The Vivitar 2x 7-Elements Teleconverter for Canon cameras is a precision optical component designed to expand your photographic capabilities. This premium quality 2x teleconverter, effectively doubles the focal length of the lens it's used with and maintains the resolution and contrast of any fine optic. A 7-elements teleconverter will deliver sharper images with more depth compared to teleconverters with fewer elements.The 2x teleconverter 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. Autofocus is not always maintained when using a teleconverter especially with slower lenses at apertures above f/4.

    Series 1 Teleconverter For Canon is rated 3.7 out of 5 by 18.
    Rated 5 out of 5 by from Better than you would think Yes, the autofocus doesn't work well unless you're in a well lit area. But there are some advantages that should be considered. First is that its inexpensive which means more money for other accessories. Second is you are extending your zoom range by 2x, making a 300mm a 600mm. Third is really only for astrophotography but its still a useful tool. I attached my telescope adapter for my dslr to the teleconverter and increased my magnification by 2x for astrophotography. It works pretty good especially for the price. My wife bought me the 600mm to 1300mm and I didn't like it. I prefer using this converter.

    Rated 4 out of 5 by from Good for the price I use this with my canon rebel T1i with EF 70-200mm f4L IS, Canon EF 50mm f1.8, and have tried it on my Sigma DC 17-70mm f2.8-4.0 OS. Works with each of these lenses. The teleconverter is non-reporting (does not report the 2 stop loss to the camera) so I retain autofocus on all lenses. However due to it being non reporting TTL metering works improperly. I have to under expose the scene by a full stop in order to get a proper exposure. As with all Teleconverters it does effect image quality and it does not work with EF-S lenses. Construction is solid with the only down side being the release button. The buttons tension is quite light making it easy to release accidentally if you're not careful. Over all it has a good price, good build quality, and decent image quality. This is NOT for someone who demands the best IQ out of each and every picture. But for the casual photographer like me it gets you the extra reach at a fraction of the price while still keeping usable IQ.

    Rated 5 out of 5 by from I would buy this again and recommend it I use this with a Canon 75mm-300mm lens. It is great at getting that longer shot by doubling the power. I was told that I might loose the auto focus, I did not. But it is best, at times, to use manual focus.

    Rated 4 out of 5 by from Good. I used this with my Canon EOS 7D and a Tamron 70-300mm macro telephoto lens. The results I can say are not bad, but given that Tamron is already slow in focusing (not an issue to me but if you are a wild-life photographer maybe), adding this piece will slow it down further in case you use the AF function. As for the quality of the image I can't say it is bad, but I'd say it doesn't change the original quality of the lens mounted on it itself.To see some comparison: @On left you will see the original shot @300mm, while on the right with this teleconverter (@600mm hypothetically). The blur is because I used manual focus, and my eyes tricked me with what I thought it's sharp.All in all, I can say it is a nice tool to have, and I'm waiting for a chance to use it with birds already.

    Rated 4 out of 5 by from Does it's job well. I use this before the 300mm L series lens and it works well. I do not notice any optical quality issues. Seems the same as it does without it. This takes my f4 to an f5.6, just as it says (+2 stops). At 600mm I don't bother with autofocus so I can't give any feedback on that. I see folks claim the autofocus is slow with this. I guess if you want autofocus go with something else but if you are comfortable with manual focus then by all means save yourself some money with this converter.

    Rated 1 out of 5 by from CANNOT BE ATTATCHED to CANON EF-S LENS Although there is no mention of compatibility issues on the website, you should be aware that the Vivitar Teleconverter CAN NOT be attached to EF-S Lenses of Canon EOS Cameras. There should be a note mentioning this on the website. Unfortunately, I will have to retrurn mine.

    Rated 4 out of 5 by from Great Product I used the Series 1 Teleconverter For Canon by Vivitar with a Canon T3i camera and a Canon 75-300mm lens, I was able to get some awesome pictures of the moon on July the 5th with it. The converter does exactly what I wanted it for pictures at longer distances. I had to use the manual mode on my camera when the lens was extended to about 500mm because the auto focus didn't work at this point, but it was very easy to setup in the manual mode and start taking pictures, if you are depending on using the auto focus on your camera all the time you will be disappointed, the auto focus will work up to a certain point, but with the lens extended full out, just switch over to manual and start taking pictures. I am still working on different setting to see just what I can get out of this product. I purchased this converter for taking pictures of wildlife and landscape and so far I am well pleased with it.

    Rated 2 out of 5 by from Does what it says just din't work for me I was trying to use with my 70-300 but was not happy with the results. Was not sharp as I needed and would not work consistanly with the auto focus. The faillure was as much the fault of my 70-300 as it was the teleconverter. It was well made just wasn't the fix for my problem. I was trying to double my focal length with out having to carrying a large telephoto lense. The return proccess was simple and easy and why I buy from B&H. To get the quality I wanted I went wiht a 150-600 and am very satified with the results.
