Lumix TS4 Waterproof Camera Review

Review

I recently purchased this waterproof camera to take along on my kayak trip to the Everglades. It cost just under $300 online. The results so far are impressive, especially the high-res video.

After a month I’ve become pretty familiar with its basic functions, but the PDF-only manual is thick and there are lots of bells and whistles I haven’t tried (such as time-lapse). Here is my quick review…

“Waterproof”

It seemed to survive the salt water nicely, though I did not open the battery/card door during the trip and did not use it underwater. I bought a floating wrist strap that worked well. Very nice not to worry about getting it wet! There are two caveats however: 1) It is very easy to get water or salt residue on the lens window. Inspect and clean it often. 2) There are controversies on the web regarding water damage, warranty service, and required replacement of the door seal. My impression is the company is beginning to listen to customers who had problems and is making maintenance easier.

Basic Photography

The basic functions are all there and reasonably well implemented. The location of the wide/tele buttons took some getting used to (they are on the back where you can hit them with your thumb). The Manual Mode is a bit odd in that you only have two choices for aperture (f3.3 and f10 at full wide). I thought it was broken at first. (Perhaps there are only two apertures available in full auto as well? This might be a reasonable design compromise for a small camera.) Switching to shutter speed takes another button press. This is clearly a design flaw since most of the adjustment comes from the shutter. In Manual Mode it should default to shutter speed and aperture adjustment should require the extra step!

Video

The video sequences I shot in the Everglades were truly impressive. I set the camera to capture high-res mp4. The raw files fill my desktop screen and I’ve had to reduce the resolution to use them on the web and DVD. I’ve edited the best clips together into a short movie so you can judge for yourself!

Panorama Mode

Based on one example, this seemed to work well…

This is where the extra steps and awkwardness of Manual Mode became painfully apparent. The process was complicated by the fact that the “meter” hides itself between exposures, so I had to partially depress the shutter release each time I wanted to make adjustments. (Perhaps there is a setting somewhere that will override this? I should probably just revert to doing the exposure math in my head like we did back in the old days before meters became common. <smile>) That said I was able to get a few decent two-exposure HDR photos without too much frustration…

To get these quick-and-dirty high dynamic range (HDR) photos take two photos of the same scene with the same aperture at 1.5 and -1.5 EV. Then combine them in Photoshop or your favorite HDR software.

Conclusion

The gallery below shows a general sampling of the photos I’ve taken in the past few days. Overall I am quite pleased with this camera and its minor faults are more than compensated by being waterproof!

Kayak Sailing on Little Lake Santa Fe

Nice day for sailing! Wind was about 12 mph with some gusts, warm but not hot. I recently bought a 2010 used Hobie Adventure with the optional sail. It works amazingly well, especially considering how narrow the hull is! (The first day I took it out in heavier winds I turtled it. It was very easy to right and self-rescue!) To be very specific, the rig pictured here does not depend on the pedal drive (an amazing bit of engineering that!). It uses a two foot dagger board that inserts through a special slot in the hull. I also have the larger rudder installed. Below is my informal review…

The asymmetrical controls take some getting used to. The “tiller” is a small lever near my left hand. It works in reverse, you turn it the direction you want to go rather than away as in a traditional sailboat. The dealer had added a small pulley to the aft lift point for the sheet. I discovered that there was a small eye fitting near the dagger board that served well as an informal block. This allowed me to pull the sheet upward and sort of lock it over my leg. This position was comfortable, easy to maintain for an entire tack and could be quickly released if there was a gust. I found it more natural to sail on a port tack because of the controls. With the boat heeling to the right I could lean to the left and still have full control of both the tiller and the sheet. (I can actually reach my left arm out and around the hull to hold on!) On a starboard tack I was leaning away from the tiller and into the sheet. This was a bit awkward and limited my ability to hike out. Not a big deal, just a factor you don’t have in a standard sailboat.

This is serious sailing craft in winds from about 8 to 16 mph. In light air you’re better off paddling or pedaling. When the wind is gusty above 20 mph it becomes difficult to keep the sail trim for more than a few seconds. You’re forced to let the sail luff to avoid capsizing. On the other hand, the challenge can be part of the appeal! <smile> On a warm day with warm water this is a very safe boat to tip over. (There is also an option to partially reef the sail by rolling it on the mast. I have since tried this and it works well!)

The boat turned well both coming about and jibing. I was never “in irons” and since there is no boom there is nothing to swing across and hit you in the head. I used the paddle only to get off the shore. It points well and tacks upwind effectively. It seems to go fastest at a beam reach. When going downwind I discovered I could improve performance by holding the sheet out to the side with a free arm. The telltales are very useful, which surprised me for such as small sail.
