I know UV and CPL are different applications, UV can block out unwanted sun rays whereas CPL can take pictures to see through water or glass windows.
1)Generally, people will buy UV or CPL?
2)Does CPL has the functions to block out unwanted sun rays too?
3)Which brand is better, I know hoya is good, but will Tokina and Kenko serves the same purpose at almost half the price? Please convince me if you think i should get Hoya instead of tokiina or Kenko.
Many thanks in advance.
