Get a Skylight UV filter
I already posted this in another Forum - but thought I should share this here too: -
OK - here's a seasoned photographer who's casually dabbled for more years than he'd like to admit to.
However - no one is immune to overlooking basics sometimes!.
After I got my initial dSLR settup just over a year ago - I found a minute mark on my Sigma 17 - 70
Horrified I remembered I hadn't purchased a protective UV filter.
Fortunately there is no visible effect and the mark is tiny.
So both the 17 - 70 & the 70 - 300 were duly fitted with UV filters.
I always used UV filters or skylight filters on my lenses in my fSLR days - so why did I forget?...
Now - I just purchased an inbetween lens which could turn out to be used more than I thought it would be
the 28 - 200, which I found has been discontinued - I got the Sigma so at least I have a matching set (not that it really matters).
Taking some comparison shots at the same focal lenths I noticed outside that the 28 - 200 had a slightly, almost soft, haze to the fine detail - I figured it was just not quite as sharp as the 17 - 70 (which it probably isn't). Then it dawned on my tiny old brain cell - I haven't got a UV filter on it!!!!
How stupid can I be and still be alive??
Buy a filter to protect your lens - make it a good one - not a cheapo one - they are more likely to cause reflections off the digital sensor. I am very pleased with the Sigma DG one I got (to match the lens) other makes, like Hoya, for example are good too.
BTW - shop around - prices for the same thing vary quite a lot!!
