My local camera shop had the 77mm Cokin P filter holder + lens adapter for $19 so I decided to go for it. Now I just need to buy a filter or two and start taking photos! 17mm on a crop sensor will still likely not vignette or barely do so. If I go full frame later I'll re-evaluate and likely get the wide angle adapter.

I really like the idea of Lee, but don't have the wallet for it

Thanks
Dave
