Pentax Optio A20

 

To be honest, when I got the Pentax A20 for review I expected it to be a simple point-and-shoot ultra-compact with probably a few manual exposure features, like most higher-end ultra-compacts out there. But then again, this wasn't the first time my...

In a case like this, its easy to forget that at the end of the day, the Pentax Optio A20 is still an ultra-compact, and with that size come a lot of limitations. Comparing it directly to the likes of the mid-range Canon Powershots would be ridiculous,...

If you're new to digital photography you may wish to read the DigitalPhotography Glossary before diving into this article (it may helpyou understand some of the terms used).

Good resolution, natural accurate color, subtle processing ; Subtle noise reduction holds onto detail higher up the ISO scale ; Excellent all-metal construction ; Good white balance ; Good flash performance ; Very compact ; Shake Reduction ; Useful...

Slow focus ; Fairly high shutter lag ; Slow flash recycling ; Shake Reduction not as reliable as some competitors ; Noise visible even at ISO 64, especially in low light, very noisy at higher ISOs (see above, however) ; Images a little soft - and not...

To quote from my own review of the A10, 'As someone who first got hooked on photography with a 30 year old Pentax and who has had a soft spot for the brand ever since, I just hope the next generation of Optio can build on the A10's undoubted strengths,...

It takes great pictures. It is small. It has a decent Zoom

I wish it had a shade provision for bright lite shots

Owners Opinion: Pentax Optio A20 (*isteve, 13 Jan 07)

 

This camera has a lot of excellent features for the price and its pretty customisable. Overall image quality is good with excellent colour and lots of detail. I didnt find AF to be too slow when set to centre point only, and the face recognition seems...

Noise is visible even at ISO100, though there is very little detail loss. There is also some CA and softness at the edges at wideangle but its better at longer focal lengths. Generally the noise suppression seems to favour detail over NR, but there is...

Owners Opinion: Pentax Optio A20 (Aiolos, 9 Jan 07)

 

Used a lot of time comparing different cameras in ultra-compact class and decided to buy Pentax A20. I must say that I have been statisfied with this camera. I think the sharpness and detail in this camera are excellent. I also like the wide manual...

Many reviews point that this camera has a slow auto-focusing speed, and it did feel like that at first, but when I changed the focusing mode to spot the focusing time quickened dramatically ; Battery life could also be better, but I'm thinking of...

Can't beat it

 

Very happy with this camera. Glad I waited a year to buy. 10 Megapixel for this price is amazing. And Newegg just keeps getting faster and faster with their shipping.
