  • Thanks, Phil! That's a 455B tripod and a 410 geared head, both from Manfrotto.
  • 7D + 37 mm ET + 100 2.8 macro (at f/11) + reversed 50 1.8 II (manually stopped down to f/2.8), 2.5 sec, ISO 400, manual exposure/focus, 455B/410 support. And the set-up for the shot:
  • True, diffraction effect per square mm of the sensor is the same for a given set of conditions, regardless of pixel size. However, I'm interested in and have specified that I'm looking at the ...
  • My limited understanding on the effects of diffraction at the pixel level (in digital photography) is that it's mainly a function of Av (or f-number) and pixel size. See an excellent post on the ...
  • Replied in Looks good!
    Nice detail, considering the reach.
  • Yes, the angle of view of the combo relative to a 36x24 mm sensor is approximately similar to 2,592 mm. Further, if we crop the capture from 24 MP to about 8 MP (the resolution of the old 20D), an ...
  • Thanks! If your display is 4K, you need not resize the moon, just extend the length of the black canvas to 3840 from 3600, then cut  the height to 2160 from 2400. :-)
  • The EF-EOS M adapter doesn't materially add any diffraction effect, although I believe there could be a very small light loss due to the extension tube effect. But the teleconverters are another ...
  • Thanks, Lawrence. IME, you can add TCs to a good base lens and get more moon detail until the combo is f/11 or so for a 20 - 24 MP APS-C sensor. With a 2x TC on your Sigma 150-600, you'd be at ...
  • Thanks Andy, and everyone for the kind comments. I converted the RAW in ACR and processed using an older version of PS (CS6). Yes, the lens had a native aperture of f/3.5 for this shot. The M3 was ...
  • Created discussion thread The moon with an M3 + 1600 mm
    I found some time a couple of days ago to try out a new moonshooting rig - an EOS M3 attached via an EF-EOS M adapter to a 1600 mm f/11 combo (EF 400 2.8 L IS + stacked EF 2x II and EF 2x III ...
  • Shooting info - Rosario, La Union, Philippines, November 15, 2016, EOS 7D MII + EF 400 2.8 IS + EF 2x TC II + EF 2x TC III, 1600 mm, f/16, ISO 100, 1/50 sec, manual exposure, 475B/516 support, two ...
  • The sharpest lens I ever shot is my 400 2.8 IS (I've used an 800 5.6L, a 600 f4 IS I and II, a 500 f4 IS and several copies of the 300 2.8 IS). I've owned and used extensively the 400 2.8 IS and ...
  • Replied in Thanks! (nt)
  • AF slows down a bit with a 1.4x III on the 7D II + 400 DO II, but it's still fast enough for fast action. Here's an 8-frame burst using a 1.4x III at a raptor dive-fishing . With a 2x III, the ...
