Alright, found a cheap screw on rubber one
Seems to work well, good purchase in my mind. Also got a Promaster 81A.
I don't have a convenient way to convert to .jpg, I'd have to do every single file individually in gimp, and I don't want to do that. Additionally, I have no RAW experience, so I'll probably shoot this wedding in .jpg.
Never heard of a "black net" filter. Is it anything like a promist? I've used promists on a videocamera, they help with contrast and whatnot, nice filter.
I'll be going back by the store this afternoon, I might swing in and pickup a step up ring so I can use the filter and hood on my 50 and 28, which both use 52mm threads.
