Having seen many of your close up fish leaping, thrashing shots, do you get many instances of water splashing onto the lens? I find this to be a problem that is usually only obvious after it has ruined some otherwise nice shots ...

Hi Mark,
I think it is the scales thing as you say - they are a b
ugger for blowing out highlights - and the polariser was cutting through the water surface and making such nice dark backgrounds in these shots, so it tricked the camera (in shutter priority) to open up too much. So, it was a bit of everything - too much reflection, too much exposure, too wide a dynamic range. Something had to give.
When the polariser isn't on, most of the time I find I don't need -EV dialled in, as the reflectiveness of the water balances that of the fish. I don't use a polariser often (hence me being a bit naive on the shots in question), as it is too much to be able to give up 2 stops of light this far north and still be able to use 1/1250 sec.
I tend to use evaluative metering, as the target is jumping about too much to rely on spot or partial metering to be on the subject when the shutter is pressed.
I wouldn't say water splashes from fish are any bigger a source of lens splodges than a dozen and one other things when using the camera out in a boat. It certainly pays to check for splodges regularly and keep a cloth handy. Strangely enough, I have a much harder time trying to keep the lens clean on my compact, which I only use for the odd river and hill loch shot
