There are 3 distinct types Mike.
1. single density screw on glass
2. circular multi-density screw on glass
2. single density mylar/plastic that fits a holder (and become multi-density by adding more than one to the holder..
Each type has both cheap/expensive in their lines...
IMO... it becomes a matter of budget/compromise between the densities you want, and the type you decide on...
I use cheap CAMDIOX ND1000 (10 stopper) in the daylight. On a sunny day with a small aperture I can get long exposures up to 30 secs. Some cheap ND's are known for there bad colour casting but these filters give no colour casting at all and are a bargain. I think I paid about £13 for a 77mm one.
I have a Cokin A series left over from 1979. Been thinking of ND filters and they have 1, 2 & 3 stop filters. I think they have holders for CSC cameras, but can't find specifics.... yet.
Not going with Cokin as for some reason the lens hood on my 10-30 is a real pig to remove and refit,i can screw filters on with it in place though
Have you thought of going for a variable density one.
I have one that goes from 1 to 10 stops. It wasn't expensive and it works great when you want to do long exposure shots of water.
Yes Mike just search the size you need on EBay. Bit of a wait from China but cheap and good quality.
Which one did you buy? I bought a variable one a couple of years back and it was awful. I plan on buying an ND filter of some kind when I visit the camera showHave you thought of going for a variable density one.
