I bought a set from ebay. It came with hood and a snap on cap. The cap is a 34mm snap on cap.
Here is a link I found: http://www.ebay.ca/itm/JJC-LENS-HOO...ultDomain_0&hash=item3ccfcf7141#ht_3546wt_816
Does the hood really do anything for the 10mm? It just seems so tiny so as to not really do anything.
Thanks. I'm going to get one. I am hoping it makes me like it more. I've been thinking that it should have more contrast than I've seen.
