|Takumar 85/1.8||FA 77/1.8 Limited|
|Original Photos (Downsized)|
|Colour Corrected (Downsized)|
The photos are yellow/orange casted as what *ist DS sometimes tends to be for its AWB and tendency. I still like the colour response of the Takumar more nevertheless, no matter for the original picture that has the cast or the post processed and colour corrected one. The FA77 is sharper (comparatively the Takumar is softer) and more contrasty, though, but whether one likes it or not would be subjective.
