    if you are on crop, 85mm with a 3-5m distance from your model for upper body is fine.

    Crop is for crop sensor or APS-C sensor. Basically the sensor size is 24mm (or i think 22mm for canon) instead of 35mm (full frame).

    Your camera is crop sensor.

    On Canon's cropped sensor, your 85mm lens will behave as a 136mm lens (85 x 1.6). For all the lens, you would need to multiply a 1.6 crop factor. I would not really recommend a 135mm lens in your case, it might be too tight and you might need to stand way back.

    thx for the reply, actually i am just planning to get the 7D. in this case, i think i will need to consider the lesser crop cameras or stick with the 7d after read up more about cropping

    thx

    The TS wants to shoot from 3-5m back. 85mm should be about right for that distance on a crop sensor.

    Canon's range of DSLRs are either with a 'cropped sensor' (crop factor of 1.6) or 'full frame' (same as film SLR - no crop factor)
    A similar situation exists with the other brands.
    So there is no "lesser crop" cameras
    Hope that helps.

    To throw in the confusion, apart from 1.6 crop and FF, Canon really has a "lesser crop" aka the1.3x crop ( hohohoh .. )

    Actually there are 3 in Canon. You forgot about Canon's 1D series' 1.3x crop factor sensor.

    So TS:

    For Canon DSLRs, there are three sizes of sensors currently available.

    1) APS-C, which has a crop factor of 1.6x [1100D, 600D, 60D, 7D, etc] - basically your entry to enthusiast DSLRs
    2) APS-H, which has a crop factor of 1.3x [1D]
    3) 'Full frame', which has no crop factor [5DmkII, 1DsmkIII]

    hope I'm right!

    on a 1.5 crop, a 50mm or even 35mm is sufficient if your working area is 3-5m and doing waist up shots .... with a 85mm on crop sensor , you will likely end up with head + shoulders shots

    just bring your camera to the shop and try out for yourself and decide what u are comfortable with

    My personal preference is to go for 15-85, since I like to go as wide as possible, and 85 is pretty sufficient on a crop factor cam like 7D.

    But that's just me

    i hav went to the canon showroom today, trying some of the lens.


    i had tried the 200mm lens with 60d, to my superise that is something that i want, i thought just get the 85mm or the 135mm lens will do. however the 200mm is the only lens that able to close up to that edge that i want

    For convenience wise, 18-200mm is a good lens... quite sharp too. However don't expect it to give similar sharpness as compared to 15-85mm.

    Another alternative would be to get the 15-85mm lens + 70-200mm f4L (if possible, get the f2.8L) and this combination will be perfect.
