Erm... someone enlighten me, but I'm not quite sure how these JD power surveys work... do people have to actually prove that they are customers who own the things they're rating? Do they rate these cameras side-by-side, or just rate the ones they own? Or is this all anonymous and unsubstantiated? Can they vote more than once?
For anyone who's been over at DPReview and looked into the forums, you'll find people who claim that they bought a certain product and then go on that forum just to trash it, and many are found out as having never touched the product and being fanboys for a competing brand. Fortunately, such trolls seem to be largely absent here.
I, for one, find it fishy for a study to show the two leading, big brands recieving a 5 star rating in overall and the other three recieving a 2 star rating in overall.
Personally, as an honest customer, I find nothing dissapointing about the output of my Olympus E-330 at up to 12x16 at base ISO, and the newer models have considerably improved on even that, making higher ISOs and larger prints usable. I guess these "average consumers" unhappy with Olympus DSLR image quality must be printing 40x30 at ISO 1600 and up.
Also, it's noted that sony and pentax also recieved the same low rating for "picture quality," so apparently it's not a format-related problem. Based on the fact that sensors in many previous nikon, sony, and pentax branded cameras have been shared, I'd venture to say that it's more of a market share-related issue we're seeing here. And we all know how important that is to image quality.
It's good to look critically at any review. Wasn't it the Standard & Poor that had not seen the housing bubble and the credit crisis coming, and burned many people with their judgements?
So, all fine, plus a grain of salt.
I guess it's up to every photographer to decide which tools he works best with.
I can imagine photographers feeling so comfortable the way Olympus builds cameras, that they don't care about certain loss of quality.
Those same people may also own a Leaf or a Phase One, depending on the job.
Many are enamored with reviews, as they think they can get the perfect camera the first time.
Not possible. And if all cameras had the absolute same image quality, you'd still feel better with one brand than the other just because of handling.
