In addition to an older comparison I did:
http://forum.mflenses.com/comparing-super-takumar-55mm-f-2-to-f-1-8-and-others-help-t61328,start,25.html
I decided to do a new comparison with 50mm and 55mm lenses. This time I used an Oly E-PL5. Unfortunately I didn't keep all the same lenses. Comparison is between:
- Rikenon XR 50mm f/2
- SMC Pentax 50mm f/1.4
- Super Takumar 55mm f/1.8
- Micro Nikkor 55mm f/2.8
My conslusions:
Rikenon XR 50/2: Quite some chromatic aberration at the tree branches. Softer image @f/2 than the SMC Pentax. From f/2.8 on, slightly better sharpness and micro contrast than the SMC Pentax (look at contrast of cement vs stones).
SMC Pentax 50/1.4: Soft @f/1.4, but good sharpness and contrast from f/2 on. Least CA of all lenses in the test.
Super Takumar 55/1.8: overall, softer image and more CA than the SMC Pentax 50/1.4. Mechanically, I love this lens.
Micro Nikkor 55/2.8: Lots of CA. Probably not optimized for far distance objects. Very sharp image with very nice micro contrast from f/5.6 on.
Best overall performer in this test IMO is the SMC Pentax. Good at wide aperture (F2), seems to deal better with harsh light (less CA). Nice colors and overall contrast.
Please, feel free to comment. |

Just a thought, was this test genuine, or did your wife find to pointing a your camera at your neighbour's window and you had to come up with an excuse? _________________ https://simonforsterphotographic.co.uk/

Nice job. Were the lenses focussed, or at infinity caspert? |

Near infinity. The Oly camera's allow for very precise focusing however. |

I cannot guarantee that the difference is not caused by a difference in exposure. Even considering the exposure, it seems slightly better IMO (the difference between the stones and cement seems sharper/ more contrasty).

I made sure my wife was outdoors |
