Actually most filters ARE COATED, even the cheap ones, just not multicoated. (Hoya still makes some REALLY CHEAP uncoated ones though). The difference between single coated and multicoated filters is extremely slight as with only two air-glass interfaces, the single coated filters have only approx 2% loss/reflection which is going to be invisible most of the time. I would avoid the uncoated ones but I am telling you they are very rare. JCO

Uncoated? HMC? S-HMC? That makes a big difference to the price. I'm happy with the performance of my SMC lenses. I don't see the point of wasting most of that benefit by putting uncoated glass at the first interface to the outside world. It's the old, old argument - why bother to buy an expensive lens if you're only going to stick a cheap filter on the front of it? I probably wouldn't pay $100 for a filter if it were only going on a $100 lens, but my FA 28-105 also takes the standard 58mm filter size. And, unfortunately, it's mostly the cheap uncoated filters that show up at the second-hand sales.
