Well, the idea of a second affordable mid zoom is growing on me. I had a brief ebay search and found lots and lots of 90s and early 00s mid zooms (28-70,28-80,28-105 a.o.) at ridiculous prices. Heck, I can buy one even for fun. None of them is particularly fast, but wth, if it turns out to be at least decent in medium light, I might end up keeping the 24-70. What do you guys think?
