I am still wanting to pick up some more lenses, but not sure what. I know I want to always be getting "better" stuff, but my checking account doesn't always agree. So, I'd like to maybe just think of filling the holes in my lens arsenal with things to compliment it. So, here's what I have
Canon EF-S 18-55mm f/3.5-5.6
Sigma EX 105mm Macro f/2.8
Tamron XR 28-300mm f/3.5-6.3
None are great, but they're decent. What would the next step be for an enthusiastic amateur who wants to upgrade to a lense? I usually use the Tamron as my everyday lense, but maybe a faster lense with a shorter focal length would suit me better?
What do you guys think? What would be my next lense step?
