The Leica M3 was a drastically modern design being bigger and bulkier than its front sprinter. With a new bayonet lens install taking over from the 39mm Leica screw thread, the range finder and viewfinder was now mixed. Two swings of the recently developed level breeze instead of switching a button intended the movie and shutter functions took place in one function. The M3 presented a top installed selenium-cell visibility gauge which was to be ongoing in principle for 50 years.
if you ordered Canon Vixia HF M40 less than a month ago, then you probably got it at a big discount. Most US suppliers were offering it for $399, which is $300 off the normal price. This was your "heads-up" that a new design was on the way.
