Lenses would still be big right???

Nope, it's a common misconception. Compare, for instance, 35-100/2 on 4/3 and the 70-200/4L IS on 35mm FF. The size of most lenses is determined by the amount of light they need to collect, the same amount light - the same size of the lenses, no matter what the sensor size is: http://www.josephjamesphotography.com/equivalence/#2

Except the fact that F4 is slow. The main reason for an F2.8 or faster aperture is to achieve faster shutter speeds. As someone who owns a 70-200/4 and 70-200/2.8 L, I can tell you there is a huge difference in size, and for many things that extra stop of light from the bigger lens is a godsend.

That's because you don't understand the laws of physics, that f/2 on m4/3 sized sensor is fully equivalent to f/4 on FF sensor -- you'll get identical pictures in both cases. Follow the link.

My day keeps getting better reading this thread.

Another equivalence adept that isn't getting it.

F2=F2=F2 and F4=F4=F4 You apparently didn't use the Olympus 35-100mm F2 lens.

We make photo's with light and not with DOF. An F2 lens is F2 on any format, people that understand don't use your argument. If they need shallower DOF than the y will buy or rent a 35mmFF for the purpose. However most that buy into m43, know why they want it.

Rules of photography haven't changed and external lightmeters keep on working regardless of format.

Don't mistake DOF properties with light properties.
