ND filter and longer lens
Mar 2, 2019 15:32:17 #
I have a D810 15 - 35 2.8 and 70 -200 2.8 and want to get into longer exposure using ND filters probably a 6 stop and a 10. They will probably be 77mm from BH and I have all ways liked the quality of B+W. I mean the photograph can only be as good as the cheapest glass in its travel to the camera storage. I know that I should be fine from about 22mm - 35mm and not catch the edge of the filter. But what about all the way to 200mm and some day 500mm? I realize that the filter will have to be screwed on after focusing. And lee has a good app for my IPhone . I just can’t remember seeing pictures using a ND 6 or 10 stop filter on longer lens?

If I interpret your question correctly I say you have nothing to worry about by installing a filter on a long telephoto lens.
Many of the longer telephotos are strugling to get enough light in the first place so an ND filter is not the norm for them.
Others might have rear mounted filter locations to allow use of smaller size filters or filter sheet pieces.
If you do get one to fit the front, it's extremely unlikely vignetting will occur. A long telephoto lens will have somewhere around five or less degrees of view. EG: I think my 500mm is around one to two degrees.
A wide angle with it's larger field of view has a much more probility of problems with filters and their holders getting in the way.

I assume you're talking about a screw on ND? With a D810, and if you get your composition right, even if there is any vignetting around the edges from the filter, your images are 36 Mp, so you can crop out the corners easily and not lose anything important. I have the same issue on a 14-28 with the petals on the lens hood. Easily fixed.

I've done it with my Canon 70-200 f/4 with no problems at all but I used NiSi 100mm filters with the holder. I've used the screw on type on some other lens while I was using the longer lens. I If you don't want to screw the filter on try some xume magnetic adapters https://www.bhphotovideo.com/c/product/969996-REG/xume_77mm_lens_adapter_starter_kit.html I use them and they work great. Breakthrough Photography has magnetic adapters also.

It's the shorter focal lengths that are problematic if your filter is too "thick" - long lenses are never a problem.

Yep, on a 500 mm lens you could probably put a postage stamp and have it not show up.

Regarding the Xume magnetic adapters, they are GREAT!!! If you use filters or ANYTHING that mounts to the front of your lens, Xume magnetic adapters make your life so much easier. Please do yourself a favor and watch the one minute video below. You may be glad you did, I know that I was glad that I did. And no, I don't sell them or have stock in Manfrotto.

If you want the darkness to cover the whole lens, the B+W screw-on filter is a good choice. If you want a graduated filter, then you will want to go with the rectangular ones, which can be used hand-held. For use with a lens hood, the rectangular ones won't work. You may also want to consider a circular polarizer screw-in filter from B+W, although they work best when the sun is at 90 degrees to the lens.
As for a screw-in filter size, 77mm is only good to use on a lens that measures 77mm. For larger or smaller, a separate filter in a correct measurement for each lens is needed.
As you mentioned, focus is often better set before putting on the filter unless conditions are bright enough to allow the AF to function with it on.
