Tamron has announced a new SP lens, the 150-600mm F/5-6.3 Di VC USD G2 (Model A022), part of their newly redesigned line of high performance lenses. This 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 two optional teleconverters, the 1.4 and 2.0x.
Delivery of the new lens in Canon and Nikon mounts will start on September 23 in the Japanese market and soon thereafter in the U.S. market (Sony A-mount to be delivered at a later date) at a price of $1399.
Below is Tamron’s breakdown of the new lens’ features:
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 an 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.
2. 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 BBAR (Broad-Band Anti-Reflection) coatings, flare and ghosting are reduced to imperceptible levels.
3. 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 86.6 in (2.2m), compared to 106.3 in (2.7m) for Model A011, and has allowed for the wonders of tele-macro photography with its 1:3.9 Maximum Magnification Ratio.
4. 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 the 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.
5. 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 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 panning.
- 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 prioritizes the stabilization of the captured images and forgoes the stabilization of the viewfinder image.
A new VC Mode can be programmed with the optional TAMRON TAP-in ConsoleTM. You can overwrite VC Mode 1 with a new VC Mode that allows stabilization to be engaged constantly for videography purposes. In this mode, the LCD screen is used.
6. New FLEX ZOOM LOCK mechanism enables locking of the zoom ring at any position
The 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 lens features the conventional Zoom Lock switch to prevent unwanted barrel extension during transportation.
7. Fluorine Coating and 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-repellent. 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.
8. Electromagnetic diaphragm system now used 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. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.
9. Lightweight and easy-to-hold tripod mount 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.
10. 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.
11. Teleconverters exclusively for the Tamron lens now developed
Two exclusive teleconverters, which perfectly match the optics of the new SP 150-600mm G2 (Model A022), offer 1.4x and 2x magnification, and provide a maximum zoom range up to 1200mm. These new teleconverters extend focal length of the master lens, making it possible to take pictures in farther ultra-telephoto ranges.
Additionally, as mentioned, Tamron announced two teleconverters that work with the 150-600mm. Right now, they are only compatible with this one lens, though more compatible lenses will likely be introduced in the future.
Delivery of the new teleconverters, each available in Canon and Nikon mounts, will start on September 23 in the Japanese market and soon thereafter in the U.S. market at a price of $419 for the 1.4X and $439 for the 2X.
Features of the new teleconverters are as follows:
1.?Increases maximum focal length
Although the maximum focal length is increased, the minimum object distance remains nearly the same, so the magnification ratio during close focusing is enhanced. Both teleconverters are carefully designed and constructed to preserve the original superior image quality of the lens. The 2.0x model uses one LD (Low Dispersion) lens element to suppress aberrations. BBAR (Broad-Band Anti-Reflection) coatings are deployed on both models to help minimize ghosting and flare.
2. Autofocus and VC features are retained with compatible lenses
Autofocus functions normally with compatible lenses (please refer to Compatible Tamron Lens List below). VC (Vibration Compensation) performance is maintained.
3. Moisture-Proof and Dust-Resistant Construction
The new teleconverters are ideal for use in outdoor photography when matched with any lens that has a Moisture-Resistant Construction because special seals that are dust-resistant and moisture-proof are used at every joint and seam.
4. Sturdy, durable barrel design
The barrel frame of the teleconverters are made of die cast aluminum, except for some parts of the exterior finish, to maintain extra strength when used with large lenses. The design utilizes a bayonet mount made of brass on the camera side and stainless steel on the lens side to ensure excellent durability even with repeated mountings and detachments.
These accessories embody Tamron’s new design that’s born from the pursuit of functional beauty and achieved by smoothly blending engineering and design enhancements. Meticulous craftsmanship is applied to every detail. The new teleconverters feature a metal lens barrel and share this same design concept. Both teleconverters provide remarkable ease of use—even the release lever offers a comfortable touch to the photographer’s finger.
