Fujinon-C 600mm F/11.5 Telephoto vs. Long Lens?

[LFLarry]

I am trying to determine if there are telephoto and standard long lens versions of the Fujinon-C 600mm f/11.5 lens?

Are all Fujinon-C 600mm f/11.5 lenses of the standard long lens design, or are some telephoto? If so, is there a way to identify?

Understanding if one lens is a standard long lens or telephoto makes a lot of difference, as noted on the LFP Lens Primer page at https://www.largeformatphotography.info/lenses-primer/


Thanks

All Fujinon-C lenses in all focal lengths are the same four element design. None are telephotos.

There is, however, a separate Fujinon-T series of telephoto lenses and that includes a 600mm f/12 that is a telephoto.

C stands for "Compact", and that it certainly is. It is a relatively flat looking lens in a no.3 Copal shutter, and it has huge coverage, known to have been used even on 20X24 Polaroid cameras, although up to 16X20 would be more realistic with movements. Fuji does make a nice longish 600 tele, but it's only designed for 4x5 or possibly 5X7 coverage. The size and weight of any 600 tele suitable for 8X10 format would be equivalent to a rhinoceros, and as clumsy as a rhinoceros wearing high heels, which pretty much describes the Nikon 600T ED f/9, which requires 95 mm filters and likely a double tripod setup too. I don't know its actual weight in tons.

Do keep in mind that bellows draw (length required for a given focussed distance) on a telephoto will be less than that of an equivalent focal length non tele...and that the bellows length requirements for a non tele begin, on the short end (when focussed on infinity), as roughly the equivalent of a given non-tele's focal length and go longer as focus distance decreases (gets closer).

In other words, if wanting to use a 600mm Fujinon-C on your camera, your bellows had better stretch out to at least 600mm, and preferably significantly beyond this.

Having said the above, I'd personally prefer to use a non-tele lens (no matter the focal length), over a tele lens, assuming my bellows length will acommodate it.

Thank you for clearing that up. I appreciate it.

Some more comparison specs : The Fuji 600C is 65mm long, in no. 3 shutter, and weighs 575g. The Fuji 600T f/12 is 179mm long, in no. 1 shutter, and weighs 1000g. The C version is much more expensive on the used market.

I use a Red Dot Artar 24" (600mm) on 8x10 and 11x14. In a barrel. Even with fairly long arms, it is a stretch to adjust the aperture and look at the GG at the same time! Have fun!

That's why we need gene therapy infusing us with long-armed Orangutan genes!

I would suggest that if you are taking 11 x 14" or bigger negs, you can just ask your butler to do this.
