I'm interested to know if there are any limitations when shooting with a manual aperture lens in aperture priority mode, compared to shooting with a fully automatic lens.
In case this isn't clear, the lens has a ring that sets the aperture. There is no wiring to communicate aperture information to the camera, so the camera does not know what the aperture is.
Questions I have when using aperture priority mode:
- Is the camera able to calculate the exposure with this lens?
- Does TTL flash metering work?
- Can I bracket the exposure?
Edit: while I'm interested in general about how cameras support this configuration, I need to have this information for Canon DSLRs, specifically the 60D.
