So after a few months since I got the Nauticam housing I finally had the time to get in the water and try it on.
I was in Barbados for a week and although the diving was not exactly outstanding I did have enough to test the camera behavior.
The link to the videos are here for YouTube at 1080p
or if you prefer Vimeo at 720p
The footage was all taken at 1080p50 the highest mode of the RX100. The RX1oo can work in both PAL and NTSC standard but I chose the PAL mode just to avoid the annoying NTSC message at startup. The clip has been edited with iMovie 9.0.9 and then exported in 1080p25 using Xencoder codec for quicktime in high profile. Youtube then reconverts it to its own specifications, but at least I have the highest possible starting point.
As mentioned the RX100 shoots at shutter speed of 1/100 in 50p mode and this suited me fine in case I wanted to produce a 60p clip for viewing on the computer as currently no online system supports it.
As discussed in the previous post I shot all wide angle in camera Program mode. This allowed me to use the left control wheel button to call the white balance set menu that in video is not available. I set the picture format to 16:9 so that would show similar on the screen. I did notice that when I actually started the movie recording the crop of the active steadyshot kicked in with a reduction of field of view of around 9 degrees or a 1.14 zoom equivalent.
However the active steady shot was well worth it as I have not used any stabilization for any part of this clip and therefore not introduced any extra cropping.
The wide angle shots with the RX100 are an absolute breeze when you use a filter and there is no need for custom white balance until it gets too deep to actually use a filter. I struggled getting decent results with custom white balance, the 9900 K error came pretty much every time except when in shallow water and balancing on sand. Also the results were off with too much magenta tint to the point I had always to correct it.
Ultimately I kept the filter and the camera in Auto White balance and did not bother doing a custom reading at all. The results were excellent.
In deeper water the filter started making the image a bit dark so I took it off and used a temperature setting of 9900K with Magenta and Amber at the maximum.
For close up at distances over 20cm I still shot in program and had good results. When getting super close or macro I used Movie mode in Aperture priority mode with aperture set at f/11. Towards the end of the clip you can see a shot of a small pink frogfish that is done like that. The close up on the eye is shot with two stacked Inon UCL165 the depth of field is really small as you can see but still workable considering I hand held the camera at all time.
When I shot this arrow crab I had left the camera in program mode so it chose an aperture of f/5.6 you can see that whilst the mouth is in focus the arrow is not
Similar situation with the pedersen shrimp where not everything is sharp in focus
Obviously I am being very exigent with my footage and in normal condition this is already good to very good.
So what I liked and what I did not like about the RX100 Mark II:
- The ergonomics and ease of use are outstanding
- The camera performs incredibly well with a filter in auto white balance
- The manual focus with peaking works extremely well
- Dynamic range and colors are outstanding and not just for a compact
- Image crisp even in the corners at f/1.8 compared to the Mark I this is extremely significant
- The active stabilizer was great and meant to manipulation in post
- Battery life is incredible
- Performance in low light is excellent and better than the Mark I the camera never reached the ISO MAX of 800 I had set hitting a top of 640 at 30 meters
- Autofocus at wide end in bright conditions is superb
The only think I hated was the custom white balance results an absolute disgrace, to the point that there is no benefit doing it. Not only that the few parts of the clip I had used it and correct it were still a bit off and required correction in post to a small extent.
Also to consider some of the topside capabilities of the RX100 Mark II just to give an idea though this is not exactly the same location have a look as this shot with a Nikon D7100 with sigma 17-70 in comparison with the RX100 Mark II
There is a difference but considering the size of the RX100 and the fact it fits in a pocket I don’t think there can be that many complains. Obviously once you look at specific lenses for the DSLR things change but in the 28-100mm all purpose range I would say that the gap is not as much as double as the price of the two set ups.
So is the Sony RX100 the best compact underwater video set up? Definitely
Is the Mark II better than the original RX100? Yes and well worth an upgrade for video
How does it compare with the Panasonic LX7? The dynamic range and the colors are superior and produces footage that is simply better and sharper. Where the LX7 excels is at macro in clear waters, this is not because of magnification as the RX100 and LX7 perform exactly the same with diopters, and this is because of the LX7 amazing autofocus. However with a bit of silt or other objects in range there is need to switch to manual focus and there the RX100 is actually superior when using peaking even if the depth of field is actually less, the manual focus on the LX7 with the magnifier is not as good unfortunately.
So my ranking for video is:
1. Sony RX100 Mark II
2. Panasonic LX7
3. Sony RX100
I would also add that for stills the LX7 is even more rewarding at macro range due to the performance of autofocus.
