In other, similar threads, I've told how I decided what photo gear to buy. I asked myself, 1) Where do I want to go? 2) What lenses will get me there? 3) What affordable body supports those lenses, and will I be happy with it for awhile?
Question 1) meant: what do I want to do, that I can't do with my 5mpx Sony DSC-V1? The answer: interchangable lenses, ultrawide, long tele, and low light. Everybody makes (more-or-less affordable) long and fast lenses, so I concentrated on ultrawides.
Question 2) meant: which ultrawide zoom(s) could I use and afford? In spring 2008, when I did this analysis, Sony had none; Canon and Nikon (and thus Fujica and Sigma) were too expensive; that left Olympus and Pentax.
Question 3) meant: who makes a good solid affordable body, with better than entry-level resolution, that I won't feel compelled to upgrade within a couple years? Again, non-crap Nikon and Canon were costly, and Olympus had problems; that left the Pentax K20D.
That was my thought process: where do I wanna go, how do I get there, and can I afford it and be happy? I ignored marketing hype. I read tech reviews and user ratings, and especially user complaints. I drew graphs of happiness vs cost. I did not start off biased towards Pentax, because in 50 years of shooting, I'd never owned or used Pentax. If anything, I was biased towards Sony, then Olympus and Nikon. But careful analysis led me to the K20D, and I'm quite happy.
(My codemonkey training included Top-Down Structured Analysis. Learn what outputs are desired and what inputs are available, then figure how to get the former from the latter. Break each big problem down into smaller chunks. Analyze from the top down; solve from the bottom up. It's a good approach to many questions.)
Yes, better low-light dSLRs exist, but you can learn how to shoot well in low light with just about anything. Use flash, faster lenses, tripod, patience. Practice, practice, practice. Keep in mind that, with film, if you want more or less or different sensitivity, you buy a different roll of film. With digital, the camera IS the film, and costs rather more to replace. Also keep in mind that Canikony exploit their high-end gear as come-ons to tempt unwary n00bs to buy their entry-level crud: "Hey, if I buy this X-1000-Z, I can sell pix to National Geographic and Arizona Highways and Hustler, too!" Yah, sure.
