are they really needed? if so whats the best to fit? or whats the uses for different ones? i think the sony lenses i have are 55mm, and mostly used for motorsports(MX,etc.)?
thanks
Paul
For MX use the only real benefit would be as Stan stated, a protector.
For lanscape it's extremely beneficial. You can use graduated filters that you place so as to filter only the sky where it is brighter than the land. Or you can use ND filters to hold back light and get longer exposures where clouds or water moves making them appear almost silky.
Oh and it's fun![]()
I had stones bouncing off the front end (fortunately just the el-cheapo hood that I fitted) of £1200 worth of 70-200 VR today - a filter and hood are essential for any off-road motorsports if you plan to get close to the action...
