DOF is one of the fun challenges of macro photography.
I am looking at the new IOWA https://www.dpreview.com/reviews/venus-laowa-15mm-f4-wide-angle-macro-impressions-and-samples
Claims to be the widest macro - and tilt to boot.
Wonder if DOF would be any different with a lense like this?
This photographer speaks of "deep depth of field" with the macro of his bugs. Very interesting video: https://www.youtube.com/watch?v=PZcYXUMkhek&t=213s
Not outrageously priced either - but all manual. I have tried it out - worked on my D610.
For me, 50mm on FX camera body is already challenging. 14mm I am not sure how to shoot a moving object. haha
