The image quality of the 16mm is incredible, but I would encourage you to borrow or rent one for a few days. I found it to be sharp to an extent that wasn't always welcome depending on the subject I was shooting. Nothing that couldn't be fixed with slight tweaks in RAW, but it is almost too sharp in some cases, especially if you stop down the aperture a bit. I found that it was a very nice complementary lens to go with my 23mm f/1.4, which is my workhorse. I'd be hesitant to switch from a 14mm + 23mm combination to the 16mm though.
Is there any sensor specialist out there who can answer my questions/thoughts about global shutter:
- When we will finally get sensors with real global shutter?
- Did this means that we can get rid of the mechanical shutter, or will there still be reasons to keep a mechanical shutter? (My understanding of global shutter means no more mechanical shutter.)
- When will it be possible to synchronise flash with electronic shutter? (Not yet possible with Sony's A9 almost global shutter!)
- This should mean that we will not need HSS anymore, right? How much less power will need our outdoor flashes?
