Motorola Moto G (2nd gen) £100
BIGGERSamsung Galaxy S5 (£350 ?)
BIGGERThe household is about to take delivery of a (too mind-boggling expensive for me) Galaxy S7 Edge. I'm interested to see what results that gives.
One thing is clear to me though. If you just want traditional 6x4 prints or images to simply display on another phone then the £100 Motorola Moto G is fantastically adequate as a camera. The differences only really start to emerge once you drill down and start pixel-peeping. a 10" Tablet starts to reveal the quality of the Samsung S5 camera.
For reference here is an image from a Canon S120 compact (albeit a >£400 compact when released).
It was set to a very wide 24mm, so it's not a perfect comparison.
BIGGERFor a well lit, wide-angle, scene, with no difficult lighting (high contrast or very flat) then you may as well reach for a phone as a camera. Certainly a simple, £100, Jpeg-only compact camera won't buy you much extra.
Add difficult lighting, or the need for nice portratits, then the RAW capability of a decent camera and optical zoom, are really needed to get something decent.
It would be an interesting challenge to do some portraits using a phone camera.
