Yes. Herr Michl comes in two sizes. For big DSLRs like the Canon 5D, Nikon D800, ...) we recommend using the standard size bag.
For example we (Marie & Michael) are using the standard size with a Canon 5D Mark III and the large Canon 35mm 1.2L lens.
Yes! A smaller lens can be packed behind the outside zipper.
If you want to bring some additional stuff with you, we would recommend the standard size. Otherwise the small size works perfectly for you.
