Nikon D3200 2x Teleconverter (4 Elements) + Nwv Direct Microfiber Cleaning Cloth.

Works great. The ONLY reason I did not give this 5 stars is I did not receive a "Vivitar" brand teleconverter from these folks but a import. It still worked and performed the same so not complaining but I have to say the picture is misleading. They obviously are making a great mark-up giving a knock off to their customers by doing this. Just saying if you are looking to get a Vivitar brand they slip you a "Mickey".

I tried it with my Nikon 18-200mm zoom. The autofocus worked inconsistently across the whole range. Constant hunting. Admittedly, it really isn't meant for use with zoom lenses, but some people seemed to have decent results.

I am happy with the product. I think I will be happier with it after I have used it more.

I wanted a multiplier to pull in some of those distant shots. This converter is excellent. Does what it suppose to with little fanfair. Im very pleased.

This product was supposed to work on my Nikon d5200 but most of the automatic features of my camera would not operate with this product. I had to return the converter and the seller was most cooperative with the return.

Did not work on AF

I use this with my Nikon 55-300, and my Sigma 150-500 lenses, love it! Auto focus works when lens isn't fully extended, manual focus after full extension. Works great.

Nice and clean shots. I use it with all my lenses now and it is producing get shots for it's cost.
