Yes, 400 × 2 × 1.4 = 1120mm. But as mentioned previously, 1400mm (500 × 2 × 1.4) isn't enough to fill a 1.6× crop frame completely. Making the video title image in 35mm full frame would require far more than a bit of crop. Just by eyeballing, I'd say at least 6×, probably more.Its with teleconverters of course. 2x and 1.4 afaik.and a bit cropped after.
Not so sure about that. Atmospheric shimmer is clearly visible in many places in the video. In fact, shimmer would become quite a problem once you go pass 1000mm. To minimize shimmer, you need outside temperature -10C at the very most, below -15C would be better. And to minimize the thickness of air layer you shoot through, the moon needs to be at very high altitude. There are only a few nights in a year with such conditions. And even then, one can expect no more than a couple frames sharp to pixel level across the whole frame out of a few dozen captured. This is stuff is no joke...[...] Still extremely sharp.
The unit above is 800/5.6. 560/4 needs another focusing unit. All combos with this head unit weight 6+kg. Would be quite a handful. Really looking forward to your results.Leica also has a 560 -800 mm for this modular system.
