DocBobo Posted February 19, 2020 Share #1 Â Posted February 19, 2020 Advertisement (gone after registration) I am been using both M mount and R mount lenses on my SL2. With the M mount lenses, the camera immediately magnifies when using the focus ring. For R mount, it doesn't. Am I doing anything wrong? Or this missing?

Advertisement Posted February 19, 2020 Posted February 19, 2020 Hi DocBobo, Take a look here No automatic magnification for R mount lenses. I'm sure you'll find what you were looking for!
digitalfx Posted February 19, 2020 Share #2 Â Posted February 19, 2020 are you sure your M lenses do this? Its not physically possible, as the non-native lenses are not coupled with the body. How would the camera know the lens is changing focus? For both you need to push the button on the front of the camera to enable this function. 1 Link to post Share on other sites More sharing options...

bags27 Posted February 19, 2020 Share #5 Â Posted February 19, 2020 (edited) Are you using Leica's adaptors or 3rd party? Edited February 19, 2020 by bags27 Link to post Share on other sites More sharing options...

bags27 Posted February 19, 2020 Share #7 Â Posted February 19, 2020 Advertisement (gone after registration) At least on my CL, Leica adaptors allow you to use the wheel for magnification; third party require you to use arrows. No big deal. Link to post Share on other sites More sharing options...
digitalfx Posted February 19, 2020 Share #8 Â Posted February 19, 2020 OP is asking about "automatic magnification for R mount lenses". It doesn't matter which adapters you are using in this case. 3 Link to post Share on other sites More sharing options...

No big deal. That is true, but this is about the SL... And not the question of the OP. No manual lens will ever be able to trigger automatic magnification. Although, maybe some very smart A.I. software in the camera in the future, who knows? 1 1 Link to post Share on other sites More sharing options...

Stonewall Brigade Posted February 20, 2020 Share #11  Posted February 20, 2020 Are you using the Leica R-to-L lens mount, or a generic lens mount (that won't transmit data between the camera and lens)?  Link to post Share on other sites More sharing options...
jaapv Posted February 20, 2020 Share #12 Â Posted February 20, 2020 The only data that can be transmitted are the content of the ROM. Basically the lens type for EXIF, that is all. Link to post Share on other sites More sharing options...
makiyo Posted February 21, 2020 Share #13  Posted February 21, 2020 Yes automatic magnification even not working on my SL2 with 18765 adapter and all my asph lenses.  i am sure I turned on the magnification in focus assistant Link to post Share on other sites More sharing options...

No manual lens will ever be able to trigger automatic magnification. Although, maybe some very smart A.I. software in the camera in the future, who knows? Indeed the SL does not auto magnify but, and perhaps this is the source of the OPs disappointment, the M certainly can be setup to auto magnify when the focus is adjusted. This is something I use all the time. Presumably there is a sensor on the RF mechanism that notices motion and triggers the magnification and of course, since the SL is not coupled to the mechanics of the lens in anyway, it can not mimic this behavior, though I'd agree it could perhaps be detected in software.  Frankly, what would be more useful IMO would be to enable the CD logic in MF mode such that when the software felt focus was achieved in the detection area, the box went green or indicated it in some way just as it does when in AF. The Pentax 645 D/Z does something similar whenever it is set to MF mode. The AF logic was kept active n MF mode and whenever one achieved focus in MF mode, it would flash a red light indicating it thought focus had been achieved. This was something that I found quite useful on occasion (and something I wish would be added the M as well though it some might find it odd to include CDAF logic in a MF-only camera).  Link to post Share on other sites More sharing options...
Exodies Posted February 21, 2020 Share #15 Â Posted February 21, 2020 (edited) Detecting manual focus changes by looking at the sensor is not possible. How to distinguish it from photographer or scene motion? Edited February 21, 2020 by Exodies 1 Link to post Share on other sites More sharing options...

Whether it's practical or not I cant say, but I wouldn't underestimate the power of ML, with enough sample data, to be able to detect a numeric difference between the two that we puny meat bag brains fail to discern. Link to post Share on other sites More sharing options...

My second objection is when would this algorithm run? While the camera is on? While your eye is at the viewfinder? It will need more battery. Link to post Share on other sites More sharing options...

This mechanical signal allows magnification to be switched on at the right time. 1 Link to post Share on other sites More sharing options...
