Question: this lens can use for Kr?
Document: This lens works well with my Pentax Kr and K5-II camera bodies. Pictures are clear with limited to no distortion when taking close-up images.
This is an excellent lens for the price. Great IQ! Good focal length to use and work with effectively 50mm, which is what the eye sees.
If you use a Pentax digital camera with a K mount this lens is a must-have unless you can afford the D* grade. I can't and this lens delivers what matters: good images.
As mentioned here, the lens has a plastic body.But the quality of resulting images is very good.I have been able to use the lens to shoot wider-angle city scenes as well as face, portraits, and other closeups.
I was hesitant to buy this lens despite the good reviews as I tend to use my 50mm f1.4 for most of my portraits that I shoot. I decided to try this camera at an outdoor photo shoot, and I am really amazed at the results. The color was good, and it was extremely sharp on f3 with a good depth of field. It isn't as fast as my 50mm, but it is definitely a nice addition to my portrait lenses.
I first started to consider purchasing this lens when I fell in love with an old Super Takumar 35mm f/3.5 lens I received from a friend. I figured that the DA 35mm f/2.4 would be easier for me to use since my only goal was having a 35mm with auto focus. I wasn't just surprised when I received this lens in the mail... I was astonished!
f/22 suffers a bit, but is still acceptable. It's *incredibly* sharp from f/3.5 through f/5.6... nearly to the point where it's TOO sharp. (Did I just say that?) The color rendering is surprisingly similar to the old SuperTak: Beautiful. This lens also handles sun flare very well. All of these factors have made this little 35mm my favorite lens and I use it for work 80% of the time.
Vignetting is almost nonexistent, again easily correctable. CA's are there wide open but at f/4 there gone. No doubt they will appear in high contrast conditions but there are tools to correct this including in the K5 which I use. You will have to know your subject and change your setting on the fly.This lens does not come with a lens hood but I did buy a metal one from Rainbow Imaging for $8.59 (Prime) listed on Amazon. I really recommend this hood.
The free shipping was fast as usually, thanks to Amazon.com!You can read all other reviews for its pros and cons. I'm just telling you why I've picked up this lens.I went to a kid's party about two weeks ago, I took my K-x with the 18-55mm kit lens on it. I set ISO to 1600 (sometimes 3200) auto. I didn't use flash at all. Most of time, the indoor light were sufficient for a decent photo.
I've been very pleased with my choice. I handle my lenses carefully, so I'm not concerned about its non-metal casing. For the price and performance, it's a pleasant little lens that just might stay on your camera longer than you realize.Here's an update to my previous review. Recently, I supplemented my Pentax K5 with the Pentax K-01, which I use when travelling by air or when I need something a little smaller with fewer lenses to carry around.
Answer: Yes, it will fit and work perfectly with the K-r.
