For a dSLR, there's no difference between UV and Clear. I'd get whichever is cheaper.
Thanks for the reply ... I am aware that they do not make any difference, what I wanted to know was their thickness as you had earlier said 3.4mm ... so I wanted to know which one you got that is 3.4mm thick (as B&H does not seem to specify the thickness. Also, there is just a $10 difference between the two. But having read your earlier post again I noticed you had clearly mentioned "UV"
Thanks for your helpful advice ... much appreciated.
