My longest lens is the Nikkor 70-300 VR 4.5-5.6, which is rotates between my DX bodies. This gives me the equivalent of 450mm. If i could add a 1.4 teleconverter that should give me over 600mm for shooting birds in good light. Can I add this TC to this non-pro lens?

I've used a 1.4 teleconverter with both my 70-300 and my 300 prime Nikor lenes. However, due to the lens construction I have to use different TC's with each of those lenes, make sure you use the TC which will mate with that particular lens

Go to nikons web site n search teleconverters and it will show a chart as to which lens will work with a particular lens, my 2x sigma matched to my 150-500mm also works with my tamron 70-300mm.

I'm sure if you check the Nikon web site it will tell you which lenses the 1.4x is compatible with. I'm pretty sure it's not compatible with your lens and that simply means that it won't autofocus. Most variable aperture lenses aren't compatible with teleconverters. Some aftermarket teleconverters might work but I can't attest to their quality.

The Nikon teleconverter has a front element which sticks out past the mount. If the back element of the lens is not sufficiently recessed, they will touch, which is very bad. Sometimes "not compatible" means "physical collision".

Thanks all. I revisited the Nikon website and found the answer, NO. When I first checked the only chart I could find was for the Prime Nikkors.

Kenko's TC's will work with that Nikon lens; at least my 2x does.

I purchased the Kenko 1.4 converter to use with my 70-300 NIKKOR. I had no problems with the combo. Birdshots were awesome. Camera and lenses worked just like they were supposed to. Bought mine through B&H. They also confirmed that the converter would work. Dave ...

The Nikon branded Converter probably won't work, but aftermarket brands will. Go to "Search" at the top of the forum page and type in Teleconverter for Nikon 70-300 VR 4.5-5.6 and you'll find many suggestions.

I also use a Kenko 1.4 converter with my Nikon 70-300 MM lens and Sigma 150-500 MM it works great

As other posters have said your combination of lens and TC may or may not work physically
The real question is whether or not a TC with a particular combination of camera and lens does any good, A recent thread challenged anyone to produce a pair of pictures with/without a TC in which the TC improved the real resolution.
What a TC does is to magnify the optical image projected on the matrix of cells in the sensor (cropping the resultant picture and making it darker)
If your camera already has sufficient pixels to fully resolve the sharpest portion of your image, then optically magnifying it does not help- you would get the same result by digitally cropping/zooming

On the other hand with a low (but beautiful) pixel camera such as the D4 with a good prime lens the opposite may happen and the apparent resolution would improve with a TC

Conclusion: Optical magnification using a TC may or may not improve your ability to read that last line on the eye chart

Along the same line, switching your lens from a FX body to a DX
does not improve the "reach" it only crops the image, exactly as if you had cropped the FX image in photoshop

A 300 mm FX lens and body has exactly the same reach as a 300 mm DX lens/ body. The FX is only bigger, heavier and more expensive with a wider FOV. above assumes both cameras have same technology and pixels per inch of sensor
