Takumar
I decided to go all retro with my lenses. I went for a walk and took: 28mm 1:3.5 Super_Takumar, 35mm 1:2.3 Auto-Takumar, 55mm 1:1.8 SMC Takumar and the 200mm 1:3.5 Takumar. All of these are manual focus manual exposure lenses that I mounted to my Pentax K-7. It’s hard to define the look of these lenses but they are different than a modern one that is corrected for distortion. Some of the distortion I think actually adds to the look rather than detracting. The 35mm 2.3 has an unusual effect on out of focus areas creating a kind of swirling vortex of blur. The 200mm has pronounced chromatic abaration creating a kind of halo around bright objects. All these effects are what we see when we look at older photographs and there really is no way to re-create them with processing or apps.
