Compact camera vs iPhone

Hi,

I am in the market for a replacement of a 10 old compact Canon that I flooded. I am not willing to bring my full frame camera underwater, mostly because of the volume and weight for air travel. The 2 options I am considering are (1) a new compact camera and housing like Canon G7X and (2) a camera housing for my iPhone 12. In both cases I would mount them on a small tray with lights. I have a GoPro already and don’t consider it as an alternative given the still image quality is poor and it’s hard to properly shoot given the small screen.

How would you compare the 2 in terms of image quality (video and still) and ease of use? 

Thank you!

The SeaLife iPhone housings have become very popular with folks who use the dive operator I dive with in Sint Maarten. They are almost taking over from GoPros. With a relatively small light attached, they are easy to use and easy to travel with. Image quality is good. 

The big difference though is in their flexibility and control. With the Canon G systems there is a good level of control over aperture, ISO, shutter speed and strobe use. This is way more limited with an iPhone housing. 

I’d suggest herein lies the choice. If you’re looking just to take snaps of what you see underwater, the iPhones are amazing.  But if you want a more creative approach with the ability to vary camera controls and lighting to produce specific effects and outcomes, the Canon type systems are clear winners.
