hey guys welcome or welcome back thanks so much for joining me today we're going to talk about
essentially the actual difference between cropped and full-frame cameras
so we're in quite a straightforward location it's just a woodland close to home and we're going to
shoot using a full-frame camera but it's got a button on it that means i can crop it to look
like it would do in a crop sensor camera so i want to walk through that with you because
i think there's really big misconceptions about what the difference is between a full frame and
a cropped sensor camera and what the difference is when you use potentially some of the lenses that
i've recommended in the past on a crop sensor camera what actually is the difference so for
the purposes of today's video i'm not actually going to be talking about the physics behind
the sensors all you need to know is that a full frame sensor is actually larger than a crop sensor
camera okay there is a crop factor which you will probably already be aware of for your camera so
for example the canon crop sensor cameras are 1.6 times crop factor most crop factors are usually
1.5 times but some of them are two times so that's a micro two-third micro four-thirds the other one
what actually are we going to discuss today well a lot of people get have a cropped camera a crop
sensor camera and they buy a lens like the one three five one eight or a seventy to two hundred
and they buy a full frame lens and then use it on a crop sensor camera and there's nothing wrong
with doing that really but it does make a big difference in terms of like the blurriness of
the background loads of people say loads of people say that when you use a say a 200mm
lens on a crop sensor camera it becomes 300mm but that's not true it is in terms of the crop on it
but it's literally just cropping down so instead of going over this and talking about it for ages
i'm just going to show you the difference really we've got bryt we've got a track behind us
there's some bright light it's not going to be an award-winning photograph but it will demonstrate
this point in action okay so we've got a sony a7r iii with a 7-200 lens we've got full-frame camera
with a full frame lens and this is relevant for full-frame lenses kind of only but generally
in general so what we're going to do is we're going to illustrate what an image looks like
when you've got a full frame camera and what the same image would look like if we moved and shot it
at the same scale in a crop sensor camera which is the point of this whole video
sit wait so beanie's going to sit and wait i'm going to do a wait wait and do a landscape image so
we can see on the full-frame camera that i'm sat down here we're nice and low down
and we've got a shot good wait now if we were on a crop center camera it would look like this
so there's nothing wrong with that it's just a much tighter image
so without zooming out we would need to get to the same scale wait
should be about there now because we've changed the distances wait involved
because of that change we've also affected the bokeh we've affected the separation okay good girl
super so the point isn't that it crops in the point is that you need to move further away
and it's that movement further away that has a direct impact on the blurness of the background
so it's not really to do with the fact that you've got a longer lens although it can be
helpful in some situations but for portraiture the main thing is that you need to be further away
for every shot that i take on a full frame to get the same composition
you would need to be further away and therefore the distances all change so we've gone to a much
closer location so the difference between this track and the other track is quite massive so
let's set up the full frame shot and then switch and do the same shot crop sensor my line i need to
be no further really than that so beanie's gonna have to be here beanie beanie good wait
beanie is in a certain way wait i'm going to do portrait shot
wait i'm going to keep the same vocal length ready wait
ready wait
and i'll do crop sensor so usually about that far back ish wait
good wait
okay good girl super so the crop sensor camera can make an absolutely beautiful photo there's
no doubt about that you don't need to have a full frame camera you just have to be aware
of your distances because when we look at those shots we've got a difference there in terms of
the background so the difference in the bokeh is actually quite large it might not be that
clear for you to see but it is quite large so there is quite a big shift between the bokeh
and the background rendition just because of your distances so you could keep the same bokeh
of rendition by moving the subject further away but in terms of that line by moving further away
i'm then going to be sat in all of this bushy stuff there's bushy stuff which will probably
cover over the lens and it's really spiky so i'd really rather not so in terms of your crop factor
no you don't need a full frame camera to make a beautiful photograph yes it does
make a difference in terms of your lines and your composition what's the benefits of having a full
frame camera usually higher dynamic range better handling of noise larger file sizes usually better
pixel rendition better colors there's all sorts of other benefits but the main one that people
tout is that you get better blurry backgrounds not true because it's all about the distances
so i hope that helps to clear that up if this video has been helpful please do let me know and
yeah it'd be great if you could subscribe beenie you can't eat pine cones i'll see you again soon
