Camera and lens calibration

(1/4) > >>

elsa hoffmann:
I have (to date) always checked my camera and lens combinations myself, but from time to time doubt creeps in about how accurate I am.

I know there are other ways to check and tune - one being FoCAL calibration

Does anyone have any experience with this or any other software/device/method?

I use FoCal. Makes the process much easier and faster.

elsa hoffmann:
Afx - which version do you use?

Standard, Plus or Pro?

Les Olson:
There is a method set out at http://www.northlight-images.co.uk/article_pages/cameras/1ds3_af_micoadjustment.html which I have found excellent - and which is free.  Its advantage is that the interference method makes the point of optimal focus unmistakable, so once you have the camera set up square to the screen you can do a series of lenses very quickly. 

Andrea B.:
Free is always good. Thanks for the link, Les. Looks like there is a lot of info there.
