About Sigma 30mm F/1.4

Fully compatible with all Pentax Digital SLR cameras, this large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras. Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration.

Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results.

From 40cm (15.7") minimum focusing distance to infinity, this lens creates very sharp images with high contrast.

The HSM models provide quiet high-speed auto-focus shooting, as well as full-time manual focus. Large Maximum Aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.

Please Note:
Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.

There's magic in this glass

One of the reasons I bought a Pentax DSLR is so I could shoot fast primes that would be image stabilized. So essentially, I bought into the Pentax brand so I could use lenses like this. And the lens has not disappointed. It was my first lens besides the kit lens. And what an upgrade it was.

One of the reasons I bought a Pentax DSLR is so I could shoot fast primes that would be image stabilized. So essentially, I bought into the Pentax brand so I could use lenses like this. And the lens has not disappointed. It was my first lens besides the kit lens. And what an upgrade it was. It's great at a party because you can take indoor photos without using flash, allowing you to take more candid photos. And the wide aperture makes for great out of focus backgrounds for portraits. Pros: Center is sharp even wide open at f/1.4 Very fast lens, excellent for natural light photos Fantastic for portraits Cons: slight barrel distortion somewhat heavy corner sharpness is not great, even stopped down. I realize this lens costs about as much as my K-2000 camera body, but it really transforms what the camera can do.

Killer lens!

By

from Hendersonville  -  Photo Enthusiast

You need to have this in your bag! I bought this lens for a few main reasons. I wanted a really fast aperture for low-light conditions and a prime lens. The Sigma for me has it all. Its sharp, crisp and extremely quiet. Auto focus at f1.4 for me was a challenge at first. the more you use it the easier it becomes.

So far so good

By

from Iowa City  -  Photo Enthusiast

I've had this lens for about two weeks. Not a lot of time to develope an opinion but just some initial observations. It's going to be best as a portrait lens, the focus is sharp and accurate when the subject is close (say 2-12 feet). I think the focus speed is good, but not as good as say my Nikon 17-55 or some other Nikon AF-S lenses. The biggest drawback or deficiency seems to be focusing on subjects that are 15-35 feet away. Maybe since the angle is wide, faces are small at that distance but for whatever reason it is consistently out of focus at those distances. AF tracking is not super fast and responsive as say a Nikkor AF-S lens. On the plus side a close subject is always tack sharp, the contrast is high and the colors are vibrant and crisp. I don't know if it will be a good landscape lens given that it does not seem to focus well at distant subjects. OTOH, it is sharp (when its in focus) and it renders colors and contrasts well. So if you're shooting on a tripod and have time to manual focus, maybe it will be a good landscape lens. The construction seems rugged and tough. Overall I think the lens is a good bargain.

Out-of-this-World Performance

By

from Newtown, PA  -  Pro Photographer

I paired this lens with my D7100, and when I look at the results, I think I'm shooting with a medium-format digital. I couldn't ask for better color, sharpness, autofocus, build quality - you name it. In the week I've owned, it, I've used it for nature, landscape and city walkabouts both day and night. It has the perfect focal length for all kinds of general photography in the DX format. And the 1.4 speed opens up great possibilities for low-light and subject isolation.

Great prime for Canon APS-C

By

from Madison,WI  -  Photo Enthusiast

Solid Image quality, and a much needed focal length for APS-C sensors. Focuses pretty quick, but not as quick as canon's USM. Great build quality. Highly recommended as a first prime to go with a standard Zoom. I use this alongside my Canon 15-85USM for low light situations, artsy bokeh up close, or when I want to carry around something a little lighter. Highly recommended.

GREAT LENS

By

from Houston, TX  -  Photo Enthusiast

Great for indoor portraits and landscapes as well. Great bokeh. Some problems with consistency in autofocus, but a solid B+ in my book (I've owned/rented quite a few prime lenses and this is based on a price/performance "ratio").

Superb Quality

By

from Las Vegas  -  Photo Enthusiast

I have a Sony Alpha 700 that I bought with a Tamron 18-250mm F3.5 lens, and I wanted a fast lens that could double for portraits as well as scenery. The Sigma 30mm F1.4 lens fits that purpose very well. It produces very sharp images in limited light situations. While the Tamron images at 30mm are fine at F4.0, they are not quite as sharp as the Sigma at that same setting. Conversely, and surprisingly, the Tamron lens appears to have a bit of an edge when both are stopped down to F16. I can only guess that my automatic spot focus setting may not have been exactly on each time. I blew up the pictures and attached them so you can judge for yourself. For wide angle photography, I am very happy to use the Sigma lens in a stitched panorama mode, so even its lack of wide angle is acceptable to me. I suspect I'll use the Sigma as my primary lens and only switch to the Tamron (zoom) lens when I can't get close to my subject.

Fast and normal

By

from So Cal  -  Photo Enthusiast

Although this is no tiny Pentax Limited pancake, it is not unwieldy. On the APS-C "cropped" format, 30mm is about a "normal" angle of view. For me, it is better than the 50/1.4 I had before. And, the focal length fits between the 21 and 40 I already have. Wide open is a bit soft as you would expect, and the thin DOF makes critical focusing a bit problematic. Still, I'm happy to have it though at the regular price I would be hesitant to get it unless I had a real need for it, which I don't.

No HSM for Pentax

By

from Long Beach  -  Photo Enthusiast

The Pentax version has no HSM. Still, it focuses pretty fast, and the noise is no worse than other lenses.

Questions about this item:

Shopper  Does the Pentax model of this lens actually come without the HSM? I've read elsewhere that this is the case.
Andrew R  This lens in Pentax mount does not have a motor of any sort, it relies on a motor in the camera body for autofocus.
