You have included an A-mount APS-C Sony lens which isn't designed for E-mount, the Sony 16-50/2.8. You could use this lens with an adapter on e-mount but it would be an exception to what most would purchase for mirrorless use. Just thought I would point this out. There isn't another fast zoom to replace what you selected in your analysis that I can think of unless you want to include the SEL1670Z which is a stabilized constant f/4 and 308 grams.

Yes, thanks for the catch. Sony 16-50 f2.8 is for alpha mount. Don't see any f2.8 midrange zoom lens. Too bad because f2.8 lens is the one I like to use most. Guess the reason Sony don't offer fast zoom lens is because the NEX camera is to cater to those who are weight/bulk conscious, therefore, Sony does not offer any fast zoom lens because they tend to be larger. For fast lens, you are forced to use prime lens. Find the same to be true for Sony full frame NEX camera. Sony does not offer any fast zoom lens.

So is a trade off, either bring a few prime lens for APS-C mirrorless or one fast zoom lens with DSLR.

You have to keep in mind that mirrorless systems are still very young. These systems are still growing. It's only a matter of time before there are a range of f/2.8 zooms for mirrorless. For example, Fuji is going to be releasing the XF 16-55mm f/2.8 R OIS WR and the XF 50-140mm f/2.8 R OIS WR soon for their mirrorless system:

Left to right: XF 18-135mm f/3.5-5.6 R OIS WR, XF 16-55mm f/2.8 R OIS WR, XF 50-140mm f/2.8 R OIS WR

They all have image stabilization, they are all weather sealed, and yes, these lenses are fairly compact compared to their DSLR equivalents. For example, a Canon 70-200/2.8L IS has a front filter diameter of 77mm, but the Fuji XF 50-140/2.8's filter diameter is only 67mm. From the looks if it, the Fuji XF 50-140/2.8 OIS looks like it will be the same size as the Canon 70-200/4L IS (yes, the Canon f/4 lens!) because the Fuji is specifically made for APS-C. Both these lenses have 67mm filter diameters. But the Fuji is f/2.8, while the Canon is only f/4. And the Fuji XF 16-55/2.8 looks like it will be a bit smaller than the Canon 17-55/2.8 EF-S. Both have 77mm filter diameters, but the Fuji lens appears to be shorter.

Canon 17-55/2.8

Fuji XF 16-55/2.8

Canon 70-200/4L

Fuji 50-140/2.8

So, all in all, I think you're being a bit naive and premature in assuming that mirrorless systems won't have fast zooms, and that mirrorless users will always be "forced to use prime lens". We're still in the very early days of mirrorless systems...especially compared to SLR/DSLR systems! Mirrorless systems need time to grow.

These lenses are big. As soon as you go over a certain size you get better ergonomics with the grip of a DSLR.
