Using a Teleconverter

I have a 400mm Pentax "A" lens and a 2x teleconverter. I know that I have to have the Pentax K10D set on "manual focus". Do I havehave to rely on my manual settings for the aperature & shutter speed? I assume that the camera will not set the aperature/shutter speed. Should I set my dial to "M"? Thanks in advance.

With a high enough ISO and a bright sunny day with a shutter speed of 400 or less shooting off a tripod it might even auto focus. Otherwise manual is the best option. You didn't mention apature, that makes a difference also.

it depends on the kind of teleconverter you have.

there are fully manual ones but also ones, that support AF and have aperture couplings.

what does the backside of the teleconverter look like ? if there are little electrical contacts that match the bayonet of your cameras body, it most likely transmits the aperture info to the body and you can use the lens/teleconverter in all shooting modes.

if there are no contacts you have to set the aperture on your lens and use m-mode and stop down metering.
