Samyang T-S 24mm f3.5 ED AS UMC Tilt/Shift lens review


media_1385750024984.png


With their range of movements tilt and shift lenses offered in various focal lengths for 35mm full-frame DSLRs have become indispensable for architecture, interiors, still-life, food and product photography. Before Canon redesigned their film-era 24mm version with an improved optical design and uniquely, adding a user-selectable option of aligning the tilt function with the shift movement, these lenses were quite reasonably priced.

Just four years ago, Canon offered the three focal lengths (24, 45 and 90mm) at £899 each, suggesting that these were marketed a ‘loss leader’, to entice users to switch from Nikon. At that time, with just one 85mm f/2.8D model in the range lacking automatic aperture control, Nikon was lagging behind.

The firm was soon to refresh the 85mm, while adding a 24mm and 45mm each with electronic automatic aperture control (a first for Nikon), identified by the PC-E designation. As with the earlier Canon TS-E models, they lack the option to tilt and shift in the same plane, prompting some users to call these lenses shift and swing. While you can specify the movements to be aligned at the factory when ordering new, or retrospectively via the subsidiary for a fee, it’s not exactly flexible if the user wants to switch back and forth regularly.

While Canon has yet to upgrade the 45 and 90 mm models to include this sought-after feature, the upgraded version, the EF 24mm f/3.5L TS-E now retails at just over £1,700, while the less capable Nikon 24mm f/3.5 D ED PC-E is just shy of £1500.

Third-party offerings are limited to three Schneider Kreuznach models, which start at £2,800 for the 90mm but increase dramatically to £5,400 for the 28mm. Crucially though, these can tilt while shifting, like the new Canon models.

However, ROK based Samyang is the first to offer a accessibly priced 24mm f/3.5 at £950 inc VAT and in a number of mounts, including Sony A and Pentax K, as the usual Nikon and Canon. The manual claims Sony E, Samsung NEX, MFT and even Fujifilm X-mount, but these have yet to be seen. The optical construction is promising with 16 elements in 11 groups, of which two elements uses ED glass and two adopt aspherical surfaces. However, movements are still quite conservative (though similar to rivals) with ±8.5-degrees of tilt, and ±12mm of shift.

As with others in the firm's range, the Samyang lacks autofocus, obviously, and any automatic aperture control. In fact, there are no mechanical or electronic interfaces on the lens mount, so there’s no lens data exchanged (or EXIF data visible in post). The Schneider models are the same, in that respect. Most cameras don't have a problem with stopped down metering but this may be an issue. It's simply all too easy to forget, especially if you have already worked with the Canon and newer Nikon equivalents with their electronic aperture control.

Build quality is good rather than great. The body including the tilt-unit and shift plate is made from an aluminium alloy but the plastic aperture collar seems rather cheap. On a short-term loan, it's impossible to say just how well it stands up to professional use. From a quick look inside the throat of the lens, the rack and pinion teeth seem sturdy, but the same can be also said of the Canon models and they're known to break (usually when trying to make an adjustment while the mechanism is locked).

The lens has no hood, which is a pity as the front element is both barely recessed and heavily convex. To its credit it's largely free of flare on the Canon EOS 1 DS MK III I used for testing, but it is highly prone to ghosting. Patches are small but it's worth shielding the lens at all times if shooting even vaguely towards the sun.

media_1385750155533.png
While one of the less visually interesting stitched panoramas taken with the Samyang, this particular image was chosen for the presence of ghosting. It's a fairly common phenomenon with this lens, necessitating effective shielding and just one of a couple of reasons that dictate the use of a tripod pretty much exclusively.


A small depth of field scale is included though this is largely redundant on today's high-res digital bodies. With the relatively short throw of the manual focus collar, especially between infinity and 1m, focus accuracy is critical. My Canon focus screen is usually accurate enough for manual focusing at this maximum aperture but I had a number of poorly focused images when handheld. And, that's despite owning two Canon TSE lenses (one a 24mm) and having experience of using virtually every other model for DSLRs, including the Hasselblad HTS adaptor. I can really only conclude that tethering or focusing by live view (or EVF if you have it) is essential.

As with the Nikon and Canon models, the Samyang adopts knurled controls to adjust the movements and has smaller versions of the same positioned 180 degrees apart on the outer casing to lock them. These are all made of plastic and are quite small. They're also fiddly to use when the movements and their associated controls are 90 degrees apart let alone when the tilt option is aligned with the shift movement.

The much more expensive (and much larger) Schneider models avoid this scenario completely by adopting locking collars and by duplicating markings on the barrel, which may account in some part for the additional price.

