Re: [Leica] Why Metz flash is always at 70mm on 70-180mm lens

[Ben Ho ^_^ <longjohn@netvigator.com>]

Hello Pascal,

Thanks a lot for the information.  Now I know my len is working properly.

To a large extend, this info also reveals how wierd Leica is in developing and
updating it's product.  The less costly (but still very expensive) lens carry
the sensor, but the more expensive ones don't.  Do the guys in Leica know what
they are doing?  Very curious!  : (

Thanks again.

Best regards.
