It's a well known and simple procedure. Sometimes there's no alternative but to use the Nikon tc-14e with a Sigma lens, as Sigma's own converters are notorious for not working with their own lenses. Kenko pro300 is a more reliable alternative but can fail to work on the odd camera/lens combo.

So do nikon deliberately do this to try to prevent people from using Sigma lenses with their TC?

Canon would never stoop to those levels

Probably to get people to buy AF-S lenses rather than the cheaper (and eventually obsolete) AF-D lenses, which won't AF even when attached to a modern Nikon tc... I doubt there's a Sigma factor involved in their design.


btw: the optical superiority of tc's matched to the lens are a bit of a fallacy these days, used to be the case but not anymore.

Almost all the old AF lenses will work on new bodies, but not all new AF lenses will work on old AF bodies.

I'm talking teleconverter to lens fit, not lens to body.

Fortunately Nikon have one-up in that all their cameras will AF when faced with less than f5.6 worth of light in front of them, unlike some cameras that have an auto-cut off

I have a hard time trying to work out which 3rd party lenses will work with my 10D so stuff like this just gets my back up.

It's good (in a strange way) to see that Canon aren't alone in being right royla pans in the neck when it comes to their (and others) lenses. It makes me feel a little less angry at them ;-)

There's not a problem using lenses with Nikon cameras, just when you add a dreaded teleconverter.

So do Nikon ensure that older Sigma, Tamron, Tokina, etc (NAF) lenses work on their newer bodies then? If so I could be tempted to defect next time I wnat to upgrade my camera body.

I tried to match up my Sigma 400mm to a Canon 1.4x the other day - it would need more than a file to make them fit, a hammer and chisel might do the job, though
