I have Canon S3 IS and I am happy with it, but I wanted second small camera for some occasions when I don't want to carry big camera. I bought Casio EX-Z300, mainly because it has wide lens and HD video, but I will probably return it.
At the beginning I liked it. It's very small, 28mm lens is great, intuitive menu, manual ISO and WB, big LCD with good viewing angels and some good scene modes. However there are some things I don't like:
- Picture quality. When I looked at sample pictures at Steve's DigiCams review there were good - sharp without noise. However they were taken in sunny days. My pictures taken now in dark rainy day are not so good. If I compare it with my old Canon S3 they are worse even S3 has only 6MPx and Casio has 10MPx. Canon produce sharper and cleaner images.
- HD video. I was wondering how video will look like, because sample video from Steve's review was not good while video from http://dc.casio.jp/product/exilim/ex_z300/ ... gallery.html was pretty good. My experience is that if you put camera on a tripod or don't move camera a lot you can get good result. However when you move camera quickly quality is rapidly getting worse. Video is in MPEG4 with bitrate about 7Mbps and I think it's not enough. MJPEG video from my S3 has 15Mbps and I usually convert it to MPEG4 with bitrate 5Mbps - if I would use lower bitrate quality degradation would be noticeable. Video resolution of Z300 is 3 times bigger so bitrate should be at least 15Mbps and not 7MBps.
- Dead pixel(s). I found out there is a green spot in every photo. Probably only one dead (or actually stuck) pixel, but because I can only get jpegs it affects many pixels around. Approximately area of 6x6 pixels is affected. Strange is that this stuck pixel moves between two different locations: once it's at position 1554,2215 next time it's 1549,2229.
