I much prefer to keep a skylight or UV filter over my lenses to provide some mechanical protection to the front element (I have heard the arguments for not doing so and remain quite unimpressed). The Canon 50mm f1.8 lenses present a bit of a challenge as the 40mm filters (not 40.5mm) which they require are difficult to find.
I just bought a couple of 40mm UVscrew in filters on eBay from a fellow in Hong Kong who does business on eBay as "buybuyeasy". The two I needed came to about US$15 total with shipping.
The filters arrived today and I'm pleased with them. They're brand new glass filters in aluminum mounts; these screwed right onto my chrome f1.8 Serenars without problems. The manufacturer was Marumi in Japan, a maker I'm not familiar with but as the packaging was labelled in English and French as well as Japanese, Marumi evidently sells outside the Far East.
Those interested in 40mm filters might check this seller on eBayor contact him directly to see if any more of these are available
