I've had the E-M5 Mk 1 for about 5 years now after a trip to Hawaii with my G12 and lamented a viewfinder due to sun, glare etc.
Was all set to return to SLR but Digital, when an extremely enthusiastic supporter of the E-M5 sold me on the virtues of it.
A return trip to Hawaii vindicated all he said about it and I've never looked back.
Water resistance is a must as I love the misty moisty days and those are the times when the landscape oozes its charm. Hawaii had many showers, downpours and whilst not deliberately exposing it to those for extended periods it got damp often.
I realise much of what I'm writing next is common across many cameras.
It's compact, light, robust in my view, big hands don't always hit the button I want but happy with the compromise.
Shortcuts and Function buttons are there and I use them often, it's so quick to change settings.
Live-view is excellent, allowing for adjustment before shooting.
I bought it with the 'extras' 12-50 macro lens which suits my casual walk about use.
I also have a 60mm macro, and am just playing with the 75-300 mm. Early days on that one.
I have a Raynox DCR250 that I bought for my Canon G12 and this fits on E-M5. If you want to get up super close it does with excellent results.
I prefer fully articulated screens which Mk2 has, but I get by (just). The G12 spoilt me.
For my use it's focus is fast enough. Not always good around kids, they move quickly!
I do miss my old SLR's, particularly my Zeiss, sigh. But images are good enough for my use.
I think the images speak for themselves.
I watch in awe these bird shots, but there are some quality ones taken with the 75-300 which makes me try harder. Thanks bidkev
My brothers Mk2 is nice and he has the 12-40 Pro lens which is Nice.
When Mk3 arrives, we'll see. Might trade.
Would I change my mind knowing what I know now. Unequivocally No.
