Originally posted by Andrew_Oid Do you like this lens more than the 2.2 version? That was your favorite, wasn't it?
Yes, good call, so many favourites! I am a big fan of the Auto-Takumar 55/2.2. It's a different lens in its design (for example, it has more blades) and rendering. It produces more eccentric bokeh and bokeh-bubbles/balls, and a creamy glow to images, especially in strong sunlight. If you're into unusual bokeh - as I am - then it's a more interesting lens than the Super-Takumar 55/1.8. If you want a lens that is sharper and smoother, requiring less post-processing and less contrast boosting, then the Super-Takumar is a better bet.
FWIW, neither lens would make my short-list of "most favourite Takumars" (!) - that list tends to change with the seasons/mood, but would always include the Macro-Takumar 50/4 preset version and the Auto-Takumar 35/2.3.
Here's a recent photo from the Macro-Takumar.....
