Sigma 105 Not Registering Aperture
as I was taking it off it flashed up the F number, about half way round when twisting it off.
Did you have the camera switched on while removing the lens? I only ask because I was told the sensor acts like a vacuum cleaner sucking in dust if doing that. Could some of the contacts have shorted out ?
Finally got my hands on the correct screwdriver, just took out the screws in the mount, gave the mount a jiggle, re=seated it and tightened the screws back up and it worked a treat!!!
Just an update....

Typical Sigma issue - there are a couple of threads somewhere about this. I have the same problem with the 170-500, I just keep a small screwdriver in the kitbag in case I problems whilst out and about.

Been in work most of the day, building a display for our stand in the upcoming Show we're attending. On the way home I put on my sigma 105 and it's not showing the aperture, as I was taking it off it flashed up the F number, about half way round when twisting it off.
I've thoroughly cleaned the contacts on both sides.
The mount on the 105/camera is not loose.
Every other lens I've tried is spot on.
When I find my screwdriver I'm gunna loosen the mount on the lens and re-seat it if you will, give a jiggle! I'm not gunna take the mount off, just loosen it.
Any ideas folks?
