    Hi there,

    I just got a Nikon FM2 and so now I need to buy a step up ring so I can use my 77mm filters on it. I know I need a 52mm-77mm step up ring. My question is whether there is any potential problem with buying a cheap (c. $10) one? Do I really need to spend $47.50 (Heliopan) for a step up ring?

    Not just 'no' but heck no! Get a cheap-o ring and get busy with that FM2. I have a couple Heliopan rings because they were the only ones available in hard-to-find sizes while all other rings of mine are from who-knows-where. Haven't been able to discern a difference.

    It's a threaded metal ring, for crying out loud. Putting a brand on it is just a waste of money.

    If it's brass instead of aluminium then it's less likely to seize, but you just don't make a habit of leaving the Al one on your camera.

    I have fancy ones and cheap ones, and no question, the nice brass ones are smoother in operation, but the cheap ones get the job done.

    that is what I figured - I ordered the $10 version earlier today but just wanted to make sure there wasn't something I was missing.

    I have a bunch of cheap ones all work great.

    Just don't get the plastic ones - the two I have had both broke quickly, were difficult to thread properly and became "wiggly" on a hot day (the plastic was melting). Stick with metal.

    One thing to consider is the seizing problem. It does not happen very often.
    However, if the filter seizes to the SUR, separating the two can be a major problem.

    Seizing typically occurs when two aluminum parts are threaded together (mated).
    The easiest way to eliminate the potential problem is to use a brass SUR if you're mating an aluminum filter to an aluminum lens.

    They make plastic step-up rings? I have not seen any but I am not that surprised.

    I did recently see a plastic tripod. It weighed next to nothing. It also could hold next to nothing!

    Thanks Leigh - my filters are brass so I'm won't worry about it. Also I can't imagine leaving them on for any length of time.

    In one of my weaker moments, I order some from eBay -it cost almost nothing ($3 including shipping if I recall) and lasted one shoot before snapping. The second one from a different seller was no better. I bought some better ones and have never regretted it. I also have a plastic tripod one of my friends bought for me at a garage sale ("I know you like pictures" she said) - I trust it with an external flash and thats about it.

    I often put three or four tiny scrapes of candle wax on the threads of aluminum filters or adapters before first use; the end of a birthday cake candle every inch or so around the circumference. That provides a slight lubrication that works into the thread but otherwise doesn't migrate much and seems to smooth out their operation.

    I would advise not getting too gorilla-like in tightening such rings, just enough they don't wiggle or wobble.

    A tiny bit of candlewax on the threads will ameliorate this problem.

    That's excellent advice.

    Some folks tighten filters like a pipe fitting, causing problems that need not exist in the first place.

    Filters and SURs are flimsy, having no strength against deformation.
    Trying to separate those two parts seized together is particularly difficult since significant pressure will bend them out of shape.
    Filter wrenches may or may not work.

    I bought a set of cheap step-up and step-down rings and too many times, there were vignettes on my pictures. The size of my rings average down between 3 & 5 mm. I don't know what to think of that but I use less and less those rings.

    One thing for sure, what matters the most is the ring size or tightening as DWThomas said. tightening is the rule, so far.
