I'm sure you are all over the "What lens should I get?" question, but if you'll indulge me for a moment, I'd appreciate it.
I am on the newer side of photography, Canon owner for about a year and a half, and have only been 'serious' for about 6 months or so.
I have 2 crop bodies, a Rebel 2Ti and a 40D. So far my lens corral consists of 18-55 kit, 50mm 1.8, 28-135mm USM, 75-300mm 3.5-5.6.
I would like to step up to a fast lens. Currently I don't have a specific style, I enjoy street photography, some cityscape stuff, some people/candid, some low light areas, and I shoot my sister's running team races.
I have a friend who has a 24-70L 2.8 and a 70-200L 2.8 IS that are for sale. I know I don't NEED a new lens, but I have the opportunity to upgrade with glass that I personally know and I don't know how long that will be around.
Any input on a direction? Am I just falling into the GAS trap? I love the ability of the 50 at 1.8 in low light and my other lenses can't hang in that respect.
Thanks in advance for any input.
