Mamiya-Sekor 135mm 1:4.5 TLR Lens Blue Dot

The Mamiya-Sekor 135mm f/4.5 Blue Dot is one of the best-kept secrets in the Mamiya TLR system lineup. Nestled perfectly between the standard 105mm and the longer 180mm, this lens gives you just the right amount of reach for portraits, street photography, and mid-tele work—without feeling too tight or too wide. The Blue Dot edition features a late-generation Seikosha-S shutter that's prized for reliability and smooth operation. Compatible with all Mamiya C-series TLR bodies like the C220, C330, and C330f, it offers that signature Sekor sharpness with a bit of extra compression and creamy background separation.

Condition: Excellent

This lens is in excellent condition with clean and clear optics—no haze, no fungus, no scratches, and only a few particles of insignificant internal dust as typical for its age. The shutter is snappy and accurate across all speeds, and the aperture blades are oil-free and responsive. Cosmetically, it’s in great shape with only minor handling wear. The blue dot on the shutter face indicates this is one of the later and most desirable versions of the lens.

If you’re building out your Mamiya TLR kit and want something a little tighter than the 105mm without jumping all the way to 180mm, the 135mm Blue Dot is an underrated gem worth adding.
