Looking at replacing my 40D kit lens with the 17-55 EF-S IS USM f2.8, or supplementing the kit lens with the 70-200L IS USM.
my query is, will I notice a significant improvement with the 17-55, or should I keep the kit lens and supplement it with the 70-200L?
I am taking the family to Europe end of the month and want to make the purchase beforehand.
Advice appreciated.
