Tamron 100-400mm f/4.5-6.3 Di VC USD Review
Announced just eight months after the Sigma 100-400mm F/5-6.3 DG OS HSM Contemporary lens, the Tamron 100-400mm f/4.5-6.3 Di VC USD gives photographers a similarly priced alternative to the highly successful Sigma offering. Both lenses compete in a market segment that remains unexploited by the likes of Canon and Nikon....
Canon RF 24-105mm f/4L IS USM Review
The Canon RF 24-105mm f/4L IS USM is the first kit lens introduced with the new EOS R full-frame mirrorless system. The term 'kit lens' is misleading, though, as the Canon RF 24-105mm f/4L IS USM bears Canon’s L designation and promises professional-level performance. At the time of publishing this article,...
Canon EOS R Review
2018 was a big year for mirrorless cameras with Nikon, Canon, and Panasonic all announcing their first full-frame mirrorless systems.

Recommended Sony A7 III Settings
Released five years after the original A7, the Sony A7III marks the third generation of Sony’s ‘entry’ level full-frame mirrorless camera series. Based around an updated 24.2-megapixel back-illuminated full-frame sensor, the A7 III punches well above its weight with a rich feature including a 693 phase-detect autofocus system, 10 frames...
Sony A7 III Review
Calling the A7 series ‘entry-level’ is a bit misleading, rather it is less specialized and seeks to appeal to a broader range of photographers at an accessible price point. It doesn't offer the same high resolution as the A7R series, the same low-light and video-centric features of the A7S series...
Sony FE 70-300mm f/4.5-5.6 G OSS Review
A traditional weakness of Sony's FE lens lineup has been the number of options available at the telephoto end of the range. The issue has been somewhat rectified in recent years with the release of the Sony FE 70-300mm f/4.5-5.6 G OSS, Sony FE 100-400mm f/4.5-5.6 GM OSS and Sony...
Sony FE 24-105mm f/4 G OSS Review
Announced alongside the Sony Alpha A7RIII mirrorless camera body last year, the Sony FE 24-105mm f/4 G OSS is a significant addition to Sony’s standard zoom lens lineup for their FE mount. Before its release, Sony users had a bit of a tricky choice when it came to selecting a...
Sony FE 55mm f/1.8 ZA Lens Review
Introduced alongside Sony’s first full-frame mirrorless cameras in 2013, the Sony Sonnar T* FE 55mm f/1.8 ZA lens was the first fast-aperture, “standard” focal length prime lens available for the FE mount. The 50mm prime lens has seen a resurgence in popularity in recent years, with many new lenses in...
