Question: Does it work with Pentax K- 30 ?? or Do I need a adapter??
Document: I use this prime lens with my Pentax K-30 camera and I find it very useful for indoors use, although it is quite good outdoors also. My pictures come out beautiful! Bear in mind that this is a 50mm lens if you use it with a full frame camera; in my camera works out as a 75mm lens.
I want to use this review to address a few questions other relative newcomers with conservative budgets might have. I own a K-30 that I bought with the 18-135mm zoom lens, which I like a lot.
Excellent value for the money -&#62; I mean how much better can the DA* 55mm be? $500 better? Maybe so but this fast 50 has earned a very regular spot attached to my K-30. Also use it on my older K-x body.
I have been shooting for about 6 months with this lens attached to a K-30 and the photos are beautiful. I shoot a lot in very low light situations without flash and in full manual mode and have been impressed with its performance. It is a great lens and great value for the money.
After some experimentation, I confirmed for myself that a 50 mm prime is precisely what I needed to take my photography up a notch (and that I'd have to spend more than $30 if I wanted good images).So I got the Pentax DA 50 mm f1.8, and I am happy I did.
I have many lenses - I also have an old Super Takumar 50mm/1.4 to compare this to. Sometimes, though, you need an auto lens - people don't have the patience to wait on you dialing in that manual lens around the dinner table - especially in low light where it's very challenging.Keeper. I'm using this on a Pentax K5ii if that helps. And, I know people get bent out of shape because it's plastic -but at the same it's light as a feather.
However my husband has been borrowing it frequently for his more advanced kit (a Pentax K-5 with a full range of Limited lenses) which he uses for formal occasions and organized shoots. So this lens is seeing a lot of use since we got it, and we couldn't be happier with the results.
It's great to know that Pentax users don't need to spend a lot to get great quality optics. While the plastic no-frills build of this product may seem deceptively cheap, the end product is a lens that will complement any photographer's kit, whether beginner, hobbyist or professional.First, this lens is very light. The all-plastic construction means no extra weight, so carrying this lens around adds no noticeable bulk.
I can't begin to tell you how much you *need* this lens in your collection. If it had cost twice as much, I still would be happy with it. I love the narrow depth of field it provides when shot wide open, but what I really enjoy is how well it performs in low light.In that twilight time after the sun has set but before it gets dark, most of my other lenses require either a flash or a tripod.
I keep shooting handheld with no flash until all light was truly gone, and it kept turning out fantastic results. Of one of the photos I took that evening, a friend said "This looks like a still-frame from a movie! "If you are used to shooting with a zoom (like I am) it will take some mental adjusting. At first I kept reaching for the lens to frame my shot, and then remembered that I would need to physically move.
Answer: Yes it works
