Nikon 70-300mm VR mount on Nikon D7000?

Hi, guy if a Nikon 70-300mm VR len mount on Nikon D7000 in the end of 300mm will it be 450mm as the len manufacture say mount on DX Nikon D-SLR and Nikon D7000 is a DX -Format CMOS any advise it much appreciated.

Due to a 1.5x crop factor. ( see http://en.wikipedia.org/...rop_factor ) you would have a field of view simular to a 450mm lens on a full frame camera.

Personally I don't pay too much attention to this. The d7000 is a fine camera and the 70-300 is a nice lens. With a dx camera you have the added bonus of using the best part of the lens.

In a nutshell without getting too technical, due to the sensot crop this lens will behave more like a 105-450mm in equivalent 35mm terms.

To work this out multiply the focal length on the lens by 1.5

In a similar manner that's why 'kit' lenses on DSLRs tend to be 18-55mm. This would be the equivalent kit lens on a 35mm film body 28-80mm standard zoom.

The only time you need to worry about this is at the wider end. On a 35mm or full frame a 10-20mm is super-wide whereas on a crop sensor you lose some of this.

For tele lenses though this is a benefit!

Yes it will.

The type sensor, CCD or CMOS does not matter. DX is DX.

Yup, its true since any focal range of the lens needs to by multiplied to 1.5x so 70x1.5 to 300x1.5 will the equivalent of your tele photo lens since you are using a DX cropped censor (that would be 105-450mm). Advantage is you get a longer focal range.disadvantage is that you don't actually get the wider end of the lens.
