BH #PE15028CH • MFR #26345
Pentax smc FA 645 150mm f/2.8 IF Lens
Key Features
  • Pentax 645 Mount
  • 35mm-Equivalent Focal Length: 118mm
  • Aperture Range: f/2.8-22
  • Internal Focusing
The smc FA 645 150mm f/2.8 IF Lens from Pentax is a medium format, manual and autofocusing telephoto lens with a 35mm-equivalent focal length of 118mm. Its fairly fast f/2.8 maximum aperture enables effective low-light shooting with pretty shallow depth of field, and helps produce a natural out-of-focus (bokeh) effect for backgrounds. High-refraction and extra-low dispersion glass help minimize chromatic aberrations and allow for sharp imaging performance with high contrast and clarity. The Super Multi Coating also contributes to high sharpness and contrast. An inner focus system is used to minimize lens extension when focusing, allowing for a closer minimum focus distance. A large hood with a PL filter operation window is included to enable the use of a circular polarizing filter while checking the results through the camera's viewfinder.

I have the 3 lenses that were released with the 645Z as a "package" (the lenses made for this camera). I find it difficult some times to take photos of my children as 645Z focus is not quite as fast as my D850, for example. How quickly does this 150 2.8 lens focus in comparison to the 645Z lenses I have? Love the 645Z otherwise.
Asked by: Fred
The D FA 645 55mm f/2.8 AL [IF] SDM AW Lens, HD DA 645 28-45mm f/4.5 ED AW SR Lens and D FA 645 Macro 90mm f/2.8 ED AW SR Lens that were originally offered with the Pentax 645Z body are optimized for said body. The SMC FA 645 150mm f/2.8 IF Lens is an older lens originally optimized for use with the Pentax 645AF film body, thus the autofocus speed would not as fast as those newer lens.
