Hi,
Iv'e had a reason to check my lense Autofocus accuracy and found this blog with downloadable charts which really simplified the task at hand for me (as someone who had no idea where to start) so perhaps it maybe useful to others ...

If anyone has anything to share on this subject all hints appreciated

Thanks for the link Deb. I coincidentally was reading about AF accuracy this weekend as well. For a commercial solution, on the expensive side, the LensAlign solution seems to work for those that can make use of microadjustments, eg D300/D700 and others. These links will take you there:

http://www.rawworkflow.com/lensalign/ (manufacturer and lists cameras that can have microadjustments)

Cheers,

I am not too sure about these focus charts for general focus testing. They are handy for testing the overall alignment of the cameras internals but for testing focus for the real world I prefer to use a bigger target and shoot from distances that are closer to where the camera and lens is going to be typically used.

Cheers
