The Sony a9 is touted as the Jack of all Trades. Impressive specs, and a lot of hype coming from a devoted fan community.

However, all that glitters is not gold. The video below, shot with a Sony a9 using a $9000 Canon EF 500mm f/4 lens on a Sigma MC-11 adapter, isn’t so impressive after all. The Sony a9 is not able to track focus after the shutter has been fired. The Sony a9 just started shipping so we don’t know if this phenomenon is limited to adapted Canon lenses (guess it is).

If you are a professional photographer, stick with Canon and Nikon and stay safe with proven gear and great and reliable professional service. If you have money to waste for gadgets, get a Sony a9. The specs are truly impressive and once more show how much Sony is pushing technological innovation.

Canon EOS M6 at a glance:

  • 24.2MP APS-C CMOS Sensor
  • DIGIC 7 Image Processor
  • 3.0″ 1.04m-Dot Tilting Touchscreen LCD
  • Full HD 1080p Video Recording at 60 fps
  • Built-In Wi-Fi with NFC, Bluetooth
  • Dual Pixel CMOS AF
  • Up to 9 fps Shooting and ISO 25600
  • Combination 5-Axis Image Stabilization

Canon’s new EOS M6 got DxOMarked. The EOS M6 got a score of 78.


From the conclusion:

While early EOS M-series mirrorless cameras underwhelmed a little, the new M6 has the features and image quality to be a serious contender in the hybrid market, as long as you don’t want 4k video.

For photographers considering an update from an older EOS M, M2, M3 or M10 model, the improved specifications make the M6 a worthwhile upgrade. While the exclusion of a built-in EVF is probably a deal breaker for serious enthusiasts, they aren’t the M6’s target market, with the larger DSLR-style EOS M5 still in the Canon lineup to meet their needs. Of course you can add the accessory EVF to the EOS M6, but that adds $200 to the price, makes it bulkier than the M5, and limits the use of the hotshoe for a mounted flash, so not ideal.

Photokina, world’s leading event for photo, video and imaging will take place every year from now on

If you are into photography you likely know Photokina, the world’s leading event for everything related to photography, video and imaging.

As for now, Photokina was an event occuring every two years. Starting from this year, Photokina will take place every year.

photokina will take place annually as of 2018. It will in future thus optimally reflect the fast-paced nature and the ever briefer innovation cycles of an increasingly digitalised industry. As of 2019 the trade fair will also have a new date in May. In addition to innovations from the core areas of the imaging workflow, the entire range of products, applications and services of relevance for imaging shall in future be presented in Cologne. With these changes, the transformation process begun in 2016 shall be consistently continued: under the umbrella of “Imaging Unlimited”, photokina last year inspired both exhibitors and visitors and accessed new target groups for the industry.

“The digital transformation of the imaging industry is advancing, and thus opening up new perspectives and value creation potential. The new date and the annual cycle should in future make photokina even more attractive to all providers of the imaging ecosystem. In this way, we show the specialised trade, the media and our users an even broader bandwidth of state-of-the-art products, applications and services in Cologne which especially suits the young imaging culture,” Rainer Führes, chairman of the board of the photography industry association (PIV) is pleased to state.

Sigma 135mm f/1.8 ART review (D. Abbott)

Sigma 135mm F/1.8 ART Review (D. Abbott)

Sigma 135mm f/1.8 Art: Amazon, B&H Photo, Digitalrev, eBay, Adorama, Canon USA

Sigma 135mm f/1.8 Art at a glance:

  • EF-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.8 to f/16
  • Two FLD Elements, Two SLD Elements
  • Super Multi-Layer Coating
  • Hyper Sonic AF Motor, Manual Override
  • Rounded 9-Blade Diaphragm
  • TSC Material, Brass Bayonet Mount
  • Compatible with Sigma USB Dock

The Sigma 135mm f/1.8 ART must be an amazing lens, at least according to what reviewers say. It’s clearly another great lens by Sigma.

Canada based photographer and reviewer Dustin Abbott published an exhaustive review of the Sigma 135mm f/1.8 ART lens.

From the conclusion:

While the Sigma 135mm f/1.8 ART may not win any awards for being Sigma’s sharpest, brightest, or cheapest lens, I do think that in many ways it is Sigma’s most complete prime lens. Unlike some of the ART series, I didn’t find it clinical but instead appreciated the quality rendering from the lens. It does tend to skew white balances a little cool, and it doesn’t deliver the most deeply saturated colors out of the box, but the images process well. I have seen several excellent 135mm lenses for Canon/Nikon mounts in the past two years, including the Samyang/Rokinon 135mm f/2 and the outstanding Zeiss Milvus 135mm f/2, but both of these options are manual focus only. The Sigma 135 ART is the first 135mm lens to bring the excellence of modern lens design coupled with useful autofocus.

You can watch the 18 minutes video below for the final review, or you can head over to Dustin Abbott’s site if you prefer reading the review, and checking the many sample pictures.
