Canon webcam topic revisited: Why sensor size affects image quality (Mac compatibility on the way)

I previously posted this list and didn't even think about the sensor sizes and formats and why it matters to the non-camera enthusiast. I will try to do a concise breakdown under this mage list of the compatible cameras and point out why this may be worth time and expense. Please note this webcam utility is for Windows use only at this time. Canon says they are working on Mac compatibility.



Canon SLR cameras can be broken down into 2 sensor size classes.
The 1DX Mark II, III, 5DS/R, 6D Mark II are full frame sensors which means the sensors match the 35mm format of the film days. The 1 and 5 series are professional use type cameras with the 6D series being prosumer/enthusiast.
The 7D Mark II, 700D, 80D, 90D are aps-c sized mid-range prosumer/enthusiast type camera. The SL2/3, T6/i, T7/i, T100 are fps-c sensor sized compact entry level cameras. App-c is a smaller sensor often refferred to as 1.6x (Nikon call their DX).

The Mirrorless series breaks down along sensor lines of Full frame and Aps-c as well. Unlike DSLR, there is no mirror box and mirror that flips up. This is where some of the market is moving since SLR format has been around for quite a while.
The EOS M6 Mark II, M50, M200 are fps-c sized sensors. Typically these are Sub $600 on the used market.
The R and RP are pricier full frame cameras that tend to be more for pros and enthusiasts. These are typically $1k and up on the used market.

The power shots listed have smaller than aps-c sensor sizes. The G5X Mark II and G7X are the 1" sensor and the SX70 HS 1/2.3 inch. These sensors are smaller than the 1.6X and full frame.




This chart below show you the size of sensors including webcam. smart phones, and tablets. The physical size is much smaller. Generally, larger sensors have less pixels crammed into them and image quality improves. Larger sensors combined with certain lenses can also make blurring the background easier. This is why an iPhone can have a lot of the subject and background and subject in focus while a full frame SLR needs to have more precise focus. Canon has marketed their cameras as still and video cameras ever since the Canon 5D Mark II. An iPhone can do the background blur they call Bokeh mode but it is a software solution. Can someone chime in and tell me if bokeh mode works in FaceTime or webcam mode?

An Aps-c sensor camera will perform better than the smaller sensors such as webcams and phones but tend not to be as costly. The larger sensors typically bring a larger price tag. For instance, a used 77D app-c sensor runs about $500 on the used market while a 6D Mark II full frame is about $1,000. The T series cameras may have similar sensors to the 77D but the body and feature list is less robust.

What do you typically get by making the jump to a larger sensor over your webcam or iOS device?
1. Higher image quality (better colors, less noise, less amplified dancing pixels in low light)
2. More light gathering with certain lenses
3. Ability to background blur (with certain lenses and sensor sizes)
4. Exposure control
5. More audio recording options and better mics







Knowing all this, you will have to ask yourself if the gains are worth your time and expense. For me, if I am going to be on a video conference with a high end client, I would use this larger sensor plus a nice lighting and audio. Image may matter for both meanings.

If worst comes to worst and you spend this money and all returns to normal, you have a new hobby.

The case for the Canon T6 as the least costly option of the Canon webcam capable cameras.


Pros:

Better image quality than a webcam since the sensor is larger. Your colors and overall image should be less muddy. Your colors will be truer and have more saturation and depth.

Ability to manually adjust the exposure (lighter or darker).

It can be had on the used market for around $150 for the body, $199 with the typical 18-55mm kit lens.

The mic built in isn't too shabby. The body has no mic port. If you are on a laptop, the Mic port can be used for an external mic or use your laptop's mic port. This wireless lab mic is nifty for $40 $40 wireless mic

You can buy different lenses such as ones that let in more light.

The camera can be a side hobby. If you already have this hobby, it can be a backup camera.



Cons:

Windows only

No flip out LCD

No autofocus in video mode. Doesn't matter much of you are stationary

Shows more of your facial imperfections

One could pick up a Lumix mirrorless on the used market for a very cheap price, with the flip around screen (and decent stereo mics).

The 4/3 system sensors are larger than webcams. Does Panasonic have a webcam utility for this camera?

I only know of people using them, don't know if there is specific webcam s.w.

Canon's needs the Canon Utility software for setup and that is why it is only Windows at this time. You can then use any video platform once setup is complete.

Some people are reporting the Canon webcam utility works for the T2i, 70D, 6D. Look in the comments section [www.youtube.com]
There may be some hiccups with non listed models.

Canon is also working on a Mac compatible version!

Be sure your nose hair and eyebrows are trimmed! And you men, also...
