Adding another crop factor for 4K recording may not be a bad thing in the case of LX-8. For LX-7, we all struggle to find a good WA wet lens mainly because 24mm cause vignette, people still have to zoom in to 28 or 35mm to use certain wet lens anyway. I still have my Inon UFL-165AD, wonder if that works.
Intercepter121, you can get great 1080p from 4K footage, problem like moire would not be an issue (imagine being able to see the detail of the sea fan/grass). 4K also let you stabilize, crop, or have interesting composition. I can imagine just using a +5 diopter to shoot 4K, then during post, zoom in and make it look like a +10 diopter result when output to 1080p.
Still have no ideal when LX-8 will be announce, late August? September?
