This may be a simple question...but it has perplexed me for a fair while. When in picture mode shooting in manual exposure with the frame rate set to continuous - High, why do i notice a change in the frequency of shutter actuations when i point the camera at different areas of brightness? I would have thought that the manual exposure settings would overide any delay in the continuous shooting mode. (all settings are conducive to achieving 8.5 fps) any help on this would be helpful, as i cant work it out. thank you. Oh and this is the same with various lens types, sigma canon tamron and all in MF mode.
Any ideas please et me know. Thanks
