Will this lens fit on my Nikon D3000? - 1

I want to purchase the AF Nikkor 70-300mm f4.0-5.6G lens. Will that lens fit on my camera, or is it just too big? If it doesn't, which similar lenses would work? How can you tell if it would fit?

It will fit on your camera. All Nikkor Lenses will fit on your camera, Nikon hasn't changed it's lens mount in almost 40 years I think. Just line up the markers on the lens and the camera, and twist to lock.

To work properly with all camera features it needs to be an DX lens. The lens you are asking about is an FX lens which in real terms its for a full frame camera, so your pictures will turn out having a black space around the edges. Most digial SLR cameras Nikon makes are in DX format (Cropped) sensor.

So yes this lens will fit, but it won't work correctly.

This lens will fit on your camera as most Nikon lenses going back 50 years. However, since it's an AF type lens, it will not autofocus on your camera. You really want the autofocus feature.

Look for Nikkor (Nikon) lenses with the AF-S designation. This means it will autofocus on your camera. You may want to look at the Nikkor 55-300 AF-S lens for about $350. The 55-200 AF-S is around $200.

The other respondent is wrong about the DX/FX compatibility issues. This is a FX (full frame) compatible lens which means it will work with your camera which is DX (1.5x cropped sensor), in fact quiet nicely since the sensor in your camera is smaller than a full frame sensor. Means that you will have less distortion problems with this type of lens.

In fact, DX lenses work on Nikon's FX bodies, but the camera will automatically crop your images to DX sensor size so you won't get severe vignetting.

It fits, it's manual focus and it's a cheap lens with cheap performance. Save some more for a motorized sigma 70-300.
