The former owner of the ePM2 also had a few other lenses to sell, so I relieved him of those this week. The home equity loan went through, so while things aren't fantastic financially at least they are more clear! With that last bit of gear I'm ready to stop for a while, since the missing piece in my mind (Samyang's 12mm f/2) is not on supersale now anywhere and it's too new for owners to let go of their copies.
While I find the Samyang 7.5mm fisheye appealing (as I did with the G7) the bargain BCL9 is a 9mm f/8 fisheye that will stand in just fine for most applications. I had figured on 7.5/14/20/30 as the primal set but I've had a soft spot for the 17/2.8 for several years, so its return makes the 12mm a better fit.
On the Pentax side the kit has slipped away. I still have the 10-17 fisheye which hopefully will find a new home soon. The micro4:3 replacement set has taken most of the Pentax funds so taxes and medical bills still await - but some improvement has taken place with the gear swaps. I still have the 28, 50 and 135mm primes also; the 28 isn't needed for the Oly kit but fast 50 and small 135 could see some time there. The 300mm mirror lens might be quite fun as well!
