Question: which camera is better? the casio exilim ex-ex-ZR100 or ZR400? Which has better features?
Document: Loved the features in this camera simple to use lots of selection and fast too, great color sharp pictures could not ask for better.
Casio is not very popular any more as a camera but I like their design, layout, speed for on and off (which I take hundreds of photos a week so I need quick on and off). As time goes by I will probably have to convert to another manufacturer but as long as Casio keeps making a good camera I will be buying them.
Have had Exilim cameras before and that's why I keep going back. This is a &#34;new&#34; camera for my girlfriend and she loves it. Happy for the purchase!! !
I purchased this camera primarily to have a relatively inexpensive high-speed camera in a point-and-shoot sized package.
I just don't want to take the time to learn the nuances of other camera designs. Been using Casios for about 12 years now. Tried others but keep coming back to Casios.
This is a great camera for photographing sports action or wildlife when you don't want to tote an SLR and camera bag around.Great for the outdoors enthusiast / camera enthusiast who prefers to be IN the action rather than sidelined by the camera.
This camera offers high speed at a reasonable price. It is a rugged design with an easy to understand menu. I would recommend this camera to those wanting to record high speed events. It is faster that iphones or other phone-based cameras.
Camera works great EXCEPT there is no shutter speed on the video so, it has 240 fps, but without the shutter speed, filmimg golf swings is not clear. Sad they left that out on the video. The camera has the shutter speed on the camera picture taking but not on the video capture.
This is a small light little camera with lots of muscle. I does all of its basic jobs well. HDR ( high dynamic range) works well and is a great addition. Panorama shots are the best I have encountered. What does it lack (Raw file support ) the manufacturers description  of what the camera does is a little off.
I don't know why it is so expensive on Amazon but I bought it 16,000 Yen at Japanese online store. About $200.USPS doesn't take lithium battery from other country so we have to buy battery in here though.I don't know much about mechanical things and I'm proud of it but this camera works pretty good for me. I take pictures flowers, bugs, dogs, cats,,, something like that.Battery life is very long.Micro is very clear.Very bright.
Answer: The ZR100 his a camera I use and it does everything that I ask it to do. I have never used the other one, so I can't comment on it. The quality of pictures I get is very much what I expect, that's why I looked into it before I purchased it. I am on my second one.
