My Girlfriend bought me a pancake hood from Wendy's.I believe I need to buy a lens for it ( hasn't arrived) . Was looking at the ebay AD lens but wanted to know if anyone has any experience with them Good/bad.http://www.ebay.com/itm/New-4-1-4-x-...#ht_2445wt_956I already Own a Metal Man 4"x4" and have used the Miller 2"-4.25" in class. But aftergetting sparks in my left ear (pipe) I wanted to try a Pancake. Was even thinkinga fixed gold lens if the ebay AD ones are crap.Thanks.
