Today, Leica Camera has released firmware version 3.3 for the SL (Typ 601) full-frame mirrorless camera. In addition to adding compatibility with the new Leica FOTOS app for wireless control (learn more about the new app here), firmware 3.3 adds a few new settings and tweaks for both power saving and auto review.
The first major change is a new option under Auto Review called “Shutter pressed.” This allows the image you just took to remain on the screen (or in the viewfinder) for review as long as you continue to hold the shutter after you've taken the shot. Personally I always just turn Auto Review to “off” but for some users this setting may be handy.
Power Saving Mode was introduced in firmware 3.2 as a way for users to stretch the life of the camera's battery. With this setting turned on in 3.2, the camera would automatically power off after 3 seconds of inactivity which was simply way too quick! This has been lengthened to 10 seconds in firmware 3.3, which in theory will still help squeeze every last drop out of a battery if you don't have a fully charged spare nearby.
The new firmware can be downloaded here: Leica SL Firmware 3.3 – (It’s a big file at 112MB, so be sure the LFU file is 100% downloaded before you copy it to your SD card!) Remember, you must have a FULLY charged battery in your SL when doing the firmware update, as the process can take up to 10 minutes to complete the update. Be sure your SD card with firmware is in slot 1 (the top slot). If you need help updating, scroll down to see our step-by-step video tutorial.
