Unless you have a specific shot in mind, you could leave the 90mm at home and your back will thank you. Although the Tamron zoom's range is covered by the Sigma, you'll appreciate the wider fixed aperture, and it should make the better walk around lens especially if you're using the flash as a fill light.
Have fun and stay relaxed. regards, Anthony Farr > -----Original Message----- > From: Amita Guha [mailto:[EMAIL PROTECTED] > > I mentioned in the another thread that I'm attending a wedding outside > Detroit this weekend.
