And yet...not surprisingly, the SL1, T3i, and T3 are all outselling the D3200 and D3100 on Amazon - so maybe Nikon should be embarrassed? Pentax and Sony? LOL. Judging by their sales rankings, consumers don't find them interesting at all. No Sony cameras in Amazon's Top 30 dSLRs. Speaking of 'dated', there is a Pentax at #29...but it's not the 'considerably better' K500, but rather the K-1000...I guess it's a good thing you can buy the film (!) for it on Amazon, too.The "bigger marketshare = better than" argument is pretty lame.
Seriously, anytime you feel like hauling out the "but Canon sells more!" argument ask yourself if Budweiser really is the best beer in America.
I didn't say 'technically superior', did I? In the case of the T3, it's most likely 'cheaper than.' And with apologies to any Bud drinkers out there, I prefer beers I can't see through.
But the point of the argument isn't which camera or beer you or I think is better, it's which camera or beer the majority of people choose for themselves. Look around your house - how many things do you see that, when you bought them, you thought 'this isn't the best product for me, but I'm going to buy it anyway'? Something may be better for you because it's cheaper, because your friends have one so you can ask them about it, because it has some feature that you particularly want, because it was available at the store you were shopping in, or a myriad of other reasons...but I'd argue the vast majority of time, when people make buying choices for non-necessary items, they're choosing what they believe is best for them.
"Best" is arbitrary and highly subjective...we define it for ourselves based on our own needs. "Most popular based on sales volume" is objective, and happens because a majority of those subjectively defining 'best for them' as that particular brand. In the case of beer, that's Budweiser...and for dSLRs, that's Canon.
Neuro, do you know if it is possible to obtain from Amazon, or from some other store, relative selling numbers? I assume retailers will not tell us how many cameras they sold last year, but maybe we can get them to tell us proportions (e.g., three 5D3 for every D800).
Maybe that lovely lady from Adorama (unfortunately I forgot her name) can tell us something like that.
I guess we could then have a better idea about market share.
