As for Pentax, Sony, and Olympus, these are all brands trying to keep up with the competition. this may be sort of true, but doesn't mean they are not quality products, the only reason canon leads in sales, is because they were the company with the forsite to sink money into digital in the beginning, had Minolta and nikon not dropped the ball it probably wouldn't be so, in the 80s and 90s minolta and nikon had the lead and canon produced some real junk trying to keep up with them..If you think about every major professional photographer, they are shooting with a canon or nikon. I challenge you to show us a list of every major professional photographer and a list of their equipment.Both of these brands offer 60+ lenses for any shooting situation you could ever imagine. If you're getting into digital photography and want an SLR look no further. it is a disservice to tell people that those are the only 2 brands worth looking at, not everyone needs 60 lenses, nor does everyone feel the need to use Canon, to believe they are a photographer.., that's like saying if you don't have a hummer your suv is worthless, there are many good options out there for people
while Sony may not have as long a list of lenses, there are many minolta lenses to be found, that work quite well on the sony dslrs and althought they are late to the game, all of the Sony's so far have gotten great reviews, and more and more reviews are stating that canon better watch out, because Sony is a serious player, We shoot Canon and won't ever touch anything else.
PS- Does anybody know where I can get a 300mm 2.8L IS USM lens for under $3500?? (new, it's the next lens on our list)
