I have just purchased a Sigma 12-24 2nd hand. There is a front 'clip on' cap (not the petal hood) but no way of fitting this cap to the lense or petal hood.
In my research I see references to a separate connector that appears to fit into the petal lens hood so the cap will clip on.

Similarly I see references to a rear holder for gelatine filters but there is no holder with this lens and I cannot see anywhere to fit one.

Is there anyone who owns this ens that could advise please.

Thanks
Dave
