Tokina 50-135mm f/2.8 Pro DX AF Review



A great range for 1.5x crop-factor sensors, the Tokina 50-135 f/2.8 fits right in where the 70-200 range used to be on 35mm SLRs. I love my Sigma 70-200 f/2.8, but sometimes I sure wish I could get that extra 20mm that this new Tokina offers. Check out Popular Photography’s review of this new lens. Also, note that Sigma’s got a similar lens with their little brother to my beloved 70-200, the Sigma 50-150 f/2.8 EX HSM.

How about that Sigma f/2.8 200-500? Holy cow! That’s a constant f/2.8 throughout the zoom range! Word is that its 35 lbs and will cost something like $9,000 (US) when released.

You got a monopod for that?

TAMRON SP AF70-200MM F/2.8 DI LD (IF) MACRO

Tamron 70-200 f/2.8Looks like Tamron is joining the popular and crowded 70-200 f/2.8 market. If it’s priced in the same range as the Sigma (about $800), this may be another good alternative to the pricey 1st party 70-200 f/2.8 lenses out there. For the details on the new lens, read the press release below.

Mr. Morio Ono, President of Tamron Co., Ltd., has announced the development of the SP AF70-200mm F/2.8 Di LD (IF) MACRO, a lightweight, high-performance and fast tele-zoom lens designed for SLR cameras with full-size image sensors.

The new SP AF70-200mm Di LD (IF) MACRO (Model A001) is an F/2.8 fast tele-zoom designed for full-size format SLR cameras. It inherits the product concept of the award-winning SP AF28-75mm F/2.8 XR Di (Model A09) standard zoom lens that is highly acclaimed for its compactness and speed, which lets photographers enjoy a high cost to performance uniqueness.

While overall dimensions are confined to the absolute minimum, the new SP AF70-200mm F/2.8 Di LD (IF) MACRO zoom lens is packed with features that allow stress-free photography: a versatile MFD (minimum focusing distance) of just 0.95m (37.4) over the entire zoom range; an excellent maximum macro magnification ratio of 1:3.1 at f=200mm; and an advantageous internal focusing (IF) system. The new tele-zoom lens enables the user to cover a desirable focal length range of 70mm medium telephoto to 200mm telephoto when mounted on full-size format SLR cameras and a focal length range from 109mm to 310mm equivalent* ultra telephoto (7°59′ angle of view) when mounted on a DSLR camera with an APS-C sized imager.

(*) The ratio Tamron uses to convert from full-size to APS-C focal length is 1.55X.

MAIN FEATURES
1. 0.95m (37.4) MFD over the Entire Zoom Range for 1:3.1 Maximum Magnification Ratio
This zoom lens, designed for use with full-size format SLR cameras, boasts a fast maximum aperture of F/2.8, yet it allows close-focusing down to 0.95m (37.4) over the entire zoom range. The maximum magnification ratio is 1:3.1 at the 200mm tele-end. The filter diameter is confined to φ77mm as a result of the use of an advanced optical design pursuing optimum optical power distribution.
2. Soft Out-of-Focus Effect and Sharp Depiction
In order to realize soft out-of-focus effect and sharp depiction performance at the same time, the zoom lens uses three LD (low dispersion) elements. As a result, the optical system effectively compensates for lateral and on-axis chromatic aberrations that are major image-degrading factors in telephoto photography, in order to provide edge-to-edge sharpness and high-contrast image quality with flat-field characteristics over the entire zoom range in various photographic situations.
3. Lightweight, Yet Fast F/2.8 Maximum Aperture
The lens features a fast maximum aperture of F/2.8, yet it weighs a mere 1,112.6 grams (39.2oz.)*, since it uses barrel parts made of engineering plastic materials having excellent dimensional stability and sufficient strength for professional use and even industrial applications.
(*) As of February 2007, based on Tamron’s research of lenses in the same class, excluding the tripod base.
4. Internal Surface Coatings Minimize Ghosting and Flare
Through the use of “Internal Surface Coatings (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coatings to prevent reflections from lens surfaces, ghosting and flare due to reflections that occur when light enters through the front element as well as reflections caused by the imager itself in the mirror box are reduced to the absolute minimum.
5. One-touch AF/MF Switchover mechanisms (for Canon and Nikon only)
The models for Nikon and Canon cameras are equipped with AF/MF switchover mechanisms to allow one-touch switchover from AF mode to MF mode or vice versa electronically and mechanically by simply sliding the button. (Sony and Pentax systems require AF/MF switchover operation on both the camera and lens.)
Since the lens uses an IF (internal focusing) system, the focusing ring does not rotate during focusing, which ensures good holding balance at all times. In the MF mode, focusing is performed as easily and comfortably as with an MF lens. Since the overall length of the lens does not change due to zooming or focusing, it offers excellent operability and holding balance.
6. Detachable Tripod Grip Ring
The lens is supplied with a lightweight and rigid aluminum removable tripod socket.
7. Flower-shaped Lens Hood
A flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.

Tamron 28-300 VC (Vibration Compensation)

Tamron 28-300 VCLooks like Tamron is jumping on the super-zoom image stabilized band wagon the new Tamron 28-300 f/3.5-6.3 XR Di VC lens that was announced today. Bob Atkins has a handy preview article. You can also check out the features in the press release below.

