Laowa is one of the brand names used by Chinese manufacturer Venus Optics. We previously encountered Laowa when we produced a sample gallery of the full-frame Zero-D 12mm F2.8 – a lens that claims zero distortion and has exceptionally well corrected barrelling for any focal length let alone one with such a dramatic angle of view. This 7.5mm F2 lens is designed for Micro Four Thirds cameras and makes no such distortion claims, but is one of the widest focal lengths for the system and certainly stands out for its combination of wide angle and wide maximum aperture.

The lens is small but weighty, its solidity lending it a feel of a product well made. It is actually very nice to use, focuses smoothly and its 46mm thread means filters can be used – with care. It is manual focus, with the infinity setting at the left of the scale as you look down from the shooting position. The aperture ring doesn’t unclick and offers the smallest space between the penultimate F16 and ultimate F22 settings. It has a depth of field scale marked on the barrel along with distances, but I’m unconvinced that either is especially useful.

These sample images have been made using the lens on the Panasonic Lumix DC-GH5.

DP Review Latest news - Fri, 08/04/2017 - 10:38

Hong Kong camera company Yongnuo, known for its affordable lighting gear and knockoff Canon lenses, has launched its first Li-ion powered speedlite: the YN686EX-RT flash for the Canon RT system.

The Speedlite—which was quietly released a couple of months ago—is available through eBay and Amazon and features an integrated 2.4GHz transceiver and a 2,000mAh Li-ion battery able to power 750 full-power flashes. This model can be used as either a master or a slave, and it offers optical slave triggering, according to the Speedlite's product page.

In addition, the Speedlite YN686EX-RT features a dot-matrix LCD display that shows the battery charge level, a USB port for firmware updates, and an electric zoom lamp head with a 20 - 200mm range. Other features include high-speed sync with shutter speeds up to 1/8000s, a stroboscopic mode, and support for both Custom Functions Setting and Auto-Save Setting.

Yongnuo's Speedlite YN686EX-RT is available online starting at $150 USD.

The Dell Canvas 27-inch 'horizontal smart workspace' is now available to buy for $1,800

DP Review Latest news - Fri, 08/04/2017 - 08:35

The massive touchscreen 'horizontal smart workspace' Dell unveiled during CES 2017 is now available to purchase, and a little bit cheaper than expected, at least for now.

Called the Dell Canvas, this 27-inch display is designed specifically for artists and other creatives who need a large visual workspace in which to edit photos, create graphics, or digitally paint. While Canvas resembles Microsoft's alternative, the Surface Studio, Dell's product is merely a very large display, meaning buyers will need to buy a PC separately to connect to the display.

Dell Canvas features a massive 27" QHD Adobe RGB touch screen designed to rest horizontally on a desk. The display is protected by Corning Gorilla Glass with an anti-glare surface. Joining the display is a pen with multiple tip options for simulating various textures—combine this pen with a total lack of input lag and you get an experience that Dell says is "as close to sketching on paper as possible."

Also available with the Canvas is a totem (knob) for accessing software menus quickly with the user's free hand. The totem can be positioned wherever is most comfortable on the screen, and it can be used alongside a second totem if desired. As for Canvas itself, users can optionally prop the display up into 'Draftsman' mode via a built-in kickstand. The kickstand can be extended in 10-degree increments up to 80-degrees.

Canvas is available now from Dell's website, where it currently starts at $1,800 thanks to a discount promotion (MSRP is $2,000). Dell offers the display with an optional VESA mount (+$200) or articulating stand (+$500), as well.

Sigma announces firmware update for Sigma 100-400mm f/5-6.3 OS Contemporary for Canon

DP Review Latest news - Fri, 08/04/2017 - 08:06

Sigma has announced a firmware update for its SIGMA 100-400mm F5-6.3 DG OS HSM Contemporary lens for Canon mount. Version 1.02 of the firmware fixes problems with the optical image stabilization when the lens is attached to Sigma's Sony E-mount converter MC-11 EF-E.

As usual, users who own the Sigma USB dock can update the firmware via the Sigma Optimization Pro software. Users who own the MC-11 converter can update by connecting the latter to a computer via USB-cable. In both cases, you should make sure you are running the latest version of Sigma Optimization Pro which is 1.4.1 for Windows and 1.4.0 for Macintosh computers.
