hello all. I am an amateur shooter who rented this lense knowing the streets and forts/castles of sanjuan were going to need a big lense. these pictures are largely unedited. minor crops here and there and upon further inspection it would seem I had some dust on my lense or sensor. being that it was 90 and humid all my gear fogged up as soon as I left a/c so I admitted I pushed some air thru the body and lense in an attempt to speed things up! c&c always welcome. this is my first time with this lense and ive only been shooting less than a year.
