Great Lens

Lens seems immune to flare when shooting directly into or near the sun. Macro closeups are excellent, even though this is not a true macro. Bokeh is very pleasing. Auto focus is fast and quiet.

Well built but not without cons.


from Boston, MA  -  Casual Photographer

I had been debating between this lens and DA 21mm f/3.2 for a long time and finally went for the DA21 because of its versatile focal length. However, after I compared these two recently, DA 15mm can certainly deliver better image quality especially in terms of corner resolution and control of PF. The lens cap design somehow discourages me from using is and I have decided to replace it with a protector.

A Wow lens.


from Oracle, Az.  -  Semi-pro Photographer

I've been wanting a wide angle prime lens for some time now so when this one came on sale I jumped on it. Been using it for a week now and am amazed at the lack of flare, sharpness, and contrast it has.


One major reason to buy


from Melbourne, Australia

The real attraction of this lens is the very small size and light weight compared to both zoom and other prime ultra-wide lenses. Image quality is best when stopped down to around f8 and quite acceptable otherwise without being breathtaking. Build quality is excellent and lovely to handle except for the screw-on lens cap which is a real pain and swapping it for a pinch lens cap will save a lot of frustation. Overall, worth buying if size and weight are the major considerations.


Execellent Lens


from Houston, TX

Wow. That about sums it up. Its sharp.


Superb lens


from Swidnica, Poland

Great lens as all limited lenses from Pentax. Ideally I would like to have them all.


Extremely well built, nice built-in hood


from Metro Atlanta

Like all the Pentax Limited lenses this one is incredibly well constructed with all metal parts and a very smooth focus throw. Color saturation is great with good center sharpness throughout its f range and corners comming along after 5.6. The screw-in lens cap is nice for looks but a pain to use in the field. Fortunately a squeeze-style 49mm lens cap works just fine in its place.


Great compact lens


from Auburn, AL  -  Photo Enthusiast

It is a great compact wide angle lens by PENTAX. Metal coating makes it durable and look good. Hardly no distortion, which makes the lens with this size very attractive. Fast focusing and seamless switch between autofocus and manual focus. only one disadvantage is that it is a little bit noisy when autofocusing due to the lack of USM motor.

a bit dissapointed


from Tyngsboro, MA  -  Photo Enthusiast

After reading the stellar reviews about this lens, I decided to buy. However, I was very disappointed with it's performance - ok center sharpness but very soft in the corners at almost every aperture. Terrible CA's (red/blue fringes) on the edges - in not very high-contrast situations either. Distortion was also an issue but I guess you'll get that with a 15MM perspective. Perhaps I just got a bad copy but this was a big letdown... This lens is built like a tank and has a great feel but QC needs to be improved


This lens is so compact it's amazing.


from Brisbane Australia  -  Photo Enthusiast

Great lens for Street Photography and grab shots. The compact size it selling point of this lens for me. Great for Video as it is nice and wide better than most Video recorder lens
