Well I might be alone in this, but I'm very underwhelmed with today's announcements. I'm convinced that 90% of "new" features of the OM1-II should have been applied in a firmware update to the original OM-1 (as OM Systems promised in the launch of the OM1 2 years ago, that they would continue it's development by firmware). From what I've read online, it seems that door has been closed by comments from OMS. Aside from a few very minor feature and bug fixes to the OM-1, that never happened. I get that the increased internal dram buffer allows more shots in the buffer, but I never hit that anyway with my OM-1 (no where near in fact), although I'm sure others mileage will vary.
Whilst my original OM-1 is the camera I paid for 2 years ago and is still as good, having the door slammed in loyal users faces in as much as if you want the new features then stump up an additional £2,200, is really quite jarring, especially as I've been with M4/3 for nearly 10 years now and became accustomed to Olympus's stunning firmware programs. It seems OM Systems has a very different model and that is fleece and bleed it's user base as much as possible.
Even the new 150-600 lens which we all know if based on the Sigma unit, has suddenly doubled in price with an OM Systems label on it from what it can be purchased for on the Sony/ Canon/ Nikon mounts. I get they might have "optimised" it's design (although it's still a colossally large and heavy lens for M4/3), but really - double the price ??
As I said before I won't be selling off what M4/3 equipment I currently have (as it still works), but personally, I think that's me done for anymore investment in OM-Systems and perhaps the M4/3 system as a whole. If i did buy anything else M4/3 related, I can only see it being the G9 II for it's stellar video abilities, but then my Nikon Z8 does pretty much all that (and 8K and internal Raw) for a 250g weight penalty over the G9 II.
I think my preferred wildlife kit would be either my current OM-1 with the 300mm F4 Pro and 1.4X TC, or my Z8 with the 180-600 (in DX Mode - 270-900mm), @ nearly 20mp. If I changed to the new OM-Systems 150-600 then the combined weight with my OM-1 would be 2,699g where as my Z8 with the 180-600 is only 160g heavier at 2,860g (and a pretty much identical weight if I use my Z7 II body instead of the Z8). True, the OM Systems lens goes to 1,200mm, vs 900mm on the 180-600 Nikon (in DX Mode), however the Nikon lens is nearly £1000 cheaper !
I've been pontificating for a while should I go all in with Olympus / OM Systems or flesh out my Nikon Z system. I think today has made up my mind. Don't get me wrong, I like the equipment I currently have and it won't be going anywhere soon, and If some of you are really excited for what's been announced today, I'm very pleased for you, it's just after 2 years I expected more...much more. Any future money on spend on my "hobby" certainly won't be going to OM-Systems, which I feel very sad about as I loved Olympus.
