Sigma 14mm F1.8 DG HSM Art Lens Features and Benefits:

> Sharp, rich image quality

  • Minimized chromatic aberrations: Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help reduce transverse chromatic aberration, which tends to be noticeable in shots taken with ultra wide-angle lenses. The result is outstanding image quality from the center of the image to the edges.
  • Distinctive bokeh effect: Even at the 14mm ultra wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a pleasingly softened background. It’s the unique mode of expression that only a large-diameter lens can deliver.
  • Minimized distortion: Serving as the front lens element, the large 80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

> Offers full-frame coverage

Sigma 24-70mm F2.8 DG HSM OS Art Lens Features and Benefits:

> Superior optical performance

Sigma announces 14mm F1.8, 24-70mm F2.8 and 135mm F1.8 Art lenses

21 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_7013646430″,”galleryId”:”7013646430″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Sigma has released a trio of its high-end ‘Art’ lenses: two primes and one zoom. All three are designed for full-frame Canon, Nikon and Sigma bodies.

The first is the ultra-wide 14mm F1.8 DG HSM, which Sigma claims is the ‘world’s first and only F1.8 ultra-wide-angle lens.’  The lens has 16 elements, three of which are FLD (low dispersion) and four are SLD (super-low-dispersion). It also has a large (80mm) aspherical front element to reduce distortion and ‘deliver outstanding image quality from the center to the edges.’ The 14mm F1.8 has 9 rounded aperture blades, a minimum focus distance of 27cm/11in and a ring-type ultrasonic (HSM) focus motor.

Next up is the Sigma 24-70mm F2.8 DG OS HSM Art. This lens features three SLD and four aspherical, nine rounded aperture blades and optical image stabilization. The lens is weather-sealed and made of a combination of metal and ‘thermally stable composite’ material. The minimum focus distance of the 24-70 is 37cm/1.5in and it uses 82mm filters.

Last, but certainly not least, is the 135mm F1.8 DG HSM telephoto prime. Sigma says that this lens ‘offers the […] resolution required for 50MP or higher ultra-high-megapixel DSLRs.’ It has a hypersonic (ring-type ultrasonic) focus motor that delivers fast (and ‘exceptionally stable’) focus speeds, while an acceleration sensor ‘detects the orientation of the lens’ so the AF system can respond to ‘varying loads on the focusing group due to gravity.’

The lens has 9 rounded aperture blades, dust and splashproof construction, and a weight of 1130g/40.2oz.

Pricing and availability for all three lenses will be announced at a date to be determined.

Press Releases:

SIGMA 14mm F1.8 DG HSM
Introducing the world’s first and only* F1.8 ultra-wide-angle lens

A true high-speed lens that delivers a new dimension of visual experience

  1. 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience
  2. Seventh 35mm full-frame prime lens to join the Art line
  3. Other features 

A true high-speed lens that delivers a new dimension of visual experience

In taking photographs of starry skies or other celestial scenes at night, or of the seashore with a wide perspective, a large-diameter lens is a strong ally, since it allows the capture of a moving subject by adjusting shutter speed without relying on ISO sensitivity. With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, F2 barrier-breaking F1.8, the SIGMA 14mm F1.8 DG HSM | Art is the true high-speed ultra-wide-angle lens for which so many photographers have been waiting. Although some zoom lenses are available that can cover 14mm, the large diameter delivering F1.8 brightness is a singular advantage. Going beyond fast shutter speed, this lens can capture a swarm of fireflies with crystal clarity, a beautiful bokeh effect, and outstanding control of light streaking.

?Key features?

  1. 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience

By leveraging its extreme angle of view and the dramatic perspective this creates, an ultra-wide-angle lens can get up close and personal with a subject while at the same time taking in a vast background—an example of photography going beyond normal human vision.

SIGMA 14mm F1.8 DG HSM | Art combines the extremely deep depth of field that comes from an ultra-wide angle of view with the extremely shallow depth of field that comes from F1.8 brightness. The result is a sharply captured subject set against a vast background dramatically blurred with a beautiful bokeh effect. It is a highly impressive mode of photographic expression that until now simply has not existed.

