An upgraded version of the EF85mm F/1.2L USM, widely deemed the ´gold standard´ for professional portrait work, this lens is the brightest in its class and offers beautiful out-of-focus effects. By virtue of its precisely ground aspherical lens, which adeptly compensates for spherical aberrations and other distortions, this lens displays exquisite detail and high contrast even at f/1.2. And with the incorporation of a floating lens mechanism, aberration fluctuations are substantially reduced at short and medium distance shots to ensure extremely sharp, quality images consistently at all shooting distances. We have also dramatically sped up AF performance in response to requests from professionals. A faster CPU and optimized AF algorithm allow the lens to focus instantaneously for reliable capture of fleeting photo opportunities. This lens is even more pleasant to use for portrait work because of the very shallow depth of field at f/1.2, coupled with full-time manual focusing for fine adjustment.

Furthermore, Canon effectively reduced the flaring and ghosting common with digital cameras by optimizing internal lens placement and coatings. A circular aperture is also used to maximize the wonderful defocusing attributes of the lens at the maximum f/1.2 aperture. All told, this is the one lens that can meet the toughest demands of professional photographers, whether shooting female portraits with a masterful blur effect or natural scenes in natural lighting.

Sigma 18-35mm F1.8 DC HSM | A Lens The first and fastest of its kind Truly a revolutionary product, the Sigma 18-35mm 1.8 DC HSM is the first wide-angle to standard zoom lens to achieve a large aperture of 1.8. Designed specifically for APS-C sized sensors, the Sigma 18-35mm 1.8 translates to 27mm-52.5mm on 35mm camera. Tapping into Sigma’s long history of lens innovations, the 18-35mm 1.8 DC HSM incorporates a wide glass molded aspherical lens with Special Low Dispersion (SLD) glass to compensate for aberrations and curvature at the widest angle. Internal focusing and zooming allows for more usability and functionality. The 18-35mm is ideal for landscapes, portraits, still life, snap shots, casual, and close-ups and the Hyper Sonic Motor (HSM) ensures smooth, fast and accurate autofocusing. The use of Thermally Composite Material (TSC) reduces size and weight but increases the lens durability. Its new Global Vision design works with its compatibility with the Sigma USB dock for further customization. A 9 blade rounded diaphragm also creates beautiful background blur. The Sigma 18-35mm 1.8 DC HSM is a new benchmark in photographic history and a must have for every camera bag. USB Dock Compatibility Sigma has developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus. About Sigma Since 1961, and with the recent introduction of Sigma Global Vision, we have worked toward one single, simple goal: To hold ourselves to the highest standard of design & manufacturing of imaging products. Photography is all we do. And it’s all we’ve done. So you can rest assured that it’s something we know extensively and care deeply about. You have a vision. We’ve made it our mission. Distinguished by a uniquely fast and versatile design, the Sony A-mount Sigma 18-35mm f/1.8 DC HSM is an Art-series zoom, covering wide-angle to normal focal lengths. Separating itself from the pack, this zoom features an exceedingly bright f/1.8 constant maximum aperture, which suits its use in difficult lighting conditions and offers impressive depth of field control throughout the zoom range. The optical design incorporates a series of SLD and aspherical elements, which help to achieve high clarity and sharpness by suppressing various aberrations, color fringing, and distortion. A Super Multi-Layer Coating has also been applied, too, which controls lens flare and ghosting for improved contrast and color accuracy. Balancing the optical merits, this 18-35mm also sports an advanced Hyper Sonic Motor, along with an internal focusing design, to promote fast, quiet, and precise autofocus performance. As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications. Wide-to-normal zoom is designed for APS-C-format Sony A-mount cameras and provides a 27-52.5mm equivalent focal length range. Impressively bright constant f/1.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques. Five Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. Four aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. Integrated HSM (Hyper Sonic Motor), along with an internal focusing system, realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.

