Next PZ lens test report: Sigma AF 85mm f/1.4 EX DG HSM - mst - 04-01-2011 Except for the coma, quite an attractive lens: http://www.opticallimits.com/nikon_ff/605-sigma8514ff As to be expected, large portions of the review are identical to the one Klaus posted yesterday. -- Markus Next PZ lens test report: Sigma AF 85mm f/1.4 EX DG HSM - Guest - 04-01-2011 Would you recommend it over the Nikkor 85mm 1.4D?

Yes and No (IMO). -- Markus Next PZ lens test report: Sigma AF 85mm f/1.4 EX DG HSM - Klaus - 04-01-2011 [quote name='mst' timestamp='1301661092' post='7290'] Which one? The Sigma? No and No. The new Nikkor? Yes and No (IMO). -- Markus [/quote] BTW, I was quite surprised that the Sigma had no significant focus shift. That's more an exception to the rule in this aperture class. Next PZ lens test report: Sigma AF 85mm f/1.4 EX DG HSM - Guest - 04-01-2011 Thank you for the review! May I ask you you to have a look at the photo attached? (f/1.4, OOC, just converted to JPEG in NX2) I own the Sigma and use it with a D300. My only real issue with the lens is a huge amount of purple CAs that are often very visible when shooting with f/2 or faster. Would you consider this as "normal behaviour" for this lens? I also have worse examples... Although you can usually get rid of the effect with Capture NX2 you often loose color information doing so. Besides that on DX I have the impression that the borders a pretty good. Like the lens alot! Thanks you, Markus EDIT: Just for the record: This is, how it looks after setting "Korrektur des Farblängsfehlers" to 75 in NX, and applying some sharpening and denoising.

In your sample, I'm not sure if this is fringing or simply "normal" LoCAs. I have the feeling the focus is a tad behind the bike. This would explain the magenta casts in front of the focal plane. At very large apertures, it's rather difficult to find a subject flat enough to completely fit into the thin DOF. However, I must admit that NX2 did a remarkable job in removing the magenta casts.

A DX review is coming, too (both in Canon and Nikon mount). -- Markus Next PZ lens test report: Sigma AF 85mm f/1.4 EX DG HSM - Yakim - 04-01-2011 [quote name='mst' timestamp='1301661092' post='7290'] Which one? The Sigma? No and No. The new Nikkor? Yes and No (IMO). -- Markus [/quote] You mean that the 85f1.4 AF-S has significant focus shift and you'd still recommend it over the Sigma? Why? Next PZ lens test report: Sigma AF 85mm f/1.4 EX DG HSM - Guest - 04-04-2011 Thanks for the test, Markus (and Klaus, of course), great work. Results are just as I expected it. I'm looking forward to the AF-S review. Christian
