Unresponsive AF

No.

 

Odd issues like this usually get blamed on SD cards ....... but that opens another can of worms.....  and a thread that may run for months ......

Interestingly I was advised by a Leica technician in their Mayfair store not to use UHC-II cards in my SL. They have an extra set of pins in their connection designed specifically for video and apparently the SL doesn't have a connector for them so UHC-II cards are completely redundant in the SL and can cause software glitches.

you mean UHS-II cards ?

somewhat bizarre advice as the SL has a dedicated UHS II slot .......

 

they do however only recommend a limited list of compatible UHS II cards compared to 'any' UHS I card.

 

I've only ever used Sandisk Extreme Pro UHS II16gb from day one with the SL and never had any issues I could attribute to card glitches.

i rarely go above 64gb...i sometimes have doubts whether the processors on these cameras can actually address 256gb/512gb memory storage..

 

16gb/32gb seems quite snappy and "safe"...this problem you encountered could be because of the system waking up from sleep mode...try a longer setting ?

 

 

Using "SanDisk Extreme PRO 256 GB SDXC Memory Card up to 95 MB/s, Class 10, U3, V30" for what it's worth

Do you ever find the SL completely unresponsive to AF?

 

I'm not sure if it's after coming out of sleep mode, but I have found the shutter button / back button to do nothing for 5+ seconds before springing into life.

Start-up and Sleep Mode times seem almost identical on the SL so I suspect 'Sleep' is what it says ..... an electronic 'Auto Power Off' rather than some halfway asleep position. 

 

Initiation results in 'Card Search' ...... probably some card integrity/memory check ....... checking the lens type and initiating the profiles and AF firmware etc. 

 

Any delay suggests the camera is doing something related to these processes  ...... poor SD contacts, memory integrity issues, poor lens contacts etc are possible physical causes......

 

As there are multiple possible setting combinations on the SL there could be a firmware bug that only occurs under quite rare circumstances resulting in it being stuck in a loop till timed out. 

 

Working out what is going on with intermittent problems is almost impossible unless a definite pattern appears .....

wonder if the SL does sensor cleaning after every sleep-awake cycle as well ? that's a straight 1.5 - 2 secs

Do you never check the information "you get" if it is plausible, before repeating it in a "public" place ?

This sentence is full of nonsense - I hardly know where to start.

 

The SL offers support for UHS-I and UHS-II cards - UHC is not existing.

Only slot 1 is for UHS-II (the faster cards). Both slots for the slower cards.

UHS-II cards offer at least 30 MB/s write speed which is necessary for 4k video. If you do no video, usually the UHS-I cards are fast enough. But the UHS-II cards are slightly better - and now after the firmware upgrade the speed of the camera (writing) is probably improved. So it could be worthwhile to make a small test of the current speed of UHS-II cards.

And no card has ever caused software glitches for me - maybe for others, but only on very rare occasions. If there were a lot, then there would exist a long list full of warnings.

Have you check whether the lens is fixed properly to the SL ?  It happens to me on a number of occasions on my first expedition with the SL ?

I will see if I can recreate the issue now, and I have confirmed the lens is on properly, turned it on and AF was usable as soon as I saw the display appear.

 

I will let it go to sleep and try later.

 

-- it had a short sleep timer, it worked fine.

 

I will consider it next time, if it happens again.

For someone who didn't know where to start I think you handled that really well.

 

I check the things that are important to me. This wasn't really that and as I said, I was merely relaying what was said to me by a Leica technician in their Mayfair store.

Glad it worked. Not a card issue here
