3. Creative Use
The 90mm roughly corresponds to a slight portrait telephoto on 35mm format and delivers a soft, slightly flattering look at wide open aperture (T2.8) with measurable barrel distortion – visible on horizon lines at the edge of the frame. The SMC multi-coating suppresses stray light compared to uncoated vintage glass, but produces spherical spots and veiling flares in blue, purple, and red under harsh backlight. This makes it useful for situations where controllable but not excessive flare character is desired. It appears in the indie scene when a set of rehoused medium format Pentax lenses is assembled – more affordable to acquire than dedicated cine glass, with recognizable rendering.

News
In the analog photography community, SMC Pentax 6×7 lenses continue to be very popular. Photographers particularly appreciate the SMC Macro-Takumar 135mm f4 for portraits and the SMC 55mm f4 as a standard focal length. Experts recommend the late Pentax 67 versions when buying for optimal value for money compared to the early Asahi Pentax 6×7 and the newer 67II models.