PRESS RELEASE

Mr. Morio Ono, President of Tamron Co., Ltd., has announced the successful development of the AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens, a high power zoom lens designed for SLR cameras with full-size format(Model A20), now equipped with a Vibration Compensation (VC) mechanism. The AF28-300mm F/3.5-6.3 XR Di VC is the ultimate high power zoom lens that covers everything from wide-angle to telephoto and macro. Tamron has incorporated a Vibration Compensator, an anti-shake mechanism developed by Tamron, into the highly versatile zoom lens. The new AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens offers the convenience, comfort and versatility of a high power zoom lens and the capability to reduce hand-shake blur on SLR cameras using either APS-C size or full size format imagers.

When the AF28-300mm F/3.5-6.3 XR Di VC is used with a full size format SLR camera, it covers the tremendous focal length range from 28mm in wide angle to 300mm ultra telephoto. When mounted on a DSLR with an APS-C sized imager, the lens covers a 43mm wide angle to 465mm equivalent ultra telephoto* (full size format equivalent, in a diagonal angle of view of 5°20′).

(*) The ratio Tamron uses to convert from full size format to APS-C focal length is 1.55X.

MAIN FEATURES

1. VC (Vibration Compensation) Mechanism Reduces Hand-shake

The proprietary VC (Vibration Compensation) mechanism developed by Tamron features a triaxial configuration using three pairs of driving coils and slide balls around the compensator group of the lens’ optical system. Since the compensator lenses are supported with rolling friction of the balls, the response performance is enhanced and the construction is simple, which results in the compactness of the lens. The lens incorporate a highly accurate gyro sensor for detecting hand-shake, which, combined with a 32-bit RISC CPU, offers comfortable anti-vibration effects.

2. Outstanding Design Realizing High Zoom Power, VC Mechanism and Compactness

The AF28-300mm F/3.5-6.5 XR Di VC integrates optical technologies that Tamron has accumulated as the pioneer and leader of high power zoom lenses in order to realize the desired compactness even while incorporating the VC mechanism. The optical system uses a number of lens elements made from special optical glass materials including XR (high refraction index) glass elements, GM (glass-molded aspherical lens) elements, hybrid aspherical elements, LD (low dispersion) glass elements to compensate for on-axis and lateral chromatic aberrations and AD (anomalous dispersion) glass element. The lens offers high contrast, high resolution performance and flatness of the image field as a one-does-it-all zoom lens designed to match the characteristics of DSLR cameras.

3. Revolutionary MFD of 0.49m (19.3″) throughout the Zoom Range Provides 1:3 Macro Magnification Ratio

The AF28-300mm F/3.5-6.3 XR Di VC LD MACRO boasts an MFD (minimum focusing distance) of 0.49m (19.3″) over the entire zoom range, a top-class closing focusing capability among high power zoom lenses for full-size format SLR cameras, which provides the remarkable maximum macro magnification ratio of 1:3 at the 300mm telephoto end.

4. Internal Surface Coatings Minimize Ghosting and Flare

Through the use of “Internal Surface Coatings” (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coatings to prevent reflections from lens surfaces, ghosting and flare due to reflections that occur when light enters through the front element as well as reflections caused by the imager itself in the mirror box are reduced to the absolute minimum.

5. Ultra-high Zoom Power, yet Lightweight and Compact Design Thanks to New Mechanical Devices

Tamron has reviewed the roles that respective barrel parts play in order to achieve the high power, compactness and light weight. As a result, dimensional increases are confined to a mere 17.8mm (0.7″) in overall length and about 5mm(0.2″) in diameter, when compared with the existing AF28-300mm (Model A061), despite the incorporation of the VC mechanism.

6. Zoom Lock Mechanism for Enhanced Portability

The zoom lock prevents unwanted barrel extension when carrying the lens/camera combination over the shoulder.

7. Flower-shaped Lens Hood

A flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.

Sigma’s 18-200 Stabilized Lens Finally Available

Sigma 18-200mm f/3.5-6.3 OS

Ok, not just yet, but you can now pre-order it now through Amazon in Canon, Nikon and, of course Sigma mounts. This thing was announce at Photokina last fall. Finally, it looks like it will actually release (ship?) on May 10, 2007. Canon is the company that really needed this lens though. Nikon has the wonderful 18-200 VR already. I’ve even been contemplating picking up a D40 or D50 (I’m a Canon user) just so I could have the 18-200 VR to carry around on family vacations and outings. I’m looking forward to reading some reviews on this lens and I’ll be sure to pass along my thoughts if I end up picking one up. If it lives up to the hype, it looks like a real bargain in the $550 neighborhood.

Canon EF 28-80mm f/3.5-5.6 II Lens Reviews

The Canon EF 28-80mm f/3.5-5.6 II lens is standard zoom lens with the same optical system, construction, and exterior as the EF 28-80mm f/3.5-5.6 V USM. The difference is that it uses a DC motor instead of a USM to drive the AF. It was included as a kit lens with older entry level Canon SLRs back in their heyday and is generally regarded as having rather poor optical quality.


Reviews

The Digital Picture

The Canon EF 28-80mm f/3.5-5.6 II Lens is very soft wide open – especially at 80mm. Stopping down at least 1 f-stop is required to get reasonable sharpness. Corners are soft at 28mm.

Fred Miranda Forums User Reviews

The Canon 28-80 may be a kit lens but it comfortably outperformed the Sigma zoom in my tripod-mounted test shots at all apertures within its limits at 28mm, 50mm and 70mm.

Where to Buy

First off, consider going to your local camera store (and I don’t necessarily mean Wolf Camera at the mall). By going to your local camera store, you’re supporting your community and you just might build a lasting relationship with people you can rely on when you need some help or answers. If you’re buying online, I recommend sticking with Amazon, B&H Photo or Adorama. These three vendors are reliable, trustworthy and generally have the best (legitimate) prices.
