this qualifies as abuse? geesh. I hate to break it to some of you white gloves guys, but this is just USE and average USE at that. I have had positively no choice but to leave an array of vintage cameras locked in a car in the low desert for weeks at a time over several points in my career and have never had anything as extreme as lens seperation or frankly, ANYTHING happen to any lens because of heat.
I am sure in a labratory, writing a warranty, this seems like a real bad idea, but if you shoot in the desert, its really just unavoidable. How many lens seperation cases are coming back from Iraq, or have in the last five years. Because you know, there are like NO cameras there...
Ive never had any troubles with any of my leica lenses in heat, but if leica quality can not stand up to heat exposure in a car, its kinda not really quality worth bragging about imo. How many of Larry Burrows or Henri Huets lenses seperated in Vietnam before they died? Neither of them did tons and tons of work in the north and the continental hotel did not have air conditioning...
Im sorry, that statement is just a little silly. It is common knowledge that a large batch of canadian lenses seperate. Its not because of design...
