in terms of IQ wich one is better?
« on: February 10, 2012, 10:25:02 AM »
Hi all, i'm looking for a wide angle for my 5D MKII, i find 3 near the money i want to spend, i prefer primes than zooms, but ...

Canon - Objetivo EF 24 mm / 2,8  (quite old)
Canon - Objetivo EF 28 mm / 1:1,8 USM
Canon - Objetivo EF 17-40 mm / 1:4,0 L USM (in some reviews say it's better than the other two)
Thanks in advance, Gonzalo

Get the 17-40. You won't regret it. Its wide angle capabilities cannot be matched by the 24mm.
(There is a huge difference between 17 and 24mm)

The 17-40mm is definitely a popular lens. In terms of which has the "best" IQ, I don't know. Of the three, the 24mm f/2.8 has a slightly better MTF chart (on Canon's site), but MTF doesn't equate to image quality, since there are many other things like color saturation, CA, vignetting, distortion, and bokeh that all affect the way an image is perceived.

If you want the wide angle for landscape, I think you'll find a lot of people voting for the 17-40. If it's more for street photography, you'd probably want a faster prime. There are also some interesting specialty options, for example if you don't care about autofocus or filters, there's a Samyang 14mm f/2.8 that is about 1/5 the price of Canon's.

Anyway, as always, the choice is up to you, but I hope this helps.

I find that for street the 24-105 is ideal on a ff

I use the 17-40 for kandcsapes too, with it shutdown to f/8 or less the IQ is very respectable

It is a difficult choice.

Even the simple ( ::) ) choice between zoom and prime is not straightfoward
