Hello buddies, I badly need your input here as I searched the forum and found no formal discussions on it.
As I'm about to go for a travel, it's a good opportunity for me to add one more lens to my collection. In fact I consider it as the first lens for my serious line up. So no need to consider what I currently have at this focal range.
The prices of the two being similiar so it ain't a factor here.
Optical wise I have no idea as I can hardly find reviews on the two esp on the new EFS 15-55 F2.8 IS so your comments are greatly appreciated.
Focal range wise is where troubles me most. I have an old 80-200 F2.8L which i'm pretty happy with but sooner or later i'll trade for something better (lighter and IS). so 17-55 leaves a gap inbetween. and i'm not too sure if i will feel in need of anything shorter than 17mm on my 20D in future, i.e. 27mm on fullframe which is an awkward focal length to me.
on the other hand, though 24-105 covers standard to tele together with my 80-200 for now, i may need to add another wide angle, most probably another EFS or Sigma for APS sensor.
Mount: i'm no professional so no one wants to see prints of my photos bigger than A3 including myself. therefore i'm not going to fullframe at all (the Nikon pros are shooting APS sensor out there too). besides, by the time i can afford 2nd body, APS sensor will be much better. so does the 24-105 F4.0L IS staying permanently on an APS camera make good sense to you?
Line up: i consider this lens to be the first serious lens to my APS sensor line up in the long run. the EF 80-200 F2.8L could be traded in in future for something lighter with IS. as an amateur, my goal is to build up something like:
2 APS sensor bodies
3 zooms which deliver pro quality at A3 size
a few primes (perhaps the TS-E lenses, i know the focal lengths become wierd on 20D).
i'd like to see most of my lens investments go into landscape, architecture, portraiture and street photography. no birds or wild lifes or sports. therefore if the tele end is not long enough, it's not a big issue to me.
I now have two possible line ups in mind:
a: EFS 17-55 F2.8L IS, in future add EFS 55-105? F2.8L IS or EF 70-300 DO IS (perhaps another wide angle if necessary). i think this is the EFS trio Canon offers for 20D line users. Limition: one 17-55 is not as capable as 24-105. so when i wanna travel light (maybe within town), i'm not sure if one 17-55 is enough.
b: EF 24-105 F4.0L IS, in future add another wide angle and replace my 80-200 F2.8L with EF 100-400 IS or EF 70-300 DO IS (longer coverage but i don't have an F2.8 zoom).
what do you guys think?
Thanks a lot a lot.
