I couldn't try any prime lenses out because there aren't any Pentax dealers in Hawai'i and I don't know anyone I can borrow from, so I pretty much had to do things backward: get a lens and see if it was worth it. I started a few months ago with the similarly-priced DA 35mm f2.4 AL, choosing it over the 50mm f1.8 for reasons that I can't remember now, and lo, it was in fact worth it. That lens has some issues but at its best, the sharpness and clarity compared to the 18-135mm -- which is a really nice lens -- astonished me. It's a different animal, most noticeably at 100% resolution a few stops down.
The 35mm hooked me on prime lenses but it didn't make me any more financially sound, so this lens was the obvious next step. I'm very glad I took it. Like the 35mm, it's quite light but nicely constructed. When I ordered it I also ordered a hood and a UV filter, as I did for the 35mm, because if I'm going to break any glass I would prefer it to be something that doesn't run into three digits to replace. This lens takes a 52mm filter, while the 35 takes a 49mm one. I got B+W filters for both, and collapsible rubber hoods. I recommend this for the peace of mind if nothing else. A good filter won't affect the image and it will protect the lens.Read more ›
First, this lens is very light. The all-plastic construction means no extra weight, so carrying this lens around adds no noticeable bulk. It's also relatively compact for a 50mm lens, especially one that goes as wide as F1.8.
Second, despite the plastic construction, the build tolerances of this lens are very tight. There's no slop anywhere, it just feels well-made. If the Pentax Limited lenses were made of plastic, they'd feel like this.
And finally (or rather, most importantly), the optics in this lens are outstanding. This is a similar lens formula that Pentax has used in previous very successful products, but updated with more advanced coatings to excel on a digital camera. Items in focus are tack sharp, and the bokeh is dreamy both in front of and behind the in-focus subject. Colors are beautifully retained, and scenes are given a pleasantly warm tone. The F1.8 max aperture means this lens is great for low-light photography.
It's not all roses though. There are a few drawbacks to the budget build. This lens does not have any focus scale anywhere. And Pentax's "quick shift" feature that allows you to adjust focus manually after auto-focus is not present on this product. There's no lens hood or case included, either. This is about as no-frills as you can get. But considering the price and the quality of the optics, I guess some sacrifices had to be made.
Also, auto-focus speed can be disappointing.Read more ›
The Sony's plastic mount never gave me a problem, so I don't expect the Pentax to either. Though they are both nearly all plastic in construction, but the Pentax has a higher quality and solid feel to it. As far as chromatic aberrations go, at f1.8 (wide open aperture) both lenses show a little purple fringing which is not bad and easy to correct in photoshop. At f2.0, the Pentax may still has very minimal aberrations, but only in super high contrast situations. By f2.5 they appear to be completely gone. The front lens is recessed enough that in most cases you can get by without a lens hood. The Pentax gives me good sharpness at f1.8 so long as I nail focus of the shallow depth of field correctly. Those people that complain of this lens being soft wide open are probably missing focus. As you stop the aperture down the Pentax just keeps getting sharper and sharper as you approach f4, where it is so sharp it is probably out-resolving my K30's sensor.Read more ›
