  • 1Description

The Rokinon 24mm f/1.4 ED AS UMC Wide-Angle Lens for Pentax gives you a wide 84° view when used with a full-frame 35mm camera, or 61.8° when used with an APS-C camera--excellent for landscapes, cramped interiors, street photography and general photography of all kinds. Four low-dispersion (ED) glass elements and two aspheric elements produce sharply defined images with a minimum of flare and ghosting. The lens focuses as close as 9.84" from the lens, giving you outstanding wide-angle close-up views. A multi-layered and anti-reflection UMC coating provides superb light transmission.

    Rokinon 24mm f/1.4 reviews

    24mm f/1.4 ED AS UMC Wide-Angle Lens for Pentax is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Great for astrophotography I bought this for my K 50 for astrophotography and was blown away by the results. My first try, I was able to get crisp pictures of the milky way. With a cropped sensor camera, I was concerned about the focal length since I wanted big landscapes with the stars above, but with a little stitching in photoshop, I was able to get scenes as large as I wanted. A great lens at a great price. Highly recommended for low light pictures.

    Rated 5 out of 5 by from Excellent lens and has a good DOF. After using this for about a month, if I have to summarize this review in one line, this is an excellent lens, feels great holding it, well built and smooth to operate and would recommend it to all looking for a very fast reasonably priced, sharp, wide lens. Having said that, an important thing that you need to keep in mind before you buy this lens is the specific purpose you want to use this lens for. Its very fast (among the fastest lenses at this focal length) but has some softness at the edges of the image. There are several nuances that you need to be aware of about this lens before you can feel comfortable using it. It takes getting used to. I will try and highlight some of them that I have noted. 1. Please note that this is a manual focus lens, what that means that you need to take time to focus your subjects accurately. If you are only used to autofocus, manual focusing can get irritating after a while. Also this lens is very sharp and has a good resolving power so if your focus is off, it will show in the final image. 2. This lens feels solid and heavy and it has long barrel, the focusing ring moves through a large rotation, so if you need to get a fast focus, all I'll say is either prefocus or have patience. Practice manual focusing if you are not used to it. 3. The focusing ring moves beyond the infinity mark (many lenses do) so be careful when focusing distant objects, especially for night time photography, my suggestion is pre focus and put a gaffer tape on the ring to lock it in position. For landscape as well as astrophotography this is a good idea. 4. It shows quite a bit of softness at the edges at f1.4 and some degree of softness at f2.8. but as you dial down the exposure, the sharpness increases edge to edge. I think its most sharp between f8 to f18. 5. It also shows some degree of shadow/vignetting round towards the corners. 6. It gives a small amount of purple fringing for objects near the edges. Good luck with your purchase :-)
