It is difficult to know exactly when the shift from gelatine to agar occurred. As often happens for scientific breakthroughs, agar was likely adopted incrementally alongside the use of other growth media. In 1913, for example, the first diagnosis of Serratia marcescens as a human pathogen was made by growing it on agar as well as on potatoes.
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.
