You are right - there was an error in the specs. The 14-45mm has a min. focus of 0.3m and a max. mag of 1:6. Sorry for that.
The latter bug came in via Panasonic's statement compared to 35mm format lenses. The native mag is just 1:6 though.
As far as a retest of the 14-45mm is concerned - I don't think it's gonna happen.
I'm not even sure whether the lens is still in production. Over at B&H it is out-of-stock, for instance and it isn't sold anymore in the current kit offerings.
The 14-45 is still rather easy to find in the netherlands for about 245€ "in stock", maybe just existing stocks.
Remember I got mine for 99€, aaah should have bought a truck of these :-)
Honestly, I wasn't quite as impressed by the 14-45mm (nor by the 12-35mm).
I'd say that MFT still lacks a truly high performing standard zoom.
The 14-42 II is the probably best bet for the time being.
Hum. Would be interesting to test the 14-45 on the same body. I will say from the samples that the 14-42 looks pretty decent and punchy - or maybe it was the lighting that helped ?
The Pana 12-35/2.8 had potential but it was too under-designed to be stellar.
I'm still placing my hopes on the rumored Oly 12-60/2.8-4.
The problem isn't really to reach a sufficient performance but to keep the size and weight down.
The Pana 12-35 was too much on the latter side.
