I agree, the gx9 is pretty big on specs and has a more modern sensor. That would be my choice to at this price. Although that prime you get with this does give this a shout.
I'm sure the processing engine has been updated, but how are Olympus still peddling the 16mp sensor? Got to be about 8 years old at this point!
I do like this retro kind of rangefinderish styling. I'm also pleased to see that OM Digital are keeping the Olympus branding in cameras following all the problems of recent times. As a child I saved really hard and traded a Zenit E for a used OM10 and that became my pride and joy, went everywhere with me so I hold a soft spot for Olympus.
Good saving from the RRP. I would suggest looking at the Panasonic GX9 at this price point (with kit lens) as an alternative. Higher MP at 20 vs 16, viewfinder, 4k (which this also has), etc. You do get an extra lens with this deal though.
