I updated my 601 to 4.1 and when I press the shutter button on my HG-SCL 4  grip nothing happens.. ( only focuses but shutter does not fire?)  Anyone experience this?

The buttons on my HG-SCL4 work fine with FW 4.1.

Fixed it! Grip wasn't connected to the body very well.

I have the SL with a pair of Sigma DG DN lenses.  Under firmware 4.0 they were working fine including various AF options including tracking.

Since the 4.1 update focus tracking no longer works with the Sigma lenses and the focus point does not reset to the center despite this being the option in the menu system.  Manual focus (AFs) is working but AFc now only working with shutter half-press and seems much more jumpy than before.

I don't have Leica AF lenses to compare with.

Anyone else noticed this?

Should I revert to firmware 4.0 (assuming this is possible), or report the issue to Leica?

You should report the issue to Leica.

Further to this, I started on a message to Leica about the problems but thought I should check again to make sure these are bugs not features.

What I find is that the location of various AF controls have been moved around in the menu system making it hard (at first) to work out how the settings interact.  In addition, the behaviour of the various controls have also changed.  Tracking can only be switched on and off with the switch on the lens in AF position but if the lens is switched to MF with tracking on, tracking stays on and is triggered by the focus button on the back of the camera (rubber button next to the display button, configurable I think) but the shutter half-press does not trigger tracking.  The effect of the AFs/AFc option (in a different place in the menu) varies depending on the state of the other controls.

I used to think that the Sony menus were confusing and appreciated the relative simplicity of the Leica menus but this update seems to have increased menu complexity alongside extra functionality.

So it's not a bug (for SL users with Sigma lenses) but a learning curve and of course Sigma lenses are not mentioned in the release notes for the firmware update.  (It is possible to use the lens updates from the Sigma website where available although the extra features seem to relate to the SL2 or SL2/S not the SL.)

Given the price and size differences between the Leica and Sigma AF lenses, this learning curve is worthwhile.

Initially firmware 4.0 for SL 601 fully supports all my SL lenses eg. SL 16-35, SL 24-90, SL 90-280, SL 100-400 & SL50. With the available downloaded firmware 4.1, the camera indicated 4.1 and with attached lens SL 16-35, it indicated lens 4.0……eventually it can’t read this lens. Thus the only lens not able to AF focus….. Counter tested this SL 16-35 lens into camera SL2, indicated camera firmware 6.0 and lens 4.0….working fine AF focus. Appreciate anyone advice or guidance to solve this issue of my SL601 with 16-35 lens.

I'm having the same issue with my 16-35 lens and the new 4.1 firmware. Autofocus on this lens doesn't work.

Did anyone get a chance to figure it out and fix the problem?

Autofocus works with my SL 601 (firmware version 4.1) and my SL 16-35 mm (firmware 4.0). I just tested AFS. AFC and back button focus (MF) in different modi.