  • Minimized chromatic aberrations

Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help minimize transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. The result is outstanding image quality from the center of the image to the edges.

  • Featuring a large-diameter aspherical lens element

The SIGMA 12-24mmF4 DG HSM | Art was the first SIGMA lens to feature a large ?80mm aspherical lens element. Building on the expertise derived from this success, the new lens features a large ?80mm precision-molded glass aspherical lens as its front element. This technology has made possible the 14mm F1.8 specification—the first of its kind.

  • Minimized distortion

Serving as the front lens element, the large ?80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

  • Distinctive bokeh effect

Even at the 14mm ultra-wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. It’s the unique mode of expression that only a large-diameter lens can deliver. 

  1. Seventh 35mm full-frame prime lens to join the Art line

Launched in 2012, the SIGMA 35mm F1.4 DG HSM | Art was the first lens in the Art line.

This all-new 24-70mm F2.8 lens from SIGMA delivers the performance and functionality that help pros succeed in news, nature, and many other fields of photography.

?Key features?

  1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital cameras 
  • Outstanding optical performance

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimize optical aberrations. To ensure outstanding image quality from the center to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control, The optical system also minimizes distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

  • A 24-70mm F2.8 lens that meets the high standards of the Art line

SIGMA has continuously pioneered 24-70mm F2.8 lenses that are a step ahead of the times. The first model of this specification, SIGMA 24-70mm F2.8 EX DG ASPHERICAL DF, launched in 2001. Representing the fourth generation of the family, the new SIGMA 24-70mm F2.8 DG OS HSM | Art accomplishes a challenging feat in optical design: incorporating optical stabilizer functionality in a large-diameter standard zoom. By leveraging all of its design and manufacturing expertise, SIGMA has ensured that this new lens fulfills the uncompromising requirements of the Art line for image and build quality.

  • Bokeh that is a cut above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity. 

  • Incorporating advanced aspherical lens processing technology

Aspherical lenses necessitate refined expertise in the design and manufacturing of advanced, high-performance lenses. SIGMA’s first products to feature this technology were the SIGMA 12-24mm F4 DG HSM | Art and SIGMA 14mm F1.8 DG HSM | Art, which both incorporated a large ?80mm aspherical lens as their front lens element. Building on the success of these predecessors, the SIGMA 24-70mm F2.8 DG HSM | Art incorporates an aspherical lens element that helps achieve extremely high resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing technology. Moreover, SIGMA processes the surface of this aspherical lens element with ultra-precise tolerances that are measured in hundredths of a micrometer. This extremely fine surface allows the SIGMA 24-70mm F2.8 DG HSM | Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.

  1. OS functionality and newly designed HSM for success on any shoot

Designed for advanced utility in a wide variety of situations, the optical stabilizer (OS) offers a powerful stabilization effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.

* Based on CIPA’s guideline. Measuring at telephoto end, when it is attached to the camera with 35mm image sensor.

  4. Other features? 

Introducing the ultimate 135mm telephoto featuring top-level performance

135mm telephoto lenses are often categorized as the foundational telephoto, the first one to add to a lens collection. This focal length delivers a strong perspective compression effect, while the large diameter with F1.8 brightness provides a dramatic bokeh effect. By minimizing axial chromatic aberration, the SIGMA 135mm F1.8 DG HSM | Art makes this bokeh effect not only impressive but also beautiful while delivering superb contrast and sharp image quality in every shot. It offers the outstanding resolution required for 50MP or higher ultra-high-megapixel DSLRs. By incorporating its latest innovations in design and optical glass and rethinking every aspect of the lens, SIGMA has ensured outstanding image quality all the way to the edges, establishing the new standard in 135mm telephoto lenses.

With resolution so crystal-clear that individual hairs can be discerned in a portrait, this large-diameter lens also delivers a beautiful bokeh effect, giving photographers everything they need. It is ideal for close-ups and full-body shots, with subjects standing out against a pleasantly blurred background. In addition to standard portraits, including bridal shots, this lens is a top performer for live events, with its super-fast autofocus capturing subjects with ease.

?Key features?

