Latest Review Posted | SMC Pentax 24mm F2.8 I have used this lens for about 1 year now - it was time to contribute with a review. I use this lens as a landscape lens only. It would work well for street shooting as well given that it's relatively fast but probably an A 24 would do better on street because of its automation.
Sharpness is not that great at f2.8 - the max aperture is usable but it's probably the weak point of this lens. On top of that the sharpness in the corners is problematic on 35mm format. Given that I use this for landscape where the aperture stays between f5.6-f16, the sharpness is really not an issue for me. As a matter of fact, I have printed some of my best shots at 30x45cm and I feel I could print 60x90cm without reaching the sharpness limit of the lens. If I had to rate sharpness starting from f5.6 it would get a 10 but otherwise just an 8 from me.
Bokeh is nice and rather smooth than nervous
Color rendition seems very natural to me - something very good for landscape
Flare is amazingly well controlled. I was very surprised seeing how well it controls flare for its age. Either you don't see any or if you see it just looks good - well at least it looks good to me. There is a photo below showing a flare that I produced on purpose.
Purple fringing level on digital is low
Built is typical SMC K therefore very good and focusing feel is again, typical and very good
Here are some of my best landscapes, done with this lens:
