The stars of Sigma's booth at this years Photokina were two new telezoom lenses - 'C' and 'S' versions of a 150-600mm F/5-6.3 DG OS HSM aimed at enthusiasts and sports / wildlife professionals, respectively. The company was also showing off its new 18-300mm F/3.5-6.3 DC Macro OS HSM 'C' for APS-C DSLRs. We headed to the company's stand on our final day at the show, and got our hands on the new gear (except the stuff behind glass). Click through to see more.

Fujifilm announced two cameras on the runup to Photokina - the X100T and X30. But the company is also showing off mockups of several new lenses, slated for release next year. We sat down with senior executives from Fujifilm earlier today, and got our hands on the samples. Click through to take a look at what's in store.

The Olympus booth was relatively quiet compared to the madhouses at Nikon and Canons' stands, which made it easier to get up close and personal with the company's new lenses. We also took a look at some of their recent cameras, and have a few cutaways, as well. Read more.

We swung by Nikon's Photokina 2014 stand to see the new D750 in action and investigate what else the company has in store for show attendees. The booth itself is a bit less flashy than some of the competitions, and distinctly lacking in cars and ladies wearing sequins, but that doesn't mean that it doesn't make an impression.

Leica announced two new M-series rangefinders at this year's Photokina, in addition to the Digital M-P released last month. The German company also unveiled a new medium-format S, which as well as high-resolution stills can capture 4K video. Naturally, we headed over to the Leica booth to get our grubby hands all over the new cameras. Click through to see more. 

It's the second day of the photography industry's biggest tradeshow and we paid a visit to the Sony booth. Hoping to catch a glimpse of the Alpha QX1 'lens-style camera' paired with a gigantic 70-200mm lens, Sony did not disappoint us. We also got our hands on a pair of new lenses. Take a look around Sony's Photokina 2014 stand with us. Read more

Leica released two new X-series cameras at Photokina this year - the X and X-E. The X-E is an update to the X-2, and the 'X' is the flagship model.

Canon's Photokina stand is popular as always. The company is eager to show off its EOS 7D Mark II to Photokina attendees, and the public in turn turned out to give the camera a try judging by the crowds at the booth.

The Panasonic Lumix DMC-GM5 borrows the styling of the fashion conscious GM1, but adds enough additional control to give it broader appeal. So while it's still a smart, diminutive thing, Panasonic has found room for a viewfinder, control dial and hotshoe. We look at the two cameras side by side and examine the changes that've been made at the petite end of the Micro Four Thirds range.

Olympus celebrates the start of Photokina with the announcement of a major firmware update for the OM-D E-M1 that enables tethered shooting, in-camera 'digital shift' keystone composition, and the E-M10's Live Composite mode.

Sony got a lot of attention when it released a pair of cameras which clip onto a smartphone last fall. They're really going to raise a lot of eyebrows now, with their QX1, which features an APS-C sensor and E-mount. Yep, an Alpha on your phone. Take a tour of the QX1 and the superzoom QX30 cameras right here.

With the camera industry moved on somewhat since the birth of the Fuji X series compact, is there still room for a 12 million pixel compact in a less-than compact body? In this opinion piece, senior contributing writer Damien Demolder ponders the very existence of Fujifim's newest X-series camera. Read more

The X30, Fujifilm's latest enthusiast compact camera, offers the same 12MP sensor and 28-112mm (equivalent) lens as the X20 but improves on its predecessor with updated ergonomics.

As Sony introduces the Alpha a5100 interchangeable lens camera, it officially leaves behind the NEX moniker its mirrorless line originated with. The a5100 picks up where the NEX-5 series leaves off, combining the 24.3 megapixel APS-C CMOS sensor of the a6000 and the more compact footprint of the NEX-5T. The a5100 also inherits many of the a6000's good qualities, including its impressive autofocus system. The a5100 also one-ups its big brother by offering 1080/60p video at 50Mbps. We took a hands-on, preliminary look at the a5100. Read more

Click through for a tour of the a5100's major features.