  1. The ultimate 135mm telephoto designed to prioritize optical performance
  • Image quality optimal for ultra-high-megapixel DSLRs

To deliver the ultra-high resolution that brings the best out of 50MP or higher ultra-high-megapixel DSLRs, the focus mechanism features SIGMA’s floating system. No matter what the distance from the subject, this lens offers top performance from the center to the edges of the image. By minimizing distortion as well, the lens delivers impeccable image quality—no need for digital adjustment during image processing.

  • Ideal for portraits requiring a dramatic bokeh effect

The 135mm focal length delivers a stunning compression effect: even fairly close to the subject, the telephoto ring allows the photographer to establish a variety of dramatic perspectives. The compression effect truly shines in both close-ups and full-length portraits, making composition easy. Moreover, the large diameter with F1.8 brightness makes possible a body shot with an impressive bokeh background. In sum, this lens puts a full menu of compositional options at the photographer’s fingertips.

  1. Fast and nimble autofocus photography

The large hypersonic motor (HSM) offers two benefits. It delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. The acceleration sensor detects the orientation of the lens, allowing the autofocus system to respond to varying loads on the focusing group due to gravity. Along with the optimized AF algorithm, these features deliver fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.

Samyang adds 14mm and 35mm lenses to Xeen cinema system

06 Feb
The 14mm T3.1 Samyang Xeen lens

Korean lens manufacturer Samyang has added two new wide angle lenses to its Xeen series of full-frame video lenses. The new focal lengths are 14mm and 35mm, and while the 35mm conforms to the family-standard maximum aperture of T1.5 the 14mm opens only to T3.1. The Xeen system now contains a total of five lenses as these two join the existing 24mm, 50mm and 85mm.

All the lenses are manual focus only, and feature focus and aperture gear rings in identical positions so that they can be switched quickly in and out of the same rig. Filter rings also match, and users have a choice of metric or imperial focus scales. The lenses come with interchangeable mounts, and adapters are available for Canon EF, Nikon F, Sony E, PL and Micro Four Thirds bodies.

The 35mm T1.5 Samyang Xeen lens

Samyang is proud of the way its lenses render out-of-focus highlights, and the new 35mm complements the existing lenses with its 11-blade diaphragm. The wider lens uses a 9-bladed iris.

The lenses should be on sale by March at a cost of £1599.

For more information visit the Samyang Xeen website. 


Press Release:

Two more XEEN Lenses announced by Samyang to complete a Perfect Five-Lens-Set

SEOUL, February 5th, 2016 –Global optics brand, Samyang Optics, has announced the release of 2 new lenses: XEEN 14mm T3.1 and 35mm T1.5. These two lenses, along with the existing 24mm T1.5, 50mm T1.5 and 85mm T1.5 lenses, create a perfect balanced five-lens-set for filming video and cinema with the outstanding image quality from resolving power for 4K+ production.

XEEN is a specialized brand in professional video-cine lens launched by Samyang Optics in 2015. The XEEN lenses are designed with Samyang Optics’ know-how and have outstanding optical performance for 4K+ with the X-Coating Technology, ensuring maximum image quality to create a cinematic look.

The 24mm x 36mm negative size allows XEEN to not only work with full frame cameras, but also with Super 35, APS-C and APS-H cameras. The lenses are available in five different mounts – PL, EF, F, E, and MFT and two different focus scales – metric and imperial units. Also, the aluminum metal housing is known for its reliability in various shooting conditions.

Most of the XEEN lenses come in a bright T1.5 aperture. The lenses deliver high quality footage with clear contrast and impressive colours, even under less-than-optimal lighting conditions. The large aperture also creates a pleasing bokeh effect for a cinematic look.

“Thanks to the rise of multi-channel networks, the demands for video creation is internationally surging and the expectation of video quality is also increasing,” stated a XEEN official. He continued, “to satisfy the international needs, we have completed the first five lenses which deliver a high-quality cinematic image.” As an answer to the future product plan, he carefully disclosed that two more XEEN lenses will be announced in the second half of the year.

Created to deliver infinite possibilities, XEEN14mm and 35mm lenses will be globally available in early March. The recommended retail price of each lens is £1599.00 inc VAT.

dPS Writer’s Favorite Lens: Rokinon 14mm f2.8

10 Nov

“What do you mean it’s a manual lens?”

