    I'm enjoying my new Rebel immensely. I'm looking into getting a nice portrait lens to take family pictures and I was curious if anyone could give me some advice regarding the cannon 85mm f/1.8 or 100mm f/2...

    Does anyone have either of these lens or can give me any additional information? I've looked at some reviews and it appears 100mm has the slight edge because I was reading that 80mm is a bit of an interesting focal length...but I'd love that extra third of a f stop

    Thanks guys you guys all rox!

    I have the both the 50mm f/1.8 and the 85mm f/1.8 ... I love them both, but find myself using the 50mm one much more often. That's due to the fact that most of the pictures I take are indoors - and find myself backing up too much with the 85mm one. The 50mm is also smaller and lighter, so makes for a smaller camera if I'm going somewhere and only want one lens. (I think the f/1.4 version of the 50mm lens is a bit larger/heavier though)

    That said, if your main goal is to get something like head/shoulder portraits, you might consider the 85mm one. You'll get a little better looking bokeh (blurred out background) since it's a longer lens.

    Here's one taken with the 85mm lens:

    This was taken with the 50mm:

    and I'm 90% sure this was taken with the 50mm also:

    So, you can't go wrong either way with those. I'm not familiar with the 100mm one you mentioned so can't really comment on that.

    Thanks for the sample pixs. I had thought about the 85 or 100 focal length lens being a tad too long especially for indoor stuff. The trade off is that I would want to use that kind of focal length for some outdoor sports related stuff too, possibly in low light and the fast lens would help me indefinately...the 50 would be fast enough but not long enough for me...then again I might try to sock some money away each month for a year to get a one of those fast lens zoomers...

    Ah decisions decisions!

    I'd go with the 85mm. The problem with the 50mm is that you can get perspective distortion on head-and-shoulder shots, particularly with children. In addition, the 85mm has USM focussing, whereas the 50mm 1.8 does not. At f/2.8, the 85mm is among Canon's sharpest lenses - better than my 200 f/2.8L at any aperture. If you could swing the extra $80, get the 50mm for torso shots or for two or more persons in the frame.

    My opinion is that the 100mm on a 1.6 crop will be too long for indoor portrait shots and you may sometimes find it short in some outdoor sport situations. The 85mm would be better for indoor portraits but not very useful in sports.

    My advice is to get the 50mm f1.8 for now which is really really cheap and save your money, so you can get a nice 70-200mm zoom for sports later on. This way you have everything covered! ;)

    I have had all of these lenses and for the Rebel, I agree with this statement.
    Get the 50mm 1.8, it's cheap and best for portraits.
