  1. Weight and size: 425 g and 67 × 83 mm are Wikipedia's for the X lens; m42lens.com gives the M42 lens 432 g, 80 × 66 mm; IndianaDinos weighed his M42 lens at 432 g; allphotolenses says 425 g. Wikipedia's figures are used at family level. mountlens.com's 280 g, 83 mm and 49 mm for this lens are the f/3.5's numbers and are not used.
  2. Six blades on m42lens.com, allphotolenses and IndianaDinos; no Fuji document consulted gives the count for this lens.
  3. Dates: no Fuji document read lists the f/2.5 before the AZ-1 manual, and the ST801 manual's accessory list omits it while listing the f/3.5, the 100 and the 200. The lens therefore arrived between late 1972 and 1978, and 1978 is the earliest year it can be shown in print. 1980 as the last M42 year is japb's figure for the whole line.
  4. No launch price was found.
How to tell them apart (expand)
  • The fast 135 in a line that also had an f/3.5 and, in X bayonet, a Fujinar f/2.8: 58 mm filter, over 400 g, against the f/3.5's 49 mm and under 300 g
  • Two engravings only: EBC FUJINON·T (M42, tab) and EBC X-FUJINON·T … DM (bayonet); no single-coated version is recorded

EBC Fujinon-T 135mm f/2.5, multicoated, Fujica M42 with the metering tab:

  • EBC FUJINON·T engraved on the name ring, the EBC in green; black aperture ring, rubber focusing grip, 58 mm filter against the 49 mm of the f/3.5
  • A tab on the back of the aperture ring for the ST801/ST901/AZ-1 open-aperture meter; IndianaDinos ground his off with a Dremel to fit a Pentax body, and the mflenses thread calls it 'a metal tang … that must be filed off for standard adapters'
  • Non-rotating front, about 210° of focus throw from infinity to 1.5 m (IndianaDinos); the hood and the cap share the same thread, so only one fits at a time (SonicScot)
  • m42lens.com: 432 g, 80 mm long, 66 mm across, 6 blades, 150 cm

EBC X-Fujinon-T 135mm f/2.5 DM, Fujica X bayonet:

  • Fujica X bayonet with the DM signal pin, keying lug and orange mark; X-FUJINON·T … DM on the name ring
  • Wikipedia's X-mount table: 5 elements in 4 groups, 18°, f/22, 1.5 m, 67 × 83 mm, 425 g, 58 mm filter
  • Not in the first X-mount brochure, which lists the 100mm f/2.8, 135mm f/3.5 and 200mm f/4.5 DM; the STX-1 manual's lens key has it as no. 48, EBC X-FUJINON T 1:2.5 f=135mm DM

History

The 135mm f/2.5 is the fast telephoto of the Fujinon M42 line and the one that did not exist at the start. The ST701 manual of 1970 lists a 135mm f/3.5 and no f/2.5; the ST801 manual’s accessory list, with EBC lenses throughout, still has only the f/3.5; the Japanese product list carries the f/2.5 only among the EBC open-aperture lenses; and the earliest Fuji document read here that names a 1:2.5 f=135mm is the AZ-1 manual of 1978. So the lens was born multicoated, with the tab, somewhere between late 1972 and 1978, and 1978 above is the year it can be shown in print rather than a launch date. It is a 5-element, 4-group lens with a 58 mm filter, around 425–432 g, 6 blades and 1.5 m close focus.

There are two versions. The M42 lens reads EBC FUJINON·T, has the black aperture ring and rubber grip of the post-1972 line, and carries the small tab on the back of the aperture ring that couples the ST801, ST901 and AZ-1 meters at full aperture. From 1979 the same optic went into the X bayonet as the EBC X-Fujinon-T 135mm f/2.5 DM, though not at once: the launch brochure’s table has the 100mm f/2.8, the 135mm f/3.5 and the 200mm f/4.5 DM and no f/2.5, while the STX-1 manual’s lens key does list it. Wikipedia’s X table gives it 425 g and 67 × 83 mm; the element count, close focus and filter match the M42 lens and no source says the glass changed.

Reviewers agree it is sharp wide open and disagree about what that is worth. IndianaDinos found “unbelievable sharpness and color rendering” at f/2.5 straight off the camera and the subject popping into focus, with CA on hard edges the one fault; the mflenses thread calls it one of the best at its length and singles out the coating; in the Flickr M42 Fujinon group it beats the SMC Takumar 135mm f/2.5 and out-contrasts the 100mm f/2.8. The dissent is Nora Inukim II’s side-by-side with the f/3.5: equal sharpness wide open but obvious blue fringing on the f/2.5, and from f/4 on the cheaper f/3.5 is the better lens at every stop. Prices reflect the reputation; the mflenses posters put a good one at £120 and up, and it is one of the scarcer M42 Fujinons.

Buying one: the lens is M42 screw-thread and works on any M42 body, but its coupling tab can foul some non-Fujica bodies and adapters so that the lens will not screw home and loses infinity; the tab is often found filed or ground off, which is harmless to the optics but permanent, and most mirrorless adapters clear it untouched. Other makers’ M42 lenses with wide flanges can foul the Fujica bodies in turn. Check the six blades for oil and the front group for the haze common to lenses of this age. The hood and cap share one thread. The X lens goes only to the AX and STX bodies, made for six years, or to a mirrorless camera through an adapter with an aperture control ring; the 43.5 mm flange means no DSLR without corrective glass. No launch price was found in any source read.
