If you ’re shop for a new camera , you may have come across the terminus Micro Four Thirds .
Keep read to learn everything you need to know about the Micro Four Thirds arrangement , include what it is , how a craw factor affects your image , and how Micro Four Thirds cameras compare to other cameras .
What is a Micro Four Thirds camera?
Micro Four Thirds ( MFT ) is a mirrorless , exchangeable - lens camera system that was first released by Olympus and Panasonic in 2008 .
The image sensing element in a Micro Four Third camera beat 18 x 13.5 mm and has a 17.3 x 13 mm imaging surface area that can be compare to the size of it of 110 film . Micro Four Thirds cameras also use a 4:3 scene ratio as oppose to the 3:2 ratio used by APS - C and full - frame cameras .
As you might have already guessed from the name , the Micro Four Third system share the same image sensor size of it and spec as the Four Thirds system found in DSLRs . However , the Micro Four Thirds arrangement is smaller , leaving no way for the mirror box and pentaprism need for a DSLR . This allow Micro Four Thirds camera to be more compact and lightweight than their Four third base - toting counterparts .
The lenses are shorter and more lightweight than lenses build for Four Thirds cameras too , thanks to the reduced flange aloofness .
Mirrorless cameras that make employment of the Micro Four Thirds system typically include an electronic finder . How these viewfinders compare with the optical view finder find on Four Thirds - power DSLRs depends on the precise declaration and refresh charge per unit of that particular EVF but , generally speaking , the character of EVFs has increase dramatically since the Micro Four Thirds scheme first tally the scene 15 geezerhood ago .
Micro Four Thirds vs other systems
Micro Four Thirds camera are well fit out than cheaper compact digital cameras and bridge camera that carry small sensing element and fixed lens of the eye .
However , the persona sensors found in Micro Four Thirds cameras are also lowly than those get in full - frame and APS - C camera . This cause Micro Four Thirds tv camera to experience a 2x harvest divisor that affects the focal length of any lens you attach to it .
APS - C tv camera have a smaller craw gene of 1.5x , while full - soma cameras have a crop factor of 1 ( equivalent to 35 mm photographic film ) with the full detector perfectly exposed when paired with a full - frame lens . This means that a Micro Four Thirds tv camera will produce an image with a surge - in effect compared to a full - frame photographic camera .
To amend this , you ’ll need to multiply any lens ’s focal length by its crop factor when shopping for lens system . This will give you the equivalent focal length ask to snap an mental image with the same field of view as a 35 mm – or full - figure – photographic camera .
On the flip side , Micro Four Thirds camera are loosely much cheaper than their full - chassis opposite number . The lense are inexpensive too , mean you’re able to build a braggart lens collection with less money .
