Can anyone tell me from personal experience whether or not the matte surface of Katz-Eye screens is better for manual focusing than the matte in the stock B or E screens for the D2x? I was looking at the split-screen possibility, but Rachael Katz informed me that there is now an all-matte screen available. I would really like something like the old D screen, something with "bite." Also, does anyone know if the matte surface is usable for manual focusing in the Kodak 14n or SLR/n (similar finder to D100)? Any thoughts on the extra brightening treatment?
