Default Casio EX-Z40 vs Pentax Optio S4i

Looking for a small 4 MP digital camera and I narrowed it down to these two.
Opinions on which one would be reccommended?


Would I be more happy with one over the other? Use would vary, bascially I would use it to take pictures everywhere from people to cars to sports to sunsets to my dog...

Thanks!!

Also, I know the Casio can take videos of unlimited length, do you know how long of a video the Pentax can take?

I received my S4i about a week ago. I bought it for the small size. It's a lot smaller than the Casio. It's even smaller than the Sony T1. It's certainly not the best camera you can buy, but it's pretty good and again, it's very small. That was the overriding factor for me.

If I were to own only a single camera, the S4i would not be it. We also have an Optio 555 which is somewhat bigger and in my opinion a lot more capable. Not that much difference in price.

As far as I know, the video limit is determined by the storage card capacity.

Thanks for the reply.
I have a Cannon powershot which is great but very big. I need a really small camera which decent size pictures so the S4i might be the ticket.
Is the picture quality more than enough for web and e-mail pictures?

I assume the lens sharpness, etc. on this camera is very good if not excellent, because most Pentax digital cameras have been rated that way. I have not really put it to the test yet, because I just got it, but I have taken a few pictures and unscientifically determined that it takes good stuff. We will be in Maui next week, and I expect I will have a chance to test it more.

The S4i is a 4 MP camera. I have enlarged pictures taken with other 4 MP cameras that I have owned to 12" x 18", and we have several decorating our home. They really come out great.

I don't think you will be disappointed with the quality of any enlargements you decide to make.

One thing about these really small cameras which you should anticipate is that the flash is rather limited. It's OK for closeups, but it won't fill up a room with light. The 5MP Optio 555 for example has a flash that is usable for twice the distance of the S4i.

You may want to download the Pentax owner's manuals to get you further along in your decision:

Default Pentax S4i vs. casio Z40 I tried them both

Pentax Advantages
Smaller
Easier to use menus
Remote for Family portraits Capable ($30 optionn)
Video Out for framing self portraits or picture review
Do not have to use a cradle for picture transfer (just a usb cable)
My Preference.


Casio
1230mha batteyy vs. 710mha
About 220 pictures vs. 125 Pictures.
Cradle for Picure transfer for those who prefer it.
------------------------------------------------
Not sure wether this new NP40 battery also works in the Pentax.
Spare NP-40/LI8 batteries of the 710mha variety can be h ad for as little as $15.

Not sure I will bother buying one. My old Nikon had 650mha battery it was always enough for me.

As far as I know, the only differences I could find were that the Casio doesn't have a video out to tv feature, but Steve's write-up would indicate that it takes better pictures than the S4i.

The casio has no remote option if thatis important.

I considered both, their both good cameras.

There may very well be sample problems, so as always buy on credit card and with a place that offers a money back guarantee.

P.S. Although I love my s4i

If a little bit bigger camera is no bother e.g. the Casio.

One also has to consider the Canon Elph, Sony new W1/p100 etc.

Hi there,

You want to see some of my first pictures taken with the Optio S4i, which is also my first digicam. I added the Exif-Data for full details. In the overall I am happy with result but am still trying to optimise and use more of the features like filter modes, histogram a.s.o.
