Here is another suggestion. I have two first generation OMD EM5's. I am selling them to finance an upgrade to an EM5ii to back up my PenF. They are in excellent condition and you can have one for $100 and I'll throw in a very good guidebook. Find a used lens on eBay or one of several used camera dealers (I can recommend some that I have used) and you are in business. The advantage is that for very little money you are into the Olympus system and you can see how you like it. The EM5 will do what you want it to do and if you decide to upgrade you can keep it as a backup. The only negatives to this plan that I can see are that the EM5 is a 16 MP camera and the EM5iii is 20 MP (you can research the debate about how much difference that actually makes); and if you decide to move up to the EM5iii I think (but am not sure) that the menu system has changed a bit...
Nice to see you back and still weighing the Oly Cameras and Lenses!
I think Rgone's offer is a great way to get into M4/3 & Oly. The EM-5 is a great camera to get the feel and even though 16 MP, the images it produces are tops. Oly menus tend to vary a bit throughout all the cameras, but a very easy transition for the majority of settings, with only the newer stuff needing a little acquaintance.
Really $100 hardly gets you a nice used P & S camera. However, now one can put a bit more into getting the glass you'd like to use - and carry forward when upgrading to a newer Body.
If he is still offering... I would take him up on this.
Re: manuals, knowing and assuring - for me there is a point where TMI overwhelms.
I never tire of the adventure of 'learning', so no matter how I delude myself into 'expert'ness, I'm always excited when I learn something new, photography included.
BTW - Just got a Pany Lumix 12-60 f3.5-5.6, and except for the fixed f2.8 of my 12-40 Oly Pro, I'm finding it as overall 'Great' in IQ - and it's really 'handy', comfy like my Oly 14-150, with a nice edge in the lower FLs.
Highly recommend as a consideration - I almost never use my 12-40 now cause 40mm causes too much lens swapping - distracting and annoying for me... Was a 'Kit lens for Pany, but well-built and higher actual performance than expected.
