Just mentioning the pancake Lumix 12-32 3.5-5.6. It’s a surprisingly sharp for such a small light package, and are available for bargain prices. The construction is not going to win awards but the images might.Interesting idea, I can see some use for it as such. Mostly to camouflage a suitable digital cameras in a "retro" environment, for those that partake in such. That on a brown and/or black and silver house with a thin leatherstrap should go a long way fitting in.
I have been informed that the PL 9 mm is in stock no earlier than October up here, so that is somewhat of a bummer. On the other hand, I am down to that and the Oly pancake 14-42mm on the "Want" list, so there is always that. Stumbled over rumours that the latter has the same cable band issues that the Oly 9-18mm has, so now am a bit leery towards it.
If I should add anything, I fancy something that is not made, a decent enough 12-40 pancake.
It should be in the vicinity of the PZ14-42 or even slightly more protuding collapsed, but no bigger in diameter. Power zoom optional, but I live well with a manual one. F-stops in true kit-form, 3.5 -5,6(ish). Preferably weathersealed and as light as possible, 46-52mm filter tread. Metal mount.
