Marumi CPZ Filter,
Verified Purchase(What is this?)
This review is from: Marumi DHG Super circular polarising 62mm Filter (Accessory)
Did a lot of Googling before picking this particular filter and the review of Circular Polariser filters by lenstip.com highlighted the Marumi. Used on my Sony a55 with 18-250mm travel zoom, the results are excellent. Many more keepers than before. The only downside is the inevitable loss of light, maybe 1-2 stops, however the ability to clean up most bright daylight scenes to get the contrast and saturation you're after ( not just landscapes ) is more than worth it. My UV protection filter has been replaced by the Marumi as the "always on" filter.
