The mirrorless camera evolution is about many things, but size is a big one (ha?) Putting a 24×18 or 36×24 sensor into a smaller body with less moving parts saves cubic inches, grams and potential breakdowns. And presumably costs are lower, but of course that's not easy to prove.
However: the size factor breaks down somewhat since lens size still has to match up with the camera sensor lest the corners of all your images go dark. Smaller sensors like 4:3 helps shrink the lenses - but then owners crave really fast glass to compensate for the smaller sensor size.. The 24×18 crowd want fast zooms with lots of great optics. The 36×24 say "where is my fast gear?" The lenses are only a bit smaller for mirrorless than for dSLR for the same sensor since the lens must send light to the entire sensor regardless of body type. And so smaller cameras (with small gripping areas) begin to spout large, unwieldy lenses requested by the users, especially at the telephoto end.
My NX300 is great for short zooms at the wide end or for fairly wide primes. My K-50 won't fit in any reasonable pocket even with a pancake prime. Step up to the K-1 and you must accept the bulk whatever lens you choose - it's half again the weight of the K-50 but the cubic inches will also be significant!
Looking at my current set of K-mount lenses, I am well covered in both 'FF' and APSc formats. So if the lottery funds flow our way it could be managed optically. As to physically, it would be a shock - but the NX300 could be the easy-shot camera when it came to distinctions.
- 36×24 "FF" primes = 28, 50, 135, 300, 400mm
- 36×24 "FF" zooms = 15-17mm fisheye*, 35-105/3.2-4, 80-200mm f/3.5, 100-300 (15-400mm)
- 24×18 APSc = 10-17 fisheye, 18-55WR, 55-300WR plus all the above (15-450mme + 600mme prime)
*10-17mm fisheye >15mm as shown on K-1 demo pages!
I swear I'm not actually planning to buy a K-1 any time in the future - but its features are enough to make me consider the benefits of strapping a massive camera to my chest. I honestly did not expect that, as even the K-3ii seems like a lot of camera. But everything that APSc flagship camera can do, the K-1 does better - and more features besides, many of which I find.. intriguing.
Below is a link to the specs, and a subset that highlights all the gee-whiz new-to-me features and improvements that my K-50 lacks.
