Really? I have 500mm F5.6 that at APS-C, 20MP crop becomes 750mm before adding a TC. AF motors die, lenses get dropped so good luck investing in a wildly expensive lens with no servicing. Would you...

Been there done that: 500mm on FF 46 MP cropped (it would be daft to print 1,5 meters wide and cut the little bird out with scissors, no?) to 1315 x 865 (the bird is 500 pixels high) and then...

The more important point for me is reduction in weight rather than shortening of the lens barrell. If it is made collapsible it will gain a little weight and also act as a bicycle pump, which needs...

I bought Topaz and am doing some experimentation :-) I upsampled "The roses"  below to 12.000 x 8.000, i.e. 96 MP from 46 MP just for fun. Tamron 90mm F2.8 @ F8 1/60 sec iso 72 on Nikon Z7 downsamp ...

FF DSLRs generally do measure and stop down as you suggest they should. Things are done differently for different brands with FF mirrorless. Generally speaking it is an advantage with small F...

No way. @46 MP the Nikon S 24-70mm @ F2.8 can pull much more detail out of a scene than the Oly 12-40 or any 20 MP sensor will ever do. With computational imaging more pixels are a huge advantage...

The leader of the pack is Sony's 60 MP sensor. (full stop) You can crop to your micro 4/3 pixel number - while having a much larger field of view, thus making BIF easier. My Nikon @ 47MP is also...

Already done by Nikon: 300mm F4 PF and 500mm F5.6 PF (phase fresnell) lenses that are much shorter and lighter than their non-PF counterparts. 500mm F5.6 is approx. 9.3 inches long vs. 15.4 inches...

Thank you Henry! Those are impressive landing skills - I doubt we will see a drone that can do as well anytime soon.

Thank you! https://en.wikipedia.org/wiki/Scarce_swallowtail

OMG - somebody already put this lens on the Fuji GFX 50R: https://www.youtube.com/watch?v=t3aeEH5yaUc

Interesting on video, and a possible "first": it is possible to adjust the distance marking. https://www.youtube.com/watch?time_continue=96&v=KLg4PGVJocQ&feature=emb_logo

This takes some keen piloting skills! It landed on our newly planted, small palm tree. 300mm with TC 1.7x

Your experience with "many lenses" is overly generalized on this site. What we treasure is factual information on specific lenses. "factual" meaning: posting images and...

Thank you! Great image! Yeah, I have had that experience on DPR. I call them "trolls" :-)

So can this image be saved somewhat? "Round 1" Gave it another dose... "Round 2"

Yes I grog film. The enlarger with autofocus, the paper holder that had a built-in genuine photo multiplier that measured transmitted light through the paper and controlled the duration of the...

I agree, but what I am saying is that - provided shooting raw with great glass ( I assume ) then it is possible to add quite a lot of detail in especially linear, predictable structures like ...

@LookintotheMirrorlessoften
you are obviously just peddling conventional wisdom, and how useful is that? for your comments to be of interest to others, you need to do more than talk: go there and...
