Micro 4 3 Or Aps C

by -50 views

If you don’t have fourth dimension to read this article in full, then the bones differences betwixt micro 4/iii vs APS C cameras is that micro 4 thirds offers a lighter camera more suitable for travel and for daily utilize, while APS-C cameras are better where image quality and the use of extreme wide-angle lenses is necessary.

When looking at the smaller camera formats, both micro 4/iii (also known as MFT or micro four thirds) and APS-C cameras appear among the well-nigh popular models on offer, merely what is the difference between them?

This commodity covers the pros and cons of MFT vs APS C, along with descriptions and examples of each, so that you can be sure which of these more portable formats is right for you and your photography.


What is a Micro 4/3 vs APS C Sensor?

When y’all meet micro four 3 or APS C in a photographic camera clarification, this refers to the size of the sensor. Sensor size has a number of knock-on furnishings to how a camera behaves and handles, which are covered beneath.

In full general, a larger sensor size is better for image quality, but at the expense of portability and price.

Micro 4/3 Sensor

The starting time micro 4/3 cameras were just released in 2008, from a standard developed past Olympus and Panasonic for their iterations of mirrorless cameras.

The micro four thirds sensor size is 17.three mm wide × 13.0 mm high (21.6 mm on the diagonal), which is comparable to the 110 cartridge picture developed by Kodak.

A micro 4/3 sensor gets its proper noun because this width and height is in the iv:3 attribute ratio, which is the standard medium format ratio. Standard DSLRs and cameras that use 35mm picture show have a three:2 aspect ratio, and then comparing the micro four thirds vs APS C cameras, the micro four thirds cameras are ameliorate suited for making prints at standard medium format sizes like half-dozen x four.5 inches.

You might have heard of the four thirds arrangement (without the micro in front), which is an older system from Olympus, originally designed for DSLRs.

This 4/3 system needed space for the reflex mirror of the DSLR, which is not present in mirrorless cameras.

Therefore, comparing micro iv/three vs 4/3, the sensor size is the same, simply there is no longer any space left between the lens mount and the sensor for this mirror or pentaprism, meaning that cameras using micro 4/iii can be fabricated much smaller and can fit a much wider range of lenses, fifty-fifty from third-party manufacturers with the necessary adapters.

APSC Sensor Size

The APS-C sensor is from an older system, originally designed for film cameras and which has at present been repurposed for digital use, peculiarly for DLSRs, only also for some mirrorless cameras.

The APSC sensor size is 25.1 mm wide × 16.7 mm loftier
in virtually cases, giving it a 3:2 attribute ratio to friction match standard 35 mm film, and making it most suitable for standard print sizes for picture, like 6 ten 4 inches.

Canon brand slightly smaller APS-C sensors, at 22.3 mm wide ten xiv.ix mm high, but this maintains the 3:ii aspect ratio.

Both of these sizes are smaller still than the original APS-C film that was produced from 1996 by Kodak, and significantly smaller than 35 mm film, only comparing APS C vs micro four thirds, the APS-C size is 86% larger than an MFT sensor.

APS-C and Micro iv/3 Size Comparison

You tin directly compare the existent sensor sizes of APS-C and MFT sensors in the prototype below, with a full frame, 35mm sensor size as comparison.

You lot can see that micro four thirds sensors are significantly smaller than APS-C, and you can see their different aspect ratio. The implications of this are discussed beneath.

Field of View & Crop Factor Comparisons

The main consequence of the different sensor sizes seen above is seen in their relative fields of view, otherwise known as a crop factor.

Yous almost probably already know that the shorter the focal length, the wider the field of view. This is why brusk lenses, such as those with a focal length of 24mm, are also referred to every bit broad bending lenses.

Simply, the bodily field of view that you run across through the lens is dependent on the sensor size.

This is because a standard lens casts a circle of lite onto the image sensor, which is then recorded to make your image, but a smaller sensor can merely use the most central part of this circle of light.

This has the same effect as zooming in, and means that smaller sensors accept a smaller field of view with the same lens. Y’all can see an instance of this in the paradigm below.

APS C vs Micro Four Thirds Crop Factors and Fields of View
Comparing of field of view for APS-C vs Micro Four Thirds, if the lensman keeps the aforementioned focal length and is in the same position.

This reduced field of view with smaller sensors is most ordinarily referred to equally a crop factor. This is displayed equally a number that shows how much you must multiply the full frame focal length by in society to arrive at the credible focal length for your smaller sensor.

The crop factors for the APS-C and MFT cameras are:

  • Full Frame = ane
  • Nikon, Pentax & Sony
    APS-C = 1.5
  • Canon APS-C = 1.6
  • Micro Four Thirds (Panasonic & Olympus) = ii

Then, a 24mm lens used on a total frame photographic camera would have an apparent focal length of 24mm, equally expected as this is the reference to which we compare other sensor sizes.

The aforementioned 24mm lens used on a Nikon APS-C photographic camera would have an credible focal length of 24 ten i.5 = 36mm.

And on the Catechism APS-C photographic camera, the 24mm lens would accept an apparent focal length of 24 x one.half dozen = 38.4mm.

Finally, the an Olympus Micro Four Thirds camera using the 24mm lens would have an apparent focal length of 24 x 2 = 48mm.

Depth of Field

Although depth of field is not a primary concern for well-nigh photographers, information technology is useful to know that in general, smaller sensors result in a larger depth of field.

This means that the surface area that is ‘in focus’ is increased with a smaller sensor for the same focal length and aperture,
where the subject is in the same position in the frame.