Although the slim profile of the Samyang’s controls is a necessity to avoid obstructing each other, it is not the Samyang's only shortcoming. More of an issue is that movements are slack, and that once unlocked the barrel is free to move and more often than not simply drop, due to gravity. This alone makes it almost impossible to use without error when hand-held, something that I do regularly with my own TS-E lenses. Locked down on a tripod it's a different story, but it's an unnecessary complication that's avoided with the Canon and Schneider models. With that proviso, the Samyang is sharp centrally wide-open but optimal performance isn't achieved until stopped down to f/5.6-8. Some slight fringing is visible on high contrast edges if you look carefully but it's negligible and easily removed in post.

For me, personally, the Samyang's inability to reliably hold tilt and shift movements while making adjustments for occasional hand-held use is disappointing. However, if it's to be used exclusively on a tripod, as is often the case, the Samyang can be recommended. It will certainly be attractive to Sony full frame users, where the EVF and focus peaking of the Sony SLT-A99 will be a huge advantage over the OVFs in the current Nikon and Canon models.

Outstanding design, exceptional performance – Canon sets new standards with the EF 300mm f/2.8L IS II USM and EF 400mm f/2.8L IS II USM

United Kingdom, Republic of Ireland; August 2010 – Canon today enhances its premium L-series with the launch of the new EF 300mm f/2.8L IS II USM and EF 400mm f/2.8L IS II USM – two high quality super-telephoto lenses designed to meet the demands of professional photographers. Offering optical excellence and consistently high performance, the new lenses combine super-telephoto focal lengths, fast aperture and outstanding image quality, providing photographers with reliability and exceptional results.

Succeeding the well-respected EF 300mm f/2.8L IS USM and the EF 400mm f/2.8L IS USM, both new models will appeal to nature, wildlife and sports photographers. Each features a completely redesigned optical system and the latest iteration of Canon’s original Image Stabilizer (IS) technology, while an all-new magnesium alloy construction and titanium components ensure the designs are both robust and lightweight. The EF 400mm f/2.8L IS II USM is the lightest lens in its class ( as of August 2010) offering unrivaled mobility due to an incredible 28% reduction in weight (1.5KG) compared to its predecessor, while the EF 300mm f/2.8L IS II USM offers photographers an 8% weight reduction.

Ultra high performance optics
Manufactured using the very best optical components, the new EF 300mm f/2.8L IS II USM and EF 400mm f/2.8L IS II USM mark a significant step forward for Canon’s L-series, which is already renowned for its outstanding quality. Both lenses feature 16 elements in 12 different groups, using high performance fluorite lens elements that correct chromatic aberration to deliver high resolution and high contrast shots of the best possible quality – allowing photographers to capture images rich with edge-to-edge detail.

The optical elements also feature Canon’s latest Super Spectra Coatings, optimised for both the position and type of each lens element. A SubWavelength Structure Coating (SWC), which uses microscopic cone-shaped structures smaller than a wavelength of visible light, reduces ghosting caused by light bouncing back from the imaging sensor. Fluorine coating is also used on the front and rear elements of the lenses, repelling dust and dirt for clearer shots. The coating is also water repellent, keeping the front element free of water marks and smearing by ensuring water runs off the lens quickly.

New, improved IS and rapid AF
Both models feature Canon’s new Image Stabilizer system, providing outstanding results when the photographer is moving around and when capturing moving subjects. A 4-stop advantage offers greater image quality during handheld shooting, allowing users to shoot at speeds up for four times slower than normally required with minimal additional blur. Operation of IS mode 2 has been improved when shooting panning motion and a new third IS mode has been added, assisting users when quickly switching between subjects by activating the IS unit only during exposure.

Both lenses offer a constant f/2.8 aperture, allowing photographers to shoot at faster shutter speeds and capture clear shots of fast-moving subjects. The wide aperture also allows users to creatively isolate their subjects from the background, with a nine-blade circular iris creating dramatic and striking background blur that instantly adds beauty to an image.

Fast, quiet Auto Focusing (AF) is provided by a ring-type USM, new dedicated AF algorithms and a new high-speed CPU, which offer quick and accurate focusing during shooting. Photographers can also utilise full-time manual focusing functionality, which enables the adjustment and fine-tuning of focus even when the AF system is activated, providing even greater control over image capture. A new Power Focus mode aids focusing during video shooting, allowing the photographer to smoothly adjust focus during filming by twisting the focus recall ring.

All-new premium L-series design
Developed in line with Canon’s philosophy for the elite L-series, both the EF 300mm f/2.8L IS II USM and EF 400mm f/2.8L IS II USM boast a refined design that reflects their status as market-leading, benchmark lenses. Both feature a new design layout, with carefully-positioned controls that improve operation in everyday use. The AF stop buttons are now location-adjustable, improving ergonomics by allowing users to custom-select the position of the lens grip, where the AF stop buttons are located.

