Even though I love my little CV APO-Lanthar 180/4, I may someday have to get the 180/3.4.
Meanwhile, I've now got a Summicron-M 28/2 on the way. I already have the latest Elmarit-M 28, so I'll be seeing if the extra stop (and, depending on who you ask, little extra "something") that the Cron has is worth the price and size/weight difference.
If it is, the Elmarit will go, and probably one of my 35mm lenses as well.
