Benefits of a dual camera?

[jamielov]

Still love what my g4 camera is capable of. Hands down my favorite camera of all the phones I've owned. The rumored/pretty much confirmed g5 is going to have a dual camera on the back, so my question is what does a dual camera accomplish? Is this a step forward in the camera department?

When the g4 was getting pre-release hype, the focus def was on the camera quality. The g5 doesn't seem to be giving off that same buzz as of yet. So ive been curious what difference a dual camera makes, or if it is just a passing gimmick.

Well.. depends on what the dual camera is being used for.... HTC did a dual camera, to allow selectable focus and bokeh effects. The problem with that is it is a limited application (and in the case of bokeh, can be replicated via software). It's wasn't really something people had such huge demand for.

Another application, one that I think might garnish a bit more interest, is true optical zoom, noise reduction and increased low-light capabilities. Phones have extremely tight packaging demands, so a large sensor fronted by a big lens isn't exactly the most attractive option. But a lot of the benefits can be had if a system can be designed around two (or more) compact sensor/lens systems. It's the same concept that astronomers use for VLA telescope systems.... string a bunch of smaller telescopes together and you end up with the equivalent of a massive single telescope.

3D imagery?

I sort of put 3D imaging in the 'gimmick' category. I mean, my kids' Nintendo 3DS have dual cameras that can take 3D photos... they are absolute trash cameras, but they do 3D.

That whole "gimmick" angle really has me wondering if the g5 is even going to be an improvement, or even worse, a step back from the g4 camera

I think LG is looking to improve the camera quality, not add gimmicks. I'm fairly confident it'll be better, but incrementally so. It's not like the current cameras are lacking.

Check out a video review for the Honor 6 Plus and you'll see how it works. You can get great HDR effects, post-processing refocus etc.
