As others have commented and I was beginning to suspect there seem plenty of working lenses that appear on the compatibility warning list. So far there is not record of any damage to cameras... only that some lenses don't work fully.
As the Sigma upgrade is not free for older Sigma lenses bough secondhand in the UK that is helpful when considering second hand purchases. Sigma UK state the following:
If the lens is under a year old there will be no charge if the lens is older please see the following:
1: £5.00 per lens if you have proof of purchase for the lens from new which is to cover return p&p.
2: £37.99 per lens if you have no proof of purchase which is to cover the cost of Admin and postage.
Thanks everyone and I hope this has been helpful...no guarantees of course, but there is certainly a chance that many lenses may operate fine...but HSM versions may be more of an issue, but probably mostly fairly recent and hence mostly bought new.
Cheers,
Paul
