Samyang 10mm f/2.8 overview

  • 1Description

The Pentax K mount Samyang 10mm f/2.8 ED AS NCS CS Lens is a prime, manual focus wide-angle lens designed specifically for use with APS-C-sized image sensors. Providing a 35mm-equivalent focal length of 15mm and a broad 109.5° angle of view, this lens is ideally suited for interior, architectural, and landscape photography applications. One extra-low dispersion element and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, a nano crystal anti-reflection coating system (NCS) has been applied to lens elements in order to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.

This lens features a mechanical aperture coupling that permits the use of aperture priority and automated exposure modes, as well as the ability to control the aperture setting with Pentax DSLRs.

Prime wide-angle lens provides a 35mm-equivalent focal length of 15mm, making it ideally suited for indoor, architectural, and landscape subjects.
Fast f/2.8 maximum aperture benefits working in low-light conditions.
Manual focus design permits selective control over focus placement.
One extra-low dispersion element and two aspherical elements reduce chromatic aberrations and distortions in order to produce sharper images.
Nano crystal anti-reflection coating system improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.

    Samyang 10mm f/2.8 reviews

    10mm f/2.8 ED AS NCS CS Lens (Pentax K Mount) is rated 4.8 out of 5 by 5.
    Rated 4 out of 5 by from Samyang 10mm I like this lens a lot as an artistic tool. It is great for interior shots. Good for wide landscape, and adds a creative compositional view of close work. It is manual focus but the pentax lets you know when you have hit your mark. I usually use a tripod with this lens. Works best around F8-F18 for sharpness and even edges. It has a learning curve for best angle of view to approach a subject, as the geometry can vary with tilt. The lens can be very sharp up close. The distortion is minimal for such a wide lens and can be adjusted in photoshop. With the high megapixel count on modern sensors, you can crop for what you would get with a zoom. Being a prime, it has less issues with chromatic aberration than a zoom.

    Rated 5 out of 5 by from One of the best wide angle lenses I got one of the first copies of this lens in Pentax K mount from B&H and I have to confess I am using it as a shift lens on my Olympus m43 cameras with a Kipon shift adapter. In terms of sharpness, this lens beats easily whatever else is out there for m43, including the Olympus 9-18mm and the Panasonic 7-14mm. No color fringing or distortion noticable. It's a little on the heavy side, and I am not sure whether I trust the focusing mechanics. I am always very gentle when using it. But in terms of shear optical performance, this lens is a gem.

    Rated 5 out of 5 by from Holy cow, another home run from Samyang! Just received this on 4/11 for my K3 and glad I didn't wait as B&H is already out of stock a day later! All exaggeration aside, my preliminary day and night shots are fantastic. Vignetting is acceptable at wide open, but stopping to f/7 quickly erases this. I see very minimal, if any, CA across the aperture range. Samyang's UMC and NCS are no gimmick. The bokeh is nice and soft. I still need to put this lens through a full day of shooting, but for now this is a serious bargain and worth every dollar, hence the preliminary 5 star rating. Best of all, this is a rectilinear lens, not a fisheye! There is no heavy pincushion distortion on the borders. Landscapers like me appreciate power poles and buildings that do not bend on the periphery of the image or need post-processing to correct. I didn't expect this to have an aperture ring, but for the Pentax you simply turn this ring to A (auto) and have full electronic aperture control from the camera. The manual focus ring has just enough resistance, but if you're clumsy you could certainly bump this out of focus. I do wish infinity focus was a hard stop, but this is nitpicking as most lenses are the same. The protective lens cover/cap is a bit flimsy, but does stay in place. However, I wonder how well this cover would remain intact if the lens fell just 3 feet? For those who complain this lens needs AF to be worth the price (there's always someone), they need to ask themselves why that truly matters for a prime UWA lens in the first place. Since this lens conveniently went out of stock soon after I purchased it, I added a photo of the item to prove I own it and to add credibility to this review. I am not a Samyang employee, but I do appreciate QUALITY third party lenses and not having to pay premium prices for the Canikons. Samyang really stepped up their game with their 14mm prime, and IMHO they've elevated the bar again with this 10mm.

    Rated 5 out of 5 by from Great piece of glass great for closeups, portrait epic style and landscape... but most important to me... to capture the milky way at night...

    Rated 5 out of 5 by from Great lens for the earth and the sky I bought this for my K-50 because it was designed specifically for APS-C format cameras. Absolutely delighted with how it worked during our recent trip to Grand Teton and Yellowstone National Parks. The depth of field is amazing - when shooting in bright light I set the f-stop to 4 or 5.6 in AV mode and then set the lens using the depth of field markings. The K-50 happily chirped every time, telling me it was in focus. During the evenings for night sky shooting all I had to do was open it wide to f/2.8 and set the focus marking to infinity - I tested that during the day time as well. Perfect pinpoint stars near the center and just a trace of astigmatism at the corners - very good performance. Looking forward to using this beauty during future travels that take us into grand buildings, where the ultra-wide rectilinear performance will really be handy. Should have bought one three years ago.
