Originally posted by JimJohnson So fool the camera into thinking all lenses are 'A' type. There are several threads on this topic. P-TTL flash will then work with a manual lens. You just need to set the same aperture on both the camera body and the lens.
NO!!!
For this to work, you'll have to:
- short the A pin (using some soldering, or aluminum foil).
- disable the aperture link between the lens and the camera (best method is by mounting your lens only halfway).
- select the widest available aperture
on the camera, no matter what aperture you actually use on the lens.
(Downside of this method is that your viewfinder will darken considerably with smaller apertures)
Non-A lenses cannot be easily transformed into an A lens due to the different aperture link behavior.
Though, with some luck, some third-party lenses can be transformed, as their aperture couplers are behaving just as with an A-lens. The Porst 55/1.2 is such a lens, without an "official" A position but perfectly compliant with the surface-related aperture behavior.
A better way would be to invest in an Auto flash...
