Now this lens has a linear focus throw on the SL(601) with an angle of about 90 degrees from infinity to the minimum focus distance. I cannot set the behaviour of the lens on the SL(601) because there is no menu item for it. This menu item is on the S1r, as helged perfectly described above. For further testing I set the "focus ring control" to non linear with the SL-Summicron 50 mounted on the S1r and put the lens back on the SL(601), again. The focus throw was still linear on the SL(601), so I think that the lens does not remember the last setting from the S1r or any other camera but is always in linear focus throw mode on the SL(601). It might be that you loose the non linear mode with the SL(601) forever after the update and have the linear mode instead. I like the linear focus mode much more and the lens feels in this regard like a manual lens to me now. Â I have updated my SL 35, 24-90 & 90-280 via SL2 and all is working well. I still have my SL 601 as a second body, should I also be individually updating the FW on the SL 601with each lens as well? Seems SL 601 users are seeing and liking MF after the update.

Advertisement Posted January 2, 2021 Posted January 2, 2021 Hi MarkinVan, Take a look here SL Lenses firmware 2.0. I'm sure you'll find what you were looking for!
RoySmith Posted January 3, 2021 Share #82 Â Posted January 3, 2021 I updated my 24-90, but was disappointed there was no update for the 16-35 VE SL, or the 50 Summilux SL. Link to post Share on other sites More sharing options...

Do you observe linear focus throw with the SL601 and the SL35 as I observed it with my SL Summicrons 50 mm and 90 mm? Link to post Share on other sites More sharing options...

I don't know the details of these manual focus options well enough to fully understand the pre & post update characteristics and am focusing right now on setting up which setting I prefer for each of my 3 compatible lens. Once I find my preference with each lens on my SL2 it seems according to what I am hearing those setting will automatically carry over when used on the SL601. It all seems to be a good step forward.

jo kami Posted January 7, 2021 Share #85  Posted January 7, 2021 Can anyone confirm this firmware works for SL 601? I'm assuming since there is no option to change MF within the menu systems that it is pointless to upgrade for 601 users? Link to post Share on other sites More sharing options...

I used my SL 601 to update with the Version 2 firmware update. Put the lens firmware update file on the top level of a SD card. In the menu, go to Camera Information> Lens Firmware Version > Start Update  Link to post Share on other sites More sharing options...
Jim D Posted January 25, 2021 Share #87  Posted January 25, 2021 Advertisement (gone after registration) As of 1/24/21 - I applied the SL update v2.0 to my 24-90 lens and now works on my SL2. Super easy, no issues.  Just FYI. Link to post Share on other sites More sharing options...
BlueIn2Red Posted February 10, 2021 Share #88  Posted February 10, 2021 Can anybody guess why the 16-35 hasn't been "done"? It's the only SL lens I use manual focus a lot with (for landscapes)! Link to post Share on other sites More sharing options...

scott kirkpatrick Posted February 10, 2021 Share #90  Posted February 10, 2021 I have a theory that the 16-35 was developed with an external partner, so the information needed to make linear focus might not all be available. There was a patent issued to a Japanese company for a lens design that looks a lot like it. That is just speculation, but it might explain why Leica doesn't change the firmware from as it was issued.. 1 Link to post Share on other sites More sharing options...

Scott, this is true - but it‘s the same case for the 90-280 even with the same Japanese company. I suspect 16-35SL and Summilux-SL 50 are the two lenses with smalest turnover, so these will follow later (hopefully) Link to post Share on other sites More sharing options...
