macro flowers

IF you can have the fine motor control to make the minute adjustments to focus the subject.

One solution for that can be a focusing rail. They usually allow micro adjustments with more tolerance in the "focus" knob.

As with all things camera they can be expensive but used ones are usually easy to find.

This lens has a push pull as well as a twist for focus. the push pull changes magnification and is easily knocked out of adjustment.

I know what you are saying about a rail

I also know that on a tripod this lens would be easier, but when I do flowers or fish I like the freedom to be able to move around my subject. Most of what I do is hand held.
