A) Dimensions
The X100vi is 128 x 75 x 55 mm/
The OM-3 is only longer by 9mm, higher by 11mm but thinner by 10mm and lighter than the x100vi by 30g.
BUT the OM-3 battery life is 590 shots vs the 100vi 450 shots (31% more battery life).
OMDS could have made the OM-3 smaller by reducing the battery life but I guess most users would prefer a longer battery life.
Same for Full Frame cameras. Do you know any Full Frame camera about the size of the OM-3 with the same battery life and IBIS 6.5.
Battery Life and IBIS usually take up the most space in a camera.
Anyway, I also do not it is a good idea to have a camera as small as some of the older M43 cameras as generally a lightly larger grip is nicer to hold.
For my A7CR, the additional smallrig cage is almost permanently attached as additional grip.
B) Nameplate
What value or benefit does it offer???? My friend just complained that Canon EOS-M became obsolete and another friend complaied Nikon V series mirrorless cameras all became obsolete even before M43!
C) Sensor size?
What benefits does it offer? As of these 2 years, all my shots are for safekeeping and social media.. I prefer to have a small sensor for smaller file size and fastor read out speed to reduce jello effects and faster FPS, especially when taking wild life.
If based on the 3 points you throw the OM-3 in the rubbish bin, I think you should throw your brain into the rubbish bin too! LOL
• OMDS OM3 size Dimensions, Approx. 139.3mm(W) x 88.9mm(H) x 45.8mm(D) almost as big but sensor so small
Film era OM3 Dimensions 136 × 84 × 50 mm (could take 24mm x 36mm negatives)
• Name plate brand : OM System (Not Olympus)
• Sensor size of OMDS OM3 : Obsolete MFT
In view of just these 3 parameters, the OMDS OM3 can throw in the rubbish bin. Worthless overpriced junk.
