Sharpness: At f/2, the center is bitingly sharp—better than the Sony FE 50mm f/1.4 GM. The corners are soft but in a pleasing, painterly way. Stop down to f/2.8, and the entire frame becomes a scalpel. At f/5.6, it out-resolves 61-megapixel sensors.
Bokeh: The 9-blade aperture creates circular, non-distracting out-of-focus highlights. However, there is cat’s eye distortion in the extreme corners wide open. Some call it a flaw. Rafian calls it “character.” rafian at the edge 50 fixed
Chromatic Aberration: Minimal. The lanthanum glass works. Sharpness: At f/2, the center is bitingly sharp—better
Flare & Ghosting: Here is the paradox. The coating is old-school single-layer (not multi-coated). Why? Rafian claims it preserves micro-contrast. The result: When shooting directly into sun or streetlights, you get stunning, dramatic amber ghosts. But for studio work, you will battle veiling flare. You either love this or you return the lens.

A: Absolutely recommended. Any movement at extreme ranges introduces angular error. The fixed mode stabilizes the distance gate, but physical stability is still required. Use a heavy-duty tripod or clamp mount.
