Just got my new Casio Exilim EX-Z750

Well my good old Canon S230 that I have used for many years and with which I took thousands of photos that you can see on my website has finally died on the last day of my Puerto Rico trip. Although the camera still was able to take photos, the display stopped working. But the good news is that I was thinking of upgrading anyway and this just sped up the process.

After a long debate between the lastest Canon Digital Elph Model SD500 and the latest Casio Exilim EX-750 I ended up going for Casio. This was a diverge from the Canon Digital Elph line that I've been loyal to from the first model S100, to S200 and to S230.

The deciding factor that made me steer towards the Casio camera is its video performance which has two advantages:

Casio's MPEG4 Movie Codec
Both cameras capture video at 30 frames per second. But Casio uses MPEG4 codec while Canon use Motion JPEG. What that means is that Casio's movie files are roughly a third in size of Canon's so I can fit 3 times as much of the video footage on the Casio.
Casio's Movie Audio Quality
What is surprising to me that Canon is capable of taking Video with quality almost as good as DVD, but the sound still sucks big time. It uses PCM compression at only 8 bit and 11 Khz which makes the bit rate 88 kbps. Casio uses MP3 compression at 4 Bits at 44 Khz which makes 176 kbps bit rate. With MP3 compression you can store much more audio data with that bit rate than with PCM, so the sound is almost CD quality.

I purchased my Casio at TechToysForLess.com for $367 which was the cheapest deal I could find. I was actually skeptical about buying the camera from them, but decided to bite the bullet. When I got the camera, I was relieved because it looked brand new as advertized.

So far I love it! The video quality is amazing, so be prepared or the higher quality videos on my website. I love the huge 2.5" screen too. It's very close to the size of my Treo 650. Let the snapping begin!

Here are the detailed reviews of the camera:

Casio Z750 User Manual

Update - July, 2005

I had to ship my camera to repair because of the focus problem that started to happen. I guess it happend because of multiple lens errors that I've had. The camere repair took more than 10 days. The replaced the lens assembly and the problem went away.

Update - August 25, 2005

Casio released AVI component for the Mac so that the video clips from the camera can be played back. Click here to download.

TreoCentral S650 Skin Case for Treo 650 Review

Finally my search for a perfect case for my Treo 650 is over. Today I received my TreoCentral S650 Skin Case. Prior to this I tried two other cases but I think this one satisfies my personal requirements the most. The requirements are:
  • No flip covers. I want to see the screen without flipping anything.
  • Be as slim as possible.
  • No belt clip (to help its slimness). I carry my phone in my pocket, not on a belt. (Don't want people to find out I'm a geek...)
  • Have exposed keyboard for easier typing.
  • Have exposed screen for easier access to screen edges.
  • Have covered corners which are the most vulnerable parts of the phone when it's dropped.
I am happy to say that this case covers all of these requirements. When I saw the case at first I was wondering how to put the phone in there because I did not see how it could open.

Well the truth of the matter is that the case is made of flexible rubber.

To insert the phone into the skin, slide it through the screen opening.

Then stretch the rubber at the top of the phone and pull it over the antenna.

Here is what the phone looks like inside the case. As you can see, the speaker is exposed and there is a little hole for the status indicator. The keyboard is exposed as well.

As you can see the Palm buttons and the 5-way navigator are behind the case. You may think that pressing them is cumbersome. Well actually the rubber is so flexible that it's not a problem at all. In fact the rubber itself has bumps in shape of the buttons so you can feel them with your thumb and press them very easily. It's like having them outside the case.

On the back there is an opening for the speaker, camera and the mirror. On the bottom is a perfectly aligned cutout for the USB/Powercord connector and headphones. There is also a hole at the microphone although it's not visible on this photo.

On top of the phone is the opening for the speaker switch, infra red light, and the SD card.

The side buttons are not exposed, but pressing them is easy because of the rubber flexibility. Having the buttons inside is the only way because if they were outside, they would be difficult to press because of the rubber thinkness and they would not stick out as much.

Speaking of the rubber thickness, I think it's better at protecting the phone during drops than the leather cases because the rubber has greater shock absorbtion.

So bye bye my old cases. My first case was by PalmOne. I got it when at the same time when I bought my phone. The problem with this case is that it just looks plain ugly with that white thread. Also the belt clip mount was not removable and it made the case thick. Finally, the corners of the phone are exposed and are subject to scratches if it is dropped.

Then I tried Krusell Classic Case. I liked the overall look of it better than that of PalmOne. I did couple of modifications to the case. I removed the belt clip mount and cut the opening on top of the phone so that I can remove the SD card without taking the phone out of the case. I liked the fact that the corners of the phone were protected. However, the cut out at the bottom was misaligned with the connectors. I had to stretch the case to insert the jacks.

Both of these cases had the keyboard and screen behind the plastic. Although it does provide additional protection, it is not as easy to type on the keyboard coverd with plastic and use the stylus on the screen especially next to the edges.

So my third case is the charm. I like the way it looks too. It really does not even look like a case. Also it feels very good in my hand. There is plenty of friction and less chance of the phone slipping out of the hand.

The first 3-megapixel Camera Phone


Traditionally the phone cameras have been mediocre, but this one may start a new trend of high-quality phone cameras. In fact it looks like a camera with the additional phone functionality. Click on the picture for more information.

Pocket Video Players

I've been watching Seinfeld episodes on the subway on the way to work on my Sony NX80V for more than a year now. But new stand-alone portable video players have started to come out:

Sony Takes Lead in Small Sizes

Sony has announced the worlds smallest 5-megapixel digital camera and a the worlds smallest digital camcorder. The cool thing about the digital camera is that has this new MPEG mode which can take movies at 640x480 resolution at up to 30 frames a second with length limited by the amount of space on the memory stick. I bet those files are not going to be small. I am also wondering if it is using MPEG4 compression. Hopefully the bridge between still and video cameras will be smaller and smaller going forward. The camera will not be available in the US until January 2004
