Olympus TG-4 vs Sony A6000

adding light helps a lot under water ;-))
Even for your TG4.... Maybe a set of used middle class strobes?
The Sony is a much better camera, with the same amount of light, the results will be much more impressive.
So first step would be strobes, and then a housing for the Sony...
But that means a lot of money, first the housing, then ports and maybe other lenses....
So what is your primary interest? Macro or wide angle?
Will wet lenses be fine, or just the best prime lenses?

I didn't have a primary interest yet.

Also bear in mind just because you own a camera does not mean it's the best option to put in a housing and take underwater. In order of improving quality you would have the compact like a TG-5, then a 1" sensor like an RX100, then micro43 like Olympus, then the APS-C Sony. As you increase sensor size you go from the 1" compact with inbuilt zoom and no ports, to mirrorless m43 where a typical dome port is the 170mm Zen, to APS-C where you are looking at a 200-230mm port for a rectilinear wide angle. As you go up in sensor size, costs go up. Also consider the lenses available. There are two fisheyes in the m43 lineup while the Sony doesn't have a native fisheye lens, only an adapter and the WA lens range is more limited. As you go up the olympus and 1" semsor cameras and also possibly the m43 could use the smaller cheaper S&S YS-01 or INON S-2000, while the Sony would benefit from the full size Z-330 which is near twice the price. The Sony has Auto flash only while the olympus will do manual flash. The battery life also varies among models.
I would suggest tabulating your options like this: the table shows the prices to setup for macro with an A-series Sony, m43 and two 1" sensor cameras, assumes Nauticam housing and port from Aus distributor and camera/lens prices from Digi direct.
You could buy your strobes now to use with the TG camera and work out which direction you would like to go. Then price up the whole system, lenses, ports etc to see what you are up against

I should also add looking at your shots, a lot of them could be improved by getting closer and employing different settings. for example your cuttlefish shot, is well lit but quite noisy. The settings used were :

Thanks Chris. That's super useful information, especially the keeping the ISO low and getting closer to the subject.
I'll look at getting a strobe or 2 for the current setup as well as a wide angle wet lens.
The barracuda was shot in RAW and then post-processing with the white balance. It probably got made too blue in the edit.
Might bring a white card down next time so that it's easier to set the white balance in the water then try to do in lightroom
I guess I'm on the search for strobes and a wet lens

Your pictures are great! I would recommend thinking about composition and how to make the subject more interesting, but overall great pics, well done!

In order of importance, if you're looking to improve your photos, I would recommend the following steps:
1. Get close. Even closer. Unless shooting macro subjects, shoot a the wide end of your lens (don't zoom in -- get physically closer) at the lowest ISO possible. Get a wide angle adapter to allow you to get even closer to your subject while still keeping it in the frame. This is going to do a lot more to improve the quality of your images then getting a new camera would.
2. Get a strobe. Initially it's quite fine to start with just one and master that before getting a second one later.
With proper technique and lighting, you can get amazing results from the TG-4.. basically as good as you can expect from any larger camera. A different camera won't enable you to take better photos, but a wide angle adapter and lighting will.

Thanks Wayn, yes I'd say the linked photo would look like crap without strobes it's about 15-20m down on a wall and there would be no red light without them. The visibility was in the 30-40m range so that helps a lot as well as well. On top of that good post processing to boost contrast is alsopart of it
That shot was taken with a fisheye lens so I was 500-700mm away from the subject which also help a lot.

A bit of an update to this post.
I accidentally removed the original album that I posted so here it is again:
Photos with lights can be found in this album:
After much research I ended up settling on:
- SeaLife Dragon Video Lights, 2 @ 2500 Lumens - https://underwater.c...n-duo-5000.html
- SeaLife Wet Lens for the housing - https://underwater.c...-dome-lens.html
This setup meant that I could shoot macro and wide as well as photos and video. All on the same dive. Not sure if that's necessary but worked for me.
- The light really makes a difference to the colour
- When I was diving I thought that I was missing the extra brightness of strobes but after reviewing the images and video I'm happy. Having the continuous lights meant that the videos also had colour in them (if I wasn't too far away)
- The wide angle lens was OK. I have a love hate relationship with this lens
- Pros: Takes good photos when you can frame the scene. Closer mean colour was much improved.
- Cons: 52mm ring attachment is a pain to get on and off, burping with a ring tedious, really need to be very close, had issues on where to store while shooting marco
- I also worked a lot of settings, keeping ISO < 200, exposure comp, not zooming too much. Backscatter.com has a really good printout to take on the trip: https://www.backscat...Camera-Settings
All in all I found the setup pretty cost effective and flexible. If I could work out a good way to mange the wide angle lens that would be ideal. There is a quick adapter for the sealife camera and lens holder. This would be really good. Something to work on for the next trip.
Lastly, I started having issues with the housing. It started fogging up. I checked the o-ring multiple times but always ended up fogging around the 50 min mark of the dive. Have ordered a new o-ring so hopefully that solves the issue.
For anyone interested, a write up of the trip can be found here:
