Wow, long time no post. Busy, busy , busy! These are from my new (to me) Pentacon 6 (medium format) 300mm f/4 on the *istD. First time using it since I bought it over a month ago. Shots look pretty good, but I need to try it in differing light conditions before I decide. These were shot about 11:00am, so the light was pretty severe & some of the highlights are blown.
