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 suitable?
That’s what this text is all about.
I’m going to elucidate whether or not you should use a
full body lens on an APS-C physique. I’m going to elucidate whether or not you should use an
APS-C lens on a full-frame physique.
And also you’ll come away figuring out 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 in case you 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 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 Subject (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 digicam you mount it on.
Nonetheless, there may be one characteristic that adjustments
with an APS-C sensor dimension:
Lens’s Subject 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. However the digicam sensor doesn’t all the time use this complete projected picture. A full-frame lens is designed to venture a picture that’s excellent in dimension for a full body digicam sensor.
However 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?
Benefits of Utilizing Full-Body
Lens on APS-C Digital camera
Now that you understand how a full-frame lens works
on an APS-C digicam, you may see that there’s one massive 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.

(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 must seize photographs of topics far off within the distance. It will increase their lens’s attain, though the focal size doesn’t change.
Disadvantages of Utilizing Full-Body
Lens on APS-C Digital camera
There are a number of necessary disadvantages to
utilizing this mixture.
See additionally: Prime Rated Lenses for Fowl Images
For one, full body lenses are typically 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 so much tougher, as a result of it nixes the ultra-wide discipline of view. That’s one of many the reason why many panorama photographers want to shoot full-frame, particularly if their fashion includes creating ultra-wide, sweeping panorama pictures.
What Occurs When You Connect an
APS-C Lens on a Full-Body Digital 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 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 Subject (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 concern 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, in case you’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 wreck a picture–except you crop it out.
In the event 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 can be a viable manner of taking pictures,
however you’re going to lose some decision. In any case, the digicam is cropping out
megapixels!
Canon EF-S Lenses Situation
Notice that issues get a bit trickier in the case of native Canon lenses. In the event 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.
Benefits of Utilizing an APS-C Lens
on a Full-Body Digital camera
Right here’s the principle benefit of mounting APS-C
lenses on full-frame cameras:
You’ll be able to make the most of smaller, cheaper
APS-C lenses supplied by producers. These are sometimes high-quality, however they
value 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 affords glorious
high quality and a compact construct for an impressively low value.
Disadvantages of Utilizing an APS-C
Lens on a Full-Body Digital camera
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 just’ve completed this text, you
know all about utilizing APS-C lenses on full-frame sensors, as nicely full-frame
lenses on APS-C sensors.
And you already know the professionals and cons of every possibility.
Simply keep in mind:
You don’t must be afraid of mounting full-frame
lenses on APS-C cameras, nor do you want to be afraid of the reverse.
(Until you’re utilizing a Canon EF-S lens on a
full-frame digicam–which it’s best to by no means do!)
