Resin filters with Schneider 72 mm XL

What are you using to hold resin filters, such as a split ND, on to Schneider's 72 mm XL?

<p>

I currently own a Sinar filter holder for 100 mm resin filters, but this won't work on the Schneider 72 mm XL, because the lens takes a 95 mm front filter, and this holder was designed for front filters 82 mm (or thereabout) and smaller.

<p>

Would Lee's holder for 100 mm filters, which accepts a 95 mm adapter ring, work without vignetting? Or will I have to move to Sinar's 125 mm resin filters and their holders for this lens? Does anyone know with certainty that the 125 mm Sinar system won't cause vignetting?

<p>

Thanks,

Bruce

Have you tried directly attaaching the filter holder to the lens (w/o

an adapting ring)? I think there is enought space in there to do just

that.

I agree with Ellis. There is <a href="http://www.greenspun.com/bboard/

q-and-a-fetch-msg.tcl?msg_id=000MKh">a similar post I asked</a>. Take a

look at the first answer by Rob Tucher. I haven't called Lee yet but

from what he's talking about, there might be a solution.

I have a similar problem with the 55MM APO Grandagon using a center

filter. I do have the Lee System. I called Lee in California and they

are aware of the issue and have a special ring available.that attaches

to the body and not tothe threads. This allows for use of the filter

and not vignetting.....

Heliopan makes 3 different holders for 4" filters. All are a105mm

thread. Heliopan also makes very thin 95 to 105mm brass step-up rings.

<p>

Holder one rotetes and takes any combination of 4x4" glass, gel or

acrylic filters. It has a female 105mm front thread for a hood or

accessories.

<p>

#2 is a non rotating holder for 4x4" gels. It also has a 105mm front

female thread.

<p>

#3 is the 4" brass rotating holder for Heliopan 4x6" glass graduated

filters or any other glass rectangular filters 4mm thick. It also has

a 105mm front thread.

<p>

Heliopan also makes 105mm long and short threaded metal hoods that

screw together. These can be used as spacers to increase the filter to

lens distance for longer lenses.

<p>

The Heliopan metal hoods and step-up rings are also commonly relabeled

by some of the English filter companys and sold under their names but

possibly at higher costs.

Here is an answer that I received from John Alder at LEE filters USA.

The above comment by Bob worths considering too.

Dear Masayoshi,

<p>

Thank you for your recent inquiry.

<p>

We already make a filter holder for the Schneider 72XL. It's called

the FK100. It's very similar to our Foundation Kit filter holder,

except that instead of attaching to an adapter ring, it has a built in

collar that tightens down around a 100mm diameter lens. List price is

$200.

<p>

We don't make an adjustable adapter ring. However, we have a new

product called the Gel Snap, which holds 4x4" filters and attaches to

most lenses with a heavy rubberband. It doesn't hold anything larger

than 4x4, and only goes up to 82mm in diameter.

<p>

The Wide Angle Lens Hood with 1 slot is the "shallowest" of all the

combinations. Or, if you're interested in a hood only (no filter

slots) you can use the hood that is meant for the Foundation Kit

without its rails and attach it directly to an adapter ring.

<p>

Please let me know if I can be of further assistance.

<p>

Sincerely,

<p>

Here is another reply from John about the FK100.

Dear Masayoshi,

<p>

The maximum (and minimum) diameter for the FK100 is 100mm. It was made

specifically for the Schneider XL lenses, but will fit other 100mm

diameter lenses as well.

<p>

A conventional adapter ring will not work with the FK100.

<p>

In every other respect, the holder is identical to our standard

Foundation Kit. It will accept a shade, and I recommend the wide angle

lens hood for the Schneider 72XL. (Part # is WALH. List price is

$289.00)

<p>

You can arrange the slots in any order, just like on the Foundation

Kit. If you use a shade, you need to put a 2mm slot on the outside for

the shade to slide into.

<p>

Feel free to write or call if you have any more questions.

<p>

Sincerely,

<p>
