Question on mounting lenses with Seiko shutters

Recommended Posts

Hi,

I'm shopping around for a wide-angle lens and have seen several Fuji

90mm's mounted in Seiko shutters. My question is can I mount these

lenses in a standard lensboard for my camera? If so, which

size 'opening' (#0, #1 etc) would it need? Also, in the ads for these

lenses at KEH it says something like 35MT - does this mean anything

to anyone?

 

Thanks

Curtis, 35MT means that the size of the mounting hole in the lensboard is 35mm in diameter. Check the offerings on the Midwest Photo Exchange website (mpex.com). If you don't see anything that appeals to you, wait until next Friday and call Jim (or E-mail him at jim@mpex.com). He will return from his trip to Japan on Fri. He can get you a good new, or used Fuji f8 90SW, in the newer type Copal 0 shutter for a very reasonable price. Fuji's in Seico shutters are usually older models. See Kerry Thalmann's home page (Thalmann.com-click on contact-Fujinon lenses), before making your final decision.

I had a 90/5.6 SWD in a Seiko #0. Great lens. According to my Calumet shutter tester, the Seiko was more accurate @ speeds of 1/30th & higher than my brand new Copal 0 on my Sironar S as well as the Copal 0's on my lenses acquired used. And it is a few grams lighter, too. Mounts in any lensboard made for Copal 0. But one big problem forced me to sell it-due to the incidence angle of the cable release, the Seiko shutter isn't compatible with the Technika-type recessed lensboards. So if you plan on mounting it in a recessed board of some type to further expand those bellows & really work that big image circle, make sure you have the right to return the lens.

Curtis I would not worry about fitting a seiko shutter. I purchased a fujinon SW 120mm F8 (291mm image circle) in a seiko shutter and it fit prfect in a copal 0 drilled lens board. The shutter is perfect and great deals are to be had on single coated fuji lenses in seiko shutters. I'm not sure which shutter came first the copal or the seiko but I'm almost positive that they were not as stupid as to change sizes from the standard. Dont let something that is not multicoated scare you away or something in a sekio shutter. Fuji lenses are excellent and if doing b&w you will never notice the difference unless shotting into the sun with out a lens shade. I would not trade my seiko shutter for a copal it works great.

It's possible that the Toyo Angled cable release adapter for copal 0 shutter's might be able to work with the Seiko and small recessed boards. I haven't tried it myself. But I do own a Ilex Caltar 90mm in a Seiko shutter and one neat things about this shutter is that it includes a self timer- so if push comes to shove you could use that.

 

One thing Seikos are notorious for however is that the shutter has a powerful spring and quite a bit of kickback. Be sure you are mounting it to a camera with a solid front standard.
