I'd think so. Any phone from this year, with the exception of the ultra budget sub-$200 phones, should be able to outperform anything from 2 years ago like the S5.
The camera is pretty decent on the Z Play. Daylight shots are sharp and have good saturation and dynamic range with HDR on. Even low light photos turn out pretty good as long as you have a steady hand. The only cons I see are the slow HDR processing and slow shutter speed in low light, both exacerbated by the lack of OIS.
As for video, you get 4K but are capped at 30fps for 1080p video. Audio is good, and the camera finds focus quickly since it uses laser and phase detection. Moto's software stabilization is some of the best in the business, so videos aren't shaky at all.
