Macro use a macro lens AF or MF

unapye · 12-11-2014, 05:15 AM

Question to the users of the autofocus macro lens.
Do you often disable the AF and focus manually?
I wonder whether it makes sense to put up for sale among Pentaxians, my Leica macro apo elmarit 100/2.8 converted to the Pentax K mount using the Leitax.com part. Or should better undo the conversion and ask someone to issue on ebay.

I think depends how close you are getting. Once you are so close, af just can't be accurate enough

Manual focus. Period. AF changes field of view.

For close up stuff, it's MF 100% on the time. I only use the AF on the DFA100mm for 'normal' shooting like portraits of humans.

The conversion process is fairly simple isn't it? Do you still have the parts needed?

The is a general consensus that macro requires manual focus
