help making sigma 8mm work on d50 nikonWell I have a second hand sigma 8mm D f4 ex (bare lens no box or manual) and a nikon d50.
I'm now feeling a bit more humble than usual as it looks like I may have to pay a bit more attention to it to get working.
I managed to get the lens mounted by lining the long line on the lens barrel up with the dot on the camera and turning anti-clockwise.
But now all I get is a message F EE in the control panel and in the viewfinder if I press the shutter. Reading about this suggests it cannot read the aperture and on some lenses you need to lock the aperture ring or something? I can't see any obvious switches on the lens. One small tab like thing but that seems fairly solid and I don't wan't to damage it forcing things.
I have tried puting the apeture ring on f4 the lowest before mounting and turning the nikons dial to M for manual and manual focus but it does not help. I can see through the lens via the viewfinder just fine. But can't take a picture.
If anyone can help me get going I'd be much appreciated. Hopefully I'm missing something obvious. Oh and if anyone has the same lens and could pass on a scan on any instructions which come with it that might be handy?
Thanks very much. Going to walk the dog now and come back to it with a bit less frustration.
