A quick reminder to those of you who were planning on purchasing new photographic equipment from B&H. Instant rebates from Nikon, Fujifilm and Sony will end tomorrow (06/29/2013). A quick recap on the rebates programs. If you buy a Nikon DSLR body, you have the option of purchasing as many lenses or speedlight units (SB-700 and SB-910) with up to $300 off per each product. While this means that you have to purchase at least one camera to qualify for additional lens rebates, some lens rebates are significant and were not part of any rebates in the past (like the new Nikon 70-200mm f/4G VR lens that I reviewed earlier this year). So this will be a great program for those that want to buy a new DSLR or want a backup camera.
I remember not that long ago there were two types of lenses. Brand lenses, those designed by known manufacturers for their own cameras, such as Canon, Nikon, Pentax and Olympus, and the cheapskate third party lenses you’d buy if you couldn’t afford the first type. Brand lenses were more expensive, but well worth the extra price. Better build quality, better optical capability, better dependability, better compatibility, better autofocus and fewer quality control and manufacturing issues were what you got for your hard-earned cash. Not to mention respectful nods from anyone spotting letters Nikkor or a red ring around the front of that lens barrel. A few years have gone by now and situation seems to be changing, however. Third party manufacturers have moved the game up and started producing some serious alternatives. Sigma is very keen to prove the point with the launch of its latest lens, the new 18-35mm f/1.8 DC HSM for APS-C DSLR cameras. In this article, I will introduce you to this new lens and give insight as to why it is such an important step forward in current smaller-format lens market.
What is it About This Lens?
In a nutshell, this new lens sports a useful wide-to-normal focal length range of 18-35mm on an APS-C sensor camera (27-52.5mm full-frame equivalent), for which it is designed. It also has Sigma’s fast HSM AF motor, which is similar to Nikon’s SWM and Canon’s USM technology. Zooming and focusing are internal, so length remains constant. The new Sigma also has 17 elements in 12 groups and sports 9 rounded diaphragm blades for smooth out of focus highlights. Some of the optical elements are aspherical while minimum focus distance is 0.28m. The lens accepts 72mm filters and is, unfortunately, not protected against dust and moisture. It’s also quite hefty at around 810g. The lens sits in Sigma’s Art lineup alongside Sigma 35mm f/1.4 HSM and is designed with aesthetic flexibility in mind. But the spotlight is the f/1.8 aperture throughout the zoom range. Oh yes. This is the first ever f/1.8 zoom lens for DSLRs.
This is an in-depth review of the Tamron SP 24-70mm f/2.8 DI VC USD – world’s first image stabilized standard zoom lens for 35mm sensor cameras that was released in April of 2012. I have been shooting with the Nikon 24-70mm f/2.8G for a while and although I love it for its super fast and accurate autofocus and durability, it has its share of problems. It is huge and heavy, has rather poor corner performance at fast apertures and suffers from field curvature issues (where sharpness is not uniform across the frame). In addition, it lacks image stabilization, which I am a huge fan of. So when I found out that Tamron released a professional 24-70mm f/2.8 lens with image stabilization, I knew I wanted to test it out and compare it head to head to the Nikon 24-70mm f/2.8G.
