View Full Version : Center filter needed for 90mm5.6XL ?
I recently got a s 90mm5.6XL I only intend to use it on a 4X5 for landscape work , do I need be concerened with a center filter.
I shoot 4x5 landscapes without using a cf on a 90/4.5. I don't encounter enough fall off problems to warrant a cf for that lens, even when using RVP. But there _is_ some visible marginal fall off, and I always keep that in mind when composi ng, especially when using a lot of shift or rise. Your shooting habits may diffe r from mine, and so might your sensitivity to fall off.
At the 90mm focal length for 4x5, some landscape photographers use a cf and some don't. Since you already have the lens, I suggest you just try it and critique your results without the cf. It's your call.

As you've already got the lens, you can judge the results you get. Is there too much fall-off for your purposes? If not, then don't worry about it.
