50mm is always the answer and in the case of the lumix 1.8 it's even a really good one :-D

Other than a plain lipo batterys for my fpv quads without electronic safetys i never saw a battery swell and/or explode. It happens, but very rarely.

For the S5 i use Baxxtar batteries. No problems yet. Capacity wise I'd rate them about the same as the original battery that came with the camera.

The 105 is my sharpest lens. Not that i only have crap lenses, but because is is just that good. Beware of the focus motors though. In a macro they have to move things further and they are slow. ...

I think the bokeh is actually quite nice. Sigma 100-400 on Lumix S5 If you really need more than the 6 fps, you can always use 6k photo and have an insane burst of 30 fps and still 18MP to work with.

28-70 2.8 SIgma

The jpg is what you see in the review. The better the jpg, the better you can judge your shots.

I also have the 24-70 2.8 and i think there is a revised version of the lens because i never had any trouble with dust inside - but i know a lot of people have. Maybe Sigma changed something or ...

The Sigma 14-24 2.8 checks every box but lightweight. Awesome lens.

Same for me. Sigma 24-70 2.8 and 14-24 2.8 - i hope the 70-200 will appear in the near future.

That's a different lens, mate. OP asked for the 28-70 2.8. The 24-70 2.8 is indeed very nice, i use it a ton. But it is much heavier than the 28-70.

S5 only on the gimbal (weebill S) and ususally when i fiddle with the cables.

Firmware is not available anymore.

I am okay with afc on this one. I even use it for stills (Backbutton focus). Occasionally there's some pumping but i'd say it is not noticeable slower than the panaleica 50-200. Then again i ...

Can't tell you much about the Pana zooms since i only have the 20-60 (which you shouldn't dismiss as a crappy kit-lens, it's actually quite nice) But since i come from the G9 with the 50-200 i had ...

I use it mostly with the S5.

Same here. And that is not the case because i don't use it much. Most used lens for me.

I just leave my gear in the bag for some hours until it is approximately at room temperature.

Maybe the eye sensor af?

100% agree. That's one thing they should keep in mind for a successor.
