who uses a Canon type II tele plus the 52WII polarizer plug in filter?
Hi guys, I'd be very interested in sample images and your thoughts on using the 52WII circular polarizer on the 300 / 400 f/2.8 II or the 500 / 600 f/2.0 II (thoughts on the type (I) teles are also welcome. I own the 300 f/2.8 L IS USM II and think of spending the 200 bucks for the filter (sorry only the above mentioned lenses are of interest to me) I have following questions: 1) How much is the image quality affected? 2.) How much light do you loose - is it in the range of 1-2 stops? 3.) Do you use it often or is it a waste of money? 4.) In which situations do you use the polarizer? 5.) Is the lens still water resistant with the filter in place? 6.) How good does the mechanism to control the effect work in the field? thx for your answers in advance!!!
i do have the filter you mentioned for my 300 2.8II but i haven't used it yet, this may not be the answer you are looking for but i'll be interested in other photogs answer who have used it, as well ;-) i will let you know when i use mine but i am not sure when at this time! :-( cheerz.
