Some people may hear this term used when discussing photographs and wonder how the “bokeh” is being used. Bokeh is a term used to describe the blurring of the background or foreground objects. Photomatters has a good piece explaining it and how to use it. You can view it here: http://www.photomatters.org/bokeh
So you have your new Christmas gift camera and it probably only came with a stock lens. Now you are probably wondering things like what kind of lens fits my camera? What size of lens should I use to shoot a child’s soccer game or a loved one’s recital?
Selecting lenses for a Nikon D40, D3000, D5000 or other DX cameras is more complicated than buying a lens for a $5000 Nikon D3x or other cameras. The difference is that in the DX models, Nikon has built the auto-focus motor within the body of the lens instead of putting it in the body of the camera.
Take a look at these two photos (courtesy of DPReview.com) and you can see the drive for the D80’s auto-focusing mechanism at the 7 o’clock position of the camera lens connector. That drive stem is missing from the D40 and it is missing from all of the DX version systems.
A word of caution…because I focus mostly on Nikon systems, I do not know what the equivilent is for the Canon system. So you should check with them about what their lower priced systems use for focusing.
So LensHero has come to the rescue by asking you for information about your camera, what you intend to shoot and then gives you suggestions on the lenses you should consider.
