CLS filter
Yesterday I was recommended and purchased the Astronomik CLS - CCD filter for the Canon 60Da.
I knew the CLS was for unmodified and the CLS - CCD was for modified but as I have the 60Da and wasn't to sure, I asked the shop attendant and he recommend the CCD
After reading a post today I see that the CLS would have been fine.
My question is, other than the $40 is there any other advantage in driving back and exchanging to the CLS filter?
