So after 7 years of thinking, I bit the bullet and finally picked up a 4x5 from KEH today, also bought a 150mm lens to start with and 3 film holders. Aside from the obvious such as a focusing cloth and loupe, what else should I be looking at as far as accessories go? How do I go about mounting filters? I have a bunch of 77mm's from my RZ kit that's I'd like to use if possible to save money. I'll be using this for still life, landscapes, interiors, portraits and nudes. What are some good focal lengths to look into. I use a 65, 110, 140 & 210 with my RZ, I'm pretty happy with that combination, a little wider won't hurt either. Thanks!
