Unique or modified FL 135mm F2.5

  1. Hello everyone.
    I was given this lens because the person had no use for it (got it in an estate lot) and knew I liked cameras. The lens clearly states Canon FL 135mm f2.5. However, it bares no resemblance to any FL lens I have used or ever seen (real or on the web). There is only a functioning aperture switch (8 curved blades). No focus barrel or distance markings. In fact nothing twists or moves except the aperture ring. The whole lens body is smooth. The rear of it is a large threaded mount (approx 58mm diameter and about 10mm worth of thread). Maybe a process lens? Can anyone identify this lens or usage?
    I've included photos of it next to a Takumar M42 for size comparison.
  2. If you look at the picture of an FL 135mm f2.5 lens on the MIR website, that looks like just the front half of a dis-assembled 135mm f2.5 lens.
  3. I have that same lens. It was obviously used for some purpose other than regular shooting on a Canon body. I adapted mine for use on a bellows for close-up work. The only disadvantage is that it is much heavier than the Canon 100/4 FLM bellows lens. The unmodified 135/2.5 Canon FL is one of my favorites. I must have six or seven of them floating around and have used them mostly on Canon F-1 cameras with stop-down metering rather than on FL series bodies. You have to be careful when shooting against the light because the coatings are not as modern as those on the later FD SSC lenses but the lens is very sharp.

    I agree with Steve. It appears to be a part of a disassembled lens.
