Sorry, it's yet another filter question. I went to buy some GND filter today and was thinking which Filter Holder + Adapter to get.
1) I am using D90 and kit lens (67mm thread)
2) I am planning to get ND110 filter (77mm thread), as will buy UWA in future for landscape.
3) I need a step-up ring from 67-77mm, in order to use both ND110 (screw-in) and GND (slot-in) with my current kit lens before I buy a UWA.
4) However, shop owner said there is no direct 67-77mm step-up ring. I'd have to get 67-72 and then 72-77. Which he said would cause serious vignetting.
Now my question is, is it true there is no step-up ring directly from 67 to 77mm? And if there isn't, would it really cause vignetting stacking 2 step-up ring? Since it's step-up, I dont really see how it can cause vignetting.
Hope you guys can help! And sorry its another filter topic again...