A choice of dedicated tripod mounts provides added flexibility, allowing photographers to use a long or short foot suitable for monopods or tripods. A new rotational mechanism for the tripod collar also provides a smoother movement when turning the lens from portrait to landscape orientation. In addition, both models feature a new high quality exterior texture, while a new shade of white casing indicates the new advanced design and higher precision that each lens offers. A new Kensington-type wire security lock has also been added, allowing photographers to keep their lenses secure during location-based shoots.

A robust weatherproof design makes both lenses suitable for use in extreme conditions when paired with a weatherproof EOS body.

Complementary, high quality lens extenders
Both new models are compatible with the new set of Canon lens extenders designed for L-series super-telephoto lenses – the Extender EF 1.4x III and Extender EF2x III. Manufactured to complement the new optical systems featured in both lenses, the Extender EF 1.4x III and Extender EF2x III will allow professionals to instantly extend the focal length of either lens by 1.4x or 2x respectively – enabling the capture of high quality, detailed images of subjects that may typically be beyond reach.

Pricing and Availability
The EF 300mm f/2.8L IS II USM is available from December priced £7499.99 / ¤8929.99 RRP inc VAT
The EF 400mm f/2.8L IS II USM is available from December priced £11499.99 / ¤13689.99 RRP inc VAT9.99 R

See everything through different eyes – Canon launches the EF 8-15mm f/4L Fisheye USM zoom lens

United Kingdom, Republic of Ireland, 26 August 2010 – Canon today unveils the world’s first fisheye zoom lens offering both circular and full frame images, thanks to an extreme wide-angle focal range of 8-15mm. Replacing the EF 15mm f/2.8 fisheye, the new EF 8-15mm f/4L Fisheye USM is the latest addition to Canon’s L-series range of professional lenses, providing outstanding image quality, constant aperture throughout the zoom range and a robust design for reliable shooting in challenging weather conditions.

When paired with Canon’s full-frame DSLR bodies, such as the EOS 5D Mark II or the EOS-1Ds Mark III, professional photographers can choose to capture circular or full-frame fisheye images, allowing them to view a scene in a completely new and unique way. This new level of choice provides enhanced creative flexibility when shooting scenes such as the night sky, where the full 180º horizontal and vertical fields of view (FOV) allow every detail to be captured with incredible clarity in one single image.

When used with EOS bodies featuring APS-C or APS-H sensors, the EF 8-15mm f/4L Fisheye USM produces a more traditional, full frame fisheye view. A zoom-lock mechanism on the lens body allows the range to be limited to the focal length that ensures the best possible full-frame view without unsightly vignetting around the edge. ‘C’ and ‘H’ markings can be found next to the zoom operation ring, indicating the wide-angle zoom position where vignette-free shooting is possible with either sensor, allowing photographers to achieve optimum results with any EOS body.

Advanced optics for professional imaging
The EF 8-15mm f/4L Fisheye USM showcases over 70 years of Canon’s optical engineering heritage, boasting 14 lens elements in 11 different groups, including one aspherical and one Ultra-low Dispersion (UD) element to correct chromatic aberration and produce high-quality, high-contrast shots with excellent colour reproduction.

Ghosting and flare caused by strong light sources can be a particular challenge when shooting at such a wide angle, and, in order to counteract these artefacts, all lens elements have been covered with Canon’s Super Spectra Coating. The inner surface of the front element also features Canon’s SubWavelength Structure Coating (SWC), which uses tiny cone-like structures, shorter than the wavelength of visible light on the surface of the lens element, to gradually slow light down until it is at the same speed as it travels through glass, removing the risk of flare occurring before the light reaches the sensor.

To maintain optimum image quality, the front and rear lens elements also feature a Fluorine Coating which actively repels water, dust and dirt, making it easier to clean the lens and leaving it unobstructed by particles.

Fast, accurate focusing and low light performance
The ultra-wide angle zoom of the EF 8-15mm f/4L Fisheye USM offers a fresh take on sporting action or architecture shots, while the constant f/4.0 aperture allows faster shutter speeds to be employed for natural-looking images in low light.

A ring-type ultrasonic motor (USM), provides quick and accurate focusing when shooting and enables a full-time manual focus functionality allowing photographers to adjust the focus of any shot, even when the AF system is activated, for even greater control over image capture and improved creative flexibility.

Built for professional performance
The EF 8-15mm f/4L Fisheye USM features a high-grade physical design that reflects its elite performance. High resistance to both dust and water enables it to be used in a range of challenging situations, and, when used with a professional EOS body, it allows continued shooting in the harshest weather conditions. The external design also features the new exterior texture, for a high quality look and feel indicative of all new L-series models.

High quality accessories
The EF 8-15mm f/4L Fisheye USM is supplied with a dedicated lens cap, lens pouch and a felt-lined lens hood EW-77 for use when using the zoom at the 15mm setting, preventing lens flare.

Pricing and Availability
The EF 8-15mm f/4L Fisheye USM is available from January 2011 priced £1499.99 / ¤1789.99 RRP inc VAT
