After buying this lens, I started manually focusing for 2 reasons - AF is confused while shooting birds, 2 - it makes loud noise. Although I feel this lens may not have that high resolution to shoot small objects like small birds and tiny flowers, I wanted to check how far I can go.
I shot many of these pics in raw and PPed in Lightroom 3 (recently started). I still have to find out why the photos are getting fuzzier after I upload them into forum albums. May be I am missing the right size and quality for web publishing???

A very nice series. You must be pleased with this lens.