This is considering in lodge to become the subject to fill the frame in the aforementioned way, you will have to move farther away with a camera with a smaller sensor, which increases the depth of field. This is directly connected to the crop cistron seen above.

Of course, y’all can always open up up the aperture to subtract depth of field, and so this isn’t a big issue in practise, just might aid sway your decision if you are a portrait photographer.

Resolution & Pixel Size

Micro 4/3 camera

Resolution of a camera is measured in pixels, with each of the pixels seen in your photograph file corresponding to a concrete pixel on the sensor.

Pixel size is not fixed, with some models of camera having larger or smaller pixels even within the aforementioned camera format due to differing resolutions, only in general, APS-C cameras tend to accept smaller pixels in their most recent models, due to sensor innovation.

For example, the Canon M6 Marker Two, an APS-C camera, has a pixel size of 3.20µm from a 32.5 megapixel resolution, while the Olympus OM-D Due east-M1, a micro four/3 camera, has a pixel size of 3.72µm from a xvi.3 megapixel resolution.

Just why does this matter?

Simply put, the larger the resolution, the better the prototype detail a camera can record, just this also applies to pixel size.

That means that the larger the individual pixels on a sensor, the better for low calorie-free performance, for reducing noise and for increased dynamic range.

Then ideally you desire a photographic camera with both a large resolution and a large pixel size.

In general, a physically larger sensor volition have larger pixels for the same resolution, meaning APS-C sensors are amend for paradigm quality. They also tend to offering higher resolutions due to their increased size.

Overall Size & Portability

APS-C camera

If yous are looking for a camera for travel, then information technology pays to go for something both pocket-size and portable. There’s zippo worse than leaving your large, heavy camera at home and missing a photo, when you could hands have taken a small, pocket sized camera, albeit one with slightly worse prototype quality, that would take got you that motion-picture show.

In near cases,
a larger sensor such as that on APS-C cameras, means that the camera itself will be both larger and heavier.

If you lot are concerned at all about portability, and so micro 4/3 is the way to go, or you could go for even smaller sensor sizes for a truly portable photographic camera, with something like a 1/2.3″ sensor. Cameras in this bracket are covered in my article on the all-time cameras under $300.

Lens Compatibility

Non only does a larger sensor hateful a larger camera body, it too often means larger lenses.

Micro iv/iii cameras not simply benefit from smaller lenses than APS-C cameras, but because of the specific compages of the lens mount, information technology is possible to apply many brands of lenses outside of the standard Olympus and Panasonic lenses, with the appropriate adapter.

This is particularly useful if y’all intend to look for cheaper, used lenses from older camera systems, equally it can really reduce the overall toll of your camera organisation.

APS-C cameras can of course use lenses exterior of their own system, but you are much more limited with your choice.

Micro Four Thirds vs APS C: Pros & Cons

Micro Four Thirds vs APS C

So after roofing all of the chief differences betwixt micro iv thirds vs APS-C cameras, what are the overall pros and cons of each, and in what state of affairs would you want either?

Micro 4/3 Pros:

  • 4:iii aspect ratio is improve suited for press photos at standard medium format sizes, similar 6×4.five inches.
  • You tin can use a broad range of third-political party lenses from the past and present with appropriate adapters, comprising hundreds of lenses, many for cameras no longer in production and available for a very low cost.
  • Lenses tin be much smaller and shorter for the same apparent focal length, also reducing their cost.
  • Camera bodies tend to be much lighter and more portable.
  • The smaller sensor generates less oestrus, which can help reduce noise in long exposures.
  • Increased depth of field means that you are better placed for landscape photography, particularly without a tripod.

Micro 4/3 Cons:

  • Smaller sensor size means that image quality doesn’t quite friction match APS-C in most cases.
  • Large 2x crop gene means that it is difficult to get ultra-broad angle lenses.
  • There are no models with optical viewfinders – merely electronic viewfinders.
  • But two real manufacturers of camera bodies in Olympus and Panasonic, pregnant not many use cases are catered for.

APS-C Pros:

  • three:2 aspect ratio is amend suited for printing photos at standard 35mm photo sizes, like 6×4 inches.
  • Larger sensor size ways better image quality, often coupled with larger pixels.
  • Less noise and more dynamic range in general, although micro iv thirds cameras might beat this in long exposure images.
  • Both mirrorless and traditional DSLR models are bachelor with this sensor size, meaning there are many more than possible use cases.
  • Smaller depth of field is improve suited to wedding and portrait photographers.
  • A very popular sensor size that doesn’t look similar it will be discontinued whatever time soon.
  • Easier to get an farthermost wide-angle lens.

APS-C Cons:

  • You don’t have the same broad range of older lenses available every bit for MFT cameras.
  • Larger lenses and photographic camera bodies makes these models less portable and more expensive.
  • Many would be better off either choosing a full frame camera or M43, as some of these models are a bit stuck on the fence in terms of what they want to exercise.

I hope that this has helped make the differences and similarities between micro iv thirds and APS C cameras clear in your minds. Either of them are excellent choices for most photographers,
with micro 4/three ultimately better if you volition be travelling or using your camera away from home for long periods of time, and APS-C better for situations where image quality is key.

Only you don’t only take to consider APS-C or M43 cameras, at that place are also full frame models bachelor. Comparing full frame vs micro 4/3 for landscape photography, there is no contest in full frame cameras offering improve image quality and better overall operation. Take a look at some of my photos, all taken with a full frame camera for proof!
