Mamiya 645 PL Lens Set 

Rebuilt from a clean set of Mamiya 645 Donor Glass, this set features a new designed 14 blade iris, declicked aperture ring, 114mm front with PL Mount and removable speed booster element. With the speed booster element all lenses are improved by increasing them by 1 stop and 0.7x focal length.

For more information read bellow.

PL Mount

Industry standard PL mount makes it easy to adapt to a variety of cameras.*

*Speed booster element may not fit on all PL Mounts depending on their design. OEM Alexa Mini PL Mount and rear filtration mounts will require the removal of speed booster element to mount properly.

Custom 14 Blade Iris

These lenses have been rebuilt with a custom 14 blade iris allowing for smoother and consistent Bokeh even when stopped down.

Removable Speed Booster

Toolless removable speed booster makes it easy to adjust the lenses for your camera’s needs. While speed boosted the lens has 1 stop of increased light and reduces focal length by 0.7x, thus bringing the image circle from 645 medium format down to 46mm Vista Vision Full Frame.

Multi detailed Lens Caps

Each lens has a multi descriptive lens cap with details for when in use with or without speed booster element.

  • 35mm T3.5 (Speed boosted 25mm T2.8)

    45mm T2.9 (Speed boosted 32mm T2.3)

    55mm T2.9 (Speed boosted 39mm T2.3)

    80mm T2 (Speed boosted 57mm T1.6)

    110mm T2.9 (Speed boosted 78mm T2.3)

    150mm T2.9 (Speed boosted 107mm T2.2)

  • The original lenses were designed to cover a film area of 6cm x 4.5cm, this means that the lenses all cover the Alexa 65 sensor and the New Arri Alexa 265 sensor as standard. However, rehousing them with the built-in speed booster still allows the lenses to cover 46mm size sensors such as the Red Raptor VV, and Full Frame sensors including LF Open Gate.

  • I would describe these as a hybrid rehousing, for the front half has a sleeve type housing with added dampeners on the focus ring (that do not affect focusing to affinity) and provide a rigid mounting point for clip on matte boxes. The rear end of the lens has been rebuilt with a new iris, PL Mount, and of course the removable speed booster element. This allows for a affordable but functional lens for cinema use.

  • Original test footage is coming soon but in the meantime offshoot rentals has a fun lens test of the mamiya 645 glass with their own version that were rehoused by TLS Optics

    *Note the Flamingo set we have here was not rehoused by TLS optics but uses the same lenses as the starting point.
