Current set up: 60D (yes, I regret not getting the 7D
) with 10-22, 15-85, 100 macro, 70-300L. Main interests are wildlife, birds, landscape, macro so happy with my lens collection. Problem: I am now viewed as "the photographer" in the family so am expected to get general family shots plus we have 2 fast-moving grandkids. Nothing in my lenses is good for indoor/lowlight photos or videos. Was going to ditch the 15-85 and get the 17-55 which on the used market should cost me a net of $300. But, now the rumors of the new primes 24 and 28 have me second-guessing. Adding one of these for the "family" situations would cost me $800 rather than $300 because I would need to keep the 15-85. Any thoughts to share out there??
