What's the point of a small camera with a humungous lens like that? IMO it's what's called a self-defeating behavior.
Why? I thought the point of a good camera body was to fit good lenses and make photographs. The best lenses to cover 24x36mm format simply tend to be bulkier than pocketable camera lenses. Particularly mid-range zooms.
I often don't understand the assumptions and expectations on these forums. The Sony A7/A7r bodies are not particularly small, they're similar in size to a standard 35mm film camera (Olympus OM-1, Nikon FM, Leica M4-2, M9). Lenses which are best for digital sensors tend to be larger than lenses designed for film cameras.
These Sonys may be the smallest FF, interchangeable lens digital bodies yet on the market, but they're still not small cameras. To me, the FF DSLRs on the market (and frankly most of the top end Nikons and Canons since the auto-focus, motor-film drive generation took over) are bloated monstrosities, which is why I refused to buy one.
I suspect that many have simply forgotten the lithe, svelte thing that a Nikon FM2n, Pentax MX, Minolta XD-11, or Olympus OM-4 actually was. Even the "big" Leicaflex SL or Nikon F/F2/F3 don't seem so big once you were swinging an F4s, F5, or F6 around for a while.
The A7 and the lenses I use on it remind me so much of my favorite Nikon FM and F3 from ye olde daze ...
