Topic: Help cleaning lens haze??
I picked up a nice vintage Spiratone 400mm f/6.3 preset long telephoto lens in a package deal on Ebay. It is a T mount lens and came with a Konica adapter; I also bought a Canon EOS T mount adapter on Ebay. On my Canon 20D this lens has an effective focal length of 640mm!
One problem - there is some hazing on the ocular lens (objective lens is perfect). It is a light grey haze, similar to the haze that forms on the inside of the windshield of a car sitting in the hot sun from the plasticizers in the car's interior components vaporizing and condensing on the windshield. The lens sits an inch and a half or so inside the barrel of the lens so I used a Q-tip sprayed with Windex to try and clean it up. That helped a bit but there is still some haze present. Any ideas on how I can remove the remainder of the haze?
The haze is not noticeable when looking through the lens mounted on a camera. I took a few quick pics with the lens on my Canon and they came out OK but I'm sure I'm losing some sharpness due to the haze. Ultimately I'll probably send the lens out and have it professionally cleaned (the haze appears to also be present on the back side of the ocular lens) but is there anything I can do to improve it in the meantime?
