Fujinon W 250/6.7 that seems to be a 210

**Steve Goldstein** · 15-Mar-2010, 16:46

My 250 is 38mm measured from the back of the shutter to the rearmost edge of the rear cell. The same measurement on my 210 is 32mm. And, as mentioned before, the 250 requires a 64mm rear cap, the 210 uses a 60mm cap.

I would nicely explain the problem to the seller, providing all measurements and details. They should take it back, the item was clearly defective. Was "buyer protection" available on it? If so you may be able to file a claim if the seller won't refund.

To confuse matters, I have a 210 (Seiko) which has a 64mm dia. rear element and another (Copal) which has a 60mm dia. rear element... I should check the focal lengths against each other.

Update: Yes, they're the same F.L. - so the design appears to have changed between the Seiko (earlier?) and Copal (later?) variants.

Jim - My 250 is in a Copal and has the 64mm rear-cell diameter. Just curious, are the lengths of the cells, as measured from the rear of the shutter, the same?

I have a Fujinon 250mm f/6.7. The front cap is a 67mm snap-on and the back cap is a 62mm snap-on.

It's 32mm - see attached pics.

I did some test shots with the lens today, and photograped a house with several different lenses. By measuring the width of the house in the negatives, I calculated the focal length to be around 215 - 216 mm. (don't have long enough bellows for the 1:1 test) The lens was sharp, about the same as my 6.3 lens. But since I only have a 4x5, I haven't been able to establish the size of the image circle. (or the sharpness towards the edge of the image circle) This lens is intended for a future wholeplate camera. I might keep it, if I the seller will agree to a substantial refund.

Indeed, your rear cell looks a little small and the angle in which the barrel is converging is different.

Gotta love eBay and its surprises. I would not bother to keep this FrankenFuji...

Some measurements on my 250/6.7's
The good one The bad one
Seiko shutter Copal 1, marked 210 f/5.6 Nikon
250 about 240 focal length
70 70 diameter of front cell
64 64 diameter of rear cell
42 40 OD of front threads
42 36 OD of rear threads
79 78.5 Length overall
25 26 front cell height from shutter seat
32.5 33 rear cell height from shutter seat
68 66 front filter thread ID
61 61 rear filter thread ID

The bad one has LOTS of spherical abberation
It might be good for portraits!
These are clearly different lenses, and I think I have the wrong
rear cell for the bad one.
