Says you. One should never speak in such absolutes when posting a personal opinion.
The image stabilization in the newer GoPro models alone is a good reason to consider a GoPro. It is truly amazing and more effective than anything else on the market at present.
Color is also pretty easy to correct in Post and you can even more accurately do what paralenz does with their in-camera software. Granted, you need to spend a little time doing that - but I would rather correct color rock solid footage than take the shake out of somewhat color-corrected footage.
For me, the screen is also essential as well - I want to frame my shots in real times. I don’t normally shoot wide: I use linear - so pointing in the general direction does not cut it for me!
No 4K 60 FPS on the paralenz either.
Individuals should do the research and determine what works best for their needs!
BTW - I’ve been diving for 5 years now and taken 4 dive trips this year (Caribbean and French Polynesia) and have yet to see a Paralenz - plenty of GoPros though!
I have over 25 years of underwater photo experience with all types of cameras diving all over the world from the challenging waters of New England/NY/NJ to the tropics. For action cameras (I use a housed DSLR for my dedicated professional photo work), I'd choose Paralenz for most work as I have pointed out above. I was going to buy the latest GoPro but after I saw the Paralenz and checked around and talked to Paralenz people in Denmark, it was no contest and decided on Paralenz, the best value out there.
