Just curious if anyone has come across a site which features before and after polarizing shots using the A40?

Really interested in getting a polarizing filter cos i'm living in the Tropics where glare is often a big problem. I'm rather new to this and don't wish to spend a bomb on the filter... Any good recommendations?

I just bought an adapter for my A40 and then priced out a polorizing filter. I was surprised to find out that digital camera's cannot use regular linear filters that are used on manual film camera's which are about $25.00-$30.00 cdn. Something to do with the way the polorizing was applied to the actual glass. The polorizing filter for a digi was $63.00 cdn. It actually made me rethink sinking money into my 2 megapixel camera. I decided to wait until I can afford a 4 megapixel such as the G3 or G2.

I had an A40 (upgraded to G3 now :-) ) for which i bought the adapter and a circular polarizing filter, which as far as i am aware is a standard SLR filter. It worked fine for me, I did various test shots to get some idea as to how the circular polarizer worked as i had not used one before, and it reduced glare as expected.

IMHO the A40 is well worth investing in some accessories for as it takes great pictures.

I've read quite a few articles on linear vs. circular polarizing filters.
Apparently you can use EITHER on digicams.

Linear filters are just not to be used with some point and shoot film cameras because these cameras
use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance.

Digicams dont use this method, so either type of filter is ok.

In case you are not sure, check google. You will find this is always the case.

Thank you for your findings. This is good to know.
