Summary
7Artisans has released two firmware updates: V1.04 for the AF 27mm F2.8 APS-C in Sony E-mount and V1.23 for the AF 135mm F1.8 full-frame in Nikon Z-mount.
The September 3 announcement lists five improvements and fixes for the 27mm, covering autofocus and cooperation with in-body image stabilization. The 135mm update improves aperture stability.
These releases target different lens and mount combinations from the X-mount and L-mount firmware updates covered in August. Owners should therefore select the file that matches their exact lens version.
AF 27mm F2.8 Sony E: what V1.04 changes
Autofocus receives the largest group of changes. 7Artisans reports improved speed and overall performance in both AF-S single-shot autofocus and AF-C continuous autofocus. The update also fixes an issue that prevented autofocus from working correctly when using magnified view.
Version 1.04 also addresses unwanted automatic image magnification during autofocus shooting when Full-Time DMF was enabled on compatible cameras. This feature allows manual focus adjustment while autofocus is in use.
On cameras equipped with in-body image stabilization, the update optimizes the lens’s cooperation with IBIS.
Finally, it fixes frame-format switching on full-frame cameras when Auto Frame Switching is enabled. As the AF 27mm F2.8 is designed for APS-C, this change concerns the camera’s correct selection of the appropriate recording area.
AF 135mm F1.8 Nikon Z: improved aperture stability
For the AF 135mm F1.8 in Nikon Z-mount, V1.23 improves aperture stability.
The AF 135mm F1.8 for Nikon Z combines a long focal length with an f/1.8 maximum aperture. The company’s official video introduces the lens and includes sample footage.
Firmware availability
Firmware files are available from the official 7Artisans download center. The AF 27mm F2.8 appears in the APS-C lens section, where owners should select E-mount. The AF 135mm F1.8 is listed in the full-frame section, with the Z-mount file required for this update.
Before installation, check the lens model, mount and currently installed firmware version. Follow the 7Artisans instructions supplied with the corresponding download.
Our take
Version 1.04 is particularly relevant for photographers using the 27mm on Sony bodies with IBIS or relying frequently on AF-C and magnified view to check focus. These fixes address specific issues in everyday shooting. For the 135mm, V1.23’s value lies in more consistent aperture operation.
