Full Frame Lens On Aps C

At that place is an ongoing discussion within the photography world on the pros, cons and when exactly it is best to use APS-C lenses rather than total frame lenses. When you come to choose a new lens for your camera, deciding between an APS-C or total frame lens can accept a significant effect on the images you produce.

Understanding the differences between the 2 types of lenses will help you choose the correct one for you and your photography type.

While total frame cameras are most often used past professional photographers and are known for their high-quality images, APS-C lenses are not to be sniffed at. The smaller sensor plant in APS-C camera bodies means that the camera and the lenses are able to exist smaller, more compact, and lighter- a bonus for styles of photography such as street, travel, and wedding.

Nevertheless, understanding the differences between the two types of lenses as well every bit being able to tackle the “crop factor” calculations will really help to set you apart from most coincidental, amateur photographers. As with most art forms, one time y’all know the rules well enough, you can larn how to bend them to produce something unique. And while I’ll leave beingness unique up to yous, today I’m going to help you understand more of the rules.

What’s the Difference Between APS-C and Full frame?

APS-C and total frame refers to the photographic camera’due south sensor size. Information technology has nothing to practice with how many pixels are on the sensor though. Like most things to do with photography the terms date back to when cameras used picture show rather than the digital sensors that the majority of today’s cameras utilize.

  • A full frame photographic camera uses a sensor that is the same size every bit the traditional 35mm motion picture. It measures 36 10 24mm.
  • An APS-C sensor which is institute in the majority of DSLRs and mirrorless cameras is slightly smaller. Information technology measures 22 x 15mm.

APS-C stands for avant-garde photo system type C. It is a type of image sensor format that commencement appeared in 1996 and actually has three variations, “H”, “C”, and “P”. Where H stands for high definition, C for classic and P for panorama. While APS-C is the virtually common type all three use a smaller sensor size than the full frame sensor.

Practice Professional Photographers Use APS-C?

The traditional narrative is that professional photographers use professional equipment i.e., full frame cameras and lenses. While this may exist truthful for the best photographers in the world there are also many professional person photographers who are choosing to use either APS-C camera bodies and/or lenses.

Every bit engineering science has progressed, so too has the quality of the APS-C lenses and cameras allowing photographers to create high quality images no matter whether they use total frame cameras and lenses or not. Most notably this is seen in situations where having lighter, smaller equipment is favorable such equally event, street, and travel photography.

Are APS-C Lenses Cropped?

As presently as nosotros outset talking most APS-C and total frame cameras and lenses the “cropped” starts actualization. Information technology can exist a specially confusing concept to get your head around at showtime (it certainly took me a piddling while), especially when we start needing to do calculations. Don’t worry though, I’ve got a petty hack for you further down.

Firstly though, it’southward of import to empathise that when we talk virtually cropping and the crop factor, we aren’t talking about the lenses specifically. Aye, the lenses exercise come into the play but once more we are talking almost the image sensor size.

If yous take a look at your camera and its lens(es) you will notice that the lens is circular, and the sensor is rectangular. This means that the round lens creates a round epitome, and the rectangular image sensor captures a rectangular portion of the round image. Brand sense?

As the standard, total frame sensor is 35mm, a camera with an image sensor that is smaller than this (i.east., the APS-C epitome sensor) will cover a smaller portion of the aforementioned circular prototype created past the same lens. This changes the field of view and is responsible for the term ingather.


While the depth of field is not affected, it does appear zoomed in or like information technology has been cropped when you compare it to an prototype taken using a full frame sensor with the same aperture.

APS-C to Total frame Calculator

Before digital photography took over the photography world, pretty much all cameras worked with 35mm film and things were great. However as digital cameras became more and more popular, photographers got a petty bit stuck.

This was because the majority of digital cameras used a smaller sensor size than the traditional 35mm pic cameras. So as photographers made the switch to digital photography, they noticed that the field of view seen through the lens of a digital camera was different to that of a 35mm film camera. No longer was a 50mm lens giving them a 50mm lens field of view. Instead, it was simply a footling scrap more zoomed in.

To go over this, photographers created what is known as the crop factor. A simple calculation that allows y’all figure out “35mm equivalent” field of view for each lens when yous attach information technology to a camera with a smaller sensor size.

Most APS-C cameras have a ingather factor between 1.3 and ane.8 and are easy to calculate with a quick internet search and without having to do a bunch of math. Then all y’all need to do is multiply past the focal length.

For case, a 50mm lens on an APS-C photographic camera with a crop factor of 1.5 -you would do 1.5 x l which would give you 75. Meaning that your 50mm lens would be showing y’all the aforementioned view that a 75mm lens would on a 35mm image sensor.

For those that have a zoom lens you can also work out the equivalent focal length in the same way. So, a 70-200mm zoom lens being used on a i.5x APS-C sensor would requite you a field of view that is equivalent to 105-300mm on a full frame sensor.

