Whats a good Fisheye lens for a canon rebel xt?

Canon rebel xti fisheye lens?

• I have a rebel xti and I want to get a fish eye lens for it. I have seen photos of people using fisheye lens and it has ugly black triangles on the four corners, like it didnt get the entire fisheye effect, i want to avoid a crappy lens like that. i want to get one that is going to give me an all around fisheye photo with no black triangles on the corners. I dont really know what to look for, so if someone could link me to a good one or tell me what one is good i would love you forever!

• Answer:

  The vignetting that you describe is usually an effect of a wide conversion lens. You have two of choices: Canon EF 15mm f/2.8 Fisheye: Samples -- http://www.flickr.com/search/?q=ef+15mm&ss=2&ct=5&s=int Product page -- http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=151&modelid=7321 Sigma 10mm F2.8 EX DC HSM Fisheye: Samples -- http://masterchong.com/v2/lens-related/sigma-10mm-f2.8-ex-dc-hsm-fisheye-review-and-sample-p.html Product page -- http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3337&navigator=6 The Canon will rob you of about $660 while the Sigma will ask for about $600. Follow-up: Oops, David M is right. The 15mm EF Fisheye won't present the same effect on a crop sensor. Scratch that off the list and add the Tokina AF 10-17mm f/3.5-4.5 DX Fisheye. Samples -- http://www.flickr.com/search/?q=tokina+10-17mm+xti&ss=2&ct=5&s=int Product page -- http://www.tokinalens.com/products/tokina/atx107afdx-a.html The Sigma 10mm is still a good choice. I doubt you'll like the Sigma 4.5mm. It's a circular fisheye which means you'll get the entire image circle. The image will be encircled by complete darkness. Here's a sample from a 40D (same crop factor as the XTi): http://www.flickr.com/photos/u07ch/2533867937/
