@Tarocco: I am surprised to not see that heavy loss of image quality at the edges of the picture, as in a review of the MB speedbooster by a Fuji user was reported:

Is that only visible wide-open?

Some of the corners are cropped due to stitching but in general I find they're pretty good, even wide open. I also use most of my lenses on a Canon 6D so I'm in the process of making more comparisons. I do see an odd effect where the very center has higher resolution than the rest of the frame, even stopped down - but it's more complex than just 'bad corners'. I think some (not all) of the image quality limitations attributed to the Speedbooster are really just lens limitations.

Here's another stopped down Nex-7 / Speedbooster stitch:

I expected the central higher resolution boost from my Zhongyi FD Lens Turbo, but have also been pleasantly surprised by good edge (if not extreme corner) performance from my FDs. Obviously the lens quality has a lot to do with this! But the one-size-fits-all approach of the LT/SB can surely not produce the same performance on every lens, regardless of each lens' unique field curvature, distortion etc? Anyway, the edges of this FDn 50/1.4 + LT shot at around f2.8 (un-cropped, as far as I remember) are fantastic, especially as I wasn't expecting or hoping for them to be this good! Posting large, just to look at sharpness (embarrasingly, I've only just noticed sharpening haloes and green fringing. Must revisit this one!):

@Tarocco & Alan: Very impressive photos!
Alan, did you only resize or is this a crop?

Un-cropped, as far as I remember, but I can check and confirm later.

That's impressive alan, I may have to get one of those as I'm starting to get a few FD/L lenses. The 3rd shot of your previous series above ( ... F4 maybe?) is another good one at the edges.

A 16mm/F2 Rokinon arrived in the post a few days ago and today was the 1st time out with it on a 5N. I REALLY like this lens

mcbroomf - I'll bet that lens would rock on the new FF Nex.On a crop it looks to be a very capable 24mm

Another grab today.This was taken with Takumar 200 and Turbo

well TG may have been my last nex shoot for a while--A7r came today

DSC01478 by unoh7, on Flickr

Nex 5n has been a fantastic camera for me, and each time I lift the A7r---I wish it was so small and light!

However FF is heaven

Another thing which astounds me is how well the A7r performs at f/16. On the 5n I try to stay around 5.6 shooting landscapes if the edges are there with whatever lens, because I really see the difference past that point.

But the young designers worked their butts off to improve diffraction and it seems to show

This thread has improved my shooting and inspired me time and time again. Long live the NEX image thread!

It's an APSC lens Jim, not sure how much it will cover on FF

One more from Venice. It's on an island called Cimitero (cemetary) for obvious reasons. When you visit it, some graves really touch you.

NEX-7, Speed Booster, Oly 2/21





And one again from Venice itself, Quartiere di Dorsoduro. NEX-7, Speed Booster, Oly 2/21



Enjoy,

mcbroomf, great images from the Rokinon 16mm. I was debating about the Zeiss 24, but that's a lot to drop on the "Zeiss" emblem. I now have a better idea on which one should go with.
