Sony A6300 Lens Recommendation

Used a NEX-6 for some years, so I assume lens selection will be similar. The 16-70 "Zeiss" is pretty good, IQ-wise, but the MFD is a p.i.t.a. and using close up filters will give you ghost rings. And you need to use a dome port. I didn't try the 16-35 F4, as the focal length for APS-C is not that interesting, the lens is pretty big, and nobody knows what combo of diopters and dome port will work. How you'd want to run a macro converter on that - don't know, but then, it's early in the morning. The kit 16-50 is actually not bad, especially around 40-45mm, and you can run all kinds of stuff on top of the port, with the CMC it's very good, and the new wide angle wet lens could also work. The 10-18 is good, the 12mm Zeiss is actually very good (but no fun to install), and I've looked into using the Canon 8-15 with the Zen 170 dome, but didn't do that, went to a DSLR instead - should work, though, if you can improvise the zoom gear. The 90mm G Macro is excellent, but AF so slow, you'll run out of air, actually about the same speed as the Canon 100mm L / Metabones combo. So what I'd do is keep the 16-50, get the 10-18, and the 90mm, and be happy with it. If you want to shoot everything on the same dive, get a RX100, those days are over with this camera. Enjoy the dive and take pictures of the things you brought the lens for.
