Why I don’t shoot on Full Frame Cameras… yet | Crop Factors

September 26, 2019


What’s going on everybody? Potato Jet here. Today we are talking about crop factors. But I think I’m gonna title this video, Why I Don’t Shoot With Full-frame Cameras and I think that’s a little
bit more interesting sounding than Understanding Crop Factors. I don’t know, I might one day switch to a full-frame camera,
so if that day ever comes then this video will awkwardly be sitting in my video playlist. But I don’t really like
to think that far ahead. So, we’re Gucci, I probably
shouldn’t say that word, Gucci. In order to be allowed to say that word, you have to have a certain level of swag. If you have more than that level of swag, then you can say it all you want. It sounds good, it works. But if you’re below that
line you just sound stupid. I’m like right there, like
I could almost say it, but it’s just better for the entire planet if I never use that word again. What was this video about again? Oh, crop factors. The biggest misconception is that all 35mm sensors are the same, which is very much not true. It sounds about right, right? Like if someone says, my
sensor’s 35mm. You’re probably like, oh, that’s probably the dimension of the width, or height, or something like that,
but it’s actually not true. And if someone tells you their
sensor size is 35mm it could mean something
very, very different. It all goes back to before
we had digital cameras, to when everything was shot
on film, those long film strip that you imagine people
in a dark red room, snipping away, and cutting together. 35mm film is a strip,
and it’s 35mm wide. Now, let’s start by
talking about photography. In a film camera you
take this 35mm, you stick it on one side, you stretch it over to the other side, close it up, and the film goes through horizontally. It burns that image straight
onto that film strip, utilizing as much space as
it can without flooding over. And the image you can
place within that space is about 36 by 24, and they
call that 35mm in photography because it’s
on a 35mm film strip, not because of the dimensions
of the photography. So, if you hear full-frame 35mm, it generally refers to
photography, which is this size. The Canon 1D Series,
the 5D, 6D and a bunch of other cameras out there
that shoot full frame, in photography, that’s the
size they’re referring to. Now, here’s where people get thrown off, is they hear Super 35, or
35mm for video, which is actually a very,
very different size, and the main reason is because in traditional film movie cameras, the film gets fed in vertically,
so, it goes up and down. For example, this is a 16×9
frame that you’re looking at. Let’s squeeze this down, and
fit it onto a film strip. Now, if you look at throwing
it on a vertical film strip, notice you have to compress it way down because of the edges here. If I go any further out this way, then it’s gonna bleed
out onto the holey part. I’m sure there’s a proper name
for that, I never shot film. But let’s take this same image, throw it onto the horizontal one, then you can stretch it way bigger. So, that is why Super
35, or 35mm film for video is much smaller. In cameras that utilize the
Super 35mm sensor are like the Sony FS7,
the Canon C300 Mark II, this RED camera, a
majority of Arri ALEXAs. Now that we’re going digital, we’re no longer really restricted to this 35mm film strip so companies are exploring
these larger sensors like the Sony VENICE, the Arri ALEXA LF, and the RED Vista Vision MONSTRO. But keep in mind that 99% of everything you see on TV and theaters are still shot on Super 35mm sensor sizes. So to summarize, the two you’re gonna hear most often is
full-frame 35mm, which is the big one for photography, and Super 35 which is the most common one for video which is the vertically fed one, so it’s a little bit smaller. Full-frame, big, Super 35, small. Now when it comes to smaller
cameras like this Canon M50, a lot of times the sensor’s smaller and it’s cropped in a bit
which has crop factor. This is one of the most common sensors, it’s an APS-C sensor which
has a 1.6x crop factor. And some cameras like
the Micro 4/3 cameras have a 2x crop factor. So if you’re shooting on the same lens, if you’re shooting with
a cropped in sensor, it just appears to be more zoomed in. So for example, right now
I have a 1.6 crop factor on this camera and I’m
shooting on a 10mm. But since it has that 1.6 crop factor, it looks more like a 16mm, and if I zoom it in, let’s see, now this is a 18, it’s
18 times 1.6 which is… Someone give me an abacus, quick! Now when we say a 1.6 crop
