Hello. I have recently acquired an Olympus 35RC and am really enjoying this little camera. I bought a 43.5mm Bower 1A skylight filter and an old stock Vivitar yellow B&W contrast 43.5mm filter. I would also like to get an 81A warming filter, but the only 43.5mm 81A filters I have found are from SRB-Griturn in the UK (http://www.srb-griturn.com/
). I am a bit leery about these as the website states that they are made from optical resin, which I interpret to mean plastic. I have only used multi-coated glass filters. Does anyone have any experience with the optical resin filters from SRB-Griturn? My alternative would be a 43.5mm --> 46mm step-up ring and a Hoya or B&W multi-coated glass filter. I would rather have a 43.5mm filter to keep the compact 35RC as trim as possible.
Thanks in advance for any help you can provide.
