Olympus E-450 review
The omission of video capture and a high-resolution LCD are understandable given the model’s price point, but it’s worth noting that the model is almost the only recent release not to have image stabilisation included in either body or lens. Presumably, this is in order to keep the body small and light, as well as cheap, and to draw a further distinction between the more expensive E-620 model.
In isolation it’s a capable model, and with the exception of image stabilisation there isn’t really anything ‘missing’ that we may expect on a comparable camera. If it’s a model you’re considering, though, I’d suggest you look first towards the E-420 to see whether it will provide what you need for a little less outlay.
