Default please help me pick one (lens)

I am on the fence deciding which lens to choose?
http://www.adorama.com/CA28135ISUR.html
which has a 28-135mm
or
http://www.adorama.com/CA18135ISR.html
which has a 18-135mm

They are almost the same price......but the 28-135mm....looks like the quality might be better than the 18-135mm.
Though i am leaning towards the 18-135mm.....because of it's wider angle 18mm

Could anyone please give me some input on what they would choose?
thank you all
Leo

If I was looking at the lens being a "one and only" then I'm not sure I could do without an 18mm start point.
Of course, much depends on what you plan to be shooting.

First, the obvious. The 18-135 is an EF-S lens, so it only projects an image the size of an APS-C sensor. Therefore, it would not work on 'Full Frame' or APS-H bodies, just APS-C bodies. Also, the 28-135 has a USM AF motor, so it will be quicker and quieter.

Then the optical characteristics. The 28-135 has less distortion, though, of course, it doesn't go as wide. Also, where their ranges overlep, the 28-135 has less vignetting, and less chromatic aberration.

I was kind of leaning towards the 28mm the build quality looked better.....though the wider angle of the 18mm is appealing as well.
This will be my primary lens.
I currently have the Canon EOS 500D and 3 lenses
EF-S 18-55mm IS kit lens
EF 50mm f/1.8 II
EF-S 55-250mm f/4-5.6 IS II
and a Canon Speedlite 430EX II

What is it about your current kit that you're not happy with?

Well, between the two you listed, the major difference is the range from 18mm to 28mm. You can find out how often you use that range of focal lengths using a program called ExposurePlot that you can download for free. Give it a try, and see how much of a handicap it would be to get the 28-135 instead of the 18-135.

to be honest i had almost the same set up 550d plus the 2 lenses. I got myself a sigma 17-70os (could not afford the canon 15-85) and just recently due to a bit of luck i got a 70-200f4isL I find this a good combination.
