screw on filter or filter holder

[rmcheek]

I want to get some filters nd, polarizers, uv but I'm not sure if I should spend the extra money on a Corkin filter holder as I would probably buy the z pro series because its better for wide angle shots or just go with a simple screw on type. What do you guys think? Is it worth the extra money?

Most Quality screw-on are made from optical glass, while most "square" ones are plastic.
On the other hand some filters like grads are difficult at best to use as a screw-on.
Square types( Unless very expensive mounts) provide no lens hoods. Those that do are compromises at best.


SO I use screw-on where possible and "Squares" where absolutely necessary.

I use screw on , as elmo said most are glass and you can use a lens hood at same time.

Alright screw on it will be because they are much cheaper and I'm a poor college student. Thanks for the help!

I would NEVER get a screw-on (graduated) ND filter because it forces you to put the horizon right in the middle of your shot, which is usually not where you should put it. I have a graduated Lee 2 stop ND filter that I hold by hand. It is resin, not glass, and cost $90. You get what you pay for.

Most pros on this site do not recommend a UV filter because a cheap one can degrade your image quality and a hood will protect your lens better and reduce glare.

If you get a circular polarizer, B+W are the best and Hoya if you're on a budget. I know this stuff gets expensive quickly, but you don't want to put a cheap filter on a good lens.

p.s. - The Cokin filter holder is really the cheap one if you compare it to the Lee filter holder.

WOW I find screw-ins are more expensive.

AS for terminology: An ND does not have a line across them to place in the middle it is the same shad all the way across. A GRAD has the different values across the filter and yes the only way to go with them is "Square".
