Anybody with any experience with a Tamron SP 17 - 35mm f/2.8-4.0 Di?

 

I'm intending to use it on a D700 body.  I've read some good things about it.

Get a good copy and it's a great bargain. On a D800 for a filterable ultra wide. I wouldn't use it on a 36MP body, but it worked well for me ok n the 700.

Got the gear today only to find out none of the software I have PS CS5, Lightroom 4 and Aperture can be updated to work with the D750 RAW files.

Really thinking about going with DXO Optics first before sticking with PS.  Not really a fan of Adobe.

SOOC (cropped) Samples.  I seem to have front focus issues with this Sigma 35.

Yeah I will use the LensAlign system when I get a L Plate so I can set it up on a tripod.  Should be able to get it right if it is not too far out.

^ Yep, and the Sigma dock will also let you adjust it at different distances, as well as update lens firmware. I stopped using mine, except for firmware update, when it apparently reset the adjustments I'd made without my permission. Could very well have been a user error, but I just use the in camera adjustment since my lens had very little differences at different focus distance.

Does the sigma software let you tweak at different F-stops too? 

 

For lenses that focus perfectly at F(max) but front/backfocus at F(2 stops less)?

^ Unfortunately, no. That would've been a nice feature, though. No wonder if they could add it with future updates.

FWIW, the Sigma software interface is terrible. A better translation/localization to English would help greatly.
