    Industry News: The Sony Alpha a7c leaks ahead of the official announcement

    Well, there is a rumored 24-70 f/4, but no telling how small it will be. I think that if I were Canon, and I were going to make a very small body like this, I’d opt for the R sensor, have a detachable eyepiece like the M6 II, and maybe have a kit lens similar to what you mentioned. Collapsible...

    Industry News: The Sony Alpha a7c leaks ahead of the official announcement

    Looks like a full-frame competitor to the M-series. I saw on another site, 4K/30 for maximum video. I wonder if it's full sensor or cropped... Edit: Let me add, a detachable viewfinder like the M6 II would be preferable, would make it a sturdier body. I can visualize that corner-mounted...

    Interview: Canon addresses overheating concerns, workarounds and the Cripple Hammer

    This camera is state of the art - it does as much as can be done given the size limitations, weather sealing, and the state of progress in chip/sensor design. Next generation electronics will be more efficient, will be able to perform with less heat, will operate more energy-efficiently, but...

    Is the ultimate astro lens coming? Another RF 14-21mm f/1.4L USM mention [CR2]

    How about f/1.4 and low coma characteristics?

    Teardown: Canon EOS R5 by Lensrentals.com

    I just read it - if nothing else, that body is packed with electronics.

    Select Canon cameras can now auto-backup to Google Photos

    I wouldn't trust google to hold my beer while I did something stupid. They have an agenda, and if you don't agree with their agenda, they essentially cancel you.

    Is Scotch tape the answer to your Canon EOS R5 overheating issues?

    I was thinking the same thing - if you do this and it overheats, Canon won't cover it. Now, the algorithm that Canon uses regarding heat in the camera may be overly cautious, and may be subject to some firmware tweaking, but the overheat warning and prevention scheme is there for a reason.

    Gerald Undone completes exhaustive record time testing on the Canon EOS R5 and Canon EOS R6

    Is it the sensor that heats up, or a processor that is doing it? The sensor, since it has movement to deal with IBIS, would be difficult to cool other than by the air around it. Mounting it solidly to the magnesium frame would cool it, but it would then be unable to move for stabilization. The...

    Tilta shows off a cooling module for the Canon EOS R5

    I have my doubts, but a true test of 8K video run time with and without the cooler would be the best test. If it extends the run time by 50%, it might be worthwhile. 10%, maybe not.

    There will not be an EOS 5D Mark V [CR2]

    I do kind of wonder, though, if they couldn't come out with a parallel body to the R5, kind of like the 90D and the M-6 Mk II share a lot of technology. Then the question is, will it sell...

    There will not be an EOS 5D Mark V [CR2]

    Interesting.... Part of me wants a 5D Mk V, but with the R5 coming out, and assuming it's as good as it sounds, I probably would opt to stick with the mirrorless over the 5 series DSLR at this point.

    Here is the Canon EOS R5 and Canon EOS R6, along with the announcement date

    Looking good so far. I'm not interested in the slow super-telephoto lenses at this time (that can always change, of course), but the R5 is of great interest to me. Really waiting for something that will present an improvement over my very decent Sigma 150-600 lens.

    Sooooo, f/11 you say? What’s Canon up to with these upcoming supertelephoto lenses?

    One more thing to point out - if you have the 100-400 f/4.5-5.6, you already have available, with a teleconverter, 560 mm at f/8, and 800 at f/11 using the 1.4x or 2X respectively. Same with the 400/5.6L, but without IS.

    Sooooo, f/11 you say? What’s Canon up to with these upcoming supertelephoto lenses?

    I pointed out on the other thread discussing the new lenses, but I'll repeat myself here: I like birding. Sometimes, in very dark forests, even at high noon, I'm needing ISO 3200, even 6400, and on rare occasions, 12,800 to get the shot with my 5D4 and the Siggy 150-600 (f/6.3 at 600). Simple...

    This is likely Canon’s lens roadmap for 2020

    A 1.4X teleconverter costs you 1 stop, so your 5.6 would become f/8. A 2X teleconverter costs you 2 stops, so you would then have double the focal length, but at f/11.

    This is likely Canon’s lens roadmap for 2020

    Ok, so lets say you're birding in the dark shadows of the woods. You need some shutter speed so you're shooting at 1/1000, f.5.6, ISO 3200 for proper exposure. Lets go to f/8 - now you're at iSO 6400, or you give up more shutter speed. At f/11, you're at ISO 12800 for the same exposure. Unless...

    This is likely Canon’s lens roadmap for 2020

    F/11 doesn't really make sense to me. I mean, yeah, the AF might handle it, but unless the high ISO performance of the new bodies is 2-3 stops better than my 5D4, then it won't be useful for birding in the dark shadows of the forest. I'm already in situations with the Sigma 150-600 because of...

    Samyang announces the AF 85mm f/1.4 for the RF mount

    Glad you said that - I was thinking it also. People often forget the R&D costs and initial tooling that goes into manufacturing a lens, camera, or anything else really (including medicine, but that's probably not for this forum). It is a fixed cost, and is spread over the sales of multiple...

    Samyang announces the AF 85mm f/1.4 for the RF mount

    I saw a review on the Sony version - decent lens. Is it better than the 85/1.4 IS EF lens though?
