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 numerous digicam/lens mixtures are appropriate?
That’s what this text is all about.
I’m going to elucidate whether or not you should utilize a
full body lens on an APS-C physique. I’m going to elucidate whether or not you should utilize an
APS-C lens on a full-frame physique.
And also you’ll come away realizing all about your
digicam 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 if you happen to take that full-frame lens…
…and mount it onto an APS-C digicam physique?
In reality, 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 gap from some extent contained in the lens to the digicam sensor, and this isn’t modified by a smaller, APS-C sensor.
Depth of Subject (DoF)
Second, the depth of area doesn’t change. The
depth of area 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 digicam you mount it on.
Nonetheless, there’s one function that modifications
with an APS-C sensor dimension:
Lens’s Subject of View
You see, everytime you mount a lens onto a
digicam, the lens initiatives a round picture onto the digicam sensor.
(This is named the circle of projection.)
That round picture is all the time the identical dimension, irrespective of the digicam sensor. However the digicam sensor doesn’t all the time use this complete projected picture. A full-frame lens is designed to challenge a picture that’s good in dimension for a full body digicam sensor.
However when a full-frame lens is mounted onto a
crop-sensor digicam, the smaller sensor primarily crops the picture projected by
the full-frame lens. And you find yourself with a narrower area 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 know the way a full-frame lens works
on an APS-C digicam, you may see that there’s one huge benefit to utilizing this
mixture:
The narrower area of view will increase lens attain, so that you’re capable of {photograph} extra distant topics with ease. This elevated area of view is sometimes called a crop issue, the place a 100mm lens is cropped to a 150mm lens on an APS-C digicam.

(Regardless of this technique of referring to APS-C
cameras, the focal size doesn’t really change! Solely the sector of view is
affected.)
That is necessary for wildlife and sports activities photographers as a result of they typically have to seize pictures of topics far off within the distance. It will increase their lens’s attain, despite the fact that the focal size doesn’t change.
Disadvantages of Utilizing Full-Body
Lens on APS-C Digicam
There are just a few necessary disadvantages to
utilizing this mixture.
See additionally: High Rated Lenses for Fowl Images
For one, full body lenses are usually larger 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 images rather a lot tougher, as a result of it nixes the ultra-wide area of view. That’s one of many the explanation why many panorama photographers favor to shoot full-frame, particularly if their type includes creating ultra-wide, sweeping panorama photographs.
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 digicam is rather like attaching a full-frame lens to an APS-C digicam.
Focal Size
For example, 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 Subject (DoF)
And the lens’s depth of area 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 may be one problem with mounting an APS-C lens
on a full-frame digicam, nonetheless:
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 the whole full-frame sensor.
Now, if you happen to’re utilizing Sony or Nikon cameras and
lenses, then you may nonetheless mount an APS-C lens onto a full-frame digicam. However
you’ll typically see vignetting (i.e., darkening) across the edges of the body,
which might simply damage a picture–except you crop it out.
For those who mount an APS-C lens on a full-frame
Nikon and Sony digicam and also you don’t see vignetting, that is most likely 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 can be a viable means of taking photographs,
however you’re going to lose some decision. In spite of everything, the digicam is cropping out
megapixels!
Canon EF-S Lenses Difficulty
Observe 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 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.
Benefits of Utilizing an APS-C Lens
on a Full-Body Digicam
Right here’s the primary benefit of mounting APS-C
lenses on full-frame cameras:
You’ll be able to benefit from smaller, cheaper
APS-C lenses provided by producers. These are sometimes high-quality, however they
value a lot lower than their full-frame equivalents.
For example, Nikon customers typically mount the
(APS-C mount) 35mm f/1.8 lens on full-frame our bodies. This lens affords 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
digicam, 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 digicam will
crop for you–so {that a} 24 megapixel sensor produces a ten megapixel picture.
Conclusion
Now that you simply’ve completed this text, you
know all about utilizing APS-C lenses on full-frame sensors, as effectively full-frame
lenses on APS-C sensors.
And you understand the professionals and cons of every possibility.
Simply bear in mind:
You don’t should be afraid of mounting full-frame
lenses on APS-C cameras, nor do it’s essential be afraid of the reverse.
(Except you’re utilizing a Canon EF-S lens on a
full-frame digicam–which you must by no means do!)
