Re: Reikan FoCal AF-tuning of 2x Sigma 35mm/1.4 on D800

Hello,

I've just tested my new Sigma 35mm/1.4 on a D750 with FoCal and had rather discouraging results :

The software advised +6 AF but also indicated that I have Astigmatism issues. I'll run another set of tests again tomorrow to make sure but I get the feeling that this lens is a dud and that I should get it replaced (only bought on Friday so shouldn't be an issue).

Disappointing...

Cheers,

CN
