Nikon introduced a new SLR today. The Nikon D7000 slots between the existing D90 and D300s DSLR bodies. The following features are on the new camera:

• 16MP DX-format sensor with high ISO capabilities
• 100% coverage viewfinder
• Weather sealed, magnesium alloyed body
• Full 1080p video capability
• Twin SD card slots

It should arrive in stores at the end of October. A full hands-on preview is at dpreview.

Nikon unveiled two of it’s anticipated cameras today, the D300 and D3000.

The D3000 is aimed at first-time SLR users, it is similar to the D5000 but loses the foldout LCD, and gains a revamped menu system that will be a boon to beginners, but a bain to more serious photographers.

More interesting is the D300s, which adds 720p video capability to the D300 and an SD card slot. This camera is not going to be a large upgrade for existing D300 shooters, unless you’re dying to shoot video.

Nikon also refreshed two of their popular lenses, the 70-200mm F2.8 and the 18-200mm F3.5-5.6 VRII.

After a series of leaks last week, Nikon just made official the new Nikon D3x – their new top-of-the-line digital SLR camera. The D3x is a D3 with a new sensor featuring a 24.5 MP full frame picture size. Full details are available at Nikon USA. Various blogs also are carrying info: DPReview and Ken Rockwell. And yes, if you have to ask, you cannot afford it ($7995 USA MSRP).

I was wondering how my current (and discontinued) DSLR stacked up with the newest and greatest prosumer camera that Nikon offers when it comes to ISO Noise. It’s a tough comparison since the D50 is such and old camera and is only 5MP. the D300 has a 12MP sensor.
