-no dials for aperture and exposure like the LX100
Where do you read that? The LX100 has the aperture and exposure dial, just look at the picture of the LX100.
For the cons of Sony, custom white balance is a nightmare.
Just head over to the video section of the forum and you will find more info and sample.
If you absolutely want to do macro and wide angle in one dive, another option is Panasonic GX8 with the 14-42mm lens. You can put the Nauticam CMC and the WWL-1 wet lens on this combo. However, you will have to increase your budget a bit, and the 14-42mm lens is slow. I use the LX100 because the F1.7 come in handy.
Likewise someone who is fiddling with their camera and does not know their rig is just an unwise photographer that should have tested new equipment in the pool and now is messing around in water.
So base on your logic, if one mastered the camera in the pool, he/she shouldn't fiddling with it in a real dive....... you do know the pool is a controlled environment while the real dive is different in light/visibility condition right?
Also, I would be cautious to leave the rig in the rinse tank for more than 10 minutes. There is a risk of people just dump their rig on top of yours, causing things to open/become loose. Yes, I read that it happened to people.
There is no harm to take an empty housing out for diving for the first dive once you arrive at the destination, that's why most resorts require a "Check out dive". The check out dive is critical not only it lets you test your housing integrity, but also allows you to:
- confirm your BCD, regulator etc is working correctly
- have the right amount of weight (especially if you gained weight since you last dive)
- get use to (observe) the way the dive master work
- learn how your dive buddy behave (especially if you have a new dive buddy)
- observe how the boat crew handle your camera setup on and off the boat
I have seen many divers bring camera during check out dive, and it makes the divemaster's job difficult because they want to see how you dive and behave underwater. Often time they couldn't get the diver's attention because the diver just fiddler with camera and swim away from the group so the divemaster assume that the diver is "obnoxious" or "Mr/Ms Know it all" (This is especially true when you deal with Asian divemasters). I paid attention during check out dive and I can sense the diver master feel being respected, and guess what? For the remanding of the dive trip, he found critter/creature and let me know right away, and it's a nice divemaster/diver relationship. I seen some divemasters found critter, and don't bother to show it to the "Mr/Ms know it all" because they are far, and tend to ignore the divemaster (or the divemaster perceive that those divers don't need the divemaster's service). My point is, first impression do makes a difference.
I think the mentality of "wasting a dive" is not that true consider most check out dive are done in house reef, or some dive site that's shallow/less interesting. It's better to be safe/cautious than sorry.
I think you need to consider Mega OIS vs Power OIS on the 14-42 lens first. I don't know how useable is Mega OIS when shooting video. I tried the 14-42pz when I rented the GH4 housing to test out, it's barely stable.
