Also gigantic difference in native lens size, especially with regards to the zooms. That Sony 70-200 is 2.3x heavier than the Panny 35-100 as well. There is no free lunch.
But that isn\'t a fair comparison. The optical characteristics of the Panasonic 35-100 f/2.8 would be matched by a 70-200 f/5.6 zoom. One doesn\'t exist (at least yet) and if it did it would no be much bigger than the 35-100 f/2.8. The 70-200 f/2.8 has a lot shallower depth of field and that matters to a lot of folks and a major reason that a lot of people schlep along a f/2.8 70-200 when there are excellent f/4 7-200s around. Note I do not have a hate on for micro 4/3rds. I have an OM-D (Em-5) and I plan to keep it and I even plan to get the Panny 35-100, but I know what I am getting and it is not the same as a 70-200 f/2.8 on full frame. Instead it is a much smaller lens that makes some sacrifices (primarily more depth of field or less shallow depth of field).
