Lens Reviews

Tamron has a long history of producing versatile, do-everything lenses and the Tamron 35-150mm F/2.8-4 Di VC OSD (Model A043) continues with that heritage. I received the Canon EF-mount version of the lens for testing, but a Nikon F-mount version is also available at the same price. While designed for Canon’s full-frame EF-mount cameras, the Tamron 35-150mm lens can also be used with their APS-C models where it produces a field-of-view equivalent to 56-240mm.

There is nothing more invigorating for a zealous photographer than putting a brand new lens on a familiar, reliable DSLR body. The world looks different through a new lens, and the tableau of photo opportunities hits the reset button, refreshing all of the possibilities. My experience with Tamron’s new Tamron 70-210mm F/4 Di VC USD tele zoom brought this realization into focus, no pun intended.

Tamron has always been a pioneer in the do-everything zoom lens category and their new AF18-270mm F/3.5-6.3 Di II VC PZD lens is no exception. Don’t be intimidated by those initials—it’s all good stuff—and I’ll get to them shortly. The 18-270mm F/3.5-6.3 is part of Tamron’s Di II family of lenses that are engineered specifically for digital SLRs with image sensors measuring 24x16mm, typically referred to as APS-C. The sensor size of the Canon EOS 50D I tested the lens with measures 22.3x14.9mm so I guess that’s close enough. The 15x zoom range of the lens provides a 35mm focal length equivalency of 28.8-432mm with the Canon EOS 50D’s 1.6x multiplication factor, but that will be slightly different for the Nikon and Sony versions that are also available. Shooting full frame? Check out Tamron’s Di lens series for 35mm film cameras or digital SLRs featuring larger (24x36mm) sensors.

Tamron’s new SP 15-30mm f/2.8 Di VC USD G2 lens ($1299) continues a trend that many camera and lens manufacturers have embraced in recent years. This new Tamron 15-30mm lens is fast, big, expensive and designed for photographers who expect optical excellence. As part of Tamron’s Di lens series, the SP 15-30mm f/2.8 Di VC USD G2 is available for Canon and Nikon full-frame DSLRs and APS-C cameras where it produces a 24-48mm equivalent focal length range.

I tend to travel on the wide side when it comes to lens selection, so it was exciting to get ahold of Tamron’s new super telephoto zoom—the SP 150-600mm f/5-6.3 Di VC USD G2 (Model A022). And what better way to give this big beauty a try than to take it on safari?

The difference between a “constant” aperture zoom and other standard zooms is that when you increase the focal length on the standard zoom the maximum aperture narrows. This might make the difference between being able to hand hold or not when zooming in, and may indeed force the use of higher ISOs. Known as “fast” lenses, constant aperture zooms are pricier and bulkier than their variable-aperture counterparts. And to sweeten the pot, we’ve seen more and more fast lenses with built-in image stabilization, which gets you even more low light and steady shot capability.

To make a better lens, one that avid photographers might even be inclined to leave on their DSLR camera permanently, Tamron set aside all of their former notions about lens design and construction and went straight back to the basics with the new Tamron SP 35mm f1.8 Di VC USD (Model F012) and SP 45mm f1.8 Di VC USD (Model F013) prime lenses, which are the subjects of this review.
