This is not a bad price for what it's been selling at lately, but $70 is what you could have gotten this for about 1 year ago.

90 buckz plus tax, that kills the deal. i got mine like 2 yrs ago for 80 buckz free of tax. this is one of the must own lens from Canon. cheap but SHARP!

This become 80mm with Canon's x1.6 conversion factor for APS sized sensor. I wonder whether the prespective is the same as 50mm or not.

#4 the lens doesn't "become" 80mm. The lens has a physical focal length of 50mm, and there is nothing that you can do to change that! An APS-C sensor camera will have a a narrower FOV, compared to a 35mm sensor camera, but the focal length of any lens does not ever change.

Gotta love the "Last year it cost..." and "Two years ago I only paid..." comments. That was then. This is now.

great optics for the price, build is fragile, so be careful with it. #5 is correct, a 50 is a 50 no matter the body. 1.6 croppers will only get the sweet center area relative to a full frame. still a fine little lens. you'll pay near $350 for canon's 50/1.4, better build, but the cheap nifty-fifty (aka plastic-fantastic) still holds its own. IMO this lens is far, far better than the kit 18-55. but be warned: it's a gateway drug. you'll end up pennyless with a ton of great images.

wow, i didn't realize this lense was that cheap at one point. I waited for about a year for a significant price drop on this thing ...but ultimately opted for the f/1.4 version instead (need the durability). The 1.2 is awesome, but probably not worth the extra $1k for most.

I think I got it for around $70.

#5, I was comparing the lens perspective of APS sensor or 35mm sensor. When it said 50mm physical, then it is 50mm for 35mm sensor.

But if it is used in a cheap DSLR with APS sized sensor like T1i etc, it has a conversion factor of 1.6x (others brands are most 1.5x).

When this lens is used in a DSLR with 35mm sensor, it is 50mm. For a Canon APS sensor, it is 80mm (Perspective-wise).
