Hi! New here with a question, I have searched all over the internet and have done quite a bit of reasearch but am still over my head. I need a fisheye lens to take pictures of skateboarding (vert ramps if you care) and need the lens to be cheap, around $100, and need it to be able to get all the surroundings of the skateboarder. I am using a Canon powershot S3 and would prefer matching gear but doesn't really matter as I am so new to this. I will get old eventually and would like to have some photos to look back on, and say wow I went there and did that! I also want to grow as a photographer and learn quite a bit before sinking money into gear. I trust you guys more than me! Thank you for your time and patience.
