I have an Ashai super Takumar f1.4 50mm lens.
I am using on Camera 500D.
I use M or Av settings.
I have noticed that as I point the lens in different directions the exposure compensation indicator changes. Sometimes into the - side [too dark].
How can I get the indicator into the centre? I use ISO dial at present.
Any other ways of ensuring correct exposure please?
I forgot ! Want to use with synch cord to studio flash. Any suggestions?
Want to set at 1/125 if possible.
