Experiences with ultra wide zoom lenses?

[jase]

I do mostly run&gun stuff and would like to emulate a gopro but without having too much fisheye and having a better image quality - therefore i am looking for an ultra wide zoom lens. I got a pana gm1 / sony a6000 body so there are plenty of options.

after some research i found the sigma 10-20 3.5 which would fit my a6000 since i got the ef adapter anyway. 

Anyone having amy experience with that lens or any other uw zoom?

If you want fisheye look, but less distortion, maybe a fixed lens and some tweaking in post (with a lens correction plug-in) could be the ticket! I would get something in the 8mm to 14mm for that if you are on APS-C. I say a fixed lens so correction is always the same and you have a cookie cutting solution. If you get the 10-20, you can experiment more looks (and more corrections!).

Actually i meant thr other way round: being very wide without getting the fisheye look

samyang 12mm f2 is a great lens if a prime is an option, its native e mount, really small and super sharp even at f2

I know, that is why I recomend you to experiment with a "lens correction" plug-in!
