While the Lumix FT3 and FT4 are more expensive, they are not necessarily better, it's just their use that differs from what Lumix FT20 EF.
The Lumix FT3 and FT4 are made for experienced adventurers. People doing extreme thing very often. They have a GPS (for extreme adventurers, are lost !!; 0) and the FT3 has 3D.
The Lumix FT20 is an auxiliary or secondary device to do the same thing these fighters, but less extreme and less often.
It is a holiday unit at sea or winter sports or for leisure sports such as mountain biking, water slides slips in the water parks, water sports, skiing ... This camera will replace your primary camera, you do not want to damage or take in these places and you do not want your children touch !!
It is a device designed for the whole family and children so it is simple.
pictures: same level as photos taken with an iPhone 4 or HTC Desire HD, so beautiful to some, but not enough for others. Only flat for my taste: when the wide angle is set, the brightness is lost.
Full of different mode: Continuous, animals, underwater, beach, baby, food, soeli sunset, dawn / dusk, mountain, snow, fireworks, portrait miniature ect. Sepia, black and white, standard and vivid colors.
Video: perfect, HD, plus it has a thumbnail mode, which movie while accelerated. The sound is very good. opportunity to take a photo while filming. Anti shake, anti wind.
The battery is rather good, 2hr30 non stop 1hr30 photo mode and video non-stop mode.
Taking a quick, time to wait between a short photo, very receptive apparatus, very fluid. It is lighter and more compact that the FT3 and FT4. The menu is very simple, because the kids love colorful, very easy, very fast. No need to press 20 keys for a function, there are plenty of shortcuts. A cd rom photo editing comes with this unit over a picture transfer logitiel that can also put those pictures on facebook, twitter or in two seconds or videos on you tube.
This device is resistant to impact, is when he falls onto concrete, tile, earth, pebbles, stones, ect .. 1M50 to the ground, and although he is still alive; and even if it falls then you do an action, such as a bike or rollerblades remains alive. Your child can take it and you no longer let him do paniquerez fall !!
I test the seal in fresh water, is good is nickel. Panasonic has incorporated a tutorial in the camera you will see the first time you turn it on or when you select the modesplage or underwater. We must follow this tutorial is everything works !!
We can stay 60 minutes under water and we can not make diving bottle with, I think it must be because of the pressure. You can snorkel, take pictures underwater, take the fish etc, and he risks nothing if your child spills a glass of water on it. (But in terms of a soda or juice I do not know!). I would say this was what was in the sea water.
There ... in conclusion, this is a good camera, secondary or booster that allows you to enjoy your holiday, or doing outdoor sports, taking pretty pictures memories without worrying about damaging this device (as shock resistant and waterproof) or use one that cost you an arm and you do not want or take your children, lest they be overthrown or wet, or your parents, for fear that they comprise anything because too complicated, or your friends to steal the fears that you or laugh at you as too big ... (lol). This Lumix FT20 EF, will be the way for your children to discover the picture for your parents to understand the photo and your friends you push in the pool for one of them to take a photo under water , saying after you: "It is very cool and convenient this unit" !!
