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 digicam/lens combos 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 you’ll come away understanding all about your
digicam and lens compatibility.
Sound good?
Let’s get began.
What Happens When You Attach a
Full Frame Lens on APS-C Cameras?
A full-frame lens is designed for full-frame
cameras. But what occurs should you take that full-frame lens…
…and mount it onto an APS-C digicam physique?
In reality, not a lot in any respect.
Focal Length
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 digicam sensor, and this isn’t modified by a smaller, APS-C sensor.
Depth of Field (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.
Image Quality
Third, the standard of the lens stays the identical. The optics of the lens stay fixed it doesn’t matter what digicam you mount it on.
However, there may be one function that modifications
with an APS-C sensor dimension:
Lens’s Field of View
You see, everytime you mount a lens onto a
digicam, the lens tasks a round picture onto the digicam sensor.
(This is called the circle of projection.)
That round picture is all the time the identical dimension, regardless of the digicam sensor. But the digicam sensor doesn’t all the time use this whole projected picture. A full-frame lens is designed to mission a picture that’s excellent in dimension for a full body digicam sensor.
But when a full-frame lens is mounted onto a
crop-sensor digicam, 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?
Advantages of Using Full-Frame
Lens on APS-C Camera
Now that you understand how a full-frame lens works
on an APS-C digicam, 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 in a position to {photograph} extra distant topics with ease. This elevated discipline of view is also known as a crop issue, the place a 100mm lens is cropped to a 150mm lens on an APS-C digicam.

(Despite this methodology of referring to APS-C
cameras, the focal size doesn’t really change! Only the sector of view is
affected.)
This is vital for wildlife and sports activities photographers as a result of they typically have to seize photos of topics far off within the distance. It will increase their lens’s attain, though the focal size doesn’t change.
Disadvantages of Using Full-Frame
Lens on APS-C Camera
There are a number of vital disadvantages to
utilizing this mix.

For one, full body lenses are usually greater and costlier than their APS-C counterparts.
Plus, whereas the additional attain is beneficial for sports activities and wildlife photographers, it makes wide-angle panorama pictures loads more durable, as a result of it nixes the ultra-wide discipline of view. That’s one of many the reason why many panorama photographers desire to shoot full-frame, particularly if their model entails creating ultra-wide, sweeping panorama photographs.
What Happens When You Attach an
APS-C Lens on a Full-Frame Camera?
In some ways, attaching an APS-C lens on a full body digicam is rather like attaching a full-frame lens to an APS-C digicam.
Focal Length
For occasion, the lens focal size doesn’t change – as a result of identical 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, fully unaffected by the sensor dimension.
Depth of Field (DoF)
And the lens’s depth of discipline doesn’t change,
both, as a result of the focal size of the lens stays fixed.
Image 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 is one challenge with mounting an APS-C lens
on a full-frame digicam, nevertheless:
Image 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, should 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 digicam. But
you’ll typically see vignetting (i.e., darkening) across the edges of the body,
which might simply wreck a picture–except you crop it out.
If you mount an APS-C lens on a full-frame
Nikon and Sony digicam and also you don’t see vignetting, that is in all probability as a result of
the digicam routinely recognized the lens as APS-C and switched right into a crop
mode that makes use of solely a part of the sensor. This is a viable method of taking photographs,
however you’re going to lose some decision. After all, the digicam is cropping out
megapixels!
Canon EF-S Lenses Issue
Note that issues get a bit trickier relating to native Canon lenses. If you mount a Canon APS-C lens (labeled as an EF-S lens) onto a Canon full-frame digicam, the lens mount will ram into the mechanism contained in the digicam, which you wish to keep away from in any respect prices. This gained’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.
Advantages of Using an APS-C Lens
on a Full-Frame Camera
Here’s the principle benefit of mounting APS-C
lenses on full-frame cameras:
You can benefit from smaller, cheaper
APS-C lenses supplied by producers. These are sometimes high-quality, however they
value a lot lower than their full-frame equivalents.
For occasion, 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 value.
Disadvantages of Using an APS-C
Lens on a Full-Frame Camera
When you utilize an APS-C lens with a full-frame
digicam, you’re solely utilizing a part of the sensor. This, in flip, reduces the
decision of the ultimate picture. You’ll be pressured to crop, or your digicam 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 already know the professionals and cons of every possibility.
Just bear in mind:
You don’t must be afraid of mounting full-frame
lenses on APS-C cameras, nor do that you must be afraid of the reverse.
(Unless you’re utilizing a Canon EF-S lens on a
full-frame digicam–which it is best to by no means do!)
