Hello all, I recently bought a pretty decent-sized lot of camera gear off of eBay for a rather small price. I was mainly interested in a Minolta SRT 101 with a MC Rokkor 58/1.4 and a MC W.Rokkor HC 35/2.8. The camera and lenses are all in fantastic shape cosmetically and the camera is 100% functional, but both lenses have issues. The 35 has oily aperture blades, but I can use the DOF preview to stop the lens down before tripping the shutter and so I'm not that worried about that one right now. The 58/1.4 however, despite not having a scratch on it, won't stop down at all. Nothing happens when I push the DOF button on the camera or if I manually trim the aperture linkage on the back of the lens. Given that these lenses usually go for less than $100, I don't think getting it repaired by a professional makes much sense. KEH will do it for $120 plus shipping, according to their price guide online. I'm wondering if anyone has any experience taking one of these lenses apart and if there's any chance that it might be a relatively easy fix. I don't have a whole lot of experience taking lenses this complex apart. The only repair I've done so far was to a Hi-matic. I do however have a good bit of experience taking other things apart and putting them back together and I already have the micro screwdrivers and a spanner (if I can find it). So, unless anyone knows someone that can repair it for less than it would cost to replace it, I'm really tempted to give it a go. If I completely foul it up, I'm not really out much money. I just hate letting an otherwise pristine piece of glass go to waste. P.S. I know that I could return the lot to the seller, but the rest of the lot, without the two lenses, is still worth a lot more than I paid. I'd even feel bad about asking for a partial refund.
