I posted an article about circular polarizing filters recently, letting you see some data I obtained for Lensrentals when they were reviewing which of the polarizing filters were among the best. I concluded that they all polarized light really well. I also said that none of the CPs I tested seemed to cause optical problems at […]

In terms of image quality, raw offers unparalleled advantages because you are capturing sensor data rather than the video stream it produces, however, turnaround time or budget […]
