110XL and 67 Filters: Problem?

[Tom Stanworth]

I have seen some people comment on problems with 67mm filters due to the proximity of the front element and am a bit confused about what they mean. I have a 110XL but bought it immediately before ending up oversease so have neither seen nor used it in 2 years since it was bought. I am now a convert to B&W MRC filters and am considering getting some 67mm filters for it, so:

Is it a case of the filters making contact with the front element and causing damage, or//

The glass being so close to the edge of the barrel causese aa reduction in usable circle if you use filters that are not that thin.

I will be using it on 5x7 mainly so either could cause a prob. If so it is no bother for me to standardise on say 72mm filters and get a step up ring to give more clearance and width if this would help? I dont want to try screwing on one of my 67mm filters if it risks hitting the front element and scratching it!

Any thoughts?

You could call Schneider ,or a US seller, or ask at this address: www.schneideroptics.com/ask.asp?loc...merce/CatalogItemDetail.aspx?CID=169&IID=1836 for a definitive answer on whether there is a danger of contact to the front element.

With the XLs, there's so much coverage you could - as you say - use a step up to both avoid vignetting and address the issue of pushing the filter forward a little. I might suggest going up to 77mm or 82mm to get way out of the way of the huge angle of view of the lens.

If cash is no issue, hah, then there are two varieties of extra wide filters... the first just has a very thin rim and protrudes less into the pictur area. The second has in effect a built in step up ring, so the back end might be say 67mm thread, and the front might be say 82mm thread. one example: http://www.bhphotovideo.com/c/product/120955-REG/B_W_66040295_67mm_UV_Haze_010.html

Some people, myself included, have used the ring from a discarded 67mm filter as a "spacer" between the lens and the filter. I actually bought a cheap filter (less than $10), and removed the glass--there's a threaded ring inside the filter ring that's easy to remove. I've standardized on 67mm filters, so I didn't want to carry another size just for this lens.

Is this because you were unconfortable with the closeness of the front element or because the filter would otherwise have touched?

 

[Keith Pitman]

Because I was being cautious. I don't believe I had a problem with any filter.

I damaged the front coating of my 110XL with my 67mm B+W Polarizer years ago. Since then I use an empty 67mm filtr ring as spacer.

 

[Scott Squires]

I layed a thin piece of tissue paper on the face of the lens and slowly screwed the filter on. The filter hit the tissue before it became tight. Too close for comfort! It makes sense to us a filter spacer with the 110 XL.

I did something similar to Scott for a Kowa 40mm. It was reported some filters hit the lens some didn't.

I went to the local big box and looked at rubber o-rings. I found a small diameter one the right size for the filter. Then just screwed the filter down against the o-ring.

Never came loose, although I didn't have a tissue if I needed one , worked for many years until I sold the Kowa system.

Just 2 cents worth.

all,

Thanks for the tips. I think I will standardise on a larger size then and use a step up ring to be sure. Silly Schneider, that's quite an oversight! I have heard a few people mention probls with teh polarisers so dont know if this is because the filters close in further or what, but even tho I use mone filters only pretty well (when not using a LEE holder) stepping up makes sense.

It is probably because they expected people to use the center filter with the lens. It has a natural spacer built in.
