does anyone else with a Fuji S5200 have problems with the AF with a Polarizer... seems like when its on Auto mode, the camera isn't getting the settings right, end up with ALOT of noise

the (circular) polarizer will decrease the light gathering ability of the lens by up to 2 full f stops (4 times LESS light)



this will result in the camera (when in auto mode) raising the iso resulting in additional noise



try it in 'P' modeand use a tripod if the shutter speed goes too low

hmm.. okay thanks . I'll try running it in P mode. Say if I manually adjust the iso, can I still keep it in Auto mode?.. will the camera detect anything else differently with a polarizer?

Andy,

There is one way for you to REALLY know the answer to that question. Try it and evaluate the results. You have the camera, you can make the adjustments, and if it works you have found a solution for you. If it doesn't, you can try something else. I took my S5100 to Alaska last summer and got some very sharp pictures of Mount McKinley during a flyover, using a polarizer. And if I recall correctly, I left the camera set in auto mode with the ISO set on 100. Just keep experimenting until you find a combination that works for you.

I use an old Optex polarizer (linear) on my S5200 with no problems. Polarizers reduce the amount of light reaching the sensor by about 2 f-stops in most cases, so if light levels are low, taking the polarizer off can make a big difference.

the high iso is the CAUSE OF THE NOISE

these P&S cams have very small NOISE PRONE sensors

as soon as the iso goes up - so does the noise

you must use a tripod with a low shutter speed to maintain a low iso/low noise shot



sorry, this is a photo fact
