I've got a Sigma f/2.8 30mm DN lens and a Panasonic Lumix 45-150mm f/4.0-5.6 lens that I want to put UV filters on. I need the 46mm for the Sigma, and the 52 mm for the Lumix. I'm planning on using the Hoya Pro1 Digital Uv filter. Is there anything I should be aware of because these are micro 4/3 lens? Or will these filters fit perfectly? Kevin.
