Are you saying AF confirm doesn't operate when chip is set to f/8?

All three report the EXIF data as programmed and all three work with both my SL1/100D and 5D Mk III. What I have noticed is the Big_Is and Adplo will allow me to change the aperture on the camera and it will show up on the LCD screen and also in the EXIF dada.
The Tagotech is always stuck at f/2.8 on both the camera and the EXIF data. (unless I enter the program mode)
Is that normal behavior for these various chips? Is there a way to program the Tagotech so that I can change the reported aperture simply by spinning a dial on the camera as with the other two? |
Did you check the documentation at Tagotech web site?
