My Minolta 58mm f/1.2 rokkor is stuck 'wide open', the aperture blades will not stop down. I have googled forum posts and found that this is often caused by the presence of oil on the blades, or in some cases a spring? I have been told by a few other Minolta users that this is a simple repair and can be done fairly inexpensively.
Can anyone recommend a good place/person that will fix this? KEH quoted $90 incl. return shipping, while the local guy quoted $140 to send it out. I would prefer to not send it out (I live in northeast WI, USA) and I would like to beat the price, or if I can't beat the price I would at least like to send it to someone who can be considered an 'expert' on Minolta hardware of this type.
Thanks in advance,
