New samples from the Sigma 24mm F1.4 DG HSM Art lens

We were recently lucky enough to visit Sigma's factory in Aizu, Japan, where Sigma allowed us to shoot with a pre-production sample of the recently-announced 24mm F1.4 DG HSM Art lens. The wintry landscape of the Fukushima prefecture was a nice contrast to the CP+ convention center where we last gathered some samples with this lens, and our recent samples are more representative of lens performance on a native mount body (Canon 6D). Have a look

Sigma 50mm F1.4 DG HSM 'Art' lab test report

The Sigma 50mm F1.4 DG HSM 'Art' is a fast normal prime for full frame cameras, with an unusually complex optical design. Its premium price tag of $950 / £850 makes it substantially more expensive than either its predecessor, or Canon and Nikon's 50mm F1.4 lenses. However Sigma's recent high-end offerings such as the 35mm F1.4 DG HSM and 18-35mm F1.8 DC HSM have been truly excellent, so how does the new 50mm measure up? See the lens test data and our analysis

However, no matter how hard you try, you can't make every lens perfect - as Lensrentals Roger Cicala explains in his recent blog post. Click through for more.

Need the speed? Sigma 18-35mm F1.8 DC HSM in-depth review

Sigma's 18-35mm F1.8 DC HSM has generated a lot of excitement since its announcement in April, as the fastest zoom ever made for SLRs. Designed for use on APS-C / DX format cameras, it offers a 28-54mm equivalent zoom range, and promises similar depth of field control to an F2.8 zoom on full frame. But can an F1.8 zoom really work? Read our detailed review to find out.  

Did Sigma design the Olympus M.Zuiko 75mm F1.8?

It's an open secret that many compact cameras are produced by OEMs - companies that produce large numbers of products that are then sold under other brand names. There are also consumer-grade zooms from big name manufacturers that look much alike (we know for a fact that third-party makers commonly create lenses for the bigger brands). But we were still surprised to read about Sigma's latest patent for a 75mm F1.8 prime lens...

DxOMark rates lenses for Pentax K-50, and reviews Sigma 50-500mm

Our friends and collaborators over at DxOMark have been investigating lenses for the Pentax K-50, and have just published an article assessing which score best on this well-featured little SLR. They've looked at 28 different models, from both Pentax itself and third-party makes like Sigma and Tamron, and given recommendations for the best lens to buy in various categories. This week they've also tested the Sigma APO 50-500mm f/4.5-6.3 DG OS HSM super-telephoto zoom, and compared it to the rather more expensive Nikon AF-S Nikkor 80-400mm f/4.5-5.6G ED VR.

Ditch the 'kit': Sigma 17-70mm f/2.8-4 DC Macro OS HSM 'C' review

Just posted: Our review of the Sigma 17-70mm f/2.8-4 DC Macro OS HSM | C. This lens occupies its own little niche in the market, as an upgrade to the typical 18-55mm zoom that offers both usefully extended zoom range and a faster maximum aperture. It also includes Sigma's 'Hypersonic Motor' for silent focusing, and built-in Optical Stabilisation. In the latest of our lens reviews prepared in partnership with DxOMark, we see whether it should be top of the short-list for SLR owners looking to progress beyond their kit lens.

Sigma 18-35mm F1.8 DC HSM preview updated with lens test data

We've just updated our preview of the Sigma 18-35mm F1.8 DC HSM with lens test data, courtesy of DxOMark.
