"Com[act, Light Weight, SYSTEM" that is a contradiction of terms. Most people have at least 3 lenses in their bag as a system. The size and weight of the body becomes secondary.The weight and the size of the bag will not be light or small. I would put is in a different way."We need a smaller lighter weight single lens combo" As a DSLR user, once awhile I do "travel light" with only a 18-55 IS kid lens on my 40D. I probably will get the 40mm f 2.8 to make it even lighter and smaller. As for mirrorless body, they are too small and a little bit too light for my shooting habit. Even the Rebel is too small in my hand.
Looking forward to it. On any DSLR body, such as my non gripped 5DMKII, it should make for a super light package.
It's interesting to see how many full-fledged dslr users suddenly speak out their desire to have a more compact, lighter camera system for some occasions. Imho this points towards the future - once mirrorless, more compact systems get a premium image, competitive af & lens selection, the old-school dlsr line will be less attractive.
No it's not. My present DSLR minimal system weighs a ton and threatens people when I take a shot. People look at my 24-105 on a non-gripped 5DMKII and I often get comments like 'that is a real camera'. Compare to my Fuji X100 with flash, batteries, hood and cards which all goes into a Black Rapid case over the shoulder. I never notice the weight or size, and people never notice when I'm shooting. Two systems, two purposes. But I have twice as much trouble to manage, batteries, cards to upload, dates and time settings to keep in sync, systems to learn ...
I'm now looking at the possibility of a system consisting of a 5DMKII and a couple of pancakes. If I'm feeling ambitious maybe a flash. The whole thing can fit in a small bag at a pound or two. And I've got nearly the IQ of the full system, and all the speed and convenience of one core component.
I don't know why this concept is so difficult.
