R8 as I call it), it's supposed mirroless successor, yet it's kid sized. Gone is the built in GPS. Gone is the built in flash. It can take all of the R glass which is great but now with a decent piece of R glass mounted it'll look like a goofy endcap hanging off the lens instead of a real camera. I imagine the camera mounted on a tripod and if you weren't paying attention and threw on a telephoto zoom without thinking, you'd rip the front of the camera off the rest of the body! Good thing the R glass is a little lighter!

If you call it r8, I call it R11. .

It sounds like something my friends with Olympus' brag about.

They can prefocus on a perch and when the bird comes in they take the shot. The camera records the previous frames so if they were slow to release the shutter they still get the shot.

Cool. I like this feature.

Yes, but I see an interesting corelation to the original 7D release. Nice body but we had to wait a couple yrs for the robust 7D2 and I feel the R7mkII will be a real winner as I gaze into my crystal ball...

Be interesting to see if Canon does anything with R4, R8, and R9...

I think it’s rather funny that he complains it looks like a camera for a kid yet complains that it misses a pop-up flash.

That’s true. I prefer the pro look than having a pop up flash . Even how small the camera is.
