Cosina/Pentax/Phoenix/Promaster 1:1 Matched Macro adapter

2008-06-23
On a totally non related used lens purchase, I got this 1:1 Matched Macro adapter in 49mm filter thread and I put it on my FA 50 mm f/1.4 and tried it out one morning

And it works quite well with FA 50 mm f/1.4 in bokeh, color and sharpness. The DOF range becomes very thin and it makes focusing a bit difficult but the AF is working like before. I am surprised with the result.

Flower with FA 50 f/1.4 + Cosina 100mm f/3.5 Macro
Flower with FA 50 f/1.4 + Cosina 100mm f/3.5 MacroImpressions:
  • Adapter allows the FA 50 f/1.4 to auto meter and auto focus like before, which is the nicest thing to use with a fast prime.
  • DOF is narrower once mounted but the AF in FA 50 f/1.4 along with trap focus works as usual
  • Magnification goes from 1:6 to 1:3 after with the adapter mounted
  • Adapter is like a UV filter to add in front of the lens, extremely portable to bring along
  • Very convenient to use as compared to extension tubes or 2x macro adapter that fits in between camera body and lens
  • CA and purple fringes are noted in wide open aperture, but there seems minimal light loss if any. I manage to use the adapter in wide open aperture with the 50mm prime

Where to buy
  • Thanks to CLM in PF for the link. It only cost $20, it is well worth the cost. It is to be discussed if the Promaster is the same as the Cosina adapter that I use

  • Part number PL1001
