    wow.. useful review
  • -go crazy 6y

    hey, i want to buy the 24-105mm but i dont know if the 4F is enough for low light.. i suppose the L lens elements are brighter though.
    & is IS a good alternative to the 2.8F ?
  • Vincent Pang 6y

    -go crazy good enough if u have 5D MK II :) boost up the ISO... NO IS is not an alternative nor replacement for f2.8... it's just handy to have IS when you are shooting at the tele end 105mm @ 1/30s :)

    f2.8 will give you a faster shutter but at the cost of thinner DOF. Because of that, i still shoot at f3.5 - f4 to be on the safe side.
  • -go crazy 6y

    Oh DoF is not an issue for me, i actually love a good blur effect for portraits! i consider buying a canon 40D. i think the 24-70 is better for my needs. thank you!

  • Vincent Pang 6y

  • Tim Newman 6y

    I love my Tamron 17-50mm on my xti!! But I'm selling it ONLY because I'm moving up to a 5d mark II. I feel I need that range though, I can't afford to buy the camera and a canon 24-70 f/2.8 (which I would choose over the 24-105 mainly for the 2.8 aperture) I am going with the sigma 24-70mm 2.8.

    What do you think about the tamron 28-75 f/2.8?
  • Alberto Feltrin 6y

    to Tim Newman

    do you mean the new sigma "HSM" or the old one "macro"!?! because the new "HSM" version costs as much as the canon one!
  • Vincent Pang 6y

    Tim Newman i found the tamron 28-75mm f2.8 to be slightly sharper and more accurate in AF than the sigma. I was told it is the same as the 17-50mm f2.8 except it's 28-75mm

  • Alberto Feltrin 5y

    yes, i use it @f9 in party shots and it is amazingly sharp! and it's really cheap!!!
  • Tim Newman 5y

    I was actually able to afford getting the 24-70L back in September. Love it and works great on full frame!

    I bought SD780IS about a month ago and I couldn't have been happier. I've taken about 500 photos so far and 50 video clips and they're all perfect!

  • Alberto Feltrin 5y

    lenovo_T500 it's a great lens :)
  • Joe Papagoda 5y

    What are the sigma lenses made from? The material looks so different than others.
  • Alberto Feltrin 5y

    it's a different finish, however, they are changing it in the new ones.. look farm5.static.flickr.com/4122/4911619303_9a1c561a73_b.jpg
  • Vincent Pang 5y

    Joe Papagoda not sure wat's the material, look like some sort of matte coating which has tendency to peel after some use. It's great that they are changing the finishing as pointed by Alberto Feltrin.
