Smaller sensors are therefore cheaper to make than bigger sensors. Like I said there are other sensor sizes and camera types, but these are the main ones. Micro four thirds sensors are smaller again, being approximately 17.3mm x 13mm.
Mirrorless system lens meaning full#
The point here is that an APS-C sensor is smaller than a full frame sensor. APS-CĪPS-C is Advanced Photo System I will not go into that in this post. This is the exact size that 35mm film negatives are and were back in the days before digital. Full frameįull frame refers to cameras which have a sensor that is 36mm wide x 24mm high. This is about the main camera systems though. There are others such as medium format and large format, as well of course as sensors in smart phones. There are here are three principal sensor sizes. Now I know that this is a huge over simplification, but I hope you get the point. Think of the sensor as doing the same job that film did. The sensor is the bit that records the photo. Bear with me, I am nearly at micro four thirds! What does the sensor do? These different formats relate to the size of the sensor. You can, in theory, get mirrorless cameras in all these formats, but only find DSLRS in APS-C and full frame formats. Simple! 3 – What other types of camera are there?ĭSLRs and mirrorless can be further sub-divided into three further categories A mirrorless camera does not have the mirror that DSLRs do. Whilst some terms in photography are confusing, mirrorless is a good term. This is an evolution of film cameras, SLRs. This allows the user to look, via the mirror, through the lens at the scene being photographed.
DSLR camerasĭigital Single Lens Reflex cameras have a mirror on top of the camera. There are others out there, but these are the two main groups. There is no mirror but instead an EVF, and the cameras have smaller sensors. The sensor in micro four thirds cameras is smaller than in APS-C and full frame cameras – more on that below.īasically, micro four thirds cameras are smaller than other systems, but designed from the ground up in the digital age. Once you have removed the optical viewfinder you need to replace this with something else or rely solely on the screen on the back of the camera, which is not a good idea. Remove the mirror box though and you need something else to be able to view images. Remove the mirror box and you have a mirrorless camera! The mirror box allows you to look via the viewfinder through the lens on a DSLR. Micro four thirds is the evolution of four thirds, but without the mirror box. And that is something I am struggling to get my head around!įour thirds was created in the digital age, DSLRs are an evolution of film cameras called SLRs. This system included both DSLR and mirrorless camera bodies with a universal lens mount – you could put anyone’s lens on anyone’s body. So micro four thirds has some big names involved, Olympus, Panasonic and Kodak. Micro four thirds is the evolution of the four thirds system which was created by Olympus and Kodak in 2008. The micro four thirds camera system was released by Olympus and Panasonic in 2008.
If anything in here does not make sense drop me a line and I will try to explain. The first part of this post is a bit technical, but I need to go through this stuff to explain micro four thirds properly. Yes, travel photography has a lot to answer for and is the main reason I am looking into micro four thirds photography. And this is very relevant to micro four thirds photography. I also photograph buildings and their surrounding environments in other places on this wonderful planet of yours. It should come as no surprise to you that I therefore specialise in photographing buildings. I am based in the south of England in the lovely county of Dorset. I am a professionally qualified photographer and also a professionally qualified construction manager.
