In other words (like I suspected) Nikon's D800 completely blindsided Canon.
So not to loose face and stem a possible hemorrhage of photographers into Nikon's camp, Canon releases disinformation rumors.
First: We may be releasing a high MB camera soon.
Second: Uh, we STILL haven't released a high MB camera because it's taking longer because it's neeeewwwwwww sensor technology.
Third: We have to upgrade the lens first.
Last one really amuses me because it implies that Canon lens suck compared to Nikon. Nikon didn't need to upgrade their lens for people to instantly see massive benefit from the D800. Will a whole new slew of Canon lens be needed to see a difference with Canon new high MB camera?
Keep in mind, a lot of nikon users have complained about softness with high-MP sensors. Also keep in mind that Nikons FF sensors are LOWER density than Canon;s 18mp APS-C sensor, and that includes the D800's 36.3mp sensor. Canon is not just updating lenses to support 47mp FF senors...they are paving the way for the next decade or two of sensors. If anyone thinks we are going to stop at 50mp, I think they have another thing coming....I bet we see 60, even 70mp sensors within a decade. Canon glass has been good enough for higher density sensors than the D800's for years. The new Mark II generation of 4-stop IS lenses will be good enough for sensors 10 years from now (with possibly an IS update and maybe a Fluorite element mod to reduce weight five years from now.)
A lot of Nikon class (and I mean most of it...there are only a very few exclusions here) is not quite or only barely good enough for the D800. Nikon is really due to upgrade a lot of their lenses to support higher resolution sensors as well. They just haven't gone quite as far as Canon did with the 18mp APS-C yet (except in the case of the D3200, which is a 24mp APS-C). If Nikon went for a 45 or 50mp sensor at some point in the future, which I doubt they will do for a few years yet, they would very likely be in the same boat as Canon.
Personally, I'll take Canon Mark II glass over anything else, including Zeiss or Nikkor, any day any time. It brings out the best in my still very high density 7D, and then some. The most phenomenal lenses I've ever laid eyes on, or had the pleasure to use. Light as feathers, AF fast as bats out of hell, and have the best IS one could hope for (imagine getting a 1/20th second hand-held shot out of a 500mm lens!)
