From Tamron: September 1, 2016, Saitama, Japan – Tamron Co., Ltd. (President & CEO: Shiro Ajisaka), announces the launch of the SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022). This second generation “G2” lens builds upon the success of the SP 150-600mm F/5-6.3 Di VC USD, which launched in December 2013 and continues to successfully meet photographers’ needs in the ultra-telephotography category.

The new G2 version was developed to provide superior optical performance with today’s high resolution DSLRs and to add improvements to several features including speed and accuracy of AF and VC (Vibration Compensation). Also, several new features have been added: FLEX ZOOM LOCK mechanism, Fluorine Coating and optional tele converters. The new lens delivers outstanding performance and a luxurious, upscale appearance, including a metal lens barrel.

Tamron SP 150-600mm f/5-6.3 Di VC USD G2 Highlights:

Optical design refreshed to achieve even higher performance

Three LD (Low Dispersion) lens elements completely eliminate axial and transverse chromatic aberrations. The design also features upgraded optical construction (21 elements in 13 groups) and leverages improvements in manufacturing technology. As a result, the lens delivers high resolution, improved sharpness and overall better performance.

Tamron’s sophisticated eBAND Coating for eliminating ghosting and flare

eBAND (Extended Bandwidth & Angular-Dependency) Coating is a nano-structured layer deployed on the lens element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher light transmission and significant improvement in anti-reflection characteristics, especially against angulated incident rays. Combined with of BBAR (Broad-Band Anti-Reflection) coatings, flare and ghosting are reduced to imperceptible levels.

MOD reduced to provide optimum tele-macro photography

Tamron’s advanced manufacturing technology has made it possible to reduce the MOD (Minimum Object Distance) to 2.2m (86.6 in), compared to 2.7m for Model A011, and has allowed for the wonders of tele-macro photography.

AF speed is faster and much more responsive with moving subjects

The Model A022 is equipped with a USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved from current model, and it enables accurate high-speed focus even when capturing moving subjects.

When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.

VC performance is now 4.5 stops and offers three modes optimized for different situations

The VC (Vibration Compensation) effectiveness is equivalent to 4.5 stops, based on image stabilization performance levels established by CIPA (Camera & Imaging Products Association) when using in VC MODE 3. Model A022 now has three types of VC modes, and it is possible to choose the optimum VC mode according to the situation for taking a photograph, such as when wishing to pan the camera.

VC MODE 1 is the standard mode that strikes a great balance between the stability of the viewfinder image and the stabilization effects.
VC MODE 2 is exclusively used for panning.
VC MODE 3 prioritises the stabilization of the captured images and forgoes the stabilization of the viewfinder image.

With the optional accessory TAMRON TAP-in ConsoleTM, you can custom the configuration of VC MODE 1. Choose the viewfinder view of either standard or viewfinder image priority.

New FLEX ZOOM LOCK mechanism enables the locking of the zoom ring at any position

FLEX ZOOM LOCK mechanism quickly locks or unlocks the zoom at any position simply by sliding the zoom ring. Photographers can shoot from any angle without the zoom extending unintentionally. Additionally, the conventional Zoom Lock switch prevents unwanted barrel extension during transportation.

Fluorine Coating and the Moisture-Resistant Construction for a more user-friendly lens

The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

Electromagnetic diaphragm system now used also for Nikon-mount lenses

An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses*2. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

The lightweight and easy-to-hold tripod mount that is compatible with an Arca-Swiss style quick release plate

A new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. And because the tripod mount is made of lightweight magnesium, it is much easier to carry.

Compatible with TAMRON TAP-in ConsoleTM, an optional accessory product

The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.

New tele converters developed exclusively for the Tamron lens

Two exclusive tele converters, which perfectly match the optics of the new SP 150-600mm G2 (Model A022), offer 1.4x and 2.0x magnification, and provide a maximum zoom range up to 1200mm on a full-frame camera, and up to 1860mm on an APS-C camera. These new tele converters extend focal length of the master lens, making it possible to take pictures in farther ultra-telephoto ranges.

