Yes, its a Nikon vs Sony, vs Cannon vs Ect. Topic. But read everything here. I've been trying to do my research here on bodies, personally from everything i've read (and my own experiences, albeit limited, don't tell me anything different) pro/FF bodies are, more or less, personal preference. Which feels better to you, which do you like, so on and so forth. Which doesn't bother me. It would seem through out the digital era they all go back and forth anyway. I've looked on the forums but mostly all these types of posts focus on the body and i'm interested in lenses. On a foreward about Sony, as the a200 is what I have, I really do like the body, light, and more then capable for what I do. Which brings me to my next point. I don't intend to upgrade soon. I don't think i've outgrown what I have but that raises questions in my mind which I havn't been able to bed down on my own research. To my mind, for cost and proformance Lenses seem to be conciderably more important than whats in the body at the upper teir models. I mean, isn't Sony making Nikon sensors right now? I like the Sony system, and would almost stick with them save the fact they are new and photography isn't there bread and butter and i'm concerned they would pull the plug if they don't meet sales quotas. But it does seem like they've came a long way in their lenses. Lenses can make or break even the best camera body, and after you get a good set, probably cost significantly more then your body. So as for a system goes, where would the picks be? Not that bodies arn't that irrelivent, but there are advantages and disadvantages to any company at the pro/FF end but seem rather less important then whos lenses do your trust. Not something I'm intending to do tommorow, but i'd rather have an idea of where to start then buy into a system an realize that i've spent 5 grand on stuff that isn't going to meet my needs. If its relivent, I don't have a particular area of focus yet, nature photography, weddings, action shots, whatever. I photograph everything right now, just trying to find my way as it were. Its not about money either, they all seem rather comporable in pricing, save nikon's new D3X. Maybe i'm reaching here, or overthinking it.
