I am looking at getting some Lee gnd filters to use on my 10-22mm. I just have a couple questions. Will the Lee 4 filter holder vignette on the 10mm end? Would you folks even recommend using a filter holder or would you just hand hold the filters? Last question... would you recommend the Lee filters or the cheaper Hi-Tech filters?
Shouldn't be a problem as long as you use the wide angle adapter (10mm is 16 mm equivalent and it's fine with my 16-35 on FF). The adapters come with hardware for 4 slots, but only have 2 installed initially.
Lees are very good, and the hi-tech seem to have a good reputation as well, just stay clear of the Cokin ND Grads as they have a reputation for colour shift
