90mm center filter on 6x17

Neverendingroll · Mar 31, 2024

Hello, I'm wondering if there are people that have shot regularly with a 90mm lens on 6x17, and have not used the center filter.

I'm just trying to determine if I should get one or not. I've seen examples of both but would like to hear from people that have actually shot without the center filter while using the 90mm on 6x17 and what they think.

Thanks!

What organ do you want to donate to buy one

I shoot with a 75mm on my 6x17 camera without a centre filter it's sometimes difficult printing, you need very careful exposure.I now have a couple of Hoya centre filters that were remarkably cheap, sold as used they were in fact new but old stock, I paid less than £100 ($120 approx) for both. Pure luck just before Covid..

With a 90mm for B&W on 6x17 with care you may not need one with E6 colour you definitely need one.

I have decided on a small section my small intestine.

Thanks for your reply Ian.

This would be an 82mm?
Try a kidney

Some years ago, early 2000's, Schneider had a clear out of unsold surplus stock, this included the late version Xenars, G Clarons, and Centre filters. Here in the UK they were only available from Robert White. in the US Badger Graphics. The prices were low a real bargain, Schneider Centre filters for just over £100.

Now Centre filters are hard to find at reasonable prices.

I shoot a Fujica G617, fixed 105mm. I've never felt the need to spend the money for a center filter. I even shoot Fujichrome.

There's a significant difference between the coverage of a 105mm and a 90mm, so that means with your 105mm there's no significant light fall off in terms of illumination.

67mm for the lens I'm thinking about.

My kidney has been reserved for a specific camera. It's worth more than a center filter.

Thank you. What sort of things do you usually shoot?

Good point. Thanks Ian.

My guess is that most people don't use CND filters on 90mm lenses -- especially on 4x5" cameras -- and only some do on wider lenses. The need varies depending on the lens, the format used, the f-stop, the subject matter, the film, personal taste, and who knows what else. I've taken some great shots with a 65mm lens on 4x5" that for some strange reason or other didn't benefit at all from a CND filter.

The 6x17 format, since it is not getting as close to the corners of the IC as say a 5x7" (12.7x17.8cm) image, is less likely to benefit from a CND -- with the same lens.

City streets, some landscapes etc. The fixed lens cameras are a bit of a modern take on a banquet camera. As mentioned 90mm is going to have a bit more falloff. The center filters come up from time to time for 200-300 usd, I just never really wanted to fiddle with it. Ektachrome is breathtaking in 6x17.

It's pretty easy to determine if you need/want a CND filter for your lens/format/taste. Just run a simple test:

What would take the kidney leica, alpa wide?
Just wondering
67mm can be pretty reasonable priced

Shen Hao 6x17.

It seems rather hard to find a 67mm center ND but I have seen a couple around.

CND filters with a rear 67mm thread are probably the most common available. Schneider made six different 67mm versions, and Rodenstock three -- not to mentions Heliopan (two), Hoya, Marumi, and others. But it always possible to use a wider CND filter with a step-up ring -- and a simple test.

Understood. I think if I do go the route of getting a CND, I'll try and stick to the one made for the lens.

Was just going to start a new thread on this specific configuration. Thought 'bout Linhof Technorama before realizing Fuji's G617 will do for the very limited use.

As you have not used nor seen a need for a CF on 105 lens, what bugs me a bit is that Fuji did not even talk about CF for the G617, but then with GX617 they did put out CF's for 90 and 105 lenses. So far I have not been able to confirm the 105 for GX617 is optically same as on the fixed G617. Any ideas what happened there?

Also, to all in the know: are center filters made so universally that brand does not matter? I see how any one of them will change light distribution and help with dark corners, probably better than nothing. After all, expensive is always cheaper then the more expensive. But at the same time, would it not be optimal to use one made specifically by same maker?

Short answer, it depends. For a full answer, see: http://www.galerie-photo.com/center-filters-for-large-format-lenses.html
