Thanks Marcel :) I really don't know much about the lenses as i used to take pictures with point and shoot cameras. I use nikkor 18-105 mm lens and I think I still need to practice a lot. Here's a photo I took of a baboon, but it's not good as the image of the monkey is not sharp.
I am trying to upload some photos, but I keep getting a message that says "you need to correct the individual information." I filled all the required fields. Is there's a problem with the site today?
