Sigma released a service notice for the Sigma MC-11 mount adapter (Canon EF or Sigma SA lenses to Sony E camera bodies) on Auto-Focus issues that may occur when using AF-S mode with telephoto lenses on a Sony a9.

Thank you for purchasing and using our products.

We have found that the combination of SIGMA MOUNT CONVERTER MC-11 (SA-E and EF-E) and some of SIGMA’s interchangeable zoom lenses may not focus precisely, if it is attached to SONY a9 (ILCE-9), released by SONY in May in 2017.

When using AF-S mode and shooting in telephoto range, it could occasionally display the shot is in focus, although it may not be spotted properly on the subject.

We are afraid of this inconvenience caused to the customers who use these products.

We are now investigating the phenomenon and will make a further announcement on the website shortly.

We appreciate your continued support for our company.

For further information, please contact your nearest authorized SIGMA subsidiary / distributor.

  • 24.2MP Full-Frame Stacked CMOS Sensor
  • BIONZ X Image Processor & Front-End LSI
  • 693-Point AF System & 20 fps Shooting
  • Blackout-Free Quad-VGA 3.7m-Dot OLED EVF
  • Internal UHD 4K Video Recording
  • 5-Axis SteadyShot INSIDE Stabilization
  • 3.0″ 1.44m-Dot Tilting Touchscreen LCD
  • ISO 204,800, Silent Electronic Shutter
  • Built-In Wi-Fi/Bluetooth, Dual SD Slots
  • Integrated LAN and PC Sync Terminals

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

EOS M6

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.
