I just picked up a Fujinon T-400mm lens. Serial number is 693434. The lens was purchased used, but looks brand new - there isn't a mark on it, anywhere. Where I'm a bit confused is on the shutter. All of my lenses are modern, with most of them purchased new. They all have new copal shutters in them, where the aperature adjustment is controlled by a small plastic triangular knob on the 'top' of the lens, behind the shutter winder arm.

FUJI Bicycle Serial Number Examples 1971 -1991 S. These five numbers represent the number of frames. Serial Numbers with a Year of Manufacture of 1989 and. Registering Fuji lens: what's the Model Number? - posted in General Discussion: I was trying to register a new lens. You need serial number, not lens name.

This lens has the aperature adjustment knob on the bottom of the lens, and it's made of the same material as the shutter winder knob. The speed ring is plastic, with coarse 'treads'. The shutter is all black.

A friend has a much older version of the same lens - he's had it for 15 years or so (I think). His shutter has a metal speed ring, but has the same bottom-mounted aperature adjustment knob. I've checked out Kerry T's website, and he states that serial numbers for Fujinon lenses are all over the map, with no logical sequencing, so it's pretty difficult to determine age from serial numbers. Anyone have any idea how old this lens is? From looking at the images on Badger Graphic's website, almost all the Fuji lenses seem to be using the same Copal shutter as the one on my 400mm. Are these 'special' Copal shutters made for Fuji? BTW, the image shown on Badger's website is exactly what I have in front of me.

Since the shutter on your Fuji lens has a black speed ring, then it is the most recent variety. For Fuji lenses that didn't change their name (like W to CMW), this is the primary signature of recent Fuji lenses.

The shutters on both Nikon and Fuji lenses differ slightly from generic Copal shutters. My understanding is that the German manufacturers use the generic type, which is also what you would likely receive if you bought just a Copal shutter from a retailer. The differences between the shutters are merely cosmetic, such as slightly different control levels operating the same mechanisms. Somewhere there is a post by S. Maximus Arcade 2.10 Full Serial. Grimes commenting on the difficulties that can cause. For example, the difference in location of the aperture control is easy to do since the level connects to a disk that goes completely around the lens. There are differences in the locations of the screws that hold on the aperture scales -- trivial until you try to move the aperture scale from a unrepairable shutter to a new one.

I find the differences irritating because it makes it more difficult to adjust a lens while observing the ground glass -- if you have both types of lenses, it leads to more fumbling to locate the aperture lever. If you want to get deep into Copal-shutter-ology, take a look at the threads that receive the cable release -- sometimes they are straight and sometimes they are tapered -- the difference is most noticable if you look at the hole on the side of the post opposite the side that receives the cable release. Both styles seem to work just as well, though most would probably consider the tapered threads as better matching the cable release and thus to be higher quality.
