Re: D300 with Sigma 30mm - Outer Af Points not sharp

I have exactly the same problem with my Sig 30/1.4. One would think that using the side AF points would be better for adjusting for the field curvature than simply using the center and recomposing, but it seems not to be the case.

I have the same problem w/ my Tokina 11-16. Maybe in all lenses w/ noticeable field curvature the side points are not usable?

Hope some of the more knowledgeable amongst us will share some light on this issue.

Best regards,
Sveto
