this lens is sharper this lens zooms in further this is going
to be better in low light but this has oss which do you buy
the 24 to 105 f4 doesn't sound like anything special on paper canon has this exact lens
in rf mount and it's considered a kit lens i normally look at these lenses and just assume
yeah it's going to be okay but i thought the same thing about the sigma 24 to 70 and now i love that
so let's compare these two lenses and if you're wondering why are you going to do that well if
you're looking for a one and done lens if you buy one lens and you're done these are
probably both in your shopping basket things we're going to be covering in today's video
on screen right now expect examples of all those because that's what i like to
do everything in today's video was shown a combination of the sony a7s 3 and the a7 iii
both full-frame cameras and i thought that was the fairest way to do this let's kick things
off with autofocus now for this test i had both cameras set to continuous auto focus the focus
mode was wide on both cameras the sensitivity autofocus speed was the highest it could go
and then on the a7 s3 i had the transition speed set to slap bang in the middle as it comes out
the box because the a7 3 doesn't have that and that's the fairest way i could do this test
take it away chris all right auto focus test with both lenses at f4 shutter is cranked
because i didn't bring endes out the frame back in the frame close out and back in
let's take a look at the sharpness and optics of both of these lenses side by side now i'll keep
this quite straightforward at 24 mil both of these lenses suffer from pretty bad distortion
the sigma is a little bit worse than the sony and the sony has worse vignetting than the sigma
both of these issues can be corrected in lightroom pretty easily side by side at 24 mil f4 it's kind
of hard to tell which lens is sharper than the other however if you zoom into 50 mil and then
70 mil which is the three tests i performed 24 50 and 70 you can tell that the sigma is definitely
sharper in the middle now that being said in the corners it does appear that the sony is a little
bit sharper i then did exactly the same test at f 8 so 24 50 and 70 mil and it's clear across all of
those focal ranges that the sigma is sharper in the middle and at the corners it's not a massive
difference but if you zoom in a little bit in the photos it's pretty obvious here's a little test of
myself doing selfie just a test i like to do just to show eye sharpness now again both lenses were
shot on the same body and it grabbed my eye both times i saw that little box around there side by
side 24 mil f4 it's kind of hard to tell which is sharper than the other if you start to look at my
hairy eyebrows you'll notice that it's a little bit more defined on the sigma so arguably it's
the sigma has the win here too but it's pretty hard to tell if you want to do your own tests the
side-by-sides to take a look at the raws i'll pop all the images down below for you as well if you
wanted to vlog with each of these lenses at 24 mil here's how that would look hey if you like this
video chances are you probably will like the other videos i make too so maybe try hitting subscribe
down below alright thanks so if you were to vlog with these lenses this is how it both look at 24
oss turned on on the 24-105 and is a little bit further away than how i typically hold it because
i'm holding it with the tripod between my legs like this so this is how i'd look to vlog
with both lenses at 24 if you're interested let's take a look at how your focal lengths differ
and that's why we put our phone on silent or not hey hey i'm trying to film a video you know yeah
i know i'm sorry it won't take long to be out getting test shots today i am i'm shooting the
24 to 105 versus the 24 to 70 i got both cameras rolling right now but i just thought of something
and that's why i wanted to call you so what's up so now you're filming your video today can you
tell them about the desk and the desk the new one that got sent no i'm not doing that
why just tell them it won't take long i know you like it why don't you do it in the edit you can
find somewhere to splice it in okay then well i will definitely do that it's a standing desk
from a brand called flexispot and full transparency they did send this through
for me to take a look at but i have been looking at standing desk for a while as soon as i hit 30
downhill from my back from there i spend a lot of time sitting i want to do less of that because i'm
editing all the time so a standing desk is a way to do that standing up better posture for my back
this model is the ec1 it goes up to a maximum height of 48 inches which is actually right there
i'm six feet so you can kind of gauge how high it is actually a little bit too high right now
my arms are going up so it should go down a little bit when i want to sit and have a chair here it
goes down to a comfortable 28 inches and it's incredibly easy to use very straightforward two
buttons if you want to go up you hold up you want to go down you hold down it's as simple as that
a baby could use it now there are other models that have like a control panel with presets there
and a little monitor to show you how high you are but i mean up and down it's pretty straightforward
it was easy to put together as long as you've got like a power screwdriver 30 minutes good to
go plexus spot will give you free shipping and you'll get 15 of your first order if you click
the link down below back to the video the sony is gonna give you more zoom let's take a look at how
the focal lengths differ now obviously one of the biggest reasons to go for the 24 105 over the 2470
is the focal range so i'm going to zoom right in down there so you can see the difference you get
from 70 to 105. so right now we're at 24 on both lenses and we're gonna go to 70 on the 24-105
which is right there and then the 70 on the 24-70 sigma now the 24-105 can go a little bit further
so that is your extra reach from 70 to 105. back out to 70 just for comparison
the framing might look slightly different as the cameras are at a little bit of a different angle
back to 105. so this gives you about 30 more reach from the sigma where the sigma ends at 70 this
goes all the way in to 105. now some situations if you can't move forwards or you can't crop in
that's going to be pretty useful and you're going to know which situations you're going to need that
for if you shoot those kinds of things optical steady shot something this lens has which the
sigma does not right on the side right there oss can be turned on and off directly on the
lens and a big reason to pick this lens over the sigma and it makes a difference especially when
you're zoomed all the way in there you will definitely see more shake when you're more
zoomed in but this next test i was using this setup here i had both cameras attached to this
plate and i was hand holding it and i turned off steady shot on both camera bodies to make it fair
okay so both lenses are at 24. oss is turned off on the 24-105 and steady shot is turned
