hi I'm Dustin Abbott and I'm here to
0:12
review a very unique lens from Siri this
0:15
is their autofocusing 1.33 times
0:18
anamorphic 40 mm T 1.8 lens it was
0:23
perhaps inevitable that sir eyes focus
0:25
on anamorphic cine lenses and then their
0:27
new shift into focusing on autofocus
0:30
lenses would come together and the
0:32
result is a very fun lens an
0:34
autofocusing 1.33 times constant squeeze
0:38
anamorphic 40mm T 1.8 cine lens this is
0:42
a lens like we really haven't ever seen
0:45
before and it reflects the fact that
0:46
cameras are increasingly hybrid devices
0:49
that are just as capable of capturing
0:52
high-end video footage as they are in
0:54
capturing greatl looking Stills there
0:57
has perhaps never been a more versatile
0:59
tool an easier way to get runand gun
1:02
footage that actually has that wide
1:04
letter box syny kind of look and so this
1:08
lens is going to be a lot of fun for a
1:10
lot of content creators so is it a lens
1:13
worth buying at anywhere between about
1:15
$650 and $800 depending on whether you
1:19
get it on sale well that's what we're
1:21
going to find out in today's review now
1:23
today's review is going to be a little
1:25
bit different whereas I will do some
1:27
traditional sections where I take a look
1:29
take a look at the build and handling
1:30
and the feature set of the lens as well
1:32
as the autofocus the image quality
1:34
portion will be a little bit different I
1:36
am going to demonstrate some of the
1:37
optical qualities that I look for and
1:40
demonstrate that with some specific
1:41
footage for that but then I'm going to
1:43
just show you a short film that we put
1:45
together taking just what just taking
1:48
Run and Gun footage without any
1:50
additional equipment just a camera and a
1:51
lens and splicing that together to just
1:54
show you in real world scenarios how the
1:57
optical qualities carry out with the
1:58
lens and give you an idea of what you
2:00
can create and this is without any kind
2:02
of grading or additional steps it's just
2:05
de Des squeezing the footage putting it
2:07
together and and just producing what was
2:10
there so it give you a real idea of what
2:12
the lens itself is capable of so we're
2:15
going to start by taking a look at the
2:16
build and handling this is being
2:17
marketed as an S35 or an apsc lens
2:21
though in my experience it seems to
2:22
cover the full frame image Circle just
2:25
fine on my Sony bodies and actually I've
2:27
used it mostly in fullframe form and
2:30
then only it switched to the apsc or the
2:33
S35 when I wanted a different focal
2:36
length so this is a 40mm lens which I
2:39
would say is a focal link that is
2:40
actually growing in popularity right now
2:43
this is actually probably a little
2:44
closer to 42 mm on full frame it's a
2:46
different ratio but you know they're
2:48
marketing it as 40 mm so that's what
2:51
we'll go with here you can switch into
2:52
the 1.5 time S35 crop and you have a
2:55
full frame equivalent of 60 millimet
2:58
which is another interesting focal
2:59
length now the anamorphic squeezed here
3:02
is a constant 1.33 times or that is a
3:06
2.35 to one ratio when you're shooting
3:08
on 169 so if you're shooting on 169
3:12
format you're going to have some of the
3:13
black bars on the top and the bottom of
3:16
the footage and of course that wider
3:17
cinematic look um that kind of letter
3:20
box look after doing the dis squeezing
3:23
and that is a look obviously that's very
3:25
desirable for a lot of people because
3:27
automatically because people are
3:28
accustomed to seeing films that are shot
3:30
in that style they automatically start
3:32
to think a little bit more cinematic
3:34
than just your typical 169 ratio that is
3:37
standard with every other lens that
3:39
you're shooting with on your camera now
3:41
the t- stop of this lens is T 1.8 which
3:44
means that it is moderately bright and
3:47
also that it can create a fairly shallow
3:49
depth of field though again you know you
3:51
have to realize 40 mm is not super long
3:54
and f1.8 is not incredibly uh bright and
3:58
so the depth of field is going to be
4:00
somewhat dependent on that there are a
4:02
variety of lens mount options which
4:04
includes Sony e-mount I've tested here
4:06
Nikon Z Mount Fuji X Mount even micro
4:10
4/3 is a fourth option available out
4:12
there as befits a Sy lens both the
4:16
aperture ring and the focus ring they
4:18
are geared with the standard teeth and
4:21
there is a 360° throw rotation for the
4:24
focus ring it does operate in a linear
4:27
fashion MSRP is going to be
4:30
$799 but there is an early bird special
4:33
that will allow you to get about 150
4:35
bucks off that if you happen to land the
4:37
deal you can choose between two
4:39
different versions of the lens that
4:41
includes a Blue Streak or blue flare
4:44
version which is what I tested and then
4:46
the natural warm streak streak versions
4:48
there as well I found that there are
4:51
definitely some of the recent Aurora
4:54
885mm f1.4 design cues that are here
4:57
terms some of the fonts and the Fe feat
5:00
set the position of certain things the
5:02
lens itself physically is 80 mm in
5:05
diameter or 3.1 in that's important
5:08
