Tamron 2x SP AF Pro Autofocus Teleconverter for Nikon AF-I, AF-D & AF-S
The Tamron SP AF Pro Teleconverter features improved optical construction, and is designed to be used with lenses that are f/2.8 and of focal lengths of 90mm or greater.
The 2x teleconverter (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6.
This teleconverter is not recommended for lenses wider than 90mm, e.g. 50mm, 28-105mm, etc. However, full AF operation is still only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.
Note! When used with lenses with smaller maximum apertures (f/4 and f/5.6, for example), there will be little difference in image quality as compared with the standard Tamron teleconverters. When used with lenses wider than 90mm, the SP teleconverters can actually compromise image quality.
- Pro-series teleconverters are specifically designed and optimized for use with ultra-telephoto lenses (above 200mm) to deliver maximum resolution, contrast and color rendition without degrading any aspect of the master lens performance.
- Improved optical design of 4-group/5-element for 1.4x and 4-group/7-element for 2x. Relative illumination is significantly improved resulting in better overall contrast and resolution across the entire image field.
- Multi-coated elements result in crisper images.

I am a professional that uses Canon L lens only and was using Canon Teleconverters both 14x and 2x that I use extensively without a Problem. But, I have decided to go with the Tamron SP Autofocus 2x & 14x Pros.
Why? I have done extensive testing on the four teleconverters and have found that there is no noticeable difference beween like teleconverter. The only exception is the Canon's are heavier and longer and protrude into the lens but are not any better than Tamrons. Another professional friend of mine also looked at the results and was equally surpised.
Tamron's will work on more lens as they do not protrude into the lens like the Canon's do. Remember that lens will only auto focus if you are f8 or less (bigger)lens f-stop. If you add a 2x to an f4 lens it will not autofocus. I manually focus when I have a long telephoto lens on to get out to 800mm but this means with my f4 lens it is really now f8 so requires manual focus. Tamron has a very good little manual that explains all of this. Good luck, Howard

Bought it... Tried it...sent it back. The people at B&H were nice enough to let me return this lense no questions asked. Because of that they have earned a customer for life. Tamron has a good rep. but they blew it on this one. Tried it on a monopod, tripod, on every setting known to man. (Nikon D5100) The best results....I didn't get any. cropping on the computer yielded far better results without using the tC or spending the money. Lesson learned: Staying with Nikon

Comments about Tamron 2x SP AF Pro Autofocus Teleconverter for Nikon AF-I, AF-D & AF-S:
This is an excellent supplement if you own a Tamron lens. I have the 70-300mm and it certainly has pushed the need for an additional 150-500mm lens.

Comments about Tamron 2x SP AF Pro Autofocus Teleconverter for Nikon AF-I, AF-D & AF-S:
First, I wanted to give everyone a heads-up. The pictured item for this product (as of today 5/13/11) is white with a black rubberized grip on it. However, recently Tamron changed the style of the teleconverter to be all black.[...] As to my experience with the product, the quality and build seems great. I've always been impressed with Tamron as an alternative to pricier lens companies. I'm using it primarily with a Tamron 18-270 PZD VC lens and the extra reach is incredible (at full tele with the D90 crop factor the lens' 35mm equivalent focal length is 820mm!!). When attached to my Nikon D90 body, however, the Vibration Compensation (VC) is a little spotty. It will work MOST of the time and stabilization efficacy doesn't seem to be affected, but on occasion the VC will just no longer activate. A very quick and easy fix for it is to just semi-detach and then reattach the lens/telconverter (don't have to fully remove) and voila the VC works again -- if only for a little while. Strange issue, but not too much of a hassle.When I contacted Tamron about the VC issue the representative informed me that it is because this teleconverter is "not compatible" with any VC lenses (at least Tamron ones), which perhaps explains the sporadic functionality. However, I usually understand "not compatible" to mean "doesn't work ever" but my experience is that the VC on my 18-270 PZD VC works just fine -- just when it's in a good mood. Overall, I'm very happy with this teleconverter. Don't expect AF to work unless you're using it with a very fast lens because it attenuates the amount of light (basically, if your lens is a f/2.8, adding this TC makes it an f/5.6). And to my knowledge the majority of AF systems don't function well or don't function at all at apertures smaller than f/5.6 (feel free to correct me in the comments). That said, AF did work under bright conditions, so again it's not that big a deal. In short, you get a lot of extra reach, but you have to give up AF and VC sometimes. But there's no free lunch in the world and unless you want to drop a few grand on a fast tele lens, this is a good alternative for ~[$]. But realistically if you're expecting to hand-hold an 800mm lens then perhaps your expectations need some reconsideration ;)

This is a great product with multiple uses. I have used it for wildlife photography as well as portraits. To be able to put it on an 80-200 and have a good quality 400mm lens is great, and especially for the price. It make auto focus very finicky but besides that it is a great product

it works but no AF on Tamron 70-200F2.8 ... a red sticker also confirms that Tamron knows of the issue. Sad that nobody would specify so on their websites.
