So I went to Lakeland, FL for Sun N Fun, a fly-in down there. Here's just a few of them. The re-named ones have been re-worked to look a little better. All were shot with either my 18-135 kit lens or my sigma apo70-300 lens. Thoughts on the 18-135 are it does good for the up close stuff, but it's way too short for anything in the air. It did well at the beach and overall as a walk around lens and i'm pretty satisfied overall, but it seems like my pictures aren't as sharp as what i see on here, is that because i view them in microsoft picture/fax viewer at "show full size"? or is it that these lenses aren't that sharp? As for the Sigma It seemed like it took good pictures in general and was sharper than the kit lens, at the kit lens ranges, but got pretty soft pretty quick once it got past the 200mm mark. Is that pretty standard on <$500 zoom lenses? On a few of them it looks like i may have a bit of dust on my sensor. What would be the best way to clean or check for this? I changed between the two lenses about 7 times total on the whole trip. One thing i noticed is that sometimes if the lens got rotated a little after it was locked in, is that it wouldn't register the F stop setting and would pull up the "- -" indicator. I could fiddle with it, and it'd come back to whatever the current setting was, but is it something like dirty contacts that makes this happen? i wouldn't expect this out of a $1200 camera system, and would assume that it'd be perfect lockup every time. Is it something i'm doing wrong? Also, I've probably got 2000+ shutter operations on my Nikon D80 after just getting it a week ago. Is this bad? as in, do they have a limited life? Should i slow down? Anyway, i'll post some better, re-worked pics later.
