Some first impressions of the C5050-Zoom with the PT-015 housing
Note: Previously I was using a Sony P5 housed in a MPK-5. I don’t regard myself as an expert on underwater digital photography and someone with more expertise might form quite a different impression.
I took the camera on a trip to Kapalai for 10 days, during which I did about 30 dives. The visibility was not good (generally 5m or less) but there were plenty of interesting subjects. On a couple of days we went to Sipadan but even there the vis was only 10m or so.
Overall, after the first 5 dives or so, I thought quality of the pictures was already much better than I had achieved with the Sony after about 80 dives.
What I most liked
- The white balance settings seem to do a pretty good job (once I got it sorted out!) for non-flash pictures. This was a good thing since my external flash wasn’t working well on this trip. Overall I’m very happy with the colours in the shots.
- Ability to save 8 different camera settings and recall them quickly.
- Shutter lag is shorter than I am used to.
- After a bit of messing around with diffusers, I got good exposure results on macro using the in-built flash and its automatic metering, without needing to use the external flash.
- Autofocus seems pretty good (all I need to do now is to find a way to stay perfectly still in the water ...)
What I didn’t like
- The positioning of the LCD screen. You have to be almost directly behind the camera to see the panel, as the housing puts a rubber sleeve in front of it to shield it from light which might otherwise make it hard to see the screen well. It’s really hard to see what’s on the screen if you need to put the camera in a low position to take a shot. On the other hand, when looking at the screen from behind the camera, it’s then hard to see directly an object close in front of the camera, as the housing body blocks the direct line of sight from the eye. This can make it hard to position the camera properly for the shot and sometimes when very close up I couldn’t tell for sure that the housing was not about to bump into the object. Admittedly my depth perception (judgment of short distances) is not too good anyway compared to most people.
- Using the housing, I can’t reliably tell when the shutter button reaches the lock position, so I ended up taking shots before I wanted to sometimes.
- The white balance doesn’t work too well if I point the camera at a white card to set the balance; the subsequent shots were too red. To get good results without the flash I have to find some near-white sand to set the white balance. I can’t work out why this should be.
- It’s a bit awkward to rotate the knob for most adjustments underwater – you need to press a button or two, while simultaneously twisting a knob. Could be a problem if there’s a significant amount of weight attached to the camera.
- I couldn’t work out how to get the histogram to display constantly in Manual mode (no problem in some other modes)
In spite of these compaints, overall I'm extremely happy with the camera & housing.
If you want to see a couple of examples colour balance without a strobe, you can see some sample photos (low resolution only) at http://uk.photos.yahoo.com/d3m2m; the Kapalai photos were taken with the Olympus and the others were taken with the Sony on previous trips. None of these have been processed in Photoshop, but some have been cropped. This will sound silly, but due to an accident (user error!) I lost all the original files including the information about whether I used the flash and I only have compressed versions of most of the photos. Still, I think some Kapalai photos taken without the strobe were 150401 & 221847.
For the extreme close-up shots I didn't use the super macro mode, instead I was using normal AF mode with a close-up lens. These close-up shots all used the camera's internal flash; I attached a diffuser to the front of the housing to try to avoid having a shadow from the lens cover of the housing.
