The free gift diffuser which came with the Vivitar 285HV was a pain in the arse to setup so I was looking at some diffusers to buy online but they were all about $30 and didn't want to piss the wife off too much as I think my little photography related spending spree is officially over!
So while stalking another local camera shop in Fukuyama I found a pretty cool diffuser that comes in M and L sizes which basically just sits over the flash head quite snuggly and happens to look just like a chef's hat! Surprisingly, this product is made by Kenko and re-branded as Harbor and costs ¥840 ($7.60 USD) for the L size and a few dollars less for the M, very cheap.
Here are some examples of Batman posing just for me.
