A 60mm Fieldscope EDIII seems like the natural solution. (Be sure to get the ED version!). Lightweight and compact. Your 30x EP will work fine in normal birding light, not so good in low light...

I guess that the 7x42 will be a bit brighter (31%) than the 8x42 from the beginning because of the larger effective f-stop. But when the eye pupil is the limiting f-stop of the system they will look...

Interesting figures.
Makes me wonder why Zeiss never gave us a 7x42 HT?
Maybe they put all efforts in the 8x54 HT instead.
If I only could own one binocular, it would be a 7x42.

If small size and weight is very important the TZ70 is an alternative but don't expect to much of the image quality. Handling is a bit finicky and slow as well with a small viewfinder. Any fast...

Nice shots at ISO6400. 1/5000th sec is probably on the safe side, the portrait at 1/2500 is definitely safe for motion blur but with the D5, high ISO is no worries.:t:

The "tunnel effect" is a good term to use for explaining the "feel". Most people don't like a view that feels like looking down a drain pipe. Too high AFOV might cause problems though, as you might...

Yes, roughly and relative, but the formula is an approximation so the figures you get from the formula might differ with the actual specs/values you can find for many binoculars.

Is there an emphasis? :smoke:

My feeling is that the use of DX is increasing since the IQ is often good enough even at higher ISO (D500).

FF still is useful when you can get closer to the subject....

Panasonic claims 6.5 stops with DualIS in the Lumix G9 up to 280mm eqv. focal length.
6.5 stops seem to be the limit of what is possible in theory is my impression.

Sony IBIS is clearly behind Pana...

Did you see any rumors on nikon IBIS?

I'm not sure they will do it, at least not in FF bodies.

ISO performance is good enough, VR in lens is enough.

MFT cameras is more in need of IBIS.
And maybe...

I have been wishing for longer and lighter f5.6 lenses for several years so it looks really interesting.
A 500mm/5.6 at around 1.5 kg would be a very nice tool for walk around bird photography.