Based on the rigorous quality standards worthy of the SP series, this new lens is manufactured with thorough attention to details

For the SP series products in particular, Tamron has established rigorous design and quality standards. These standards apply to the optical design, mechanical design and the cosmetic appearance, as well as to such wide-ranging areas as the product’s robustness and improvements in various individual functions. Tamron thoroughly reviews of all of the design and manufacturing processes in order to offer products to customers with ever-higher precision and quality levels.

For the SP 150-600mm G2 (Model A022), the optical design was refreshed, mechanical parts were improved and a new exterior design was adopted. To maximize the optical performance intrinsic to this product, Tamron improved the accuracy of component parts and increasing the precision of the overall zooming mechanism.

Design Concept

The new design adopted for the four SP series lenses already on the market is essentially the fusion of engineering and style, the pursuit of functional beauty and craftsmanship achieved by giving meticulous attention to minute details. Using metal as the exterior material creates a high-grade design based on the concept that emphasizes “Human Touch” characteristics, and significantly improves user-friendliness. The SP models feature a novel design for the switches, easy-to-read characters, an enlarged window over the distance scale and the adoption of organic forms easy for the photographer’s fingers to hold onto.

This design philosophy—the pursuit of functional beauty with a “Human Touch”—is applied even to the most minute details of the new SP 150-600mm G2 ultra-telephoto zoom. By using metal for the exterior material and adding new functions such as the FLEX ZOOM LOCK mechanism, the Model A022 achieves a size and weight that makes comfortable handheld shooting possible, with a slim and stylish appearance design to top it all off.

During the shooting of the Takumar I caught some specular reflections. I recently built an automatic indoor bird bath for my parrot and it's got a little lightshow that goes off every time it turns on. Those lights showed up in the test chart without me noticing - and I'm way too lazy to reshoot. :D

These were all done on the 1m chart at ISO 100, with AE turned on. WB was set to the chart's white looking through the Canon FD 50/1.4 SSC and left there so the color differences (for white at least) could be compared. I only included the right and left corners cuz that's pretty much mid-area if shot on a FF anyway (not center, but mid).

This test obviously won't tell everything about a lens like how sharp it is when focused to infinity or what the bokeh is like, but I guess it's a pretty good comparison for these to show sharpness at one meter. And 1 to 3 meters is nice bust portraiture with a 50mm on the GH1.

The chart numbers are to be multiplied by 100 to get LPP (Lines Per Picture). But actually, since I was pulled out just a tad in order to use the box for framing the shots, maybe multiplying by 107 or so would be more accurate. :D I shot them all in 4x3 format on a Linhof tripod, with the 10s timer, using the 15X zoom MF assist - using the right-most red box (above) as the focus point.

The Canons seem to be the winners (in this test) but all of those are IMO excellent lenses - except the Rokkor-PF F/1.7 maybe. And it's an awesome looking antique. I have a bunch of other 50's that start at 2.0 or greater which are also very wonderful - like the 55/2.8 Nikkor Micro, the Minolta AF 50/2.8 Marco or some of the Zeiss/Jena Biotars and various Tessar implementations, etc..

I also wanted to test the Voigtlander 50/1.5 but I can't seem to find my adapter.]]>

The Irix 15mm f/2.4 lens is designed to deliver the best optical performance and match full frame DSLR cameras demands. Providing a focal length of 15mm, this new lens model is ideal for outdoor and indoor photography whether it is photojournalism, landscapes or architecture.

Innovative technology

Combining capabilities specific to analogue photography with ingenious technology and solutions, the Irix 15mm f/2.4 is the perfect tool for both professionals and hobbyists. The new special features such as focus lock, infinity click and hyperfocal scale set a new level of manual lens functionality. Focus lock enables to lock the focus ring at any time ensuring the chosen settings. Hyperfocal distance scale gives information about the accessible range for depth of field for a given aperture simply and intuitively. When the focusing ring is set in the “infinity” position, there is a noticeable “click” (infinity click), making it easier to find the value without looking.

Extraordinary optical performance

The Irix 15mm f/2.4 meets the most demanding requirements of modern cameras. Thanks to sophisticated optical construction and special neutrino coating, colour aberration, ghosting and flare effects have been reduced to the absolute minimum, so the lens is ready to meet the requirements of the 50+ megapixel sensors of the newest cameras.

