I've been juggling my lens line-up of late as well. Sold off my 24-70 F/2.8 and my 17-40 F/4 lenses, and just have 3 primes (Sigma 35/50/85) and a 70-200 F/4 now. Still wanting to pick up a 50L, and maybe upgrade to a 70-200 F/2.8 some day. May end up looking for some wide-angle lens too. But I digress... Back to them mirrorless cameras, I guess.
