Increasing magnification using a teleconverter with DSLR??

[mothershipuk]

Hi Guys,

Wonder if you can help me with this problem. The other night I had my scope set up in my back garden ready for another lesson in imaging and thought about increasing the magnification by using my 2x teleconveter on my DSLR. However, when I tried to take an image I kept getting an 'error 1' message (unable to communicate with lense.

Is there a way around this or perhaps another way to increase magnification at prime focus??

Speak soon

What camera, etc...?

Justin, I've heard of that... I think it's something to do with the TC trying to connect to the lens. The camera doesn't do it as the camera doesn't have the Connection established so knows the gear is manual only. The TC is expecting to have an Auto lens attached, and is telling the camera there is too, when there is no Auto communications the camera throws an error. Not sure how you'd get around that... You could try a barlow on the nose piece ?

I had the same problem and almost sold it as a result , but if you get a small piece of insulating tape and cover the contacts ON THE TELE on the camera side where the contact pins from the body would meet should work.

Worked for me

I had the same problem with my Canon 1.4X converter and as Beamish has said, the key is to isolate the connection pins in the barrel - on the Canon 300D, the whole thing just locked up!

Nice one guys. I have a cannon 450d. I'll try taping the contacts see if that works, many thanks.
