I have two Topcor RE, Auto lenses for my Topcon SuperD 35mm SLR in need professional help. Perhaps someone on this list can recommend a reliable lens cleaning/repair service. The optics are clean and the hardware like new, but there appears to be an oily film preventing the iris from stopping down fast enough. It's not water, so must be lubricant that migrated from elsewhere inside the lens. The lenses in need of service are the 1:1.4 f=58mm and 1:1.8 f=58mm. Thank you for reading this post and for your assistance. Please reply by e-mail to [email][/email] Norm
