Here is an impromptu wish list for something all Olympus
EM1 ergonomics and features
zoom f2.8 over range 12-40 and 25-150 - save me doing so many lens swaps in the mid range 30-60
an f2 or better portrait short zoom 30-80mm
a macro convertor ring which maybe crops the frame for best results
Depth of Field / Focus auto bracketing for macro
Focus Lock / Focus range lock combined with focus peaking
Blue tooth speaking settings
Auto file back up and "keeper" double back up. Auto delete all non keepers from earlier shoots when docked. USB memory stick dump possible.
In reality though today, what is there as a system for me?
Firstly there really is no fall back short of the 16mpx sony chip ,and then with viewfinder built in. Hence OMD.
I see very little point now in the em1 because the swd lenses are expensive second hand, so expensive in europe that hand baggage imports of new lenses from the states or far east are cheaper. People think they can hold their value and now there is a new body to take them- if not excell with them screwed on- the prices for the two swd zooms which do it all are way too high. The 12-60 used on ebay and amazon and our local finn.no are around 800 euros, which is more than the new mFT 12-40. When a new oly fast zoom comes out in the range say 40 to even 120, then the golden ed pro zooms of old will be foot notes in the book of Olympus's digital adventure.
A better bet is now loosing value and being sold on some nice E3s and E30s, the venerable 14-54 mrk II. The mark one is also being punted on E1's and hundred series cameras. These packages are around 400 to 600 euros, and you could pretty much dump the body in the bin as far as i am concerned. If you are getting the mark II plus some other lenses of note such as the wide zoom or 75-300, then that is a bargain. People are a bit prone to want to sell their whole system if it is pre E5 E620. For latter day cameras with quality lenses the lenses are usually quoted seperately after a bait price on the body with the kit lenses.
Even the mark I seems to work on some mft bodies, but it is thed mark II 14-54 which was contrast detect optimised and has a second to none manual focus. This works across all the ep compacts from 3 vintage, and the omd range of course. It is a more compact lens than the 12-60 and is actually faster in the mid to longer range on f stops.
But then it lacks that nice eq 24mm for lakeland shores with mountain panoramas, city scapes and weird candids. Well on mft there are good wide primes and you now get amazing iso performance compared to four thirds E series cameras so you dont need a soft wide open 22-28mm range. Also people are far more consumerist about the fashion of system compacts, and dump kit cheap to make the down payment on their next bling thing. Often that means an earlier PEN body with one kit lens or two, but with one quality wide prime or the 45mm prime in the package or highly negotiable.
That is the good thing about PEN, panny g series and now OMD: lots of consumer fashion idiots buy them, learn they need a good prime, and then realise they are using their iPhone /Galaxy for actually taking piccies, thus selling off as above.
Kodak by name only, have amazingly enough gone 16mpx mft and have their own interesting zoom lens which is not super fast but nor is it a slow dog kit lens. Also they are using IBIS , so the lens can be cheaper than a panny and you can retro on anything. The "kit" zoom has a good range and if i remember it was f three and a half to the arbitary five point six, not that shabby if ISO is up to the job and ibis works as well as oly. Also they launch with an at first comical Hubble competiting 400mm (=800 in old money!) Which could be to mft was the "Bigma" was to FT. If under 300€ it could have the last laugh not just for those awful twitching "birders" who clutter many a photoforum with this week's brown bird sitting in a tree , or eagle half hidden by pine tops, or vulture silohoute against blue sky. Bravo "kodak". Eastman may guffaw from above.
