Anyone figure out why the 240 freezes up?

That sounds more like a cold-battery glitch.

 

Poor batteries, out in the cold !? No wonder our cameras freeze !

I suppose Leica will be offering the mini leather* coat accessory for our batteries. So warm !

 

*Get the Black Friday python special edition for just $999.99.

They do. It is called a (half) case, many third party suppliers do so as well.

If you want to keep your batteries above zero, just keep a spare in your pocket, although Luigi does nice leather battery cases to clip onto your strap.

Thanks, but I am not a fashion geek :rolleyes:

I had no issues whatsoever with my Canon batteries and cameras down to -15 C (never gone lower, but it should not be a problem).

Therefore I am convinced that this "cold battery glitch" is yet another excuse.

Because they are big lumpy heat sinks with nice plastic and rubber,,,

 

Nah... my Canon cameras are both magnesium alloy and much more power efficient than the M, considering their processor is about one order of magnitude faster than the ancient Maestro.

They have just been designed by people who know their job.

My camera crashed once again randomly during vacation (once in 3000 pictures) - Leica needs to solve this issue, we need new, proper firmware!

 

They bought the ASIC off-the-shelf from Fujitsu, instead of designing a custom one according to their needs - cheap but inefficient and highly problematic. Hope they kept their promise with the Maestro 2 and adapted more than just the name...

I don't really have any interest in this (don't own an M240) but I am intrigued by the expression and importance of 'one order of magnitude'.

 

Also, I am wondering if you are implying that the Leica designers don't 'know their job'.

 

And also, when did the Maestro become ancient?

 

Sorry about the three questions, which are probably not relevant, but I have an inquiring mind.

Moore's law - Wikipedia, the free encyclopedia

 

Advances in computer chips are driven by Moore's law.

So approximately every 18 to 24 months or so the number of transistors in a chip has doubled. That seems to be slowing down somewhat nowadays.

Lately chip speeds haven't increased a lot.

However, processing speed has still increased through exploitation of more parallelism.

So, the older a chip design is the more it has fallen behind the newest generation.

Umm... The Maestro chip was developed from the Milbeaut in a cooperation between Leica and Fujitsu.K-H is right, it is indeed time for the second version. Five years is about par for the course in camera processors.

So Canon has repealed the laws of physics? Li-Ion battery technology is rather universal, you know. As it gets colder, they go into hibernation, that is all. Get a small camera where the battery is squashed up to the bodyshell, it will heat faster so it will stop earlier, get a bulky one, you can get isolating air around it, rubber on the grip and a thicker plastic holder and it will keep up longer. As simple as that... It may come as a surprise to you that not everything on this planet translates into silicon...

However, read the manuals: no camera maker guarantees the functioning below zero (C.)

I'm mostly an observer here as I had exactly one lock up

In 18 months.

 

It is quite clear that CheshireCat (CC) is implying that Leica designers don't know their job. Perhaps he can offer some specific ways to fix or at least a methodology that would identify the cause of lockups. Perhaps it is not even firmware but some obscure hardware component that is susceptible in some cameras (or all) to some of the conditions noted as present during lockups. I don't really see the point of saying over and over ad nauseum that the Leica engineers are incompetent. Maybe CC should take the problem on as a consultant to Leica since he appears to have some expertise in the field. If he fixes the problem or even identifies a way to find the source, I would vote to bestow upon him The Order of Magnitude with oak leaf cluster.

Canon hardware of comparable price is about one order of magnitude faster. This is because the chip used is much faster and has more ASIC subsystems to accelerate specific image and video processing.

Of course, good software engineering helps a lot.

Power on lag is virtually absent. No long blackouts when shooting Live View. No Live View lags. You virtually never wait for the camera to flush the buffer to card. In-camera image review and inspection is instantaneous. You can shoot up to 14 fps (some people even make 14fps movies at full sensor resolution). You get full lens correction and advanced denoise at high-iso. You can capture 1080p@30 movies in H.264, not ancient MJPEG. And to be fair, I won't mention the AF subsystem that has its own dedicated processor driven by firmware that alone is more complex than the entire M firmware.

 

Also, I am wondering if you are implying that the Leica designers don't 'know their job'.

 

I am implying that from the fact the camera does not properly work years after launch. But it is just an assumption. It may well be that the Leica software engineering team is composed of just 2 great engineers that perfectly know their job. In that case, the team is understaffed, and I must assume some managers don't know their job. But it is just an assumption. It may well be that all 1000 great software enginees at Leica have been seriously infected by some sort of intestinal bacteria for two years, and productivity has dramatically decreased. But it is just an assumption. In that case, the doctor doesn't know his job ;)

 

The only fact is that my camera is not working properly after 2 years and I am not happy.

 

And also, when did the Maestro become ancient?

 

Before the M was launched.

The Maestro chip used in the M has the same specs of Fujitsu chips released in 2008 to serve low-end P&S and DSLR. The M was launched in 2012, with a 4 years old chip.

The chip uses a custom CPU and DSP, and this prevents programmers from leveraging the large amount of optimized libraries and development tools that are available for chips based on ARM, the de-facto standard CPU for small low-power-consumption devices. Hence increased development times and more bugs.

The lack of H.264 compression and the limited video capture resolution and framerate are a clear indicator of the chip era.

No, I am just saying it is not the battery that is causing the lockup ! :rolleyes:

The poster mentioned it was cold and there was no red LED...

You should be happy. I gave you a third type of lockup to rant about...
