I really cant understand the concept of the Sigma 13-35 f1.8 lens. Yes, it's bright. But for what situation it's good? For interior or architecture shots you want to use small aperture, you never...

It it's faster than previous model, I'm a taker.

There is no point of mad pixel race in the space. 2MP is more, than Your 24" LCD screen has. As we know, panorama photos will be stitched together. bear in mind scarce resource of Mars-Earth data...

Most probably You are not informed, that these firs images are just proof of landing. High res images, panoramic and color are coming later. Yesterday they actually rised the camera "tripod" and...

Is it as good as special-purpose phase-detection sensor? As fast and accurate?
Are the same pixels used later also to capture the image?

Please stop spamming Nikon in my thread.

Oh, that's ingenious. Interesting, that it's not widely used as phase detegtion is in worst case 2x faster (predicts focus direcion) than contrast.

Nikon 1 is another story, lets not dwell into it.

I see in specs that EOS M has both contrast- and phase detection focusing. How that phase detection is implemented in such small body, 18 mm from flange to sensor?

How the phase-detection focus is implementel? Like Sony? It's pretty hard to fit phase detection into ca 20 mm flange space.

How the phase-detection focus is implemented? Like Sony? It's pretty hard to fit phase detection into ca 20 mm flange space. Do they have phase system only with EF adapter?

Being honest, this Ply glass looks better than Leica DG 45mm "can" with such a small small front lens.

One differentiator for M43 is short flange distance, allowing to make small cameras with still large sensor. This zoom eliminates all that and does not make sense. I strongly prefer set of fix...
