i have a 28-80 lens for my 20D. i read that the ratio is 1.6 so its really acting like a 44.8mm lens?

I want a super wide angle, even fish eye for my 20D. Limited budget as always. Any suggestions? I was even looking at the fake fish eyes on ebay for like $50 that thread on to an existing lens to get the effect. I would really prefer just a super wide lens.

also, anyone know of any sites with examples like a picture of the same content, just using different lenses so you can compare and understand the looks of them more?

thanks
tim

The 1.6 is the field of view multiplier. Basically, a 50mm lens on your camera will show you a field of view of an 80mm lens. So your 28 to 80mm will appear like a 49 to 128mm lens.

Hope this helps...

Tim,

Here is the magic formula, follow my instructions to the letter and you will be shooting Vogue covers in no time...

Stand in the corner of your room

hold your breath

close your eyes and repeat the following MAGIC mantra:

'don't buy cheap glass...don't buy cheap glass...NEVER buy cheap glass...don't buy cheap glass...

seriously, dude, any nickel you spend on a cheap lens --wide angle, telephoto, doesn't matter-- is one that should have been stuck in the cookie jar and saved for good stuff. I speak from personal experience.

Also, if you're buying work tools, buy the one that will help your work the most. If you have some special need for a fisheye, great, if you just think it'll be cool, you should really look at how much use you will actually get from it.

It's your work, it's your art, it's your life...don't buy cheap glass.

Good luck with your choice,

Shannon

At its widest setting your lens is acting like a "35mm equivalent" of a 45mm-ish lens (the ratio's not perfect.) That means it has the same field of view as a lens on a 35mm film camera set to 45mm focal length. At its maximum zoom it's got the same field of view as a lens on a 35mm camera set to 130mm or thereabouts (you can usually round to the nearest few mm and still be close enough to get the picture.)

That's a rough trick with a non-full-frame DSLR, as the thing always costs you field of view. (Keep in mind it's not just short focal length that makes a lens a fisheye lens.) Here's Canon's wide-angle lens lineup:

http://consumer.usa.canon.com/ir/con...categoryid=151

They go clear down to 14mm on a non-fisheye lens. That is a 23mm equivalent, which is fairly wide, on your camera. However, those lenses are in the four digit range. You can get a 24mm (38mm equivalent) for around $300.

Sigma's aren't bad, I picked up a used 14 for 400. That works out to a 22.4 mm on my Canon. It's pretty sharp as you're not using the entire field of view.

I have a Canon 14mm and on a 1D MK II is distorts Models too much to use. Yeah it will be ".3" larger on a 20D, but I doubt that will change the outcome much.

If ya want wide, get the Canon 17-40L, that will cover plenty of your needs.



This was with the 14mm

if you're looking for the fish-eye distortion effect (despite the 1.6 crop factor) its still gonna give ya the distortion, albeit not as much of it. if you're looking for ultra-wide, the 1.6 crop is gonna inhibit you.
