I have nikon 5400.
when I put Olympus 1.7X

Then autofus will work or not?

Is it better than nikon 1.5X. Since 1.5X is small in zoom and expensive. :roll:

Thanks

Using a telephoto adapter will not affect autofocus. The camera doesn't care about the extender as far as focus is concerned since it only senses contrast differences. The "distance" at which you can focus will be affected.

The TCON-17 Olympus 1.7x is a very good optic. Probably equal to the Nikon in every way except that the Nikon lens may screw directly to your camera (I don't know this for sure) but the Olympus has a 55mm thread on the ocular side which will need to be mated to your filter threads or adapter.
