best canon lens wide angle image
cross045
I have a Canon Rebel XT camera and i wanted to get a wide angle lens, i was just wondering what is the difference between the converter and the full wide-angle lens? Ive seen the wide-angle lenses but it seems like there so exspensive... Is there a difference in quality on a converter? And is it better to get a converter lens or the actual full lens? Maybe some good sites to buy these lenses??
Answer
A wide angle lens replaces (temporarily) your standard lens, while a wide angle lens converter screws onto the front of your existing lens (it requires that you get the right one based on the filter thread at the front of your lens).
If it were that simple we'd all be using wide angle converters and there would be no market for wide angle lenses, however there is, so why? Well, the reason is very simple, every wide angle converter I've seen causes horrendous chromatic aberration. That's to say that the colours of light are not focused properly and so especially at the extremes of the image and at edges within the photo you can see the colours separating. You can use this to artistic effect, but with little control, it's more often just plain annoying and makes your photos valueless!
Even the best wide angle lens is going to display some chromatic aberration, but far far far less than a wide angle converter will.

Any way to add more of a fish eye/distorted look to wide angle lens?

I bought a Canon 35mm wide angle lens. I took a couple shots, and the pictures look like they were taken with a regular lens. I was expecting more of a fish eye/warped perspective look. Is there an accessory I can put on top of the lens to add to the wide angle look?
I have a Canon EOS Rebel XS.
Answer
It depends what type of camera you have. If it has an APS-C sized sensor, a 35mm won't be wide angle - it'll be closer to a normal lens. On an APS-C sized sensor, a fish-eye might be 10mm or less.
EDIT > yes, your rebel XS has an APS-C sized sensor.
