I wanted a longer lens than 200 mm so looking at prices of lens for my Nikon D90 for same brand saw me not able to afford one till much later than I wanted to wait, so conundrum, what is a good lens that does not cost the earth but gives good results, well, found out the Sigma 70-300 APO DG lens to be better in specs and clarity than I first gave credit for. Am I happy with the results, my word I am, it's been a great lens for quality photos and is just the length of lens I needed.

Now I'm looking at another Sigma lens for close up photography, well more affordable than Nikon lenses but no way is it worse in quality photographs, that is the bonus.

Cheers
Stuart
