Pros: Always sharp, professional construction, autofocus precision, diaphragm diaphragm diaphragm, light and manageable
Cons: Noisy autofocus, some (slight) chromatic aberration, missing the AF/MF switch on the barrel, "silver" version a bit flashy, front pressure cap
Opinion: Taken used but equal to the new, it turned out to be a great purchase right away. You immediately notice the metal construction and professional-level assembly, which give the impression of an object built to last a long time. Pay attention to the front cap, metal and finished inside with the velvet, but it is on simply pressure, without "clip" fixing, and losing it is not such a remote eventuality. I happened to find him more than once at the bottom of his bag when I pulled out the lens. The sharpness is exemplary at all openings, without decaying even to f/22, to the point of being perhaps too engraved for portraits. Notice some slight aberration up to about f/2.5 on extreme contrasts, but it corrects without problems. The autofocus, once calibrated with the fine adjustment of the camera, is of a precision I dare say "surgical" and discreetly fast, although quite noisy (beware, the ring rotates with autofocus). In quiet environments such as theatres and museums it is better to use it in manual. By the way, the lack of the AF/MF switch on the barrel is a small inconvenience, you have to resort to the stick on the camera. Having found it used, I had to "satisfy" the silver version, which definitely does not go unnoticed. I bought it to replace the giant Sigma 85 mm f/1.4 HSM. This is also a remarkable goal, with quite similar optical features (perhaps with a few extra violet fraying at full opening) but compared to the Pentax it weighs almost three times and is much more cumbersome, even more so with the huge lampshade, while in the Pentax the latter is embedded and removable. A great comfort! Finally, the diameter of the filters is 49 mm (exactly like the 50 mm f/1.8), while in the Sigma it is as much as 77 mm. A view that is absolutely to be had. Rating 10 |
