| This is my go-to lens for all my low light work. Build quality isn't quite up to par with the Pentax Limited line, but I don't have many complaints other than that the manual focusing isn't as smooth as I'd like (not problematic, but not a joy either).
The most important thing to know about this lens is its very weird IQ distribution. Center performance is incredible, considerably sharp even wide open, and simply insane when its stopped down.
The tradeoff for this is particularly poor edge quality, especially at corners. This means you'll be getting distortion and much reduced sharpness even when you stop down a bit.
Even given its shortcomings, its a tremendous value if you're looking for a low light portrait lens. I wouldn't want anything else for shooting concerts and night street shots. |
