That is the question.
Does anyone have experience with using both of these type of lenses, and what are your thoughts on the pros and cons of each type of lens?
I'm buying a macro lens , and after much research I have narrowed it down to the Tokina 100mm f/2.8. However it is not an IF focusing lens, which means that the lens extends while focusing.
The internal focusing lenses are much more expensive. I might be willing to spend the extra money if the non IF lens would be a problem bumping into the subject while focusing.