factor for something like this, we’re saying it’s a 1.6x crop
to a full-frame 35mm, not a Super 35, a
full-frame 35mm. So yeah, a 1.6 crop factor
sensor is quite a bit smaller than a full-frame 35mm sensor but it’s actually not too different from a Super 35 mm sensor. So the sensor size between this and this might not actually be as big as you think. So basically if you tag an awesome lens on to this camera to try
to get cinematic images, the sensor size is not gonna be the thing that’s gonna limit you from
getting awesome images. I’ve considered going to a
full-frame camera a couple times specifically the 6D Mark II,
looks pretty appealing to me. Now aside from it being much bigger and more expensive than this camera, you also have to go to a full-frame lens. This lens is much cheaper and much smaller because it only has to
cover an APS-C sensor. Once you get a lens that can cover the entire 35-millimeter
full-frame sensor, then you can’t use this, you have to go to a much bigger lens. That this is big, heavy, and expensive. Another reason why a lot of
people love full-frame is for shallow depth of
field, it looks awesome. Admit it, we’re all a a
little bit overly obsessed with shallow depth of
field, it looks awesome. But have you ever tried to focus on somebody going in
and out from the camera and trying to keep them
in focus the whole time? It is tough. Autofocus is getting much
much better on cameras so that’s becoming less
and less of an issue but there’s still plenty of
people shooting out there manual focus for video for a good reason and doing this motion
with a full-frame camera with like an F1.8 would be impossible. You would lose focus on me so fast. I’m definitely not saying APS-C and Super 35mm sensors
are better than full-frame, that’s just the reasons
why I personally shoot with this 1.6 crop factor camera. Also, keep in mind that I
only really shoot video. If you shoot a lot of photography, then full-frame makes a lot more sense. You can go as shallow as
you want in photography because you only need that perfect, precise focus for that split second. You don’t have to keep the subject in focus consistently for
a long period of time. And with those big ol sensors, they generally have really, really, good low light capabilities. And Arri, my absolute
favorite camera company, they make the Arri ALEXA. People have always asked them why they don’t put more
pixels in their sensors. They obviously have the
technology to do that now but they say when they take their sensor, throw more pixels in there, then they have to take every pixel and make them even smaller. And they always say
they prefer the quality of a pixel over the quantity of it. So, hey, Arri says big
sensors are a good thing. I do think when you go
to a full-frame sensor and get that bigger sensor, you do get an improvement of quality. I really really wanna test
out a side by side comparison with something like this
to a 1DX or 6D Mark II and see side by side, like
how much of a difference does it actually make when
you’re literally looking at them side by side. Is that something you
guys might wanna see? If enough of you guys wanna see that then I might put that on
the to-make video list. My guess is that there is
gonna be image improvements but I think this is
gonna come super close, closer than most people think ’cause I do think a lot of
it is also kinda mental, like if you’re shooting
full-frame, you’re like, wow, this is full-frame,
I’m shooting full-frame. But I’m telling you the results out of these little guys, pretty solid. The sensor size obviously
makes a big difference but at the same time, it’s still, again, just a small part of the big picture. Anyways, enough about crop factors, I think you guys get the point but I’m also putting
together a full video course. But I wanna hear from you guys if there’s one thing that you
guys wanna hear me talk about or answer a question, let
me know in the comments and I’ll try to include as much of it as I can in the full course. I’ll see you guys later. I’m heading to Mexico next
week, a city called Loreto. I’ve never been there,
don’t know much about it, but apparently it’s only a
two-hour flight from Los Angeles. Beautiful beaches, tequila,
should be a good time. I’ll finally be able
to test this thing out, PolarPro sent it to me but apparently, you’d stick your GoPro in there and you can get shots
where it’s half above water and half below, should be interesting. I’ll do giveaway on this too, next time. So yeah, see you guys later.
