It's so versatile! Do you use only manual focus lenses?

For insects etc I used autofocus until around two years ago. Before then I was using close-up lenses on bridge cameras and on telezoom lenses on MFT or APS-C, and I preferred autofocus to manual focus almost all the time. Since then I have been using full frame setups which are manual focus only.

For flowers etc I have almost always used autofocus, and still do. (I use different kit for flowers etc.)

Do you use focus peaking to nail the focus?

For insects etc, when it works, yes. It depends on the scene. With some scenes I get no focus peaking signal.

For flowers etc, no.

Can you tell me your kenko teleconverter model?

Teleplus Pro 300. Now out of production I think. I think it has been replaced by the Teleplus HD Pro DGX.

Do you know if the Kenko MC7 2.0 DGX is good?

I'm afraid I don't know. In fact I don't even know if the one I use is good, or how it compares to other models and other brands. That may sound odd but because I use diffraction-dominated tiny apertures I never get to see what sharpness, clarity etc my cameras/lenses etc are capable of producing. Even the very best lenses etc would produce extremely soft images the way I use them.

Can you tell me about your post processing workflow? In a nutshell, do you resize (shrink) the images, adjust contrast and add sharpening to the subject?

My post processing workflow changes quite often - it is a permanent "work in progress". However, this post should give you a good idea of the way I go about it. That is for insects etc. I use more normal apertures for flowers etc and this means I can use a simpler workflow than for insects etc.