The complex optical system consist of 15 elements in 11 groups. Three of the lens elements have a high refractive index and two others have been made from extra-low dispersion glass. The construction also contains two glass aspherical lenses that are responsible for extremely high image quality and improving image brightness at edges, while minimizing distortions and aberrations at the same time.

With a minimum focusing distance of 0.28 meters and 9 rounded shaped aperture blades, the lens stands for supremely smooth out-of-focus areas. Working with a narrow depth of field it allows the user to fully enjoy the bokeh effect.

Resistant to extreme conditions

Irix 15mm f/2.4 lenses are made with extreme precision, allowing them to be used in even the harshest weather conditions. Each lens is equipped with a weather sealed construction that protects the interior against dust and moisture. Thanks to inner seals they are also protected from accidental water splashes.

Prepare for more and create

Despite its short focal length and large aperture, the Irix 15mm f/2.4 is equipped with not only a front filter mount, but also has a rear gelatin filter slot. The design of the lens allows the use of 95 mm screw-in filters at the front in the petal-shape lens hood and gelatin filters at the back of the lens. This ensures unlimited possibilities for image creation.

Personalize your view

For the comfort of our customers Irix has created two versions of the Irix 15mm f/2.4 to meet their personality and individual taste.

Irix Blackstone: classic design meets maximum functionality, achieving the perfect match of innovative technology. The durable aluminium and magnesium body ensures foolproof protection of your lens, even in extreme conditions. Engraved fluorescent markings that reflect the light enable easy operation in all lighting conditions.

Irix Firefly: high quality mechanism in a handy design. Ergonomic focusing ring offers the freedom to capture the most ideal moment, whether it is big city architecture or wildlife scenery. The most lightweight lens in its class. Challenge accepted.

Ultimate precision

Each Irix 15mm f/2.4 lens leaving the factory has been properly calibrated. However, the focus calibration function provides the unique opportunity to adjust the focusing scale for a particular model of camera.

PR

The global optics brand, Samyang Optics (http://www.samyanglensglobal.com) today announced the long-awaited launch of two autofocus lenses: 14mm F2.8 and 50mm F1.4 lenses for Sony E mount Mirrorless cameras with full frame sensor size. The new 14mm and 50mm are the widest and brightest lenses in their classand offer superb quality images to photographers. This launching expands the boundaries of Samyang Optics photo lens line-up from manual focus only, to now include autofocus lenses.

Optimised Optical Design as Full Frame Mirrorless Camera Lens

Both 14mm F2.8 ED AS IF UMC and 50mm F1.4 AS IF UMC are specifically designed to work in harmony with full frame mirrorless cameras in Sony E mount. The flow of light is devised based on the uniqueness of the distance from glass to sensor in mirrorless cameras to create optimal performance. Along with portability of mirrorless lenses, the 14mm F2.8 and 50mm F1.4 are compatible with full frame sensors to deliver the wideness and sharpnessof image to photographers.

The 67mm filter diameter brings the maximum amount of light into the lens to create the best work of light in photography. The 14mm F2.8 is the widest angle available in the market and the F1.4 of 50mm and F2.8 of 14mm apertures are by far the brightest of full frame mirrorless lenses, offeringa beautiful bokeh effect and the best quality images under various exposure conditions.

Based on Samyang Optics’ exceptional optical technology, aspherical lenses have been included in both lenses to minimise aberration and unnecessary light dispersion, delivering high resolution from the centre to the corners of the image.

AF Performance and Ergonomic Design Based on Class-Leading Technology

These new products will be the first autofocus lenses in over 40 years of Samyang’s class-leading core optics technologies. Samyang has captured the essence of world leading image technology with their manual focus lenses and reinterpreted it into autofocus lenses. Photographers now can enjoy the prime manual lens image quality and autofocus lens. These new 14mm F2.8 and 50mm F1.4 are compatible with both phase detect and contrast detect sensors to operate fast and accurate focus detection.

The 67mm filter diameter is also the result of years of R&D for best handling, by adding stability to the photo-taking experience. Also the minimal and sleek design and metal-housing solidify the build quality with the internal focus system.

These two new autofocus lenses from Samyang Optics will be exhibited at the Photo & Imaging 2016 Show in Seoul, South Korea. The lenses will be globally available from July 2016. Further details, pricing and availability will follow.
