Attached are photos using iPhone 4.
There are actually two blemishes; one to the top panel to the right just below the small display window (third photo), and one on the left side of the viewfinder towards eye piece (fourth photo).
Focus accuracy has been verified by Mamiya in Japan two times, but it turned out the problem was with my 45mm D lens for which they replaced the lens elements, see separate sale.
Condition can be described as like New after around 2000 exposures use. Standard 645 focus screen is included.
Please feel free to ask any questions and I will do best and honest in describing. F.y.i. I am Swedish and offer for sale when travel to Sweden first, and if not sell during that time, later from Hong Kong where I current live.
Thank you.
Regards
Anders
