  • You are really getting into the weeds with the semantics here.

    Bottom line, pixel level sharpness will be an issue with even moderately fast lenses due to the heightened AF challenges.

    Again...

  • You are really getting into the weeds with the semantics/pedantry here. It looks desperate. Just admit you are wrong.

  • 50/2 shooting moving objects is hardly exotic. A 70mm at 2.8 at the same distance or a 200 anywhere closer than 33 feet has the same DoF as 50/2 at 10ft. So like I said the problem is progressively...

  • @HowaboutRAW, no, the dogs were still. But 50/2 is hardly exotic, and 50MP makes that FL/F-stop tough for even still subjects. Especially with an OVF with no focus zoom. So your implication that...

  • For a given distance and F stop longer FLs have narrower DoFs.

    Your example has a DoF of a foot and a half. That's pretty tight. And for tack sharpness it's even tighter. I was just shooting MF...

  • @HowAboutRAW, no, most people shoot at longer focal lengths, with even narrower depths of field for a given F stop, which speaks to ProfHankD's point. What good is 50 MP if the only time you can...

  • The data on Sensorgen.info is a start :-) If you know what you are looking at they present things in a pretty straightforward manner. With DPR's much better site design and technical knowledge base...

  • Yes- check out sensorgen.info... they re-calculate DxO test results to report QE and read noise.

  • Nice work Canon. Hopefully an equally cheap 35 STM will follow.

  • Leica is MF... that combo is irrelevant to DSLRs. No DSLRs have AF F/1 lenses in production.

    You are jumping all over the place. Bottom line phase detection AF works great. If it didn't,...

  • Mirrorless cameras don't have much better AF accuracy, and their AF systems are slower and quicker to give up in low light. Plus F/0.95 is the absolute extreme of lenses in general. From what I...

  • Why would this yield an AF crisis? Canon's AF is the best in the business, and DSLR AF in general is measurably better than the on-sensor stuff used by even the best mirrorless bodies. If anything...

  • Looks really good. Don't have an EXIF viewer here but it seems to have much better saturation than the Nikon and even the Pentax at higher ISOs. Real shame they clipped it at ISO12800, it could go...

  • I doubt the bulk of those MPs actually yield useful info. That setup is probably beyond the diffraction limit wide open.

  • Sounds like a brand insecurity problem. Who cares what brand it is if it works? You don't even know how the lens performs and are already writing it off out of pure fear. If some fly by night...

  • This is silly. So if I use a non-OEM battery or flash I'm giving up my copyrights? As if Canon invented the first 35mm lens.

  • The extra speed would be worth it to me. 35mm is my go to indoor/walkaround FL.
