Just a quick update after an hour or so of use. It's pretty good although I'm still using it on an iPhone. I really haven't spotted any glaring problems, but right now all the documentation seems to be on the company's website, and what's there seems to be incomplete and sparse. Hopefully they'll flesh it out a bit.
One thing I'd like to see (probably others I haven't found yet) is the ability to specify sensor size and aperture to get a more accurate idea of the depth of field. I know that it won't be perfect, but it would get the pre-viz a bit closer, and for me, more useful.
The number one thing needed though is better documentation.
I just bought it for my iPhone 6 (not the Plus), and it looks pretty good. I would suggest that if you're going to be doing a lot of work with you you use it on an iPad since the controls get pretty small on a phone, but it's still usable. Now I have an excuse to finally join the 21st Century and buy an iPad.
A polarizing filter could be a problem depending on the construction of the window. Invisible or semi-visible stress patterns in plastic or glass could be enhanced by the filter, as the stresses polarize the light.
Almost 10 feet diagonal and 8K, is that all?
I understand the valid concern of pilots who talk about potential and past problems with drones. The problem as I see it is that the law is too draconian and will result in fewer people becoming properly trained. With more unlicensed drone pilots doing their thing, it will be harder for the FAA to enforce. Now if they were to drop the requirements to a more realistic level, that might entice more people to actually become trained and licensed. Unlicensed violators will be easier to detect, and the FAA will have an easier time clamping down on those that violate the rules.
"...a process that requires dozens upon dozens of hours of training."
And thousands upon thousands of dollars in flight time with an instructor in a light plane. Let me officially go on record as saying "Fuck that shit." Someday I'd like to get my license (I've got 5.5 hours towards it, earned 30 years ago, big deal), but now is not the time.
