Panasonix gx1 vs entry level dslr

At the moment (in terms of current technology)...

DSLRs are better in terms of:

1. sensor size, and thus low ISO performance (though mirrorless is catching up)

2. PDAF, mainly the for high-speed/action photography, sports. (still a way to go for CDAF)

3. OVF, has infinite resolution, no refresh lag (but EVF is catching up).

4. abundant supply of third-party competition, which drive down lens prices. f2.8 constant zoom in Tamron/Sigma is way cheaper than Canikon

5. (marginally) grip, but mainly because of size / ergonomic designs

Mirrorless is better:

1. size, hands down (except the GH3 is a beast...)

2. weight, in terms of lenses, 500g for a 100-300 supertele (200-600 equiv), find that on a DSLR?

3. Great intercompatibility between olympus and panasonic lenses /accessories. So less lens buying when you switch systems... (unless you go for EOS-M / Nikon J1/V1, Pentax Q etc.)
