Are Canon’s APS-C Sensors Really Worse Than the Rest?

eos m50

The Canon APS-C sensor is a 1.6x crop and smaller than the rest of the industry’s, but is it worse?

One of the more significant concerns of many photographers has always been about Canon’s APS-C sensors. Though their cameras are dwarfed by the likes of Fujifilm, Sony, and Nikon, they have always marched to the beat of their own drum. While the rest of the industry goes with 1.5x crop sensors, Canon has forever gone a bit smaller with 1.6x crop. It sometimes worked to their advantage when translating their focal lengths over. But has the quality always been worse?

Photography Cheat Sheet: How Crop Factors Affect Depth of Field

We’ve created a handy photography cheat sheet for you to figure out the crop factor of a lens and the resulting depth of field.

Figuring out the crop factors from one camera system to another can be a bit tedious. Remembering what camera system uses what sensors is also a bit annoying, so we’ve come up with a full Photography Cheat Sheet to help. These are all primarily based on the 35mm frame, otherwise called Full-Frame. From that format, you figure out a whole lot of variations depending on what you’re looking at. That’s why some manufacturers make odd focal lengths that sometimes just don’t make sense.

Eight Wide Angle Lenses Under $700 for Landscapes on APS-C Cameras

These wide angle lenses are perfect for landscape photography, even with APS-C crop factors thrown into the mix.

When shooting with APS-C based cameras, getting a true wide angle lens can be slightly challenging. With crop factors ranging from x1.5 to x1.6, it’s vital to take into account that the lens you shoot with will not be quite as wide as you thought. For example, a 15mm wide angle lens on a APS-C based camera will have an effective focal length of 22.5mm-24mm depending on the crop factor of your camera. Fortunately there are some spectacular lenses out there that are still nice and wide even with the crop factor of your sensor. The best part is that you can get some optically stunning lenses for under $700. Continue reading…

The Phoblographer Answers: What Does the MM on a Lens Mean and Stand for?

If you’re into photography, you most likely know the answer to the question “What do the letters ‘mm’ on a lens stand for?” But for the uninitiated and for lots of Americans who don’t know the metric system or what millimeters are, it can be pretty confusing. I mean, we can understand that eight inches is larger than two inches, right? So bigger, must mean better, right? No, not exactly and that couldn’t be further from the truth.

Essentially, the wider the field of view, the smaller in focal length number. The more narrow (telephoto) views are larger in focal length numbers. So, a 14mm lens will give you a wider field of view than an 85mm lens. But then things become even more confusing as pretty much every standard of focal lengths are then more or less based off of 35mm film.

The mmCalc Crop Factor Calculator Makes Sensor Math a Snap

mmCalc Crop Factor Calculator

Sensor Size math isn’t a problem with the mmCalc Crop Factor Calculator. If you haven’t figured it out by now, there’s a lot of math involved in photography. One of the places you’ll often notice where math and photography intersect is in discussions of sensor size. If you’re trying to make apples to apples comparisons of photography gear, you’re usually talking in terms of full-frame equivalents. Often this will require some mental math (and sometimes not-so-mental math) to determine the crop factor. Or you can skip the arithmetic altogether by using this crop factor calculator by mmCalc.

An Explanation of How Crop Factors and Depth of Field Correlate


Full frame, APS-C and 1/2.3

A blog post that published recently was the source of a bit of confusion for some, so we decided to explain how it all works. But when this subject is talked about, it is often talked about only in terms of full frame 35mm imaging sensors, APS-C sensors and Four Thirds sensors.

Crop factor and apertures/depth of field absolutely totally correlate in many ways and therefore also greatly affect the way that the image that you create will look. For many photographers, this is the biggest determining factor of the type of camera and sensor/film they will use.

On ‘Crop Factor’: What it Means And How to Apply it to Your Photography

Olympus E-P1 + Adapted 50mm Lens

When adapting the lens of one camera system to another, you may not always get the same results. Part of the reason is that your camera system may have a smaller sized sensor than the system the lens was made for. This will lead to an image that appears ‘cropped’ compared to an image taken with the same lens on a camera with a larger sensor. We’re speaking of the so-called ‘crop factor’, which determines the difference between the appearance of images taken with cameras with different sensor sizes, but the same lens. After the break, we’ll go into detail how the crop factor is calculated, and how it relates to a lens’ focal length and other properties.

Recommended Lenses for the Micro Four Thirds Mount Black Magic Cinema Camera

Black Magic just announced a Micro Four Thirds version of their already popular Cinema camera. In my honest opinion, it should have been Micro Four Thirds mount to begin with. The mount, though, is passive, which means that electronics will not work. So for the most part, say goodbye to most of your Micro Four Thirds lenses.

But there are some that will natively work with no problems at all. Being the hackers that Micro Four Thirds users are, though, everyone tries to find old and alternative glass to hack onto their camera bodies. Because of this, nearly any lens you can think of has been adapted to the format.

Here’s a list of some glass that you may want to check out:
