I want to purchase Tele converter ,atleast 2x. i am in to Birding

Depends on what you want. Making you lens a 36-110 mm. with the loss of two Aperture steps, can hardly be what you want. Knowing most camera's can't use AF, once the Aperture exceeds 5.6.
My guess is you have the lens that came with the camera, so it is 3.5 to 5.6 to start with. That will become a 36-110 with f 1: 5.0 to 11.0.
In normal words, the lens almost certain can't be used with autofocus, above 55 mm, because there it it will go beyond the 5.6.
These 2X tele convertor would be great on a tele lens with a wide aperture like 2.8. Perhaps you better spent some money on a cheap canon tele lens then on this convertor.

have you tried cleaning the lens contacts with soft cloth?

ifnot do that.

is there no problem with out the lens in there?

Melissa. The 2X-1 is for use on a M42 screw connection, like on Pentax The 2X-3 is for Nikon.

There are a lot of adopter rings available. But most will turn the combination into a MF lens. Most non Nikon tele convertors, only can be used in MF when put on a Nikon camera, so I don't think you lose a lot when you find a Soligor Nikon adopter ring.

The SX1 has an amazing 20X optical zoom. The teleconverter will allow to get pictures if the camera zoom is not fully on 20X. It means that you can't get a full 40X zoom images, but a 30X maybe. I don't why canon has this problem.

This is a lens for Sony/Minolta cameras. It is not compatible with the Nikon D90. Hence a Teleconverter for Nikon will not work on this lens to mount it to a Nikon D90.

aturnbull1,
any good camera store or repair shop should have a 2X tele converter for MZ-60, new or used. i would try e-bay also.

A 2x tele-extender will rob you of two stops of light. This is simply a matter of physics: you're looking at only one quarter of the scene, so you'll only get one quarter of the light.

You specified neither the camera body you're using nor the lens you're using the tele-extender with. Most Nikon bodies will not autofocus with lenses slower than F/5.6. (Actually, they might, but F/5.6 is what Nikon specifies.) With the two-step penalty, a lens would have to be F/2.8 or faster in order to autofocus.

The solution is to either get a faster lens ($2000 or so) or to switch off the autofocus and go manual.

AS you have found out, the Maxxum AF mount and the MD mounts are much different. They do make tele-converters that allow the use of MD (non-AF) lenses on a Maxxum series camera. You would still need another adapter to make the MD Tamron converter work,

any type of filter of anybrand, also any type/brand of teleconverters can be use with s6500 as long as it's 58mm
