I'm trying to decide between buying coated or uncoated lenses for my Salyut-S. Obviously, the uncoated lenses are much cheaper. I do a fair amount of long-exposure photography at night (all B&W) and I'm wondering if the coatings provide me with any advantage shooting at night. Right now I'm considering a 30mm 150mm and 250mm lens, but I'm shooting a Vega-12 right now, which is uncoated. If there's a significant difference, I might consider replacing the Vega-12 with an 80mm Volna-3 MC as well. I am occasionally getting flare on my shots, but there doesn't seem to be any consistency to it...I can take 3 shots in a row from the same position on a tripod and get flare on one. Also, from what I understand, there is no way to get an uncoated lens coated at a price that makes it a reasonable thing to do considering the lenses cost under $300...is that right?
