The DP series has smallish batteries: 3.6V, 1250 mAh, 4.5Wh Don't know how they managed to empty them faster than one can charge. The Quattro batteries are double size and come with 7.2 V, 1200 mAh and 8.7 Wh. The new BP51 is a bit bigger than the Quattro's but it has to serve an EVF, LCD and second LCD for the camera data. Again: The DP series is about 5 years or even older - taking them as sample for prejudices about battery life or AF speed might turn out wrong.

 

I didn't check the body dimensions, I just saw the 35/1.4 in front of it and it made the camera look "normal", but seeing the hand at the grip, it is pretty high.







 

 

The depth of it is due to the flange distance which is the same as Canon, I think. About 1.5 cm is finder, maybe 3 or 3.5 real camera and the rest of the 9 cm is the tube. As you could see, reducing the tube and developing an entirely new mount would not gain much size reduction unless you do it at the cost of the grip. Just to add a genuine or third party grip? The idea "mirrorless has to be smaller than DSLR" is leading the wrong path. At the end a manufacturer needs to develop a whole new line of mirrorless lenses. I can see the point if the body is already small, but high performance AF lenses don't come all as pancakes.



 

Wherever you got the idea from it's only for FF lenses, I just don't think it's true. The sd quattro without H is just an ordinary APS-C size camera - enough lenses around for that. The H version maybe needs FF lenses but even if so - so what? I just wait to get more information, right now I think Sigma did the right thing with those two bodies. And again, they developed more things than only a mirriorless body:

 



 

Yes, that's a dock for their flash to update firmware.

 

But it is no compact system - for me it has not to be, I see the Sigmas more as small medium format cameras. Resolution wise, even with a grin towards Sigma's equivalence maths, it comes close to a Pentax 645. My D810 has more than 1kg without lens, but ready to snap. And without battery grip which adds another 350 gr.

 

Not your cup of tea, stick with your great Canon and legacy lenses as long as you like the results. (Note: This is in no way meant cynical or sarcastic)
