Pentax 12-24mm f/4.0 overview

  • 1Description

The Pentax SMCP-DA 12-24mm f/4 ED AL lens was developed for exclusive use with Pentax digital SLR cameras, and is a compact, lightweight two-times zoom lens that offers an ultra-wide-angle perspective equivalent to 18.5mm to 37mm in the 35mm format.

The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLR cameras to optimize camera performance. This design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Note: Not suitable for 35mm film SLR cameras.

Extra-low Dispersion (ED) glass for superior sharpness and color correction
Two aspherical elements
Responsive "Quick-Shift Focus System" allows instant shift from AF to MF
Internal Focus system makes focusing smoother and faster

    Pentax 12-24mm f/4.0 reviews

    SMCP-DA 12-24mm f/4 ED AL Autofocus Lens is rated 4.6 out of 5 by 32.
    Rated 5 out of 5 by from Criticism? I am not a pro so take this critique for what it is worth. I have only one criticism of this superb lens. When used with the built in flash of my K-5 it casts its shadow in the foreground of the picture commencing at about 18mm and getting progressively worse by 24mm. That I must remove the lens hood when using flash is only to be expected with a lens this wide hence cannot be criticized. It fits nicely over my arm so there is no danger of losing it. I would highly recommend this lens for both indoor and landscape and architectural photography.

    Rated 5 out of 5 by from Great Lens Of all my lenses this is my favorite. It is just great for taking intimate shots of small groups of people at diner parties and other indoor gathereings. It is sharp and even in lowish lighting I can normally get an acceptable shot without resorting to flash (ISO has to be up a bit). The range is just perfect for this type of work and I am happy with the results of the lens. Any faults in the photos are lack of skill rather than this excellent lens. I saw interchangeability as a charactereistic but I am so paranoid about dust that I just have a different body for each lens.

    Rated 4 out of 5 by from Solid Wide Angle Primarily I shoot wide angle in the portrait (vertical) position while backpacking and climbing. I purchased this lens with the Pentax K-7 to replace my aging Zeiss and 10 megapixel system. Pros: This lens performs admirably compared to the Zeiss. The narrow zoom range and excellent image quality really makes this lens comparable to several primes. Small details in the center and corners are excellent. Stopped down, this lens has the capability to outresolve a 15 megapixel sensor (haven't tried bigger sensors). Cons: Yup. This lens is prone to chromatic aberations (purple fringing) at high contrast intersections. For me, this is not a show-stopper. CAs are relatively simple to fix postprocessing if you shoot RAW, and fixed in-camera if you shoot JPEG. The resolution capabilities of this lens far outweigh the CAs. Recommendations: If you need a quality wide angle lens, and do not need anything faster than f/4, this lens is an excellent choice.

    Rated 5 out of 5 by from Excelent, but shoot RAW only! Excelent build, great focus speed and accuracy. Some PF and CA natural in such wides, but fully controllable if shooting RAW or using lens correction utilities with in camera RAW development in K-3 body. Excellent flare control. If a CPL is needed, get a good quality one with thin brass ring, as it may vignette at 12 mm. Only negative thing is size compared to focal length, as it is bigger and longer than all the kit zooms in the 16/18 to 70/85/135 range. Hood is well matched but huge. Doesn't fit in any camera bag without creating space issues.

    Rated 5 out of 5 by from A well thought compromise Huge by Pentax standards, it is well built and both zoom and focus rings feel right after 8 months of use. Quick shift cam mechanism for switching to manual focus works as expected - no-nonsense. The lens does not focus past infinity mark.Image quality is very good at 18mm, good at 24mm, mostly good at 12mm. Resolution would match the 10 MP sensor if not for the significant chromatic aberration, particularly visible in the corners at 12mm. Once corrected however the image is quite usable for large prints, with excellent resolution in the center.This lens has excellent contrast when shooting against light sources even if it exhibits a well defined, flare spot with sun at 15-30 degrees. There still is no haze veiling the image however. Expertise: Advanced amateur Problems Encountered: Significant chromatic aberration with K10D requiring an additional, time consuming step in the workflow. Items I Recommend: FA 35/2

    Rated 5 out of 5 by from Great lens!!! This is an optically superb lens that out-performs its counetrparts with both Canon and Nikon - I've owned them both. Color saturation is excellent and sharpness is great throughout the range. I have used this lens to photograph salt water fishing events and, matched with the K20D, I am totally satisfied

    Rated 5 out of 5 by from Great value for money performance! This lens offers excellent performance vs cost. I use it mainly for landscape, fashion, bands and it is also useful for skate photography. Unfortunately, it has too much distortion at the wide end for architecture. I love the build quality, so far it seems solid and reliable. It has a reassuring weight to it and it looks professional too. I also own a Canon 17-40mm F4L lens and I must say it pleasantly surprised me with its comparable image quality. Only the weather sealing and auto focus leave a little bit wanting when compared to the Canon. But overall an excellent example of a wide angle zoom. Only gripes are a little vignetting with a polariser at the widest setting and some minor colour fringing, but nothing that cannot be fixed in post processing. Recommended to anyone that wants a portable and capable wide angle travel lens.

    Rated 5 out of 5 by from Very good ultra wide lens When looking for a new wide angle lens, I narrowed it down to 3 options: Sigma 10 -20mm Pentax DA 15mm prime and the Pentax-DA 12-24mm As my other 2 digital lenses are both Tamron, I decided that I would really like to own a Pentax for a change. I also read an interesting article that mentioned how nothing quite compares to Pentax glass on a Pentax camera. While the 15mm seemed like a very nice alternative, I thought I might prefer the versatility of a zoom lens. After reading a number of reviews of these 3 lenses, I was convinced that the 12-24 would be the best option for me. I've only had it for about 3 weeks, but so far I am very happy with it. There are many good things about this lens: The image sharpness is outstanding, especially considering that this is a zoom lens; most reviews remark that it rivals that of fixed focal length lenses. For a wide angle lens, lack of visual distortion is very good. It really excels for interior shots, landscapes and street scenes. Focusing is fast compared to my Tamron digital lenses (90mm macro and 18-200mm zoom). Depth of field is very good, even at widest aperture F4, though this is an inherent feature of wide angle lenses. A few cons, but one must bear in mind that most of these would apply to any ultra wide angle lens of this nature, regardless of brand name: The front element is quite vulnerable to scratches; it has a dramatic convex shape and is very prominent. A filter for protection is pretty much a necessity. The 77mm filters are quite expensive, though if you shop around you can find good quality UV filters for a decent price. A lens of this design is quite susceptible to lens flare, especially outdoors. The provided hood does a good job in minimizing this, though it is bulky and a bit least for me, as I never liked using them. Also the lens hood can cause vingetting, particularly at the 12mm end of the zoom range. If you like to shoot wide angle, this is a great lens to have. So far I have not regretted the decision to buy it, and I'm sure to get lots of good use out of it.
