The difference between Olympus 4/3 and MICRO 4/3
Overview
M4/3 is the abbreviation of Micro 4/3, which means Micro Four Thirds system, also known as Micro Four Thirds. This system can make SLR cameras as thin and convenient as card cameras. The micro 4/3 system uses the sensor specifications of the 4/3 system, but cancels the mirror and pentaprism that traditional single-lens reflex cameras must have, and directly focuses the image digitally, with a compact size and a lighter weight. Design advantages, while the image is close to the quality of a single-lens reflex camera.
The flange distance of the Micro 4/3 system is about half of that of the original 4/3 system. On the premise of retaining many devices similar to DSLR (such as dust removal device, low-pass filter, etc.), the thickness and thickness of the camera can be effectively reduced. volume. The compatibility with the original 4/3 system lens uses the original 4/3 system lens through a dedicated bayonet adapter.
The M4/3 system continues the large-size photosensitive element and interchangeable lens design of DSLR SLR cameras, and at the same time absorbs many advantages of consumer-grade digital cameras, such as the elimination of reflectors and the use of electronic viewfinders, and the use of consumer DC focusing methods to shorten Flange distance and overall weight, etc.
The M4/3 mirroring distance has been shortened by nearly 50%. The diameter of the lens outer ring has been reduced by 6mm. The number of electrical contacts in the lens has increased by 9 to 11.
Is Olympus 4/3 compatible with Micro 4/3?
4/3 lens can be connected to 4/3 system and M43 system (via adapter ring)
Otherwise, no, that is, the M43 lens can only be used by the M43 system. The flange distance has been reduced by 20mm, and it is impossible to focus at infinity.
The difference between Olympus 4/3 and OM mount
OM is the mount for Olympus 135 film SLR cameras, and OM4/3 is the mount for Olympus digital SLR cameras. OM lens can be transferred to OM4/3 for full manual operation, OM4/3 lens cannot be used on OM mount.
