Hi folks. I want to know if it can seriously be justified replacing the 18-55 IS with the Tamron 17-50? I also own a 40mm 2.8 which I like as well as a 50mm 1.8 that I also like. I know the Tamron is a good lens, but is it worth it considering the lenses that I already have. I had a similar post about the sigma vs tamron, now I would like to know if it is actually worth dropping $500 considering what I already own.
Do you like wider apertures? If so, then replace teh 18-55 with something with constant aperture, like f2.8, in a light zoom. If you can't do that, then frankly, there's no sense in "upgrading" for the cost, as the 18-55 is actually a very good lens, it's just kit, so it gets less attention than something that is nearly the same, but costs $500. In my book, an upgrade better have something that really impacts the physical limitation or ability of your setup, such as going to wide aperture as a potential, for it to be an actual upgrade. Otherwise, you're just throwing money away and getting some experience with something different, but you're not gaining a physical upgrade.
