All of you bring out the Micro 4/3 as an example to compare against APS-C sized sensor DSLR. You will have no disagreement from me or anyone that going to a smaller sensor size will reduce the weight and size of the gear. Mainly is the lens size that will be smaller and lighter. That is very obvious from looking at the numbers. Bigger sensor gathers more light and requires bigger lens. Just to be sure, micro 4/3 is a good format for some conditions, but there is low light compromise and less bokhe for those that want more subject isolation.

I want to keep the APS-C advantage, and that is when you run into questions of why switch to mirrorless. Looking at the graphs again, there are some weight savings, but not that much. Sony A6000 is the closest match to DSLR for focus speed, but the savings is only 60g when compared with Canon SL1. Little more at 1/3 lb when compared with Nikon 5300. Car key and a bunch of coins would be 1/3 lbs. Skip the extra large at McDonalds will save that much too.

Fujifilm X-T1 is a higher end camera. From reading reviews, Fjuifilm normally does not focus too well on moving objects, and certainly not as good as A6000. Is 440g compared with 750g or so for a Nikon D7100 or Canon 70D equivalent that can guarantee to focus on moving subjects. There is 3/4lb of savings there, but lens will be the same weight. Fujifilm does not have any fast zoom lens. For low light, you then need to carry multiple fast primes lens. 3/4lb savings is a moderate savings then if you are carrying multiple lens. Looking at it quickly, 18mm and 27mm lens are very light at under 100g. Beyond that, at higher zoom range, prime lens seems about the same as DSLR. If you mainly use wide angle prime, and don't need focus tracking Fujifilm would be good.

To me, the advantage is with Sony FF mirrorless.

I am mostly using the same lenses across systems and the A7 is the best fit for me for form and size.

Some M4/3 lenses do have a size advantage but the cameras mostly do not.

Then again, the biggest heaviest 300 2.8 lens is the one made for four thirds sensors.....the advantage in size is mostly due to using lenses at half the focal length of full frame for a similar angle of view.    I have had some very small FF lenses as small as my m4/3 ones.
