Pentax Optio E40


Pentax's Optio series is just one of the many digicams aiming to make a stab at perceived consumer requirements. Having had a chance to put the Optio E40 though its paces, here are my findings.

Video Video capture is in .AVI format and this may be the one of the better features of the camera. I even managed to record some fireworks at night from a distance with the zoom and I have to say it looked quite good on PC playback. Battery Frequent...

Pentax Optio E40 Review


The Pentax Optio E40 is the latest entry-level point and shoot from Pentax.

Nice compact size and good ergonomics ; Easy to use ; Good battery life

Lack of detail in shots ; Slow autofocus (at times) ; Noisy images ; Weak flash

My second one...


Bought my first one last spring. Takes awesome pictures! My neighbor girl borrowed it for band camp and liked it, so I gave it to her...bought myself another one for Christmas.

Good camera for the money...not the best, but also not the worst

Like any AA powered unit, it EATS batteries

Consumer review by:



my brother in law bought an expensive Canon digital camera. it disappeared in the hotel. buy a "disposable" and you won't be too upset if it gets lost, dropped, spilled-on, or the dog chews it up.

Price is very good. Uses AA batteries. I use the Sanyo Eneloop batteries, with a slow charger, and get great results. Also uses the standard SD memory cards. So, no proprietary stuff here -- i just pop the memory card into my computer, and go. i like...

Not the best, but nice


I haven't had this camera too long so I can't give a full detailed review. It does take some wonderful pics, you've already looked at the features it comes with. At the price it's selling for it's probably one of the best buys you can find. It does not...

This is a decent 8.1 MP camera with a great price. The features are very nice and it takes relatively clear photos. The LCD screen appears much nicer in person than I'd have thought. Very clear. It has a nice feel when taking pics unlike some cameras...

It's very light. That is good and bad. It's made out of some kind of plastic and it feels very fragile. I'd have prefered a more solid body construction, but can't complain for the feature set and the price. It uses 2 AA batteries. Some people like...
