  • Switch to one-shot AF.  Those are the limits in which face-detect + tracking will work in servo AF.
  • Probably simpler to turn the camera off when you're not using it, as Exposure Simulation is useful. I did notice that my camera stopped down my Samyang 35mm f/1.4 when I wasn't expecting it, but ...
  • There's a simple way to find out...
  • No, I'm saying it wasn't designed to replace a video camera. It was designed to warn the user and eventually shut down before it overheats. Expecting extended 8k or 4h HQ running from a camera like ...
  • If it were designed to overheat, there wouldn't be any warnings or shutdowns, it would just keep going until the circuits fried or the battery caught fire.  It was designed for stills and short ...
  • Replied in R5 vs R6
    The other thing to remember is that digital cameras are still improving and getting relatively cheaper.  (Relative to the price of food, drink and shelter.)  An EOS R6 should give you smoother ...
  • Both you and Joe left out a zero to the right of the decimal point.  It might have been clearer to write 1000ms/120 = 8.3ms.
  • But the square of the voltage is always positive, so the power output fluctuates at twice the AC frequency. A fluorescent light, rather than an LED, would guarantee a 100Hz or 120Hz flicker.
  • Hi Manzur, I like your photos. EF lens IS works just as well on any adapter that will power it as on a DSLR, but no better. The first EF lenses were built for film cameras, so the IS unit is ...
  • It's not just your sample, it's the lens design. I tried it out in February 2019 and sent it back, because the Samyang 21mm f/1.4 was doing a better job mounted on an EOS M10 for astro  than the ...
  • I've never tried to set any camera to just use the EVF because those things generally take more power than rear LCD screens. The rear screen switches off while you have your eye to the viewfinder ...
  • My EF lenses are obviously better for IQ and focussing adapted to the EOS R than they are on the EOS 5Dii.    While the EOS R6 should be better than your 7Dii for speed and focussing, you will ...
  • Sagittal (arrow-like in Latin) might better be described as radial, which would make more sense of tangential.  Resolution can be different depending on whether you're measuring it towards the ...
  • Just two lenses.  My Jupiter 8 (Sonnar 50mm f/2 clone) definitely covers the whole sensor. I sent back a 7 Artisans 35mm f/2, not because it wouldn't cover the sensor, but because I was getting ...
  • The main thing to look out for is to switch off all in-camera lens aberration corrections.  According to https://www.lensrentals.com/blog/2012/08/canon-illumination-correction-and-third-party-lenses/ ...
  • Surely you can do the same thing with an RF lens too. It's just like cropping afterwards without the flexibility of second thought about the framing.
  • Their server certificate expired last month. Try https://stephen-westin.com/misc/mounts-by-register.html or camera-wiki.org/wiki/lens_mounts
  • The drawing is great, a model of clarity. The blue dimension is the one you want, the red dimension is completely irrelevant. According to https://www.graphics.cornell.edu/~westin/misc/mounts-by-re ...
  • I was measuring to the ring inside the lugs.  If you look carefully, near the end of the ribbing, you will see that the lugs are a little bit shy of the mating surface that is the inner ring.  ...
  • That would be a reasonable argument if the lenses were ten times the price. Here, the price difference is a couple of dozen extra value hamburger meals. The 11-22mm is so much more handy, fun and ...
