Not a lot of things to report this week, but there is a new fast prime lens from TTartisan and interesting firmware updates coming for the Canon R5 and R6.

TTArtisan 23mm F1.4

The Chinese company has unveiled a new compact fast aperture prime lens for APS-C cameras, meaning it offers a 35mm equivalent field of view. It’s very light (225g) and will be available for Canon EOS M, Fujifilm X, Sony E and Micro Four Thirds. This is a manual focus-only lens. Price and date are yet to be confirmed. There will be an all-black version and one with the silver focus ring.

  • 10-blade aperture diaphragm
  • Minimum focus: 20cm

Canon EOS R5 and R6 Firmware Updates

Version 1.5.0 will bring a series of autofocus improvements. The two models will get the Vehicles Subject Detection that allows the cameras to automatically track a racing car or motorbike (first introduced with the R3). They can also prioritise the focus point on the helmet of the driver. Eye AF has also been improved and the cameras will be able to focus on the torso of a person if the eyes or face are not detected. Finally, people can be detected even if they wear helmets or goggles.

The firmware updates will be available on December 2nd, 2021.

Nikon Z 28mm F2.8

If the lens sounds familiar, that’s because it should be: Nikon has already released the SE version alongside the Z fc. Nothing changes except the exterior: the SE version has a vintage look, whereas the normal version follows the modern design of other Z lenses.
