I’ve seen this debate come up a lot. Of course, it’s been rearing its head for a long time and will continue to do so far into the future, but it seems like I’ve been seeing more of it lately. Most people are pretty light-hearted when they talk about it. But almost everyone has at least some loyalty to the brand they’ve chosen. Partly it’s because cameras and lenses aren’t cheap and people have a psychological need to justify large purchases. Partly it’s about belonging to a “club.” There are a lot of factors.
My point of view is this: it’s a tool. I don’t much care what brand it is. The brand certainly doesn’t help me make photos. The brand doesn’t aid me in composition or help me see the world in a 4:6 ratio. I bought Nikon because the price/performance at the time I bought my original D70 (not the “s”) was better and the Rebel is too small for my hands. They both make excellent lenses and bodies. Both companies make equipment that far exceeds the ability level of 99% of their owners. Even though I have some money invested in Nikon glass, I’d switch without hesitation if I was looking to upgrade and Nikon equipment started to suck.
Anyway, I don’t mean to rant, but brand worship in general (and it isn’t restricted to just camera equipment) boggles me.
