Been there done that.. with that kind of magnification, AF is almost useless, even with AF macro lenses. I use macro lenses with extension tubes so the magnification is quite high and the DoF is quite shallow and focusing is very critical. If the magnification is crucial, you will even need a macro slider to focus. Best is to have Tilt and Shift then you can tilt to increase the DoF.Originally Posted by Snoweagle
Too bad I am not able to post any pictures to illustrate because they belong to the previous company I was in and there are IP concerns.