because it does give you a standard mat
5:10
box um overall size here at the front
5:13
and so that you can mount that on there
5:15
the lens is 120 mm by my measurement in
5:18
length or 4.72 in it weighs in at a
5:22
moderate 614 G or 21.6 o people that are
5:27
accustomed to shooting with cine lenses
5:28
are accustomed them to being a little
5:30
bit bigger and heavier and so this lens
5:32
really is moderate in size and weight
5:35
it's not really going to be an issue for
5:37
anyone I doubt now there is a robust
5:40
approach to aperture control in a way
5:42
that you're not accustomed to seeing on
5:44
C lenses because usually they don't have
5:45
autofocus you have the ability to both
5:47
click and declick here and so it you can
5:50
do the smooth racks all throughout or
5:53
you can have clicks at the onethird
5:56
stops along the way you have also have
5:58
the option here over over on the left
6:00
side you can have an AF MF switch and
6:03
then you have a function button that
6:05
will allow you to program different
6:07
functions there from within the camera
6:09
now the aperture Iris itself is 11
6:11
blades but it's not 11 rounded blades in
6:14
the typical way that a Stills lens would
6:16
be it does have an oval shape in fact
6:19
when it's wide open there's a very
6:20
distinct hexagonal shape that uh you'll
6:24
either love or hate I'm more in the
6:26
latter portion and it turns to a more
6:28
traditional oval C look when you stop
6:31
The Lens down as you can see here at
6:34
f2.8 as noted the focus throw here is
6:38
360° manual focus and so that means that
6:41
it's long if you want to do major Focus
6:44
throws but it gives you Precision in and
6:46
out of there there is a USB C Port that
6:49
is located here on the lens mount there
6:51
is also some weather ceiling with a
6:53
gasket and some Coatings and I believe
6:55
some internal seals as well minimum
6:58
Focus distance isn't great it's 60 cm
7:01
which gives you a very low magnification
7:03
level and it isn't hard as you can see
7:06
here to get inside that minimum Focus
7:08
distance if I started with that uh the
7:11
you know decorative ball hanging on the
7:13
tree and you can see I I don't have to
7:15
move too close before I'm completely
7:18
past minimum focus on that and so not a
7:21
high degree of magnification on a
7:23
positive note however it does come with
7:25
a nice case and for the money this is a
7:28
very nice lends it's nicely made it
7:31
handles well it is a great package for
7:34
the money now on the autofocus side of
7:37
things it is equipped with an STM or a
7:39
stepping Focus motor again probably
7:41
similar to what we saw in the recent
7:43
Aurora 885mm f1.4 in my focus PS test
7:47
overall I saw good results there there's
7:49
smooth and confident transitions from
7:52
one Focus point to another from A to B I
7:55
felt like it was pretty well damped
7:56
which is important in a lens like this
7:58
so it still has a
7:59
Cinema cinematic feel to it though
8:02
probably again doing a manual pull is
8:04
going to give you the most cinematic
8:05
feel to it uh but in this situation
8:08
because it's a long Focus throw you can
8:10
actually get a pretty well damped pull
8:12
from one to another hand test also went
8:15
well and you can see that it
8:17
transitioned from my hand to my eye good
8:20
I found that it was improved after a
8:22
firmware update and so that just
8:24
stabilized autofocus a little bit more
8:26
now you may have noticed that there is
8:27
some Focus breathing there it's not
8:29
super high but it there's enough there
8:32
that I did notice it in some of my shots
8:34
and so just be aware of that I'll
8:37
reserve some of the other Focus
8:38
observations for when I show you the
8:40
short film in just a few minutes and
8:43
we'll dive into that in the image
8:44
quality section so as noted I found that
8:47
this lens really basically covered the
8:50
fullframe image Circle there is a little
8:52
bit of heavier vignette in the corners
8:55
that is really kind of due to Mechanical
8:57
vignette but it's not true mechanical
8:59
cenia and you can correct for it and
9:02
it's just very minimal there in the
9:04
corners and what I found is that in less
9:05
extreme situations where you don't have
9:07
like snow in the corners I really didn't
9:09
notice it in overall footage in fact I
9:11
had kind of forgotten that this even was
9:13
being marketed as an S35 lens because it
9:15
very naturally just shot in full frame
9:17
on either my A7 R5 or Alpha 1 and I
9:21
found that even when I shot Stills and I
9:23
dived into the corners I found that
9:26
there it's it's resolving all the way
9:28
into the corners except for maybe like
9:30
the last 1% or so and while there is
9:33
some pretty obvious lateral chromatic
9:36
aberration there uh for Stills they're
9:38
pretty easily correctable and frankly I
9:40
didn't really notice them as much for
9:42
video work and so not really any kind of
9:45
major problem in terms of the normal
9:47
fringing um I didn't find that that
9:49
fringing was really all that pronounced
9:51
as well I also found that relative to
9:55
the 35mm 1.66 times anamorphic lens from
9:59
I that I tested a year and a half or so
10:01
ago I found that that lens had a lot of
10:03
