Adjusting autofocus on Canon XT 350D after IR conversion

I converted my XT to IR, and the autofocus is just a bit off... It's not to bad if I shoot at f8 or more..

I looked and could not find anything on adjusting autofocus. Has anyone seen anything on this or done it before?

Thanks for your response!

If you had it done at lifepixel, they should have calibrated it to the best of their ability. On cameras before the 1dmkiii, there was no user adjustable af correction CF.n

Autofocus can be problematic with IR conversions. Many commercial IR conversions will be optimized for one specific lens.

Probably, the best approach for a camera converted by the photographer or for a camera converted by a company which doesn't specify a specific lens in their conversion is to shoot at f/8 or smaller apertures - preferably f/11 or f/16.

Some of the better manual focus lenses usually had an infrared focusing sale onthe lens barrel. Obviously autofocus lenses don't incorporate IR scales.

I did the conversion myself, and at f8- and on.. the pictures are great... I guess I'll have to live with it... Thanks!
