Any Die-Hard Canon fans switch over to Sony? Hobbyist photographer here. I have about 10k in canon equipment (5D Mark III/6D 70-200 f2.8 III, 16-35L F/4, 50L 1.2, 85L 1.4) to name a few.

I usually shoot for portraits, landscapes and urban.

Recently I have found myself being weighed down by my equipment. My bag usually consists of a 5d mark III, 70-200 f2.8 III (this is the first one to go when considering weight, and the heaviest of the bunch), as well as a carbon fiber tripod and 16-35L f/4 and 50mm 1.8.

I do a lot of weekend trips and even this light-weight setup can get heavy after a full day. 

I have always been die hard canon (mainly because of all the glass I have) but it seems Sony is really stepping up their game with the A9. Switching platforms would be expensive, but the weight difference I think would be substantial.
