Ok cost is an issue for me considering im only 15 and im not loaded. I have a 30D and want to now which wide angle you think I should buy. The choices the Canon 14-40 f4L, Sigma 17-70 f2.8 macro, Tamron 17-50 f2.8. I know the sigma and tamron are much cheaper so already im leaning that way, but if you think I should wait and save up for the canon thats a possibility. I was wondering if anyone has tried any and what they thought of it I look through the sample gallery for each lens and all the picture look awesome. I'm not a big pixel peeper but I do want high image quality sharp pictures. The final question which will give the most bang for the buck? Thanks for reading and look foward to your reponses.
Canon 17-40 f4L
