I don't use a filter unless I'll be shooting in unusually dusty, nasty or windy conditions. That's not really to protect the lens. I find it's easier to clean the filter than to get dust out of the crevices of a deep-set front element.
I know I've probably told this story before. Back when public smoking was more common the camera reps would demonstrate the robustness of lens coatings by snuffing out a cigarette on the front element. gs George Sinos -------------------- gsi...@gmail.com www.georgesphotos.net plus.georgesinos.com On Tue, Sep 18, 2012 at 9:54 AM, Doug Brewer <d...@alphoto.com> wrote: > On 9/18/12 12:45 AM, Bipin Gupta wrote: >> >> Yes this is an oft repeated old stuff.
