Well, I never intended it to be offensive...
In that case, let me say that you have a blind spot when it comes to sensor technology, and it's the kind of blind spot typical of a 16 year old high school student flunking out of physics.
Hmmmm...not offensive at all, right?
...DXO scores seem to be on the money, not just with the D800, but with all the cameras I have personal experience.
The GH4 scores mimic what I expected form using it for a few weeks before the score popped up.
Are you suggesting that everyone's usage pattern mimics yours? Speaking as someone who shoots a significant proportion of my images above ISO 1600, with a fair number above ISO 6400, I can tell you that DxO's Scores absolutely do not mimic the cameras with which I have personal experience.
That doesn't particularly bother me, because I understand the general nature of the bias in their scores (even if I don't understand the specifics or the magnitude of that bias, because DxO does not disclose their formulae). But it's unfortunate that many people accept their scores as generally applicable, when that's far from the truth. It's even more unfortunate when people support them without knowing (or caring) that they are equally biased.
If there is any system justification going on, it is on this forum, where no matter what any other manufacturer does, Canon are still the best.
And few see that that's that's going on. It's not a forum, it's a fan club.
Well, it's Canon
Rumors, after all...not Nikon or Sony or Photography Rumors. But still, I don't see that particular attitude very often here. What I do see are a handful of people who have decided (long ago or recently) that Canon is not the best system for them
, and come here to convince others that means Canon is not the best system for anyone
. Where is Nikon's PC-E 17mm? Why don't most Canon bodies (except the 1-series) allow spot metering linked to any AF point? Where is Nikon's handholdable 600mm f/4? Where is Canon's sensor with 13-stops of DR at base ISO? Where is Nikon's 1-5x super-macro lens? Where is Canon's sharp-to-the-corners f/2.8 ultrawide zoom?
A system comprises many components. Having one part of one component (the sensor in a camera, in this case) that is better than the equivalent part in a competitor's system does not make the system using that part 'the best'. Individuals make decisions about what is best for them
. As I stated previously, it's an objective fact that more people have decided Canon makes the system that best meets their needs, which is why Canon has been the dSLR market leader for >10 years, and remains so today.
People who argue that Canon 'is behind' and 'needs to catch up, or else,' as you are arguing, don't seem to grasp that simple, objective fact. Does that mean Canon can do nothing and remain on top? Probably not. But consider...Nikon chose to buy Sony sensors with better low ISO DR, an issue with which relatively few people have needs that aren't met by Canon's sensors. Canon chose to develop a groundbreaking new AF system for video/live view (a system subsequently incorporated into their Cinema line)...a system you praised. I think far more people will feel that an improved AF system adds to overall system performance more than improved low ISO DR.
Canon seems to be 'skating to where the puck will be,' whereas Nikon is playing catch up. For example, did you notice that Nikon is now using fluorite elements in their supertele lenses? When only Canon used it, Nikon said fluorite "easily cracks," but now fluorite's "superb anomalous dispersion properties...effectively correct chromatic aberration," and it allows "a more effective lens with less weight," (all of those are quotes from Nikon's lens glossary
). I guess Canon knew what they were doing when they first started using fluorite elements in SLR lenses...45 years ago
(in fairness, Nikon has used fluorite elements for many years in their microscope objective lenses, since fluorite transmits UV better than glass, an advantage for fluorescence microscopy).
Time will tell, of course, but for the past 10 years Canon has made the right choices to drive sales, and while they're predicting slight a loss this year, Nikon is predicting a substantially bigger loss.
