Their statement that the 5D-II was ,"Quite possibly the most popular and influential DSLR in history." is patently ridiculous!!!! No, it has never, EVER been "popular." In both Canon and Nikon brands, full-frame d-slr cameras comprise around 5% of total d-slr sales. The 5D series has **always** been priced well,well above the purchasing price point of the vast majority of shooters, hence the normal M.O. in the 5D series: introduce at $3,499. After a while, offer rebates. Then drop price to $3199. Then offer rebates to move more stock. Then drop price to $2999. Offer occasional rebates. And a very,very slow,gradual decline in the retail price over several years' time. Meanwhile, the camera companies sell millions of $899 bodies. Those are the "popular" cameras.
"Popular"??? The 5D-II....uh...no...written about, yes, a lot. But in actuality, a very,very poor seller. Only the most-serious users have been able to afford a 5D camera. The "most-popular" and influential d-slr in history??? Stepping away from the hyperbole, and using an accurate and proper definition of "popular", the consumer models like the FIRST sub-$1,000 d-slr, the original Canon EOS Digital Rebel was a huge seller, and got many people into d-slrs and away from film SLRs. The original, sub-$1,000 Nikon D70 was popular, but the Nikon D40 was Nikon's single largest-selling d-slr EVER...for a long,long time...
In Canon, the "most-popular" d-slr??? Not sure, but it surely is not ANY of the 5D series. Again...sales figures show that the full-frame Canon and Nikon bodies make up only around 5% of the sales of d-slrs...just look at the cameras listed in the profiles of TPF members...mostly the "top" members are the ones who can see their way clear to buying a 5D series camera...