distortion I didn't really see any
10:04
Distortion with this lens so that's
10:06
great nothing more really to correct
10:08
there this is the Blue Streak version
10:10
that I'm testing and so you can see
10:11
there definitely is some Flare from this
10:14
lens some of that is intentional it is
10:16
the streaking that is desirable for kind
10:18
of C look or music videos that type of
10:21
thing but there's also some other flare
10:24
patterns there the the Coatings don't
10:26
exemple kind of exempt it from flaring
10:29
and so that is something you're going to
10:30
work out we're now going to dive into a
10:33
short film that we put together over the
10:35
holidays and just kind of documenting a
10:38
day with family and so I'll talk to you
10:41
about a few more of the optical and
10:42
autofocus properties as a part of that
10:44
just show you kind of the real thing now
10:47
one of the things that you will see from
10:49
this footage in my opinion seir Eyes
10:51
Optical glass it's not top class this is
10:53
not a ice lens but I think that the
10:55
footage overall looks good it has a very
10:57
cinematic feel to it and even without
11:00
grading as we have done here you'll find
11:02
that the overall footage looks good the
11:05
Boke has a very unique signature as we
11:07
pre previously mentioned I don't
11:09
personally love it for specular
11:10
highlights but in some of these other
11:12
shots where the shallow depth of field I
11:14
think that the quality of the boka looks
11:16
otherwise good and it's relatively soft
11:20
and smooth and while it doesn't you know
11:22
completely blur out backgrounds what's
11:24
there looks pretty decent I found that
11:27
the sharpness was good enough that we
11:28
shot
11:29
not exclusively at f1.8 but we shot
11:31
significantly at f1.8 and we got really
11:35
good results greatl looking footage in
11:37
real world use I found that actual color
11:40
fringing was fairly low I did see in
11:42
some of the shots I saw a little bit of
11:45
uh fringing sometimes around the window
11:46
panes it'll be a little bit of a blue
11:48
green look there but really it was only
11:51
there because I was looking for it and
11:53
the truth of the matter is that I see a
11:55
lot more fringing than that in similar
11:57
situations and a lot of um you know very
12:00
mainstream professional shows or movies
12:02
and so I wouldn't consider that to be
12:04
any kind of real negative quality
12:06
overall as you can see it you're just
12:08
able to produce really engaging looking
12:10
footage that does have a very cinematic
12:12
feel to it which leads me to my
12:15
conclusion a lot of this footage was
12:17
shot by my nephew Matt Ansley from
12:19
Ansley creative and uh he was able to
12:22
just pick up the camera I showed him I
12:24
said look what I've got he grabbed it
12:26
and he started foot shooting and he was
12:28
able to get the footage that's shown in
12:30
this short film just from a few hours of
12:32
casual shooting and that really shows
12:35
the the strength of this particular lens
12:37
never before has there been an option to
12:39
get this kind of footage with just a
12:40
camera and a lens you don't have to have
12:42
any kind of focus follow equipment and
12:45
you know based on the the fact that most
12:47
modern cameras have inbody image St
12:49
stabilization I didn't have there was no
12:51
stabilization equipment being used here
12:53
just a camera and a lens and yet you
12:56
could put together something with
12:58
relatively little work that you know
13:00
comes across as being a credible little
13:02
short film here and obviously if we were
13:04
shooting with more Dynamic you know
13:06
lighting and atmospheric conditions you
13:08
could produce something that would be
13:09
even more movie like in its overall
13:12
performance the price is reasonable and
13:15
if you don't mind doing a little bit of
13:16
postwork to desqueeze your footage I
13:19
would say that pretty much anyone can
13:20
get very cinematic video and if you
13:22
don't know how to desqueeze footage
13:25
there's a lot of tutorials out there
13:27
that will tell you how to do it pretty
13:28
simply simply I suspect that this
13:31
probably won't be the last lens of its
13:33
kind probably not even the last that
13:34
we'll see from sirai because I think
13:36
that there certainly is a market of
13:38
people that are interested in doing cine
13:40
work and are interested in anamorphic
13:42
style look but they're not really ready
13:44
to invest in all kinds of equipment to
13:46
do manual focus pulls and to do Focus
13:49
follow and things like that and so this
13:51
really enables even amateurs to pick it
13:55
up run with it and have a lot of fun and
13:58
get some great footage in the process
14:00
and for that reason I think that there
14:02
are going to be a lot of people that are
14:03
interested in sir's new uh anamorphic
14:06
autofocusing 1.33 times 40 mm t t 1.8
14:11
lens if you want more information you
14:13
can look at my full text review that is
14:15
linked in the description down below
14:17
there's some buying links there as well
14:19
if you'd like to purchase one for
14:20
yourself as always thanks for watching
14:22
have a great day and let the light in
