But how exactly you know this? And Why then Leica doesn't rate the lenses as weather sealed? Something has to give.Well the tight tolerances and lubrication in Leica lenses means that any water ingress will be very very small - nothing like enough to get into the camera through the lens mount.
No, it's not spurious. There's a reason why weather resistant or sealed equipment is advertised as such, and why equipment that it's not, it's not advertised as such. Remember also factors like increased humidity, etc.This is spurious Ricardo
The question is - can you shoot it in the pouring rain without screwing the electronics.
. . . and if you live in the UK this is a deeply relevant point.
No, what I am talking about is there is a distinctive category and reason why companies advertise and tell you their equipment is weather sealed. Those who are not, will be at a disadvantage, I am not talking about what you just said in the paragraph above.M9 - no
M(240) - yes
E-M1 - yes
GX7 - no
If you're thinking of life expectancy, then you better keep your camera at a constant temperature in a dust free environment with carefully controlled humidity - wear and tear is a different issue altogether.
That being the case, I have read no less than two reviews that mention shooting with a Fuji X100s in pouring rain and "the camera worked fine after wards." How much confidence that really inspires, to do exactly that when Fujifilm does not rate their camera accordingly?
Now if Leica tells you "hey, don't worry with the M, the lenses are designed to take it" that's another matter.
Here's another one-when I was in highschool there was an entire computer center of IBM PCJrs in a basement that goat soaked due to a major water leak in the room above. The computers were cleaned, we waited two weeks and voila. they worked! Weather resistant much?
No, not really. They started to fail (with different issues and varying degrees of frequency) within the first year after the event. Some of the components are more impervious to waters, others start getting oxidized, etc.
It's basically a dice roll, it's all I am saying.
