I tried the 19mm Sigma on a GX1 and wasn't too impressed. It's a decent value, but IMO, too much distortion and a bit bulky. I'd rather get one great lens than 2 good lenses. The 20/1.7 is a great lens. Plus, f1.7 is a whole stop faster, and on a smalller sensor it makes for a big difference in DOF and bokeh. Also, it's much better optically, and about half the size of the Sigmas. The only thing better on the Sigmas is the AF speed. Other than that, the 20/1.7 has always been a stellar and highly reputable lens.

If you find distortion, it is easily corrected using LR, there are very few M4/3 lenses profile in my version (3.6) but all the Sigma`s are covered, not that I have ever seen much in the way of distortion with this lens.

Sigma 19 and 30mm LR lens profiles

I find the 19mm surprisingly good optically, sure its a stop slower, but with these new sensors its not going to make a whole load of real world difference.

And the size, yes its bigger than the 20mm pancake, its not really a bad thing, on the very small bodies this lens will give you added support (more to hold on to) and fitted to a GH3 or OMD with grip there are very few real advantages fitting a pancake.

The 19mm also comes with a fitted case and a hood, almost unbelievable considering the low cost of this outfit.

Edit if it was me I would be looking at the new 60mm in place of the 30mm
