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.

Yeah, you need to compensate for changing the amount of light hitting the sensor. If you goto a darker scene it is going to be darker picture so you need to bump up ISO or Aperture or slow the shutter down till the meter is centered.

I think you need to read up on exposure to understand what is going one when you move that camera around. Try the resources in the stickies on this forum

There are small devices that slide into your camera's hotshoe and provide a pc-sync connection like these: http://flashzebra.com …oes/camera-hotshoes.shtml (external link)

Thanks for replies.
I sensed that I would have to change shutter speed or bump up ISO.

Regarding synch cable or wireless. I know what they are. I wanted to know whether the exposure would be correct with shutter speed at 1/125 and set at AV or M, or would I have to look at what I had taken and adjust ISO or Shutter speed?
Thanks again for your time and patience.
