Thanks everyone for the feedback. I have been in touch with the seller. She tells me she is selling it for a friend who bought and never used it. But the seller said she has used it once and loved it. She says it is light tight and in working order. Bmac she says 90mm lense sound right? Paul thanks for the VERY useful information. I am the type who would try to straighten the mirror.If I cock the camera before I remove the lense will both stay cocked afterward or will I have to cock them both again before reuniting them? Anywho, will be sending the payment sometime soon will let you all know when it comes in. Thanks again!
