Thread: Compact 420 - 450mm Lens

    Compact 420 - 450mm Lens

    Hello,

    Aside from the 450mm Fujinon C, are there any reasonably lightweight and compact, non-telephoto lenses in this range? This can include non-current offerings.

    TIA

    There are a dizzying number of B&L Protar combinations which might fit the bill. Single elements which are the equivalent or a 420mm lens or a 490mm lens perform surprisingly well when used behind the diaphram and are much less expensive than the Fuji offering. You do need to refocus a little after stopping down since the usually have some focus shift. If you buy a series 7a (two elements, which may or may not match) you can have a very decent shorter focal length plus one or two longer lenses. These are typically mounted (remounted, probably) in Acme No. 3's or No. 4's and originally were most likely in Compur's except for the really old ones.

    As long as we are talking Acme fours, a 16 1/2 inch apo-artar in shutter doesn't doesn't suck even a little bit.

    My $001.5....

    An Acme 4 shutter is kind of large (go to www.skgrimes.com for dimensions of Acme and Ilex shutters) but not as huge as an Acme 5, and the 16-1/2" Apo-Artar shouldn't protrude too far on either side, so I would say it's fairly compact for a lens of that focal length.

    if the Apo Artar in Acme shutter still qualifies as small, then certainly a Nikkor M 9/450mm will also do. The biggest thing here is the shutter, which is a Copal 3. This lens has the advantage that it is relatively easy to find used as compared to the Fujinon.

    The Copal 3 is just too big - any other lenses in a smaller shutter?

    John,

    If the copal 3 is too large for you, then you won't care for an Acme 4 either.

    This should give you some idea of why the Fujinon lens is so popular. And it covers 8X10 too. The Acme shutter will run well for years after a service and it is quite reliable and decently accurate. But it is relatively heavy for its size. On the Protar option there are some single element protars that have smaller diameters and can be mounted in Acme #3 or Copal 1's.

    It may be possible, although I am not positive, to mount a 16 1/2" Artar into a Compur no. 2 shutter. This is a custom, and very expensive solution, but may well be the only other option, other than the two suggested above, a single element lens or the Fujinon..
