I was reading a post a while back from someone who stacks teleconverters. They said they had stacked a X1.4 on top of a X2. I have those two converters and decided to try it on my f2.8 lens (everything is Nikon) and the converters will not stack, is there something I’m missing? Well obviously there is but just what is it?

I think it's a bad idea in the first place, even if you get it to work, the IQ will be lousy at best.

IQ really isn't all that important for what I'm trying to do. Thanks anyway.

So I'm some kind of "nut" because I'm attempting something different? Pretty judgemental for someone who knows nothing about what I'm trying to accomplish.

It wasn't a personal attack it was a tongue in cheek comment, and as you don't say what you want it for and simply asked for comments, you received one.

If image quality isn't that important give it a try, you have nothing to loose. You will loose a few stops of light, but now days a few stops up in ISO won't degrade an image that much

Nikon TC cannot stack because of their construction, but Canon TC do Artie Morris stacks TC all the time on his long Canon Lenses

don't let the snobs stop you from experimenting. some of the hi-end teleconverters won't stack. however kenko,pro-optec, and vivitar to name a few will. i stack a vivitar 1.4 and a pro-optec 2.0 on my minolta 200mm f 2.8 G lens with great results and you keep auto focus. i also stack two 2.0's on my 200mm f4.0 pentax medium format lens ,you loose auto focus but the images are still great. if you look at the postings under my name you will find some samples. we are all about trying new things,but sometimes it's hard to soar like an eagle when the turkeys are trying to pull you down.

I didn't see a request for comments, just information. Tongue in cheek is not helpful information.

besides any other impact, if you could stack teleconverters, chances are your lens will no longer autofocus.

There's a say that goes something like this, "just because you can do something doesn't mean you should do that something".

The reason may be that you have to assemble camera, lens and teleconverters in the right order. Look for information about in what order you need to assemble your gear.

I highly support your experiment, which ever the reason for it is. Creativity and new ideas are the basis of evolution.

And there is way to much negative bullshit being said about the use of teleconverters. There is an interesting topic here on the forum that in a very simple way proves that teleconverters can be very useful in the hands of skilled photographers. Look here: http://www.uglyhedgehog.com/t-135965-1.html, or here http://www.mnh.si.edu/exhibits/natures-best-2012/photographs.html to go directly to the photos. If you follow the link to the award winning photos and check the info about settings and gear used for each photo at the bottom of the text section to the right of each photo you will see that some of those award winning photos were taken using a 1.4x or 2x teleconverters.

So go on and good luck!!

P.S.

Decided to make a list of the pairs of lenses/teleconverters used on this Smithsonian award winning photos.

Canon EF500mm f4 + 1.4x
Nikon 600 mm f4 VR + 1.4x
Nikon AF S VR 600 mm + 1.4x
Canon 300 mm f2.8 +2x
Nikon VR 70-200 f2.8G + 1.4x
Nikon AF-S VR 200-400 mm f4 G VR IF ED + 1.4x

So now we have chapter 1 of a list of combinations of lenses and teleconverters that can deliver award winning photos :D

Have you tried both ways of stacking? If the 1.4 won't fit onto the 2, will the 2 fit onto the 1.4? If both ways won't work - then looks like that is your answer.

Here is one I took with a Canon 300 f4 stacking a 2X and a 1.4. This made the combo MF only.
The first is full size frame resized only and the second is a crop. So obviously you can see that the eagles even with the stacked extenders were quite a distance away.
Not great but it can be done.
