Has anyone tried using a DA lens w/ Lens Turbo on a NEX? I understand there's no aperture control, but I'm still surprised that I've been unable to find any reports about frame coverage. I'm particularly interested in what the DA primes look like on one. If you got em, mind posting a photo here?

Which particular DA lens you have the most interest to try out with LT? I have DA 15, 35, 10-17, 50-135. I don't use LT on DA for the obvious absence of aperture control. And I will try LT out with DA 35 and 50-135 when I find the right occasion. The LT works out great with many SuperTakumar, K-mount and FA limited lenses.

The most issue for me come on the blue central spot especially shooting into lighting at night. Another issue comes to field curvature that may aggravate the lens barrel distortion. Corner performance is another issue people talk about but I find it the least problem for my type of shooting.

Cheers,
Hin

I've got the 40 and 10-17, but no others. I'd be interested to see what the 15 and 35 look like. Maybe even the 10-17 as a lark. :-)

Lensturbo + DA 40mm XS works fine. I forced kept aperture wide-open using a rubber stopper though.

DA15 vignettes quite a bit on the A7.
I was hoping it would actually have a bigger image circle that would give me close to 20mm on FF but it did not. (It would be heaven if it did, considering the size of the lens)
I'd say, its roughly the 22mm equivalent that it is covering aps-c and not much more.