off on both of the camera bodies here now this is a bit of a heavier setup so you're probably
not seeing that many micro jitters anyway weight always helps with those kinds of things i'm now
going to go ahead and turn oss on on the 24 to 1 f5 so any little micro jitters that we did have
are now pretty much gone or at least smooths them out it's a much more
pleasing handheld look so now we're at 70 and you're probably seeing a little bit of jitters
now i'm going to turn oss on on the 24 to 105. and it will now smooth out a lot of that
so that is with oss on turn oss off once again that is oss off on 24 to 105 and back on so that
is why having optical steady shot is sometimes pretty useful when you're zooming in and a quick
note here if you have the sony a7 s3 it has active steady shot which is fantastic and works really
well but if you try and use it with oss in a lens you will see little bits of weird warping
in the corners i've heard it from other people and i have experienced it myself so you've been warned
if you have active steady shot either use that or rss don't use both together now another point on
that the a7s iii having active steady shot is incredible and to be honest with you i've been
using the sigma 24 to 70 f 2.8 with it for a long time and it does a real good job so oss is great
but if you have the a7s 3 you have active steady shot so something to think about all right low
light performance f 2.8 versus f4 it's easy to say which is gonna be better it's the f 2.8 in
case you didn't know but how does that translate into a real world situation where you're using the
same settings with both lenses how different is f 2.8 to f4 let's take a look so what we have right
here is just a demonstration to show you at f 2.8 on the sigma 24 to 70 how this looks and
now we're going to turn on the f4 on the 24-105 on this camera right here now this is purely just an
example to show you i don't really know which lens to look at um you could counter the differences
with iso it's just so you can see between f 2.8 and f4 how it looks in a low light situation
here's another test same settings on both cameras f 2.8 on this one f4 on this one this is how
it differs between f 2.8 and f 4. put on this side just so you can see go down here facing up
that's the difference between f 2.8 and f 4. bokeh dog hair whatever you want to call it
little example here to show you the difference between f 2.8 and f 4. in this example the lens
i was shooting you're going to see is like here and then the fairy lights are like here
just the example i'm showing you right now so we're at f4 right now that is f28 back to f4
f28 build quality and pricing now lenses go on sale all the time both of these are included in
that the sigma isn't on sale right now but it's 1098 u.s that's his regular price this regular
price is 13.98 but is currently on sale for 11.98 sony's giving you a 200 rebate so they're about
100 difference right now and very similar in terms of price in terms of height don't
be fooled by the lens hood the lens hood is what makes them look different in size they're actually
very similar in terms of height and the lens hood on the sony when it goes on it sounds like this
looks like a very dissatisfying click whereas on the sigma it's like uh
sounds good i like the lens hood click on that one that's not something you care about is it the sony
lens is on par with all of sony's other lenses if you have any other sony lens it's that brushed
kind of black finish on them whereas the sigma is a combination of matte and shiny finishes both
lenses have decent zoom rings but the sony one is a lot firmer to turn compared to the sigma one if
we actually extend both lenses all the way you'll see that the sigma actually compresses itself the
focus ring on the sigma is nearly double the size of the focus ring on the sony however it's a bit
loose on this one i've always said that it's not bad it's just when you use a sony lens you realize
how good they they do their focus rings and i gotta say if i'm honest i prefer the focus ring
on this compared to the sigma one i'd like the width of this on this if possible please sony both
lenses have the little button on the side there you can assign it to different things common thing
i like to use it for is eye auto focus minimum focus distance on this is 0.38 meters or 38
centimeters and on this one it's 18 centimeters so it's a fair bit different what does that mean what
means you can get a lot closer to your object with the sigma than you can with the sony and
this is going to be in focus like 20 centimeters closer than this will be let's talk about dust
quickly because this comes up all the time when i talk about this lens if you get bothered by dust
being in your lens i'll be if it doesn't affect image or photo quality or video quality in any way
do not buy the sigma i'm not going to go into detail why i'll link my other video up here where
i've talked about it in a little bit more detail this i've had for six months and there are specs
of dust in it this i've had for best part of a month there's not a trace of dust in there so
just go watch that video and makes more sense so many people care about how their lens looks
compared to how it performs it doesn't affect your image quality that's all you need to know so this
lens is sharper this lens zooms in further this is going to be better in low light but this has oss
which do you buy this is a tricky one and ultimately i can't make the decision
for you it has to be up to you that's why i made this video it demos the differences between these
two and hopefully allows you to or helps make your decision for me if you have an a7s s3
the sigma is the clear winner you don't need oss because you have active steady shot which works
fantastic this is cheaper it's faster better in low light f 2.8 versus f4 and it's sharper so this
is the winner if you have an a7 s3 however the reason that i picked up this is because i want
to buy an fx6 and we can finally buy them they're backwarded everywhere that doesn't have any form
of stabilization built in so the oss is really useful the extra focal range would also come in
handy if you are going away and you want to shoot a wide variety of things or you're traveling and
you don't want to bring other lenses with you also if you don't have an a7 s3 any older sony camera
has steady shot but i'll be honest it's not great compared to active steady shot so the oss is going
to come in handy for you so that is my thoughts on it but as i said ultimately you're the one that
has to make the decision and a lot of you going to ask why didn't you throw the tamron in the mix
i'll link you my video up there covering the tamron i've owned it i've sold them
they just never had a wow factor to me the image quality was okay it wasn't anything special and in
low light i didn't find the autofocus to be that reliable so yeah just go watch the video that
makes more sense and that's that thank you for watching today i hope you got some value out of
this if you're looking at buying either of these two guys otherwise i'll uh see in the next one
you
