    I just ordered a M39 jupiter 8 lens on ebay the other day. This is the one i bought

    http://www.ebay.ca/itm/281689271705?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

    I have a few questions about this lens, most importantly, do those "cleaning marks" or scratches on the front anything to worry about? Otherwise is the condition of this lens good? The rear element looks perfect but i am just worried about the front, with all those scratches. However it seems all of these lenses i found on eBay have scratches of some sort on the front element. Spending more doesn't seem to make a difference. Anyways, i just wanted someone to look at this lens for me. Thank you

    Judging by the images in the listing, this lens appears to be in decent condition. Obviously the proof of the lens will be in the shooting (or more specifically the images), but I would generally not be overly concerned about the impact on the final image of small scratches on the front element. You might want to check out this article to see how a lens with an exceedingly dirty front element can still produce decent images.

    OK. Thats mostly what i figured as well. I remember that article from a while back. The thing is, its hard to tell in the photo, but are those scratches deep or are they fairly light? Because from what i have read the deeper the scratch, the more chance it will affect image quality. Is this true?

    Obviously, this is true as a deeper scratch is going to be more likely to cause greater distortion in the bending of the light. However, based on the auction photos I'm not seeing any extreme scratches in that front element.

    At this point, the lens is yours, so I'm not sure what difference any speculation of how it might perform really means anything. The only thing you can do at this point is wait for it to arrive and try it out.

    Yeah i guess that's true. I don't honestly think i will be able to find one in perfect condition. Something this old cannot be in 100% condition.

    You can get away with a lot on the front element. Damage to the rear element tends to cause more problems. From the photos I don't think you'll see any effect from the scratches.

    The scratches look pretty minor. With patience there are better examples available, but I don't think that level of scratching will have any real observable impact. Fit a lens hood though!

    I have a ltm version of the jupiter-3. Quite a few cleaning marks on the front element. The glass in the front element is apparently quite soft. I would need a second copy in perfect shape to say whether or not these cleaning marks affects it, but it doesn't seem to affect my joy of using it.

    The link doesn't work anymore, but I wouldn't worry about it too much. I have an FD mount Vivitar 80-200 that has a front element that looks like it was casually sandblasted haha. It has a fairly large area of pretty deep pitting on the front element...and it still has excellent picture quality. I'm guessing scratches/pitting would cause weird ghosts/flares, but other than that...meh... :D
