70–150mm · f/4
The Konica Hexanon AR 70-150mm f/4 is a compact, all-metal one-touch zoom from the early 80s, with a built-in lens hood and no length change during zooming. Optically, it offers decent sharpness and contrast for its era, with no visible distortion or vignetting, but sharpness and contrast are slightly inferior to its predecessor, the 65-135mm f/4, and it is prone to stray light. On a high-resolution sensor, it underperforms compared to peers like the Canon nFD and Minolta MD 70-150mm lenses. The rotating front element complicates filter use. It suits collectors or those seeking a compact, rare Konica zoom, but not demanding modern digital use.
