Currently I have a Canon T2i with the EF-s 18-55mm f/3.5-5.6 IS kit lens and according to the serial number it's the 2010 model. I think this is the 1st series and not the II. For awhile i've been looking to upgrade it to the Sigma 17-50mm F2.8 EX DC OS HSM.
I really like the idea of having a constant f/2.8 and always said if we have a kid that would be my excuse to buy it. Well come end of April we will have a new baby in our lives. After looking around I also noticed the Sigma 17-70mm F2.8-4 DC Macro OS HSM. I'm kinda torn between the two, but really leaning towards the 17-50 more since it has the constant 2.8 and right now i think that's more important to me than the extra reach. Although both lenses would be faster than the current kit lens at the long end, would it be more benificial to have the f/2.8 to go 2 stops instead of just the one.
I know a lot will say get a fast prime something with f/1.8, but i'm not sure if i'm ready for a prime, i really like having that zoom capability. I know when the kid is a new born having a prime wouldn't be bad to use, but i'm thinking more in the future as well when it starts moving around. I like that ability to be able to change distances quickly.
I do have a Yongnuo 565EX flash for shooting indoors so that will also help with not having something faster than f/2.8. For outdoor shooting at a park or where ever i have Tamron 70-300.
My budget for this is about $600, if it was up to the wife it'd be half that, but I told her that's not gonna happen hehe. Would love to hear your thoughts / opinions.