Thanks to this construction, your Firefly lens is protected from accidental water splashes, rain, snow, dust and other airborne particles. This makes it the perfect glass for photographers who need to work in all possible conditions. Perfect for night photography Night photography is not only interesting but also highly rewarding – it allows you to easily create eye-catching images, if you have the right lens. The Irix 15mm f/2.4 is an irreplaceable tool for any astrophotographer – its fast aperture of f/2.4, combined with a short focal length allows you to capture spectacular shots of the night sky and the Milky Way. The night is yours! https://www.youtube.com/watch?v=y7WlAe7-4KE Intelligent Lens Design The Irix 15mm f/2.4 lens has a module that allows you to control the lens’ iris directly from the camera, thanks to which popular semi-automatic modes (PASM) and data recording in EXIF format are available. The use of electronics also enable the lens to be equipped with a focus confirmation system – the camera will announce the correct focus setting (either in the form of an icon in the viewfinder or with a sound), every time you set the focus correctly – it’s easy and convenient! It’s worth noting that Irix lenses have the appropriate correction profiles that are pre-loaded and readable by software (such as Adobe Lightroom and Adobe Photoshop), that will make your shooting experience even more enjoyable. A Build You Can Trust It doesn’t matter if you’re traversing the hot sands of the Sahara or the frigid expanse of Antarctica – Irix lenses never back down from any challenge. The sealing system has been designed to protect the inside of the lens from moisture, dust, and sand. Equally important, the lens does not change its dimensions during focus pulling, eliminating the risk of dirt particles getting swept into the internal structure. These properties not only allow you to work in demanding conditions, but also guarantee the cleanliness of the camera’s mirror chamber sensor. https://www.youtube.com/watch?v=CCgg5tHNSeI Optics that guarantee sharp images Creativity, ideas, and effort put into a photograph would be nothing without the right lens. Thanks to many years of experience in optical design, Irix lenses are characterized by their excellent resolution and minimal distortion (2%) and almost no vignetting. The Irix 15mm f/2.4 lens consists of as many as 15 elements arranged in 11 groups: 4 refractive elements, 2 ED elements and 3 aspherical elements. The focusing distance is only 28cm which, in combination with the f/2.4 light and 9 rounded aperture blades, make the lens stand out with extremely smooth bokeh with an amazing perspective. You compose the frame – we will take care of the rest! Creative Tool It doesn’t matter if you are a professional photographer looking for a lens for your next job, or an amateur looking to expand your focal range – the Irix 15mm f/2.4 is a right choice for every landscape photographer! The Irix 15mm f/2.4 lens is an ultra wide-angle lens created for your full frame (35mm) camera, available in Nikon F, Canon EF, and Pentax K mounts. This lens will allow you to open up to a completely new type of photography – thanks to the 110-degree field of view you will be able to capture eye-catching images, and the excellent optical properties will make the image sharp and full of details. One Lens – Two Versions The Irix 15mm f/2.4 comes in two verisons: Firefly and Blackstone. Firefly – Lightweight composite construction, with an embossed rubber focus ring, allowing for smooth and precise focusing. Included with the lens is a soft pouch. Additional Features Click at infinity – enables precise, easy, and quick focusing. During focusing, you will feel the exact moment when your lens sets to infinity, which is extremely useful when shooting in difficult lighting conditions (i.e. at night). Focus Lock – allows you to lock the focus ring in a specific position, which is extremely beneficial when you want to keep a specific focus plane i.e. in astrophotography, or when using the hyperfocal scale. https://www.youtube.com/watch?v=OfG6jysEL-Q 95mm front filter thread – allows you to use screw-in filters such as Irix Edge UV & Protector, Irix Edge Circular Polarizer, Irix Edge ND, and Irix Edge Light Pollution filter and others. Compatible with Irix Edge IFH-100 Filter Holder – allows you to expand your creativity thanks to Gradual Neutral Density filters with different gradients: Soft, Hard and Reverse Rear Gel filter slot – allows the use of Neutral Grey filters mounted on the rear of the lens, which is a unique feature of the Irix 15mm f/2.4 and Irix 11mm f/4.0 lenses. Circular Polariser Adjustment Window – the lens hood is equipped with a sliding window, allowing you to freely rotate the polarizing filter without the risk of getting dirty. Focus Calibration window – due to the specifics of focus detection in DSLR cameras based on phase detection, it may sometimes happen that the lens needs to sync with the camera. Thanks to this special opening, you can easily calibrate the lens at home using basic tools within 5 minutes. Fast, simple and effective! Compatible with filters What makes the Irix 15mm f/2.4 lens unique is the possibility of using both classic 95mm screw-on filters, as well as square filters, thanks to the Irix Edge IFH-100 holder! Every landscape photographer uses filters – they allow a creative approach to photography, which makes them extremely practical. The filters that you can use with the Irix 15mm f/2.4 lens are all 95mm filters, such as the Irix Edge: UV & Protector – protects your lens against damage Circular Polarizer – cuts off unwanted reflections and increase the clarity of the photo Neutral Density – decrease the amount of light reaching the camera sensor, thus allows, for example, creatively to blurs the motion in your photographs. Light Pollution – cuts off the light of cities, making your night photos full of detail without a yellowish haze Irix Edge IFH-100 Filter Holder allows you to expand your camera’s capabilities thanks to Gradual Neutral Density filters with different gradients: Soft, Hard and Reverse. By cutting off part of the light from the brightest part of the image, you can shoot even in the most difficult lighting conditions. This manual-focus Irix 15mm f/2.4 lens has superb optics, easily the equal or better than the larger, older and more expensive Zeiss 15mm f/2.8. This is a full frame (FX) lens, and I'll be reviewing it as such. It works great on DX cameras, too, on which you may make the usual inferences, but you're wasting most of this lens' performance shot on a small frame camera. The Nikon version should work great with every FX digital Nikon. It has a chip that should let it work in all metering modes and in all P, S, A, and M exposure modes, just like Nikon's AI-P manual-focus lenses. Wow! Even shot wide-open at f/2.4, it's ultra sharp and contrasty at every focus distance. This lens, like most major-brand lenses introduced since 2010, is ultra sharp. It may be the sharpest fixed ultra-ultrawide lens I've ever tested. It's ultrasharp and contrasty and devoid of spherical aberration and lateral color throughout the whole image even wide-open at f/2.4. The only slight imperfection is that it is slightly softer in the last few millimeters of the full-frame corners at f/2.4, but even there it becomes ultrasharp as soon as stopped down a little. It's so sharp and contrasty that it can incite aliasing on a 50 MP Canon 5DSR, even shot wide-open! More good news is even though it has a rounded diaphragm, the Irix 15mm can make 18-pointed sunstars on brilliant points of light at the smaller apertures. Overall This Irix 15mm has optics as good or better optically than any of expensive lenses and takes normal filters, which most of the other lenses do not. This is a great 15mm lens at a bargain price and much nicer than anything else I've ever seen out of Korea. If you're in the market for a fixed 15mm ultra ultrawide, this is probably your best buy. kenrockwell.com About us Swiss precision and Korean ingenious solutions make a powerful mix.
