Sigma service notice for Auto-Focus issue with Sigma MC-11 mount adapter on Sony a9

Sigma MC-11 at a glance:

  • Adapt SA/EF-Mount Lens to Sony E Body
  • Integrated LED Displays Compatibility
  • Maintains Autofocus and Auto-Exposure
  • Supports In-Camera Correction Features
  • Flocked Interior Reduces Reflections
  • Retains EXIF Data

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.

Using big white Canon telephoto lenses with the MC-11 adapter on a Sony a9 may lead to such AF issues. You may want to have a look here.

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.

All that glitters is not gold: Sony A9 not ISO-invariant and sacrifices dynamic range for speed

There is no free lunch and anything comes at a price. This appears to be true especially for Sony gear, always hyped and most of the time only because of the specifications sheets.

DPReview wanted to know better. They put the Sony a9 on their test bench, and found some interesting things. So, how does the powerhouse a9 perform when it comes to ISO-invariance (what is it?) and dynamic range.

DPReview found out that the Sony a9 is not ISO-invariant, and that “the camera is adding a fair amount of read noise that results in noisy shadows, limiting dynamic range at base ISO“. They also found that the Sony A9 sensor “was likely optimized for speed at the expense of low ISO dynamic range“.

What does all this mean? According to DPReview “this limits the exposure latitude of a9 Raws, so you’ll have some limited ability to expose high contrast scenes for the highlights, then tonemap (raise) shadows in post“.

Off Brand News: Sony Releases High-Speed Vision Sensor that Makes Detection and Tracking of Objects at 1,000 fps Possible

IMX382
High-speed vision sensor IMX38

Sony pushing technological innovation. Sony press release:

Tokyo, Japan—Sony Corporation today announced the release of the new IMX382 high-speed vision sensor, which enables detection and tracking of objects at 1,000 frames per second. Sony will begin shipping samples in October 2017.

This vision sensor features a stacked configuration with a back-illuminated pixel array and signal processing circuit layer. The circuit layer is equipped with image processing circuits and a programmable column-parallel processor, delivering high-speed target detection and tracking. This configuration enables high-sensitivity imaging thanks to the back-illuminated pixel array, with target detection and tracking at 1,000 frames per second. The new sensor uses information such as color and brightness obtained from pixels to detect objects, then extracts the object’s centroid, moment and motion vector, and finally outputs the information from the vision sensor in each frame.

This vision sensor has achieved imaging, target detection and tracking at 1,000 fps on a single chip. This not only expands the scope of application, but delivers new value that was difficult to obtain with conventional systems.

The Sony a9 is touted as Canon and Nikon killer over the Internet. Sony pushes the Sony a9 as a sports camera but as far as I know there are no serious sport lenses for the a9 yet.

What do you think, will professional sport photogs abandon their battle-proven gear for this camera? I can’t help but to me Sony cams still feel like toys.
