The drawback to the Sofort 2 is that it’s twice the price of the Evo. It’s challenging to recommend at $399, as most people would likely consider the differences between the two cameras relatively minor. The Leica user interface is easier to navigate, though, and I appreciate the included lens cap and extended two-year warranty. I also appreciate that it lets you print photos taken with other Leica cameras via the companion app — a nice perk for Leica fans. Nonetheless, I don’t think those perks are enough to justify spending nearly $200 more.
