I haven't watched the review yet but from your points I can see and understand how the OM-3 can appeal to you. It looks to be a higher grade OM-5 with the additions of Computational features and build quality but smaller the ln OM-1 and a bit more compromised (mainly the EVF and the mechanical shutter (6 FPS).
I would be quite interested in this camera too because they fixed/added all the disappointments with E-M5 III/OM-5. It would be quite a wonderful backup/2nd body for a OM-1/Mark II.
For me I will wait for the price to come down because OM-1 can be had for around 1.000 £ or even less used if you wait long enough and I am not willing to pay extra just for the smaller size. Also I will wait for 3rd party manufacturers to come out with L brackets or grips because I won't find it comfortable to use the flat ergonomics with my f 1.2 PRO or 40-150mm f 2.8 PRO lenses as these two would be the most likely lenses I would use the camera with.
To bad because I am going to try to get a trip or two to the coast to photograph Puffins and I will need a 2nd body alongside my Oly OM-1 and 100-400mm f 5-6.3
Another good setup would be for macro (for me) with the smaller Godox V350 flash and 60mm f 2.8 Macro.
I would be very interested in the Mark II of the 100-400mm for the Sync IS because I am so dependent of Image Stabilisation and it's one of my biggest frustration with my current Mark I.
I don't think I have much interest in the WR version of the f 1.8 primes unfortunately because I have the f 1.2 PRO if the weather is that bad and if it's not raining I think would have more fun with the Samsung NX500 and the primes (once I have all of them). Sorry OMDS ... You missed the trimming with me on this.
PS. The bigger question for me is Did OMDS tried to fix the S-AF issues of the Stacked 20 MP sensor since it's been an issue on both OM-1s AND have they tried to improve the C-AF?
Because they are not competing at the level of Sony, Canon and Nikon right now and they should/need to. They really need to catch up and keep up if they want to stay relevant and competitive, survival is not enough.
Ok, so I have watch Chris and Jordan's video on OM-3 and I have somewhat mixed feelings about the camera but not much has changed from what I have said above. But first let me say the positive things:
*The camera is gorgeous looking and I am sure it feels like a good old OM film camera (I have owned one briefly and I loved the feeling of it).
*The have fixed my problem with not being able to reassign the On/Off switch IF you use the 1/2 switch as the power switch so you are not losing functionality there.
*FINALLY, unlike with OM-5 and E-M5 III, OMDS has put every single software feature from OM-1 II into OM-3 so there's no longer a feature disparity between the top and midrange camera.
*Same battery as the OM-1
*The new OM-1 UI system and menus
*The new selectable slow-er electronic shutter speed from OM-1 Mark IIQ
But that's about all the good news. Here some of the not so good news:
*No official grip add-on so we will have to wait for Smallrig and other 3rs party manufacturers to add a grip at the front of the camera
*The EVF is (from the specs I could find) from E-M10 Mark IV as it has smaller signification them OM-5 and even smaller them E-M5 Mark III and E-M1 Mark III
*The IBIS is not from OM-1 or Mark II and it seems to be on park with E-M1 Mark III
*The shutter mechanism is a new type with slower 6 FPS compared to 10 FPS on OM-5 and the buffer is reduced from 143 RAW to 90 RAW.
*The price, basically you pay more then OM-1 Mark II to get less then OM-1 Mark II with no additional feature aside from the colour mode dial and a new Profile adjustments a'la Fujifilm.
*Single SD card slot even though it's a thicker body then OM-5 (I'm guessing the stack sensor requires a larger and better heat management with scanning so fast and frequently.
I'm sorry OMDS but this camera is not worth more 1.000-1.200 £ at most for me with what it offers. It's small-ish but not E-M5 small, it's fast but very much hampered by the buffer size, the colour profile adjustment look fun and interesting but if they are not supported in Lightroom WITH the adjustments I can make in the camera it's hardly useful for RAW shooter like me, I could live with all the other specs but not at the asking price.
I would be better off with an OM-1/II or even a G9 Mark II.
It is a very pretty camera and I could easily see myself as my travel main camera, street photography and personal fun camera ... But again, not at the asking price.
In some ways OM-5 is better then OM-3 (EVF, buffer, default grip, weight and size, IBIS).
