I am greatly enjoying using the Leica M10. For me, it is the nicest handling digital M yet. I like taking wide-angle shots at vintage and classic car shows with some of my favourite lenses such as the 16-18-21mm Wide Angle Tri-Elmar (WATE) and the 24mm Elmar. At the recent Irish Classic and Vintage Motor Show I gave both of these lenses an outing on the M10. I tested both lenses in advance with the 'Frankenfinder' optical multi-finder and 'Visoflex' EVF for the M10 and I decided to go with the optical finder as the frame-lines enabled framing to avoid too many other spectators getting in the photos. My favourite combination was, in fact, the 24mm Elmar with the optical finder which has a setting for 24mm lenses. I like the EVF, but I prefer rangefinder focussing and also the use of frame-lines for wide-angle shots, so the EVF stayed in the bag for the car show.
An article showing some photos taken with the M10 at the car show is here:

I would be interested to hear from anyone who has used the WATE or 24mm Elmar with either the 'Frankenfinder' or the EVF on the M10.
