I just have to praise the micro43 system!....

There is much to be said for a bridge camera for the price of a good zoom lens. I had thought of it myself but bought a Panasonic 100-300 instead, which is probably my least used lens, although useful at times. My most used lenses are the 10x zoom on both M4/3 and A7. The Sony lens alone feels as if it weighs more the the E-M10 and 14-140.

Two areas where I find the Sony better. Dynamic range and low light-high iso without flash. There’s the fabulous focus system as well of course. To offset those there is the weight and lens size difference and the loss of features like in-camera panoramic, live composite and in-camera raw editing, 4k photo modes and other features, depending on brand and model. If I wasn’t so much into photography and the equipment that makes it possible, and was less able to afford it, the Sony full frame would never have been bought. No regrets though, because each has its place and I love learning and using them all. Got enough learning to do now to last me until at least the next five years, probably longer.

I didn't like the 100-300. Sold it.

Bought the Panasonic 100-400 which has fabulous image quality but is a bear to use on a small micro43 camera - heavy and unbalanced on my bodies. I have thought of selling it many times, but its IQ just makes me keep it.

The manual focus ring is too stiff on the 100-300 but for the rare time I use it, it does the job. Certainly instead of either a Panasonic 1000 or Sony rx10. 
I would probably use the longer focal length more often if it was on a bridge camera, but for 600mm+ equivalent focal length, the bridge camera would be a small sensor type.
