A few random thoughts/questions
Did the g5 face the same issues as the v20? It never seemed to catch on so not much written that ive found on the g5 camera/sensor.
The steady shot. Its odd that a feature thst wss a huge part of the marketing campaign, by most accounts, is better as completely ignored/turned off. The best we've heard so far is its ok when you are possibly walking. Poor planning by lg. So if halfway through the video you decide to stop walking, you get half a video that is steady with a second half that looks like an earthquake.
Now the g6. Curious if the camera will follow the g4/g5 path, or thr v20. Me personally... I'm still not sold on the whole wide angle thing simply because of the odd curvature you get around the edges of the photo. My personal opinion only... I would take one strong camera instead of two three or four gimmick cameras that aren't fully thought out.
I enjoyed the G5 and it's twin camera... In fact its one of the reasons I went with the V20.
My results with the V20 have actually been mostly positive. Occasionly I get a bad shot. Where I differ from most folks is that I use my phone as a camera for convenience to take snapshots. I'm not a real fan of using cell phones for photography. Yeah I know.... The best camera is the one you have with you.
Steady shot is not a cure all.... It is designed to assist in taking steady videos by compensating for hand movement. Its not perfect and certainly could be better on the V20. If you have very little hand movement you don't need it and it can actually be detrimental. That is the same reason photographers turn off image stabilization when using a tripod.
Curvature on wide angle lenses is normal even on high end lenses. That's just the nature of the beast. The fact that LG has a second camera feature has little to no impact on how strong the regular camera is but I get your point. The rest of industry is headed in the direction of multiple cameras if you are following any of the new model leaks by other companies so at this point it will be the new norm.
With regard to the V20: I'm hoping that some of the issues can be addressed through a software update but only time will tell.
