Recently I got my Schneider 110mm XL and 210mm lenses. I found that the aperture ring of 110mm XL is much looser than the 210mm lens, the aperture ring on 210mm lens gives me really good feeling. I wonder if it might cause exposure problem, (I haven't used it yet). Thanks.

my 110 is the same way and i haven't had any problems. i've never seen this on another copal shutter before. strange. unless yours is so loose it moves without touching it i wouldn't worry, just be aware when you are setting the lens.

If the loose aperture ring bothers you then take it back to the dealer you purchased it from and see if he can get it tightened a bit or can exchange it. Or, photograph with the lens and see if it works OK. If so, then you can decide whether or not you have to get it tightened a bit.

You could also carefully untighten the retaining ring behind the lensboard and insert a small piece of blotting paper as a brake behind the shutter. Be aware, if you do so, that the glass of the back element protrudes the screw when it is unmounted.

I just got a 110XL as well and found the same "problem." But so far, in my early shooting tests, it does not seem to have any effect on the photos. The lens seems to be wonderful!

On my Schneiders some are relatively tight, some are relatively loose, and some are in between. Will it effect your pictures? No, not at all, so long as the iris opens and closes when you move the lever, which I am sure it does. Once you set it (even on the looses ones) it won't slip.

a little spacer behind the aperture helps(schneider has very thin metal spacerson some lenses), you isert it netween front element and lens board, it doesn't affect the internal dstance of the lens, so don't worry too much other than that it only improves the "feel good" factor, don't exagerate with the spacer otherwise you cannot turn the aperture anymore

I'm currently making the jump into 4x5 and this was my first choice for first lens. But boy, loose aperature rings, filter size problem issues (according to multiple posts on this site), and I'm thinking what's up with this lens. Are there other issues as well? I know this is a question rather than an answer - sorry. Hope you resolve it.

Cedric: This is a great lens, as many of the archived comments attest. (Though I wouldn't make it my first lens when starting out in 4X5...) The aperture scale adjustments vary in stiffness from lens to lens, that's life. One photog's "loose" equals another's just right. Tastes great, less filling, tastes great, yawn. Put a step up ring on that 67 mm front and put a 72 mm filter on it. Problem solved. The fact that Schneider might have made the outer ring a tiny bit taller to avoid problems with SOME filters is a valid point, but this is still a great, sharp lens with a ton of coverage.
