Hi guys,



please could somebody tell me, how would the Samyang lenses (which have no eletrical contacts at all) work together with flashes?



I mean lets say I will use Nikon D700 with Samyang 85/1.4, SB900 on Nikon as master flash and one SB600 from the side of an object as a slave.... Will I get correct exposure at all?



Or just D700+Samyang+SB900 only - will I get correct exposure when changing the distance, changing aperture from 1.4 to f4 (for instance)...?

You can go for the dedicated Nikon version with coupled aperture.

You may not be able to use 3D Flash but generally the exposure should be fine here.

PS: No idea about the slave flash dependencies in Nikon land.

You should be able to get good TTL flash, exposed for your subject regardless.

Well, just as well as with pre-D lenses.



However, in practice it seems to really go off the rails from time to time with old, manual lenses. I've had exposure vary by as much as half a stop with old (AI) lenses. Only when stopping down though.

Never figured out the exact why. Then again, I use flash very rarely so I didn't care enough to find out.
