Good fisheye lens? What size are the front threads on a Canon Digital Rebel Xti? ?

Question

I am gonna buy a fisheye lens for it off eBay. any recommendations for a good lens that will fit?

Answer 1

You want an addon fisheye lens you can attach to your Canon lens?

The lens you buy will be a cheapy, so don't expect much at the edges of the image.  I will produce soft edges and a lot of colour adoration at the edges too.

Have you found one?  The rear thread on that lens will tell you which lens adapter ring you will need to buy if the supplied  one does not fit your cameras lens.

And you see, you will not have to spend any money on eBay and it is under $70.   By the way, it will not be a good fisheye.  Good fisheye's cost over $650 and there are none yet made for your camera.

Answer 2

I've ben eyeing a couple fisheyes as well. They're not cheap, but worth the fun.

Here's what I've been looking at for an XSi, all get fairly good reviews from users but you might want to google for more pro reviews:

There's also a Peleng 8mm. It's cheap but as far as I know you need an adapter for EF mounts. That's a turn off for me.

p.s. I'd be very careful when buying anything on ebay, especially when it comes to cameras and camera equipment.

I personally have not dealt with them for bigger ticket items, but know a few people who bought electronics and lenses,  I've yet to hear a good thing about ebay. You're probably much better off spending a bit more atAmazon, Adorama, B&H etc

Just some food for thought....

Answer 3

If you can shell out about $560, you can get the Tokina 10-17mm f/3.5-4.5 fisheye zoom.

However, if you want cheaper and are willing to manual focus and use stop-down metering, you could perhaps look at buying the Zenitar 16mm f/2.8. It is an M42 lens though, so you need a M42-EOS adapter to fit it onto the XTi. (Some copies of the lens are already fitted with an adapter, so read the advertisements carefully). Also, 16mm doesn't produce much of a pronounced fisheye effect on an 1.6x crop sensor such as the XTi.
