You show so many great images! A joy to watch them.
Some, in particular the one of Анастасия and this one of Valery, have an impressive amount of plasticity. I would love to learn how you achieve it, in shooting and then in post-processing.
Never a good feeling posting pictures right after @alexander_ross (love your edits with such a crisp finish and professional colour management!), but my daughter just graduated high school which gives me pleasure to share some images:
I got a free rental from my local store after picking up the Z8, and so I rented the 105/1.4 as it was on the short list of high quality portrait primes that could be had for a reasonable price. Took me an afternoon to go ahead and pick up a used copy on MPB (selling for just $1,049 right now, which is amazing). I've only taken a handful of quick shots of my son so far, but already I'm in love with the way this lens draws. Here's a couple from my testing, on the Z8. The last one wasn't meant to be great art, just testing what could be done wide open near MFD.
