I'm hoping you can help me. I've been reading online for days and days and still don't seem to be making any progress with making a decision for a new setup.
A bit of background: I have been using a Canon S95 on full manual in a FIX housing plus 2 strobes (YS-01s), uwl-04 wide angle and epoque dml-2 macro lens. I do around 150 dives a year, all in blue, clear water. I mainly take stills, but I do like to take a bit of video now and then and video quality is important to me. I have a separate GoPro Hero4 with lights and it would be great if I could find a stills camera which means I can do away with the GoPro.
I tried out a friend's Canon G9X Mk ii with Fantasea housing in March, and I enjoyed using it - it felt quite familiar compared to my S95. But I'll be honest, it didn't really excite me - I would consider it an updated replacement of my S95 rather than an upgrade. It's still a perfectly sensible option but I'm wondering whether it's worth putting some extra money in to have something better...
I could go into the nitty gritty of all the pros and cons I've found (of which there is a lot, hence I haven't been able to make a decision), but how about I just throw out my current choices and see what you all would choose: G7x ii, G9x ii, Sony RX100 iv, Sony RX100 v, or go off-piste with Olympus EM5 ii.
Also, a separate question - how do you know if a lens would vignette? For example, if I chose a housing with 55m thread (e.g. sony rx100 iv in fantasea iv housing) and used it with a fix uwl-04 (52mm thread) and step ring, would that vignette?
Thanks all for your input,
