Sigma 12-24mm F4 DG HSM Art Lens Review

Published on November 22, 2016 by in News

The Sigma 12-24mm F4 DG HSM Art was first announced September 16th, 2016. This is Sigma's widest zoom lens offering to date and joins Sigma's growing list of Art lenses. The lens is priced at just under $1600, which makes it a fierce competitor to Canon's EF 11-24mm F4L USM lens which is priced at just under $3,000.

The Sigma is available in Canon, Nikon F (FX) and Sigma SA Bayonet mounts and will most likely appeal to landscape and architecture photographers that are looking for an extremely wide field-of-view (12mm gives around a 122° diagonal field of view).

The looming question is: does the extreme difference in price effect the build quality and performance of the Sigma? In this review we will be looking at the Sigma's performance and just how it stacks up against the Canon 11-24mm F4L.


If you're an APS-C shooter, the Sigma can be utilized on that platform with an equivalent focal length of 19-38mm and an equivalent aperture of F6.4. It's worth noting however that Sigma already offers a considerably less expensive 10-20mm F3.5 which would be a 16-32mm F5.6 equivalent, which would be a much better wide-angle option. For this reason we're not going to consider this lens for use on APS-C in this review.

Sigma 12-24mm F4 DG HSM Art Headline Features

  • 12-24mm focal length
  • F4 maximum aperture
  • Ring-type Ultrasonic Focusing
  • Available in Canon EF, Nikon F (FX) and Sigma mounts

Dimensions 132mm (5.2") x 102mm (4.0") 132 mm (5.2?) x 108 mm (4.25?)
Hood Included Yes (built in) Yes (built in)

The Sigma and the Canon share a rather large number of the same features with respect to lens design. The main differences between the two lenses are highlighted in green. The Canon has a slight edge over the Sigma in terms of build quality with full weather sealing, where the Sigma offers a 'moisture resistant' rubber gasket on the lens mount and water-repellent coatings on the front and rear lens elements.

Both lenses are very heavy and are nearly identical in size and shape, and both feature built-in lens hoods. Neither lens accepts standard screw type filters, but the Canon has a slot to accept rear gel filters. The Sigma has that familiar Art build that feels very robust in hand but lacks the same 'sealed' feeling that the Canon lens provides due to its water resistant external construction.

The Canon has a slight advantage over the Sigma in terms of the zoom method as the Sigma has an external extending zoom whereas the Canon's is internal. Being that the Sigma isn't fully weather sealed this could be a weak point in the design in terms of moisture penetrating the lens during adverse or wet weather conditions. 

With these specifications in mind, we will now be looking at how well the Sigma performs to determine how it fairs in our head-to-head comparison with the Canon 11-24mm F4L.

Godox launches mini radio flash unit for Sony mirrorless cameras

Published on November 22, 2016 by in News

Flash and accessory manufacturer Godox has announced a new small flash unit that it says is designed to go with the Sony mirrorless range of cameras. The Godox TT350S features 2.4GHz radio control and TTL exposure metering, and offers a guide number of 36m@ISO 100. The company says that the unit is compatible with the Sony a7R II, a7R, as well as the a58 and a77ll SLT cameras. Some RX models are also able to pair with the unit.

The radio controlled system allows the TT350S to work alongside other Godox radio flash units and studio heads, and the flash can operate as a master or slave in multiple-head set-ups. Three groups are programmed into the control system along with 16 channels, while the maximum working range is said to be 30m. High speed sync is provided via an HSS mode that can work with shutter speeds of up to 1/8000 sec, and the unit can be switched from TTL to manual operation to make use of 22 output levels from 1/128th power. An automatically zooming head covers focal lengths of 24-105mm, and a hinge allows the head to tilt but not to swivel.

The TT350S is powered by two AA batteries which the company claims should be good for 210 full power bursts. There is no official pricing yet, but one UK ebay seller is offering pre-orders for £73 and says delivery is expected early January.

For more information about the TT350S visit the Godox website.

Apple’s Phil Schiller explains why the new MacBook Pro doesn’t have an SD card slot

Published on November 3, 2016 by in News

There's a fair amount of controversy surrounding Apple’s newly unveiled MacBook Pro laptops, with one major criticism from photographers focusing on the removal of the SD card slot. Owners must use an SD-to-USB adapter to physically transfer files from a card to the laptop, otherwise wireless transfer is the only option. When asked about this design decision during an interview with The Independent, Apple's Phil Schiller explained that SD card slots are 'cumbersome.'

When asked why the new MacBook Pro laptops don’t have an SD card slot, Schiller explained:

"Because of a couple of things. One, it’s a bit of a cumbersome slot. You've got this thing sticking halfway out. Then there are very fine and fast USB card readers, and then you can use CompactFlash as well as SD. So we could never really resolve this – we picked SD because more consumer cameras have SD but you can only pick one. So, that was a bit of a trade-off. And then more and more cameras are starting to build wireless transfer into the camera. That’s proving very useful. So we think there’s a path forward where you can use a physical adaptor if you want, or do wireless transfer."

During the end of the interview, Schiller admitted that the level of criticism around the new MacBook Pro ‘has been a bit of a surprise.’ He went on to say that he has 'never seen a great new Apple product that didn’t have its share of early criticism and debate — and that’s cool. We took a bold risk, and of course with every step forward there is also some change to deal with.'
