Latest Review Posted | SMC/S-M-C/Super Takumar 50mm F1.4 Super-Multi-Coated Takumar version - 7 elements.
All has been said and more on this (those versions) lens in all past reviews. I just want to add that the centre sharpness is exceptional at all apertures, even at f16.0. Posted are the photos at ISO 100, f5.6, f8.0, f11.0, f16.0 and with no corrections - straight out of the box.
I used a test chart, on a 24" x 36" pegboard, which seems to be fairly accurate with my new K1 mark II and noticed that the centre sharpness may be shown as being as low as 3.6 ln/mm (line pairs per mm). Tweaking the focus in live view in "focus peaking" shows results down to 4.0 (?) lp/mm but I must say 3.6 as seen below is still pretty good being a higher standard for high quality lenses.
Other findings are lower edge sharpness, low edge distortion, minimal CA, low contrast, no light fall-off.
I fully intend to keep on using this lens with my K1.
