A while back, Tamron stated that they were working on a killer wide angle zoom lens in the form of the 15-30mm f2.8 lens. Today, the company has made it official. So what’s so special about this lens? Well according to reports, it’s supposed to be able to work with 50MP sensors. But that hasn’t proven yet. What we indeed do know is that it has an f2.8 constant aperture throughout the range.
The Tamron 15-30mm f2.8 Di VC USD lens has 18 elements in 13 groups, an XGM lens element at the front (eXpanded Glass Molded Aspherical), an eBAND coating to prevent reflections, nine aperture blades, and a fluorine coating on the front element.
We’re working on calling one in for review. Want one? Adorama currently lists them for $1,199 and has free shipping for Canon, Nikon and Sony DSLR mounts.
Sony’s rumored 50MP sensor is quickly becoming the mythological unicorn of the photo industry as more early reports leak its existence. Now Sony Alpha Rumors reports that Sony has briefed Tamron to develop a new line of SP.2 lenses to work its new “around 46MP” full frame sensors.
Supposedly Tamron has actually already introduced the first lens of this new SP.2 line with the 15-30mm f2.8 DI VC USD. Although the A-mount lens was announced at Photokina this September, it will purportedly work just fine on Sony’s rumored 50MP sensor.
Tamron has also been said to be working on the design of two prime lenses, which will be sharp enough to stand up to the scrutiny of such a high-resolution sensor. We’ve reported on the way lens technology has struggled to keep up with the blistering advancement of sensors, so it will be interesting to see what manufacturers can pull out of their hats this time around.
The same source claims Sony will introduce its pixel rich sensor for both A- and E-mount cameras.

The term bokeh colloquially refers to the quality of the out of focus area in an image. But over the years, it has come to be more associated with the whole out of focus area to begin with. In fact, it’s something that many photographers, enthusiasts and others become obsessed with. To get it, you need lenses with wide apertures and generally longer focal length lenses–though some wider options can do a great job too.
In our tests over the years, we’ve run across lenses from different manufacturers that exhibit some incredible bokeh. Here are some of our favorite lenses with the best bokeh.

This lens features 18 elements in 13 groups, aspherical elements, low dispersion elements, an ultrasonic silent drive motor, vibration compensation with three ceramic ball bearings, and a new eBAND coating. According to them, the new coating is “A nano-structured layer (1nm = 1/1,000,000mm), with dimensions smaller than the wavelengths of visible rays of light, is deployed on top of multiple coating layers to maximize efficiency.”
“Reflections occur at the interface between the lens and the air because of the difference in refractive indices of the two substances. The nano-structure of the eBAND Coating renders an extremely low refractive index by minimizing the differential with that of air while actively inducing air to its own structure, thus significantly suppressing the extent and degree of reflections.”
More tech specs are after the jump. We also have no word yet on pricing.

Tamron has announced a trio of lenses for cameras of all sizes from micro-four thirds, mirrorless APS-C bodies, and all the way to full-frame Canon and Nikon DSLR shooters. First up though we’re going to talk about Tamron’s first ever all-in-on zoom lens for Micro Four Thirds cameras 14-150mm F3.5-5.8 Di III.
Designed for Olympus and Panasonic cameras such as the OMD EM10 and GX7, the lens offers up an equivalent focal length of 28-300mm for a seriously wide range. Despite this long zoom range Tamron decided not to include vibration compensation to have a tripod handy when shooting at longer focal lengths. As a trade off for the missing VC feature, the lens is fairly compact and it has a filter diameter of just 52mm. The 14-150mm F3.5-5.8 will be available starting June 26th for $589.

I have tested a few long lenses here. They were mostly prime lenses. The Tamron 150-600mm f5-6.3 is one of the latest zoom lenses from this third party lens maker. It is a company with a long history in the photography world. I recently purchased their 70-200mm f2.8 and was eager to try this new telephoto zoom. What mattered to me about this lens most was its performance. During this review period, we were at the tail end of some psychotic weather. Snow was still everywhere. [click to continue…]
