Leica Q2: high ISO shutter speed

I have read in various forums, that the Q and Q2 (in fact all Leica cameras) limit the maximum shutter speed for high ISO settings. I can't find any information about that in the manual.

What are the actual max shutter speeds for which ISO setting? And why is it restricted at all?

Edit: with "max shutter speed" I mean "longest exposure time". Sorry for any confusion.

From: https://www.l-camera-forum.com/topic/295219-left-disapointed-by-the-leica-q2-firmware-limitations/

"Leica seems to limit exposition time at higher ISO: ISO 6400 4s max - ISO 3200 4s max - ISO 1600 8s max - ISO 800 15s max - ISO 400, 30s max - ISO 200, 60s max, ISO 100 - 120s max, and ISO 60 - 50s. Going into T mode do not allow to override that limit."

I was looking for some official information, not just a shady rant. But thanks anyways 👍

Leica's statement:

And here's an attempt to explain in more detail...

The reason for maximum exposure times

According to Leica Camera AG, these limits have been set to prevent uncorrectable imaging errors caused by longer exposure times.

So what does that mean?

The ISO sensitivity values in digital cameras are increased by applying signal gain. An algorithm amplifies the signal, and the better the algorithm is, the more accurate a tone and color is even when a 200 ISO sensor sees it in dark. The software algorithm makes it pretend the sensor sees better in dark than it actually does. When it doesn't work it is called noise.

Unfortunately this process of either higher ISO and/or longer exposure time amplifies not only the signal, but also the noise of every image.

My take:

Leica feels that longer exposures at higher ISO settings result in unacceptable image quality degradation and so they prevent their cameras from operating at these settings. It's their version of "You're doing it wrong."

Thanks!

The correct quote is "you're holding it wrong", btw

And that wasn't even a real quote.

During the iPhone 4 "antenna gate" fake scandal. Steve Jobs held a press event where he methodically explained what caused the issue, and demonstrated that it was evident in every popular smartphone available at the time. He also revealed that the return rate for the 4 was far lower than the already low rate for its predecessor, further reinforcing the inference that it was a fake scandal propagated by Apple haters with the help of the media.

Tl;dr, He never said people were holding it wrong. He said that all phones suffered the same issue depending on how you held them.
