Will it work with Nikkor 4.5 70-300 zoom? Or 55-200mm zoom? The 2x tel does not.

I just read a comparison review between the Sigma 1.4 TC and Nikon 1.4 TC, from a very reliable reviewer. According to his extensive tests, the Sigma TC only worked with Sigma lens on the Nikon, and the Nikon TC only worked with Nikon lenses on the Nikon. He strongly suggested matching the TC brand with the same brand of lens.

I don't know and my earlier point was that, apparently, Amazon doesn't know even though Sigma data clearly spelled out compatibility. So it is up to you to research the Sigma web site to determine the compatibility your self.

No, it will not. It works just with a limited number of SIGMA lens. Have a look on the SIGMA website. It does not work with any lens of different company (Nikon, Canon, Pentax ecc.). Better: it can increase magnitude of 1.4 but you will loose both autofocus and automatic exposure. Frankly speaking, I use it (not frequently) together SIGMA 300 mm f: 2.8. The autofocus is not very precise, slow and the quality of the photos is not fantastic considering the whole amount of money that the lens (both) costed. Regards

Nikon designs it's lenses so that if the widest zoom is under 70mm, they will not work with the teleconverter, whether its Nikon branded or not. I would not recommend using the 70-300 with it because of the loss of light. You also may not be able to autofocus at your longest zoom because the lens will have a widest aperture greater than f8. I never use this teleconverter due to the major reduction of image quality (I have a 70-200 2.8). The only real use for it is on the long primes like the 300 or 400 2.8 because it won't degrade image quality as much. In short, get good glass, not a teleconverter.

Sorry this was about a Tamron AF 2X Teleconverter, not Tamron lens. This teleconverter did not work on my Nikon D7000.

[fixed incomplete answer]This teleconverter should work, yes, but it will have a number of important drawbacks:(1) It change the effective aperture range of your 70-300 from f4-5.6 to f8-11 wide open. This will disable auto-focus on most Canons and the smaller apertures can make it harder to manually focus (at least with the optical viewfinder).(2) The increase in focal length can magnify any softness (typically, at the longest end depending on the quality of the lens) and may decrease the apparent effectiveness of IS image stabilization.

Big issue on using teleconverters is lighting. if you don't have good lighting then no. also the speed of your focus has an impact in performance. slow autofocus and you camera will hunt. I ha d a sigma 70 - 300mm lens and it did ok. but my tamron is so much better. especially with teleconverters. one thing the keep in mind. your f factor with change with these.so an f4 be much higher. hence lighting issues.I have even stacked them with mixed results.I have a nikon D3100 with 2 nikon lens, 18-50mm and 50-200mm, and a tamron 70-300mmand 2 of these teleconverters.

I ordered Tamron 1.4x for my Nikon. I have not had any problems with the Teleconverter. But realize that I made sure it was for a Nikon not Canon.

It will only work in manual focus mode with the 50-500mm (i.e. you'll have to focus the lens manually). Like any other 2x converter it will not only double the focal length, but also decrease the aperture by two stop making the lens too dark for any camera to focus automatically (i.e. f/6.3 -> f/18 @ 500mm)!The camera autofocus only works on lens faster than f/2.8, like the 70-200 f/2.8 (or 120-300 f/2.8) for example with this 2x teleconverter

I'm using the 2x converter with that exact same lens on my Canon Rebel T3. It works fine, but I have a hard time getting it to auto focus. It keeps going in-and-out of focus and runs the battery down in about 5 minutes of trying. I think this is more due to my shaky hands and the extra weight of the converter than anything. Tripod might solve the problem-----haven't tried that yet.

Hmmm... Not the one I bought... I purchased the adapter for NIKON (old school D70s)! BUT... According to Tamron, the tele-converters are compatible with Tamron lenses. Keep in mind that at extreme close-ups, focusing is slow and spotty - Especially in low light conditions. If you can live with that, then these are great! Remember to use a tripod for extreme close-ups. Movement is highly exaggerated especially with slower shutter speeds. Hope this helps!

No this is to increase the zoom for macro photography. It does not work with a telephoto lens, the camera will not be able to focus. You would need to look into getting a telephoto extender

No this may not work and may even damage the lens due to the construction of it. It is supposed to go with 70-200 2.8 VR / VRII and similar PRIME lenses that has the built and structure to accept it. Event if it can go with Nikkor 18-300 VR practically it will become useless due to the multiplication factor and how dark it gets after applying the TC and the image will be soft as an end result.

I was using it with my Nikon Macro lens as well as several of my Telephoto lenses. Zooming the lens will work, however the autofocus from the camera does not connect to the autofocus in the lens. Same goes for any image stabilization requiring power, and camera controlled aperture. The aperture can be controlled with on-lens selector or the less accurate selector on the adapter for lenses without that feature. Should work with all current Nikon lenses though.

Yes, it will. Please note that the TC will likely cause autofocus not to work (you will lose 2 stops of light). Also, the Kenko 2x TC is not a very good teleconverter so any images will be of extremely poor quality. Finally, if you have both lenses that you listed, it would be absolutely pointless to put any TC on the 18-55mm (that's why you have a 55-200mm). In short: Bad Idea!

It should work with all Canon super telephoto lenses. Canon's website or the lenses manual will confirm this information. It works with my 70-200 f2.8.

My 2x2 telephoto lens fit my Nikon 70-300 lens ok, so i dont think you will have any issues but I would double check for sure before buying. Sorry that wasn't very helpful.

Sorry, but it is not compatible with the lens. You generally need a 2.8 or larger (smaller number) aperature lens. You should go on the Nikon websiteand check the teleconverter compatibility chart before buying a teleconverter or lens to use with a teleconverter.

I have the same lens & teleconverter and it works perfectly. Good luck hope you enjoy this setup.Wayne

The short answer is no. I know that Nikon's 2x will not work with that lens because I have it myself. I also know that the Sigma teleconverters are specifically designed for Sigma optics. But beyond that the Nikon 70-300 is not sharp enough, or bright enough, to benefit from a 2x teleconverter. Yes, you might get a fuzzy 600mm out of it, if it would even attach without damage, but you would loose autofocus and your widest aperture would effectively be f/11!
