Filter System

[Sarnia]

The only filters I use are UV filters (to protect the front lens element) and I've always done this on my lenses for my A900 but I'm wondering if a UV filter will degrade the image quality of my Alpa lens?

OK, this is a very old thread, just trying to get what opinions still linger.
So for the STC / HR40, HR70, phaseone 80 and 120 TC, would the sev5n system from Lee suffice, or should I go for the 100 system ? Any other options for long exposures and grads ?
thanks

On my HR40 / HR70 I use the Lee holder. I got a wide angle ring for the 40 and a standard for the 70. The holder is 3 slots and the polariser ring on front. I get no vignetting with this set up. If the Schneider holder is the same you will have no problems.

For filters I use Lee ND grads (0.3,0.6,0.9), Lee Big Stopper (just got this) and some Hitech-Formatt IRND filters as well (1-5 stops).

As for the system I am not too sure on the sev5n. I use the 100mm setup so I can transfer to my DSLR as well if I want to. I don't know if the 75mm filters would work too well if you stack a few, maybe others can help on this one.
