Nikon medium, 48 Mpixel, camera rumours.... text copied below, full article check out the weblink above...
------------------
We've been watching a few rumors drifting around in the past weeks regarding a possible new large format sensor from Nikon. A tip-off received yesterday by Nikon Watch ties them all neatly together.
The background: Nikon put out a print advertisement in Rangefinder magazine, regarding an announcement to be made at next year's WPPI (Wedding & Portrait Photographers International) conference. The teaser reads "Don't miss it. It's gonna be BIG!"
This subtle hint combines with a leak to Nikon Rumors which seems to show the specs of a new, larger sensor, called MX Format. The final piece of the puzzle comes from the afore-mentioned Nikon Watch: A reader tells them that the MX sensor will be a huge 48 x 48 mm. That's right, a decidedly old-school medium format square sensor. A big sensor that will sport a whopping 48 megapixels.
This certainly ties in with Nikon's current strategy. The D3 and D700 both have a relatively low pixel-count for their sensor sizes, resulting in some very clean low-light performance. Instead of just squeezing more pixels onto the same chip, it looks like Nikon might be keeping the same pixel density and just making the whole thing bigger.
Nikon Watch's source continues: The sensor will be similar in design to the D3 sensor and the camera itself will be able to use existing FX (full frame) lenses via an adapter. This will give a crop factor of 0.5x -- pop on a 50mm lens and it will act like a 25mm lens. It will also shoot rectangular pictures by cropping the image from the sensor, which means that you can choose either landscape or portrait orientation without actually moving the camera. Finally, the camera wil be cheap. Not D60 cheap, but a lot less than the current $40,000 offering from Hasselblad.
Now, allow me a little speculation if you will, in the style of the Scooby Doo gang piecing the evidence together. The official Nikon ad appeared in Rangefinder magazine. The announcement will be made at a conference for wedding photographers, a group who shoot a lot in dark places (churches and wedding receptions) and like to print very large pictures. Could we be looking at a giant rangefinder along the lines of the old Mamiya 7? A rangefinder with stratospheric ISO settings? It would certainly be a lot easier to handle than a big medium format DSLR.
We'll see. If this comes true (and we certainly hope it will), then it will be one more victory for the new, revitalized Nikon. Come on, Canon -- let's see what you've got.
