The X-700 was a freebie to me. It came with a Tamron 35-70mm zoom and I already had a stash of Pentax (and a 135mm f/2.8 Meyer-Pentacon) M42 lenses. So, the adapter was the cheapest way in for me. It is a very nice camera and still does auto shutter speed with my M42 lenses.
There are a lot things I have not in my sig since it would make my sig longer than most of my posts!
