Would be pretty cool if they could bin pixels when needed to increase sensitivity.
Gothmoth: i hope it kills the overpriced EF 35mm f2.
The EF 35/f2 costs about £220. That's not that over-priced.
Small, a little noisy, but a very solid performer wide open already.
antiq: The first thing I will be interested in though is how accurate it focuses on Canon.. the only thing that Sigma was lacking in the recent models was consistent accuracy.
Focusing accuracy is always a function of both the body and the lens. There's a nice in-depth explanation somewhere on the lensrental.com blog.
AP7: Good news: Nice pricey camera with "Leaf Shutter" that can sync up to 1/2000 sec.
Bad news: In bright day light, the maximum aperture that you can use without blowing out background is f/3.5 at 1/2000sec and ISO 100 (according to Sunny 16 rule). The flash guide number is 6m. So, it can only cover 1.7m or 5.6ft. If you subject is 15ft away, it will be 3-stops under exposed. Therefore, it is not so useful for daytime fill flash. Why can't they put a flash with guide number 13m (available in most DSLR camera) at least or shutter speed 1/4000 sec to get full advantage of leaf shutter?
Even if the onboard flash is weak - leaf shutter!!! Finally sync your flashes past the 1/160 you frequently see on m4/3 or similarly sized cameras. Yeah!
