Hi


<span style="font-size: 9pt; color: black; font-family: 'Verdana','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US"]I just got my 17-55mm and430EXII this weekend. Have the 28-135, 70-300 and 50 1,8 like you only different is that my camera is the 400D and I don&acute;t intend to go FF. Cash......<o></o>


<span style="font-size: 9pt; color: black; font-family: 'Verdana','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US"]My first impression is that colors/contrast is better than mymostly jousted 28-135 and autofocus was spot on and silent. Low light indoor shot only - it has been raining for two weeks ;-(<o></o>


<span style="font-size: 9pt; color: black; font-family: 'Verdana','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US"]There is a huge difference from 28 to 17mm on a 1,6 crop.<o></o>


<span style="font-size: 9pt; color: black; font-family: 'Verdana','sans-serif'; mso-ansi-language: EN-US;" lang="EN-US"]Just my 2 c&acute;<o></o>
