Recommend a good quality ND filter system?

[Ari]

Hello,
I don't use filters, with the exception of an occasional ND filter.
With the acquisition of three great 8x10 lenses, I'm having trouble figuring out a good system and one of good enough quality for the lenses I have.
The lenses have filter threads of 77mm, 95mm, and 105mm; the latter two are WA on 8x10 (150 and 210 lenses).

I like the idea of resin filters with one holder for all three lenses, but the largest holder I found is made by Lee, and is only 100mm.
But I don't know much about resin filters in real-world use, maybe they have some drawback of which I'm not aware.

I have a compendium hood for my camera, the filter size is 6" x 5.5" (15cm x 14cm), but anything of quality in this size will cost as much as a modern used 8x10 camera.

What do you use? And what might you recommend?

Thanks in advance.

For bigger lenses, I've used Lee's thin polyester filters in Cambo filter frames. They're 4", which won't quite work for you biggest lens. One option is to use the filters behind the lens, since usually the rear cell of a lens is smaller than the front one. There used to be a filter holder made for just that purpose, the Xenophon filter holder, but it's not hard to DIY. The thin filters are so thin that any focus shift is negligible. An advantage is that extraneous ambient light is kept completely off of the filter.

I use a Cokin Z-Pro filter holder for 100mm Schneider glass filters. For wider lens you'll have to use a Cokin X-Pro holder http://www.bhphotovideo.com/c/search...rch=yes&sts=pi.

There are filter holders that are popular for use with the Nikon 14-24 zoom. Lee SW-150 is one of them 150mm x 170mm. I believe I saw some Chinese made knock-offs of the holder that looked well made.

I use theatrical gels which come in 12x12" sheets. A piece of scotch tape anchors them behind the lens, which is also cheap. I see no need to spend hard earned money on a high priced gimmick filters in order to put them on the front of the lens where they are more subject to damage and reflections.

The Lee 100mm filter system may be an option, using their 115mm press-on filter holder:

I think it can be ordered in the U.S. as well, but possibly as a special order item.

As far as a hood is concerned, I used a Lee compendium hood with my longer lenses, with the large wide angles I used my hat!

Thanks, everybody; if you have any other suggestions, I'm all ears.

After pricing some of these options, I would probably look for a couple of ND filters that could fit in my compendium.

Or, get a couple of cheap step-up rings off eBay, and one variable ND filter of good quality in a 105mm thread size; there's no point shooting with good glass if the gel or filter in front of it is below acceptable quality.

fyi, variable nd's are nothing more than a couple polarisers (linear).

Is this true? I thought anything close to or on the lens is so out of focus it matters little. Such as dust, small scratches and a lesser filter. Obviously we all want perfect everything, but where is the line drawn on IG with front filters?

Rear filters need to be better? Or so I have read...

If behind the lens filters get too thick, then they cause a focus shift. For that purpose it's best to use gelatine or the equally thin polyester filters.
