oh so u saw me on the bridge? where were u all?
are u sure ur shots are out of focus? i'm talking about the
fireworks. becos the aperture setting of the camera determines how
"fuzzy" the fireworks look.
also, at ur huge 12x zoom, the camera may have problems focusing
(for non-fireworks shots) and also camera shake becomes very
evident at that focal length (~420mm rite?)
a UV filter absorbs uv light that can cause a haze to your photos.
but i can't imagine it absorbing all the uv light when u are doing
ur uv experiement! eheh it'll be interesting to see the difference
tho.. if u are bothered, post it up and see if there's a diff?
