New to UHH. Wish I had found it sooner. Can't tell you how
much I've learned. Thanks to all who contribute useful info.

I have a Nikon 5000 & 7000. I have the following lens.
10-24 Tamron, 18-200 Nikon, 50 Nikon, 70-300mm Tamron.

So does a teleconverter multiply the distance by it number ie:1.5 or 2.0 or whatever? And where would I get it and will it work on both of my cameras.

You can get a teleconverter from a plethora of retailers, for almost any price and quality you can think of . You might want to consult a top retailer like Adorama or B&W for compatibility and feature issues. Once you have installed the converter, remember to factor in the 1.5x telephoto effect caused by the reduced sensor size in your cameras. If you place a 2.0x converter on a 200mm lens, your convertor will convert the focal length to 400mm. Multiply the 400mm by 1.5 to accommodate the smaller sensor and your final virtual lens length should total 600mm. Be sure to check these figures with your local expert. I could be wrong.

Teleconverters are either 1.4 or 2.0 and yes it will multiply by the same factor. You will lose 1 stop of light with the 1.4 and 2 stops with the 2.0, so unless your using a fast lens they really only work in bright light situations. Be sure to get 'auto' teleconverters too, so you retain your auto functions.

Bofferman,

A teleconverter performs several tasks when attached between your primary lens and the camera body.

1. It increases the Focal Length of the attached lens by the amount stated on the Converter body.
2. It contains a glass element to provide the conversion, and this can introduce lens distortion in the captured image.
3. Because it limits the field of view (teleconversion), it will reduce the quantity of light striking th sensor. Depending on the quality of the converter it may be as much, or more than the values stated on the lens barrel.

It is generally thought advisable to have camera, teleconverter, and primary lens attached to a tripod to avoid camera movement during exposure.

You may find you have to boost up the ISO sensitivity to stop subject motion, and to aquire the Aperture setting you desire.

With the lenses you have, a 1.4X will be working the best for you with the Tamron 70-300. I recommend Tamron converters. You will probably lose AF and have to manually focus. A good monopod would also be a good investment with this.

Look at the len's manual - it will tell you whether or not the lens is compatible with a tele-converter.
I have a Kenko 2x and it works with Nikon lens that are not supposed to be compatible with a tele-converter.

If you buy one, make sure it is returnable, in case you don't like using it.

I quite agree. One additional point, because the extender/multiplier increases magnification without increasing minimum focus distance they can be very useful for close-up work.

An issue is whether a specific teleconverter will physically fit a specific lens. For some lenses the back elements protrude so that a teleconverter can't be attached.

Nikon makes 1.4, 1.7 & 2.0 teleconverters but they won't fit all Nikon lenses. I believe www.nikonusa.com has a list of its lenses that accept teleconverters. I can't comment on Tamron lenses and teleconverters except they are often physically different.

It would be best to confirm compatibility before you buy!

You are going to lose light with a teleconverter and (even if it fits the lenses) won't do you much good. Taking a look at your lens kit, I think you should have everything covered for normal shooting. If you're going to the Rockies to shoot big horn sheep, well, I would just rent a lens then!
