Camera equipment crossroads?

But ThBut whenext the ese commentslI may may changeve camera equipment.  I need to buy something now.  But what?

Here are some fact that may lead me to make a bold decision on my next purchase(s).

• I really do noTheset like lugging around well over a kilogram of camera equipment.  My Tokina 11-16mm is a great lens, but it is really heavy.
• When I have been able to use Marty's L-quality lenses, my impression is split: These things make great images but are really (REALLY) heavy.
• There are much lighter cameras and lenses available that record excellent images.

Let's see some numbers on comparable Canon APS-C and the top end of the Micro Four-Thirds world.

Item	Mass	DxOMark	DxO Score
Canon 7D	816		66
Tokina ATX-Pro 11-16mm f/2.8 DX	550	12
Canon EF 50mm f/1.4 USM	290	19
Canon EF 100mm f/2.8L Macro IS USM	625	18
Total	2281	49
Olympus OM-D E-M1	497		73
Panasonic Lumix G Vario 7-14mm F4 ASPH	300	19
Panasonic Leica Summilux DG 25mm F1.4	200	24
Olympus M.ZUIKO ED 60mm F2.8 Macro	185	21
Total	1182	64

(Masses, in grams, are from B and H.  The DxOMark scores are for the Canon lens on my camera; the Four-Thirds lens scores are from the Olympus PEN-5, which should be similar to the new OM-D E-M1.)

It looks to me that I could get sharper pictures and carry around half the weight by trading in my Canon stuff for this Micro Four-Thirds set.

You can get better DxOMark numbers from the lenses, to be sure, when they are on a Canon Full-Frame camera (5D Mark III), but it is even heavier.

Addendum, 6/5/14

These comments are no longer valid for me. I am committed to the heavy Canon equipment for now. 

But when the next EOS M comes out, ...
