Product Highlights
  • Effectively Doubles Focal Length
  • Optimized for Lenses Longer than 90mm
  • Fits Nikon AF-D, AF-I and AF-S Lenses

TheSP AF 2X Pro Teleconverter for Select Nikon Lenses by Tamron features improved optical construction and is designed to be used with lenses that are f/4.0 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/4.0 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.

This teleconverter is compatible with Nikon AF-D, AF-I and AF-S lenses. However, when using AF-D lenses, the autofocus function will only work if the camera has auto-focus capability. The current SP AF 2X Pro Teleconverters come in black only.

Note! When used with lenses with smaller maximum apertures (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. When using AF-D lenses the autofocus function will only work if the camera, has auto-focus capability. Tamron's 2x teleconverter is fully 100% compatible with Tamron lenses.

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.
Compatible with Nikon AF-S, AF-I and AF-D Lenses
Magnification 2x
Lens Elements/Groups 7/4
Compatibility Nikon AF-D, AF-I and AF-S Lenses

    I have a Tamron 70-200mm f2.8 VC AF lens. I also have a Tamron 1.4x Pro teleconverter. The VC and AF is not compatile with the 1.4x. I had read in a review that for Cannon, the 2x Pro teleconverter is compatile with VC and AF. I have a Nikon. I asked BHPhoto to put the zoom on the 2x Pro and see if the VC and AF work on Nikons. BHPhoto wrote back and said both VC and AF work. That was what I wanted so I went ahead and ordered the 2X. The 2X arrived and it turned out that AF does not work and VC appears to work at least sometimes. I was going to return the 2x, I wanted the AF to work. So if you are looking for a teleconverter that will work with a Tamron's 70-200mm VC AF on a Nikon, this one is not what you want.

    I decided to test out the 2x Pro and see how good it is.

    I've attached two pictures. The darker one was hand held Tamron 200mm f8 1/125 with AF and VC turned on. The the brighter one was with the 2x pro attached making it 400mm at f8 1/125 set on a tripod with VC and AF turned off.

    I took the two test images and cropped them to the same size and then resampled both to 20.5" by 13.6" at 240 pixel/inch. The result is that with the 2x pro teleconverter on, some details of the moon were lost and some contrast was also lost. It appears that the image with the 2x pro attached is sharper than without the teleconverter attached after the cropping and resampling. I came to that conclusion after blowing up the pictures and comparing the craters at the bottom of the moons since that is where most of the details are located. If you compare the two pictures without blowing them up, it appears that it is sharper without the 2x pro but I think it looks like that because some details are lost with the 2x attached.

    I in photoshop, I increased the contrast of the image taken with the 2x pro. That made it look better but it did not recover the lost details of the moon.

    I am leaning towards keeping the 2x even though it does not do what I originally thought and wanted it to do.

    So it appears that you will lose contrast, lose some details, but it will be sharper than digitally cropping. You can recover some of the contrast with post processing but not the lost details.

    AF Fails

      Comments about Tamron SP AF 2X Pro Teleconverter for Select Nikon Lenses:

      Nikon D7100 and Tamron 70-200mm f2.8 and this tele-converter is a great combination except it will not auto-focus, even after a B&H exchange. Neither converter would even attempt to auto-focus. Kudos to B&H customer service, they handled the exchange and eventual return with the attitude and professionalism I love about B&H.

      p.s. The tele-converter image is incorrect; it is all black and looks good on camera.

      Comments about Tamron SP AF 2X Pro Teleconverter for Select Nikon Lenses:

      I am a big Tamron fan and own two of their telephoto lenses. Unfortunately they are both "slow glass" so this teleconverter is marginally useful and can only be used with manual focus in good light. I will keep it because if you really need to bring in a distant object it helps, but resolution is not good. Perhaps I will buy a faster Tamron telephoto lens to use with it, but I'm not ready to spend the big bucks yet. I have posted results of my tests (made for my own information and not compensated in any way) on Flickr (I am vmi63) under the set "Tamron Lens Tests - January 2014". I have posted photos made with and without the teleconverter.

          Comments about Tamron SP AF 2X Pro Teleconverter for Select Nikon Lenses:

          I am an enthusiast - not a pro. Lured by the lower cost compared to Nikon's 70-200VRII. Got the Tamron 70-200vc and the Tamron 2x "SP" teleconverter together. I wanted a better lens in this focal range and also the reach obtainable by use of the teleconverter. AF absolutely did not work with the Tamron lens on my D800. If it does not work well with the same manufacturers lens, what is its facility? I had to return the first teleconverter because it had a terrible connection to the Tamron lens. Snug to the camera body, but loose and flimsy to the lens. This is the so-called "SP" Tamron teleconverter. The second one had the same problem. Also, the pictures are worse than my Nikon 70-300 that the Tamron 70-200vc was to replace. Tamron should not tout this teleconverter as special or even adequate, and should not sell it. I returned the lens as well as I cannot get the reach I want with the lens alone. The lens is a good lens. Not great. I did my best to save some money. Believed the good reviews and disregarded the bad. I wasted lots of time with trial and error. I now have the Nikon 70-200VRII and the Nikon 2x Teleconverter. They are both stellar. I am glad I went through the process, as I am now certain that I cannot possibly do better than the Nikon. I think you are fine if you buy and like the Tamron 70-200vc. Its a good sturdy product and pretty sharp. Coupled with the Tamron teleconverter seriously degrades it facility. This is my experience. B&H is great to work with as usual.

          I have a Tamron 70-200mm f2.8 VC AF lens. I also have a Tamron 1.4x Pro teleconverter. The VC and AF is not compatile with the 1.4x. I had read in a review that for Cannon, the 2x Pro teleconverter is compatile with VC and AF. I have a Nikon. I asked BHPhoto to put the zoom on the 2x Pro and see if the VC and AF work on Nikons.

          affordable alternative to dedicated lens

          By Arie

          from Houston, TX

          Comments about Tamron SP AF 2X Pro Teleconverter for Select Nikon Lenses:

          I mostly use my 80-200 f/2.8 AF-D lens and it's usually long enough for most work. I've debated about getting a dedicated long telephoto like the new 80-400mm f/4.5-5.6 or the Sigma Bigma, but I know I would miss having a great f/2.8 lens more than I would miss the range. (That's why I traded in my old 70-300 VR for the 80-200)

          I only need the very long telephoto for occasional nature shooting and didn't want to invest $2600 AND have the 80-200 so I tried this teleconverter.

          First time, I was disappointed because my shots were blurry and I had a very narrow DOF. 2nd time, I took my heavy tripod, used at least a 1/500 shutter speed, and stopped down when needed to and got good pictures. Stabilization is everything when you are working with essentially a 400mm f/5.6 lens.

          2 stops of light is a lot so don't stop down much. Also, I was disappointed that the EXIF data didn't reflect the teleconverter so it still showed something as 200 f/2.8 instead of 400 f/5.6

                    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 SP AF 2X Pro Teleconverter for Select Nikon Lenses:

                    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

                                Comments about Tamron SP AF 2X Pro Teleconverter for Select Nikon Lenses:

                                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

                                        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.
