TTL wil work regardsless of the lens. No doubt in my mind - provided the flash and cord supports TTL. TTL does require a third wire, allowning the camera sensor to cut off the beam, when the sensor says: "Cut" But the lens may determine which metering type is used - only A-lenses or later (Correct me if I'm wrong) will allow matrix metering during flash exposure.

It sits on top of a tube fitted to a bayonet to screw-mount adapter. The camera is set to 'other than A'. All the image forming optics are external. So will TTL work? By the way there are flash pictures (made on film) here if anyone is interested: http://kotisivu.mtv3.fi/ahw/vort/index.htm There are two non-flash images for comparison -- its easy to see which they are -- this protist moves. These are not brilliant pictures, but they show some interesting detail. The first three are bacteria and air bubbles taken for no reason at all.