That is usually the first response I receive when I tell people about one of the favorite lenses I keep in my bag: The Rokinon 14mm f/2.8. I understand their confusion. I never dreamed that I would succumb to the seeming devolution of using fully manual lenses.

Allow me to attempt to dispel the myth that manual focus/aperture lenses are difficult, and ungainly in the field. In mere months the Rokinon 14mm f/2.8 has quickly became a workhorse of my photo arsenal – let me tell you why. Grab a tissue, because it is a love story.

Lens Logo

When I say that the Rokinon is a fully manual lens, what I mean is that there is no autofocus, and that the aperture must also be selected manually, using an aperture ring. This is a sticking point for most photographers, who have only used fully automated lenses. Personally, I have used fully manual legacy lenses for years, and have come to love the tangible control they require while I’m shooting. I really feel connected to the experience, more than I do when using an autofocusing lens.

Lens Full

I will still admit, however, that a fully manual lens is not always ideal for every situation. So what type of photography suits the Rokinon best? The reason I purchased this lens in the first place was because I needed a fast, wide-angle lens, that can function as a main piece of glass for my astrophotography work. I find myself aiming my camera toward the sky more and more, so I really needed a quality lens that could serve as my go-to for most, if not all, of my nightscapes.

The wide-angle view, and relatively large aperture of f/2.8, makes the Rokinon ready-made for night photography, but of course, it is also a great tool for ultra-wide landscape shots. Some may find the 14mm focal length to be just a little too wide for a general purpose landscape lens, but it is most definitely capable of filling the role.

The most incredible quality about the Rokinon 14mm f/2.8 is just that, its quality. For the price, I can honestly say I have never encountered such a well-made lens, that produces tack sharp results throughout its aperture range. My initial test shots surpassed any expectations I could have hoped for from such a budget lens. Reading comments and testimonials from other users of the lens really left me with a healthy dose of, it’s too good to be true, doubt lingering in my mind.

Lens Element

The quality of the build, and the subsequent image sharpness, are virtually on par with lenses which cost literally ten times as much as the Rokinon. I’m not suggesting that a lens with an average cost of $ 324 will be exactly the same as a lens costing $ 1,300 – but the gap between price and performance is, for lack of a better word, incredible. The aperture ring is comfortable to use, and produces a click at each f/stop, marking that is solidly satisfying.

Something that I really like about the Rokinon is the focusing ring. I has a very long travel when acquiring focus; meaning that adjusting occurs relatively slowly. This allows you to achieve tack sharp focus while shooting with the lens wide open at f/2.8, and makes honing in on stars very easy without over or under focusing.

Sample 2

A common point of discussion concerning the Rokinon, in regard to its suitability for night photography, is the extreme low occurrence of “coma” when imaging the stars. Coma refers to an optical phenomena called “comatic aberration” (not to be confused with chromatic aberration). Coma is the distortion of small points of light when the light rays enter the lens at sharp angles, which makes small points of light, such as stars, appear to look like comets with small tails. Coma is amplified by imperfections in the lens geometry itself, or in the lens elements, and usually gets worse the further you move from the center of the lens. Yet strangely enough, the Rokinon excels in low coma aberrations, even to the point of OUTPERFORMING higher priced lenses of the same focal length and aperture ranges.

The Rokinon 14mm f/2.8 lens is one that I have grown to love in a relatively short time. The majority of my work revolves around landscapes, and shooting at wide-angles, often in low light. The Rokinon fills the requirements of my shooting needs, and then some.

Sample 3

The full manual functionality of the lens could be odd if are not used to shooting that way, but for me I find it in no way slows me down, or hinders the quality of my images – in fact quite the opposite. The build quality, sharpness, low-light performance, and low coma are bundled together at a price that hovers in the $ 320 USD end of the pool.

In my opinion, if you are looking for a great landscape and astrophotography lens, or if you’re just wanting to get creative with wide angles, look no further than the Rokinon 14mm f/2.8.

What you’ve all been waiting for…here are some images shot using the Rokinon 14mm f/2.8! All images shot with a Sony A7r and processed using Adobe Lightroom CC.
