Last sunday, i went to indoor stadium alone for taking photos. I make friend with one of the photography club member mr.huang. He was using Sony Alpha A350 with 18-250 travel lens...haha i was sitting the floor there for 5 hours for taking photos...i just realize so long didnt touch my camera, and i felt how heavy is my KM 70-210mm, and the next day my back is pain cos sitting there for too long...below is some of the photos i took on that day,comment and critic are welcome and some of the photos is in flickr. Thank for viewing~
