Summary: I haven't tested it extensively yet, but with the few test photos I shot, I noticed a marked difference in the sharpness/photo quality of the pictures taken with this lens vs my kit 18-55 and 50-200mm lenses. I winced to spend the money but after reading reviews I thought it might be worth it. It's worth it.
Excerpt: certainly a good lens ( barely bigger than a body cap ... so unobtrusive you can live it on camera all the time ) ... a perfect companion for street shooting with the pentax K-01, having used it for about six months, for me, the only real annoyance is the lack of an adeguate hood by design ... a tendency to purple fringing ( easily correctible in software ) in certain conditions, produces images with really fine color tones ...
Pros: tiny,light,fine color rendition,respectably fast and sharp
Summary: I have had this for a while. I must have taken a thousand shots by now. I can admit that this is a superb lens considering its size and price. great center sharpness wide open. gets better as you stop down a little. Makes a lot of noise when focusing in low light. Not much to complain about but, worth noting. You will hear it in your video for sure. love the lens so far.
Summary: I have a lot of good to say about this lens, so let me start by telling you whats bad to just get it out of the way. 1- Purple fringing can be strong but only in significantly high contrast situations (tree branches in the gray sky, white fence with sun hitting it, etc). Also occurs worst (obviously) wide open at f2.8 stops to 4 stops then is gone.
Excerpt: I bought this on a bit of a whim, as it was available new (sans box) for £129. I found it an excellent buy. Autofocus on both the K5 and K30 is fast and accurate. The lens is sharp enough wide open, and very good at 5.6, and nice and even across the frame. Contrast is excellent and the bokeh is smooth. I much prefer the general IQ to the DA-L35mm f2.4 that I used to have. There is a little CA wide open and at 3.5, but stopping down further seems to get rid of this.
Excerpt: This is a very good lens and a bargain for the money. It is very obviously made of plastic but I can't find any faws in its construction and cosmetics. IQ is good, probaly very good, but not great. I say this bacause perhaps a little unfairly, I compared its results with my Petax-F 50mm F1.7, FA 50mm F2.8 Macro and M 55mm F1.8. The 40mm came in last, although the results were more than aceptable.
Pros: Small, light, well built, good IQ
Cons: lens cap, slight roughness when attaching to camera
