T switch on Leicina camera
I have been using a Leicina super RT1 for some time now, but do not really understand the "T" switch function. I know from the manual that opens the shutter when you first pull it, and closes on the second pull of the trigger. For what kind of shots would I use this? Does anyone have this camera, and use this function, which I think is also found on some Nizo cameras.

Most probably this is for Time Exposure. You keep the shutter open for as long as you like. Equivalent to B mode on 35mm still cameras. Good for composing still frames under very low light conditions or composing frames with flash and many other things.charlieboy wrote:I have been using a Leicina super RT1 for some time now, but do not really understand the "T" switch function.

According to the Leicina Special instruction book the 'T' function is used as follows.
"For long time exposures of single frames the letter T on the rotating knob (21) is lined up with the red dot. The exposure must be determined with a separate exposure meter, allowing an extra one half stop"
What it means is that you only use the 'T' setting for single frame exposures where there are very low levels of light or when using the minimum aperture of the lens with low lighting. Could be used for animation when great depth of field is required.
Using the separate exposure meter set the film speed on the meter to the same as the film in the camera. Take a meter reading and then add 50% to the time i.e. if the meter says 10sec then actually expose for 15sec.
Hope this helps.

I never read that bit about increasing the exposure 1/2 stop. Whats that for? Maybe to allow time for the shutter to open and close on shorter exposures, and reciprocity at longer?
You can use the T setting with the ST1 controller to do long exposure timelapse too- some nice rivers of car lights at night etc.