Total frame Lens On APS-C Photographic camera

A full frame lens has patently been made to be used with a full frame camera, only can you still use it on your APS-C photographic camera? Most likely yes. While I would always recommend checking with the make and model to encounter if they are compatible, this combination of lens and camera body is a common option for photographers just starting out.

The full frame lens on an APS-C camera doesn’t change the depth of field or the paradigm quality equally these are primarily adamant past the lens itself. The only major affair that changes (as I discussed before) is the field of view.

When a full frame lens is used with an APS-C sensor the field of view is narrowed. This means that you can photograph subjects that are farther away with greater ease. An of import thing to consider if wild fauna and sports photography is your matter.


Information technology is of import to have into consideration that these total frame lenses tend to be bigger, heavier, and more expensive than APS-C lenses. So it may non be ideal if you are stuck for space and weight such every bit when you are traveling.  Plus, if you lot’re a mural photographer, this combination of lens and body won’t allow you to capture ultra-wide-angle shots and the smaller nature of the APS-C sensor will ingather some of the epitome off.

APS-C Lenses on Full Frame Camera

So, if using a full frame lens on an APS-C torso results in a zoomed in prototype, it stands to reason that the opposite combination, an APS-C lens on a full frame body would result in a zoomed-out image. That is to say yous end up with some heavy vignetting around the outside of the image. There are, still, some total frame cameras that are able to either detect the APS-C lens automatically or allow you to change the settings manually in order to ingather the image so that you don’t run into the vignetting and the image fills the frame.

Nikon, Sony, and Pentax cameras all permit yous to pair an APS-C lens with a full frame trunk. Canon, on the other hand has a slightly different mount that doesn’t allow you to use a Catechism APS-C lens on a Catechism full frame trunk. Interestingly some 3rd
political party APS-C lens are nevertheless compatible with the Canon total frame body.


The biggest advantage to using an APS-C lens with a full frame camera is that APS-C lenses tend to be less expensive simply notwithstanding high quality. They tin also piece of work well if you are using your camera to capture video content likewise.


Using an APS-C lens on a full frame camera ways that you volition only use office of the sensor when taking your photo. This in effect reduces your image resolution and tin can mean that a camera with 24 megapixels may be restricted to producing x-megapixel images.

Here’s Wolf Amri’due south take on the APS-C vs total frame discussion:

Converting Your APS-C Lens to Full Frame Using a Teleconverter

As we discussed before, if you utilise a full frame camera body with an APS-C lens y’all are probable to be greeted with a whole lot of vignetting. However, investing in full frame lenses or an APS-C camera body may not be possible. Luckily, there is a way to convert your APS-C lens into a full frame lens without having to just buy a full frame version of it. Yous use a teleconverter (also known equally an extender).

A teleconverter is a little gadget the fits between your camera body and lens. It works past magnifying whatsoever is in the center of the other lens and so helps to bridge the gap between the APS-C and full frame sensor size. Teleconverters are available in different sizes simply it is of import to check your photographic camera make and model and not all cameras are compatible with all teleconverters.

Teleconverters are a great friend to those who are short of space and weight. A 2x teleconverter tin transform your 100-400mm zoom lens into an 800mm lens without the hefty weight and size increase. Awesome if y’all’re into travel, street, or event photography. In fact, teleconverters are becoming more and more common within sports photography were getting shut to the action can sometimes be hard but you still demand the close-up shots.

These little additions won’t break the banking concern either which is cracking if you lot’re looking for a fashion to convert your APS-C lens to full frame. Cull a teleconverter with the aforementioned crop cistron equally your camera and say goodbye to your vignetting.


Unfortunately, teleconverters not just magnify the image, but they can also magnify any chromatic aberrations and other unwanted features that a dedicated lens wouldn’t give yous.

The biggest downside to teleconverters, however, is that they result in a reduction in lite and then a reduction in the widest discontinuity available to you. This might besides lead to slower autofocus and increased photographic camera milk shake. So, if you are planning to shoot in low calorie-free atmospheric condition, a teleconverter may not be the best option.

Converting Your Full Frame Lens To APS-C with a Speedbooster (telecompressor)

Speedbooster lenses (likewise known and telecompressors or focal reducers) are pocket-size lenses that permit full frame lenses to be used with APS-C cameras without losing any of the paradigm. It substantially allows y’all to have a full frame field of view on an APS-C camera.

This kind of lens can be near easily understood in that information technology is the opposite of a teleconverter lens. The lens reduces the focal length which then has a domino effect of the F-number of the lens. So, when you mount this and your full frame lens onto an APS-C photographic camera you are basically condensing all of the light onto the sensor giving yous the full frame view.



Speedboosters assist produce a noticeably sharper image, gain of a cease of light and a shallower depth of field. This is great for portrait photography.


Unfortunately, most speedbooster lenses exercise not come with autofocus which may have some getting used to. Just like the teleconverter lens, in that location is also a drib in resolution effectually the edges of the paradigm at larger apertures despite the center still existence sharp.

Hither are some speedboosters you tin buy.

I promise this article cleared up the topic of APS-C and total frame lenses for you.
