Sigma 18-35mm f/1.8 Review

« »

This is an in-depth review of the Sigma 18-35mm f/1.8 DC HSM Art lens, world’s first constant f/1.8 zoom lens for DSLR cameras that was announced in April of 2013. Despite the recent trend of manufacturers to move their customer base to full-frame format, Sigma took a bold move and announced the professional-grade Sigma 18-35mm f/1.8 Art for DX/APS-C format only. With a focal range equivalent to 27mm-52.5mm in 35mm format, the lens provides a good range to work with for a variety of different needs and applications. And with its fast constant aperture of f/1.8, the Sigma 18-35mm opens up opportunities to shoot in low-light situations, something that was previously only possible with fast aperture prime lenses. Lastly, Sigma’s pricing of $799 MSRP for the lens made it the top choice in terms of value when compared to pro-grade lenses such as the Nikon 17-55mm f/2.8G DX, which sells for almost twice as much and does not offer the same low-light advantages.

Sigma 2.0x Teleconverter Review

This is a detailed review of the Sigma 2.0x Teleconverter EX APO DG for the Nikon mount. I had a chance to test out this teleconverter, along with the 1.4x Sigma teleconverter when working with the Sigma 120-300mm f/2.8 lens, so I wanted to share some of my findings and compare the teleconverter to its Nikon counterpart, the Nikkor TC-20E III. In this review, I will go over the optical characteristics of the Sigma 2.0x teleconverter and talk about its performance when using both Sigma and Nikon super telephoto lenses.

Sigma 35mm f/1.4 Review

« »

This is an in-depth review of the Sigma 35mm f/1.4 DG HSM prime lens that was announced at one of the largest photo shows in the industry, at Photokina in Germany on September 17, 2012 for Sigma, Canon, Nikon, Pentax and Sony mounts. The announcement came on the same day with Sigma’s new restructuring of its lens lineup, with three new categories that would differentiate different types of lenses: “Contemporary” for small and lightweight consumer lenses, “Art” for professional zoom and prime lenses and “Sports” for long lenses targeted at sport and wildlife photography. Being a professional-level lens targeted at a variety of photography needs, including portraiture, landscapes and travel, the 35mm f/1.4 is the first Sigma lens that falls into the “Art” category.

Thanks to its large aperture of f/1.4, the lens is not only great for low-light photography, but it also can effectively isolate subjects from the background due to shallow depth of field, beautifully rendering background highlights, also known as “bokeh“. Unlike cheaper cropped-sensor lenses, the Sigma 35mm f/1.4 is designed to work on both APS-C / DX and full-frame / FX sensors. The lens rivals other fast 35mm primes from Nikon, Canon and Sony, and unlike the branded versions that are in the $1500 range price-wise, the Sigma is actually the cheapest of the group at $899 MSRP.
