there is now a great number of alternatives for a serious photographer wishing to have a smallish camera and lenses. some are fixed, some lenses are interchangeable. The lens sets are slowly getting more complete and so for somebody wishing for an ultrawide prime, wide prime, a standard prime and a moderate telephoto as options there now several options and more seem to be coming. Perhaps in 5 years or so when I may go for one of these wonders the dust will settle and it will be clearer which way to go. For now, I will lug Nikon DSLR and a clutch of lenses

Pavel: I agree that the ideal lenses for use on all of these marvels is a small set of primes. As I currently really only shoot with a 28mm and a 50mm, that works for me. Currently, the mirrorless products can't really go head-to-head with DSLRs functionally. In 5 years, the differences may not be so obvious.
