As requested here are some of the first images I took with the Samyang f2.8 100mm macro lens.
These are all jpegs straight out of camera (no processing) and hand held. I used iso800 to get a reasonable speed but the IBIS made a big difference.
I have to say my main problem is the limited depth of field and focussing hand held is difficult.
Using the MF assist I have experimented using Focus peak highlighting and Digital microprism. I have found the latter to be more useful when very close.
The toadstools are appx. 2cm diameter.
The lilly flower (DSCF9402) is appx. 5cm diam.
The Salvia flower (DSCF9439) is appx. 1cm diam.
Thanks for your interest jerryy.
