Pot luck - Two ND center filters

After some years I've finally bought my first ND Graduated Center filter, and a few minutes later a second, both new I'd guess old stock.

A few years ago I made a mistake not buying a filter from Robert White who were selling Schneider's remaining stock at quite low prices (approx £100), I put if off and they sold out.

Yesterday there was a discussion on another forum, essentially they seem to start at $500 and range to $1,500 these days, but non are made any more for conventional LF WA lenses. Anyway a quick Google search and I found a Hoya HMC 2x ND center filter for £30 unused but the filter box/case has been opened, having bought it I then found another unopened for £35 from the same UK shop.

So at last I now will have a center filter to use with the 75mm lens on my 6x17 camera, and another for the 75mm I use for 5x4 work.. Both need filter adapters to fit my lenses but I have these already.

Can't wait to try one with my 6x17 camera, dodging the slightly underexposed edges might be reduced considerably :D

One of the advantages of digital printing is that it's relatively to make a mask and apply this particular correction. As we all know, opinions on any other advantages differ considerably.
May I ask, do you compose and focus without it and then put it one before exposure, as you would with an ordinary filter? Is there an advantage in seeing the corrected image on the ground glass?
I ask because I have one tucked away somewhere. Always best to get things right in camera, if possible.

My 6x17 camera doesn't use a GG focus screen, although you can use one when there's no film loaded, focussing is by the distance scale on the lens helical so I will be able to leave a filter permanently attached. I do have a few accessory range-finders but haven't got around to bothering to use one. It's also maybe 8 years since I last used the 6x17 camera while living in Turkey so time to started with it again it's a format I enjoy using.

The disadvantage of the 75mm Super Angulon is the fall off on 6x17 at the edges is more than with the same lens used for 5x4 at the corners. The amount of underxposre due to fall of means you need good contrast control and slightly more exposure & less development helps. It's as easy to dodge though with darkroom prints as with a scanned negative.

I have a cone for a 90mm lens as well but find the 75mm suits me more, in fact I don't use the 90mm with it. 75mm is really a "Normal" focal length for 120 film in the 6cm vertical plane but great for wide panoramics in the 17cm Horizontal plane. I'm usually working in tight spaces where 90mm would be that touch too long.

The Hoya Center ND filters arrived an hour ago, the seller has another 67mm but it's more expensive but still reasonable for these rare filter. It's listed on the shop's website.

"This filter is designed especially for large format cameras, when using bellows and a wide angle lens. It is used to compensate for the differences in light intensity between image centre and the circumference"

I've been keeping an eye open for one of these for a number of years .
Using mostly 5x4 most of my lenses don't seem to need it .
I'll be using some on 7x5 soon where they one might prove useful , such as with the 90mm super angulon .
Shame I didn't see the ones at £30 , but thanks for the heads up that they still had the other one .
Expensive , but half the price that I've normally seen them at .
Their last one should be on its way to Manchester tomorrow !
Cheers .

With E6 film and a 90mm f6.8 Grandagon on my Wista 45DX you can just notice very slight traces of light fall off at corners, with B&W it's not apparent. If I use the same lens on one of my 7x5 cameras fall off would be more noticeable. This is one reason I bought the second filter.

Glad to here someone found that 3rd Hoya/Tokina Center ND filter, I don't remember seeing them advertised in the past and I think Cambrian Photo may have had them in their store for a few years.

Thanks anyway , if you do spot anymore , let me know .

Bad luck Neil. it may have been because the filters were listed on Ebay as well as their own website although I didn't see that 67mm one. I bought a 72mm & 62mm and luckily had the stepping rings to fit my lenses. The 72mm had a £105 price sicker not there in the ebay photo.

I guess I've been looking for 30 years, I made a mistake not buying a center filter when Robert White were selling off schneiders last stock cheap for around £100, it was around the same time Schneider sold of Xenars and G-Clarons cheap early 2000's.

I'll be keeping my eyes open anyway .
I'm not sure yet if I really need one . I think the 90mm Super Angulon might benefit on 7x5 , but I've yet to find out for sure !
I'll check up on that link you sent though .

I think with 7x5 and a 90mm SA you would need a ND center filter for E6, with B&W you can get away without one that's my experience using 65mm, 75mm and 90mm lenses on 5x4. At the moment I acn't use my 90mm lenses for 7x5, the bellows etc don't compress enough on my Kodak Specialist 2 and there's not enough room for a recessed lens board, however I do have the Dallmeyer 4¼" (108mm) WA that came as part of the Kodak kit but it has no shutter :D

Keep looking . . . . . . .
