Olympus SP-310 Review
The SP-310 has a fairly conventional, conservative design (with a smidgeon of - dare I say it - Canon PowerShot about it). It's an all-plastic body, which keeps the weight (and presumably price) down, but feels very rugged and able to take the knocks compared to some of the shinier metal-skinned models on the market. It's also light (180g without batteries) and very compact compared to most budget models (the nearest direct competitor, the Canon A620 is a little bigger, and quite a lot heavier). There's a fair amount of external control gear, which makes manual shooting a lot less painful than with many models.
In your hand
The SP-310 feels remarkably good in the hand, the weight is very evenly distributed, so it's well-balanced, and - as long as you don't mind the warm feeling of an all-plastic body in the hand - it seems very well put together and certainly doesn't scream 'budget model!'. The handgrip is large enough to make the SP-310 feel very stable - this is one of the only cameras I've used in recent months that feels stable when held in one hand.
