Hallo Rainer,
I like the situation that you captured, and as always your picture is technically excellent. Won´t be saying anything about the composition, has been done enough above. The 6x6 shot I find altogether the better one, also due to the limited depth of field. Perhaps, you should invest in a second M-body so in the future you could carry both Trix and something like FP4 ?
Best regards, C.
