Do you wish to know the distinction between a full body lens on APS-C vs APS-C lens on full body? Do you wish to know which lenses can mount on which cameras and whether or not varied digital camera/lens mixtures are appropriate?
That’s what this text is all about.
I’m going to clarify whether or not you need to use a
full body lens on an APS-C physique. I’m going to clarify whether or not you need to use an
APS-C lens on a full-frame physique.
And also you’ll come away understanding all about your
digital camera and lens compatibility.
Sound good?
Let’s get began.
What Occurs When You Connect a
Full Body Lens on APS-C Cameras?
A full-frame lens is designed for full-frame
cameras. However what occurs in the event you take that full-frame lens…
…and mount it onto an APS-C digital camera physique?
In fact, not a lot in any respect.
Focal Size
First, the focal size of the lens doesn’t change. You see, the focal size of the lens is a bodily property – it’s already mounted from the second the lens is created. Focal size is the space from some extent contained in the lens to the digital camera sensor, and this isn’t modified by a smaller, APS-C sensor.
Depth of Area (DoF)
Second, the depth of discipline doesn’t change. The
depth of discipline is decided by the aperture, the focal size, and the
distance from the lens to the purpose of focus; none of those are altered by an
APS-C sensor.
Picture High quality
Third, the standard of the lens stays the identical. The optics of the lens stay fixed it doesn’t matter what digital camera you mount it on.
Nonetheless, there’s one characteristic that adjustments
with an APS-C sensor dimension:
Lens’s Area of View
You see, everytime you mount a lens onto a
digital camera, the lens tasks a round picture onto the digital camera sensor.
(This is called the circle of projection.)
That round picture is all the time the identical dimension, regardless of the digital camera sensor. However the digital camera sensor doesn’t all the time use this complete projected picture. A full-frame lens is designed to challenge a picture that’s excellent in dimension for a full body digital camera sensor.
However when a full-frame lens is mounted onto a
crop-sensor digital camera, the smaller sensor basically crops the picture projected by
the full-frame lens. And you find yourself with a narrower discipline of view–that’s, you
find yourself with a narrower portion of the scene captured by the sensor.
Make sense?
Benefits of Utilizing Full-Body
Lens on APS-C Digicam
Now that you understand how a full-frame lens works
on an APS-C digital camera, you’ll be able to see that there’s one large benefit to utilizing this
mixture:
The narrower discipline of view will increase lens attain, so that you’re capable of {photograph} extra distant topics with ease. This elevated discipline of view is sometimes called a crop issue, the place a 100mm lens is cropped to a 150mm lens on an APS-C digital camera.

(Regardless of this technique of referring to APS-C
cameras, the focal size doesn’t really change! Solely the sphere of view is
affected.)
That is vital for wildlife and sports activities photographers as a result of they typically must seize pictures of topics far off within the distance. It will increase their lens’s attain, although the focal size doesn’t change.
Disadvantages of Utilizing Full-Body
Lens on APS-C Digicam
There are a couple of vital disadvantages to
utilizing this mixture.

For one, full body lenses are usually larger and dearer than their APS-C counterparts.
Plus, whereas the additional attain is beneficial for sports activities and wildlife photographers, it makes wide-angle panorama pictures quite a bit more durable, as a result of it nixes the ultra-wide discipline of view. That’s one of many the explanation why many panorama photographers favor to shoot full-frame, particularly if their type entails creating ultra-wide, sweeping panorama pictures.
What Occurs When You Connect an
APS-C Lens on a Full-Body Digicam?
In some ways, attaching an APS-C lens on a full body digital camera is rather like attaching a full-frame lens to an APS-C digital camera.
Focal Size
As an illustration, the lens focal size doesn’t change – as a result of similar to a full-frame lens, the APS-C lens’s focal size is mounted from the second it’s produced. Focal size is an optical property of the lens, utterly unaffected by the sensor dimension.
Depth of Area (DoF)
And the lens’s depth of discipline doesn’t change,
both, as a result of the focal size of the lens stays fixed.
Picture High quality
Even the standard of the lens doesn’t change;
as I defined above, a lens’s picture high quality isn’t influenced by the sensor
dimension.
There’s one situation with mounting an APS-C lens
on a full-frame digital camera, nevertheless:
Picture Projection
The picture that’s projected by the lens is designed for APS-C sensors, not full-frame sensors. So it’s smaller than required and doesn’t cowl all the full-frame sensor.
Now, in the event you’re utilizing Sony or Nikon cameras and
lenses, then you’ll be able to nonetheless mount an APS-C lens onto a full-frame digital camera. However
you’ll typically see vignetting (i.e., darkening) across the edges of the body,
which might simply wreck a picture–until you crop it out.
For those who mount an APS-C lens on a full-frame
Nikon and Sony digital camera and also you don’t see vignetting, that is in all probability as a result of
the digital camera mechanically recognized the lens as APS-C and switched right into a crop
mode that makes use of solely a part of the sensor. It is a viable means of taking pictures,
however you’re going to lose some decision. In spite of everything, the digital camera is cropping out
megapixels!
Canon EF-S Lenses Challenge
Word that issues get a bit trickier in the case of native Canon lenses. For those who mount a Canon APS-C lens (labeled as an EF-S lens) onto a Canon full-frame digital camera, the lens mount will ram into the mechanism contained in the digital camera, which you wish to keep away from in any respect prices. This received’t be an issue with third-party lenses for Canon APS-C cameras, however native EF-S lenses merely shouldn’t be mounted on Canon full-frame cameras.
Benefits of Utilizing an APS-C Lens
on a Full-Body Digicam
Right here’s the principle benefit of mounting APS-C
lenses on full-frame cameras:
You’ll be able to reap the benefits of smaller, cheaper
APS-C lenses provided by producers. These are sometimes high-quality, however they
price a lot lower than their full-frame equivalents.
As an illustration, Nikon customers typically mount the
(APS-C mount) 35mm f/1.8 lens on full-frame our bodies. This lens gives glorious
high quality and a compact construct for an impressively low worth.
Disadvantages of Utilizing an APS-C
Lens on a Full-Body Digicam
Once you use an APS-C lens with a full-frame
digital camera, you’re solely utilizing a part of the sensor. This, in flip, reduces the
decision of the ultimate picture. You’ll be compelled to crop, or your digital camera will
crop for you–so {that a} 24 megapixel sensor produces a ten megapixel picture.
Conclusion
Now that you just’ve completed this text, you
know all about utilizing APS-C lenses on full-frame sensors, as properly full-frame
lenses on APS-C sensors.
And you realize the professionals and cons of every choice.
Simply keep in mind:
You don’t have to be afraid of mounting full-frame
lenses on APS-C cameras, nor do it is advisable be afraid of the reverse.
(Until you’re utilizing a Canon EF-S lens on a
full-frame digital camera–which it’s best to by no means do!)
