I've looked recently at some of the newer fixed lens SLR's. The ones with about 12 MP and 24x optical zoom. Most seem to run anywhere from about $350. to $500. I'm curious to hear opinions or experiences, likes and dislikes. I'm currently still using an Olympus E-10, so any of these seem a big jump up, yet much cheaper than buying a body with interchangeable lenses.
Thanks
Technically speaking you're referring to a ZLR (Zoom Lens Reflex), there are benefits to that sort of thing, but at a cost. You're stuck with the lens that comes with it for better or for worse and have to put up with a limited range of zoom. On the upside though, you're not going to have any issues with dust getting into the sensor.
Yes, there can be a significant premium over the ZLRs to get an SLR, but I'd recommend that you consider what it is that you're planning to do with the camera. For many people, the ZLRs are just fine, I mean they wouldn't sell if that weren't the case. But what you're getting by plunking down for the dSLR is primarily flexibility and quality. A long zoom is always going to result in a drop in image quality, depending upon the manufacturer and lens it can be substantial.
It's also worth noting, that you can get a decent Rebel complete with basic lens for not that much more, and the results are probably going to blow pretty much any of the ZLRs out of the water. I'm a Canon guy, but I'm sure that Nikon has similar offerings at this point, and really you're probably better off looking at their offerings than a lot of the competitors.
