CTOnews.com December 17, Tenglong released a firmware update for the 18-400mm F / 3.5-6.3 Di II VC HLD (model B028) Canon bayonet.

Tenglong announced 18-400mm F / 3.5-6.3 Di II VC HLD (model B028) on the official website in October this year, informing them of possible anomalies when using the EF-EOS R transfer ring on Canon EOS R7 / EOS R10. In view of this problem, a new version of firmware has been released to improve it.

Update content

This update improves the following issues:

As the camera power is turned on / off, the AF may not work properly when the shutter key is half pressed.

Update method

Firmware can be updated via TAP-in Console (optional accessories). If the user does not have TAP-in Console, please send the camera to Tenglong Company.

Officially, the model is suitable for ultra-long zoom lenses with an 18-400mm focal length and a zoom ratio of 22.2 times for APS-C digital SLR cameras. When the 400mm telephoto end is converted to 35mm full-frame specification, it is equivalent to 620mm, which makes ultra-telephoto shooting possible. You can enjoy the unique "compression effect" and "zoom effect" of ultra-telephoto lenses. From wide-angle to long-focus, the full-focus section achieves excellent optical performance. The maximum photography magnification of 1Rank 2.9 is the icing on the cake for macro photography. CTOnews.com learned that the lens is suitable for recording the scenery, architecture, people, flowers and plants during the trip, and it is also easy to master the shooting themes such as animals and sports.
