Hi Collin & David, we normally do not use color filters when shooting B&W on a DSLR. Reason: todays DSLRs have built in color filters, which you can use very easily, rather than attaching a filter physically. So also photo programs like Photoshop have a variety and strengths of color filters. But hey, why not have some fun with actual color filters if you have them?? I use Circular Polarizers, Neutral Density & Graduated Neutral Density Filters with my lenses. And a GND on my Sigma 10-20 SWA is an absolute must as it covers a huge swath of sky. But using a Polarizer on this lens can be tricky due to great variation in the sky darkening effect - not uniformly darkened. Since I am not a Pro, I have decent mid-cost Circular Polarizers - $ 29 to 50, a Hoya Pro1 ND - $ 62 and Cheap Chinese ND & GND Filters - $ 4 to 9. And you bet the cheaper Chinese one are as good as any. I buy the largest diameter filters and plenty of step down adapter rings to economize and use them on all my lenses. Regards. Bipin - from that far away enchanting land.
