  • "In comparison with that mount [the EF mount], the RF mount's inner diameter is the same at 54 mm." It's the flange focal distance which has come down from 44mm to 20mm. So the only real change is ...
  • Resolving ability. These modern high resolution sensors are causing a ripple effect into the glass. What's the point of having 40+ megapixels if the lens can only resolve 30? I dont know if the ...
  • https://kenrockwell.com/canon/eos-r/lenses/50mm-f12.htm The falloff samples and comments are about halfway down the web page. KR doesnt talk about "vignetting" but he does talk about "falloff". I ...
  • Prob non disclosure agreements.
  • I thought the R mount was just to make it impossible to adapt future Canon RF lenses to other manufacturers' bodies. So the mount is doing its job as long as nobody is putting RF lenses on Sony E ...
  • TC saved my asss once -- took a wet curving onramp too fast in the middle of rush hour traffic and then felt my rear wheels sliding to the left. It was a sinking feeling because there was no way I ...

    Can you show us how lens stabilization compares to IBIS when all you have is an nonstabilized lens to work with like an old EF lens or a new AF 50 1.2 or 28-70 2.0?
  • So how can any of us, other than the photographer or somebody who was at the scene of the photo when it was taken, know how good the colors are?
  • who wants the colors of the scene I am photographing and not some colors that a camera company thinks I would like better?
  • If you arent shooting people, or you are shooting people with helmets, or costumes covering the face, and cant get eye or face detection to work, the A7R3 has "focus lock". You place the focus ...
  • Replied in IBIS?
    Some people just can't understand what advantages they are losing from not having a feature, and really don't want to understand it. Their logic is usually the same: they take great photos with ...

  • Isnt Rockwell known for including some pretty inane statements.
  • Oooo, interesting. Then more experimentation is needed. I have never had a camera with CRAW. But it is possible a firmware update could fix this or a workaround of just not shooting CRAW. Thats ...
  • Probably around 5kg. Canon has a 200mm f2.8 which weighs .765 kg and a 70-200 f2.8 that weighs about twice as much at 1.490 kg. Canon also has a 200mm f2.0 that weighs 2.5 kg, so if everything...

  • Hopefully it is just the result of a poor RAW converter. But doesnt this look like a common problem with older sensors like the 5D3? IIRC one of the advantages of the 6D over the 5D3 was a lack of ...

    And, to a cynic, it gives Canon something to add to the EOS R Mark ii, to justify EOS R owners upgrading on the next iteration. :)
  • Replied in IBIS?
    I think some cameras are designed with the expectation that you will be using an external (and expensive) stabilized gimbal mount. I do believe that image stabilization is important in video, but ...
  • Replied in Yes -- IBIS.
    And it will cost $500 and the focus performance will never be as good as with a Canon body, especially with an older non-IS EF lenses which benefit most from IBIS. :( I doubt the gain from having ...
