Before I start this thread I'll make it clear that this is a swipe at reviewers who have allowed bias to colour reviews, and not at camera manufacturers in any way.
The Nikon D7000 has received some glowing reviews to the point that some have stated that it's almost as good on noise as the D3 and yet I'm hearing so many stories from people who have bought this camera, that in practice it does not live up to the hype.
I don't believe that this is a problem with the camera, but with reviewers who have so over egged the pudding, that the reviews they have written have been downright missleading. This is helpful to no one, especially Nikon when buyers are dissapointed, nor to buyers wondering why they can not achieve the kind of results which the reviews are claiming.
For a long time I've been aware that a few dinosaurs who were comitted to Nikon in the days of film have been unable to accept the change to digital, and retain such an affection for one brand that they are unable to produce an impartial, and uncoloured review based on fact.
Anyone who does not agree with me is biased!
That is just human nature. We often see people talking about using real world images to test a camera, which, in fact, can be unintentionally selected to hide defects or make them less apparent. There are often no established tests for cameras, so opinions are all we have. For example, we hear that AF is fast or it is slow with a lens. How do you measure it? Its a function of lens, body, subject lighting and contrast, and probably more.
As someone who has had to conduct lab testing for use by some very technical and particular customers, I eventually learned to separate facts and opinions in my conclusions, and to justify my opinions. I have had to hold back a lot of opinions because there was no hard evidence to justify it.
We all see things thru a filter which is based on our experiences. If I've had a issue with a product in the past, I tend to be unforgiving when it comes to reviewing it. for example, I have had four sigma lenses that were made to be EF compatible, but did not work on DSLR's because Sigma did not understand the Canon lens communication adequately. Even now, I avoid Sigma, and when I see comments about poor autofocus accuracy, it just reinforces my experiences.
I'd agree with all of that, but one of the problems has been with noise, where some reviewers have claimed that the D7000 is as good as the D3 when it clearly is nothing like as good. Opinion is one thing, however exaggeration is something else, and is misleading. One of the complaints has been from a user trying to replicate low light results & then wondering what he's doing wrong when it's nothing like as good as the review had led him to believe.
If it was just a few reviewers opinions I'd never have posted the thread, however this is blatent over hyping a product which is adversly affecting the product experience of users, dissapointing them greatly.
