[quote name='popo' timestamp='1309000080' post='9515']The existing systems like NEX and m4/3 give us a relatively big sensor, and with that comes relatively big lenses in most cases. Yes, there is a bit of reduction possible due to the shorter mount distance, but if you want a long zoom, it'll be comparable to a SLR lens.[/quote]



That´s simply wrong. The long Pana and Oly tele zooms compare actually very well in terms of weight and size to DSLR lenses. To help you out with the facts:



Panasonic 100-300: 520 g

Olympus 75-300: 430 g

Nikon 80-400: 1340 g

Canon 100-400: 1360 g

Tokina 80-400: 1020 g

Sigma 120-400: 1750 g

Tamron 200-500: 1237 g



A mFT cam plus tele zoom with 600 mm reach weighs roughly as much (or little) as a mid-range DSLR body (Canon 7D, Nikon 300s) only... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='' />
