Vealtruck's AF 50 millimeters f 1.8 FE lens offers a good price to performance ratio.
The 50 millimeter focal length is versatile for various types of photography including landscapes, portraits, street, and reportage.
The lens has an f/1.8 aperture, suitable for low light shooting and achieving subject separation.
Dimensions of the lens are 88 millimeters in length and it weighs 350 grams, making it compact and lightweight.
Build quality is described as very good, solid, and premium, especially considering the price point.
The lens features a metal mount and a USB-C port for firmware updates, enhancing convenience.
There is some degree of weather sealing, although there is no gasket around the mount.
The lens has a 55 millimeter filter thread which is not the most common but still easily obtainable.
Comes with a basic plastic lens hood and a protective pouch for storage and transportation.
The focusing ring is sufficiently large with a focus-by-wire system that is smooth and has reasonable resistance.
The aperture ring operates smoothly without clicks, and can be set to allow in-camera aperture changes.
Optical testing with a 61-megapixel Sony A7R4A sensor shows very good central sharpness from f/1.8.
At f/2, contrast is very good, and by f/2.8, image quality is perfect.
Corner sharpness improves significantly at f/4 and is perfect by f/5.6 and f/8.
Vignetting is present but manageable, with a Lightroom profile available to correct it.

Transcripts
hello my friends in today's video we
will take a look at vealtruck's af 50
millimeters f 1.8 fe
wheel trunks has already released a
couple of lenses for the e-mount and
they have proved to be very valid
options
another release is the 50 millimeter f
1.8 which promises a good price to
performance ratio
in this video we will take a look at the
optical qualities at the performance of
this lens in combination with sony a7r4
and a74 and i will try to help you
decide whether you should consider
getting one
50 millimeters is a classic versatile
focal length which puts a lot of
emphasis on the subject
it is suitable for certain types of
landscapes or cdscape photography for
portraits and also for street
photography and reportage
f 1.8 makes it suitable for low light
shooting and you can definitely get a
lot of subject separation as well
it is 88 millimeters long and it weighs
350 grams
there are some smaller 50 millimeter f
1.8 out there but it definitely isn't a
big or heavy lens by any means
the build quality is very good
it feels very solid and i would even say
premium especially at this price point
the mount is metal as well of course
as you can see here there is also a usbc
port for firmware updates which is very
convenient
it has some degree of weather sealing
which is very nice at this price point
unfortunately there is no gasket around
the mount
it has a 55 millimeter filter thread
which is not the most common size but
still easy to get
the lens comes with a basic plastic lens
hood which will do the job so no
complaints here either
much like other wheelchairs af lenses it
also comes with a protective pouch which
is useful for storage and transportation
regarding the control elements there is
the focusing ring and aperture ring the
focusing ring is sufficiently large
it is a focus by wire system so it is
completely smooth but it has a
reasonable amount of resistance
manual focusing with this lens is pretty
good for a focus by wire system i was
able to do some focus pulling with no
issues
the aperture ring is smooth so it has no
clicks i would prefer operation with
clicks but it has a sufficient
resistance and it is kind of hidden so i
haven't experienced any accidental
aperture changes yet
if you don't want to use it you can set
it to a position and change the aperture
in camera
so how about the optical qualities
i have tested this lens with a 61
megapixel sensor in sony a7r 4a
this sensor is very demanding when it
comes to the optical qualities of the
lenses
the central sharpness is actually very
good right from f 1.8 but the contrast
is a little bit weak and there is
moderate amount of chromatic aberration
at f2 the contrast is already very good
at f 2.8 the image quality is basically
perfect
the image quality is basically the same
at f4 f 5.6 and f 8.
the sharpness at f 11 is still great but
there is some decrease of contrast due
to the diffraction
the corner sharpness at f 1.8 is pretty
solid as well but not great
it slightly improves at f2 and f 2.8 but
the big improvement comes at f4 where it
is very good
it further improves at f 5.6 and f 8
where it is basically perfect
f 11 looks the same as f8 so there are
no sense of diffraction in the corners
there is some vignetting but the amount
is not terrible
there is a lightroom profile for this
lens which is great and it will get rid
of the vignetting but it slightly
decreases image quality in the corners
the amount of distortion is negligible
overall i can definitely say that i'm
happy with the image quality
f 1.8 is more than good enough for low
light and blurring the background f4
offers very good sharpness across the
frame and at f8 you will get perfect
image quality even in the corners
the real world images basically reflect
the testing scene
the overall rendition is very nice with
accurate colors so i don't have any
complaints
the minimum focus distance is 55
centimeters which translates to 0.1
times magnification
these lenses aren't usually great for
semi-macro works and that applies in
this case as well the image quality at
the minimum focus distance is pretty
solid though but you will have to stop
it down for maximum sharpness
at 50 millimeters you can get a lot of
subject separation at f 1.8 this lens
has 9 aperture blades which is fine and
the bokeh is quite pleasant the
transitions between areas in focus and
autofocus are pretty smooth as well the
bokeh isn't particularly special on this
lens but there is nothing wrong with it
either so i can say that i am happy with
that
the autofocus is basically as good as
with the latest sony lenses
in stills it is very fast 100 accurate
and there is absolutely no hunting
in video it is the same thing it is also
very smooth or very fast depending on
your in-camera settings sony a74 has
great autofocus which largely
contributes to this result but overall
huge thumbs up for the autofocus
the autofocus motor is not completely
silent it definitely isn't distractingly
loud but it may be captured by an
in-camera microphone
shotgun microphone should be fine
depending on the sensitivity
there is some amount of focus breathing
but it isn't too bad
i think that the focus pulls in video
look good even when you are focusing at
a close distance
if you are wondering about a7 force
focus breathing compensation function
that is not available with this lens
af 50 millimeter is not stabilized which
is to be expected with this type of lens
the inbound image stabilization in a74
or a7 r4 is sufficient at this focal
length
50 millimeter lens will probably mostly
be used for static shots in video and
that looks fine
normal camera pointing is also fine
to sum up vealtruck's af 50 millimeters
f 1.8 fe is a very solid prime lens with
great price to performance ratio
50 millimeter f 1.8 is a fairly
versatile type of lens and a worthy
addition to the lens kit of most users
optic lid is very good
i wouldn't hesitate at all to use it
even on a 61 megapixel a7r4
f 1.8 is more than sufficient for
blurring the background and you will get
excellent image quality across the frame
from f4
the build quality is actually quite
premium
the autofocus works just as well as with
the latest first party sony lenses
i also appreciate the aperture ring
despite that it has no clicks
the only disadvantages that i found are
the lack of weather sealing a gasket
around the mount and not completely
silent autofocus
other than that i can't really complain
about anything especially not at this
price point
it is a great choice for those who want
a budget friendly 50 millimeter f 1.8
i do use this lens as a part of my
personal lens kit so i can highly
recommend it
so that's it for this video thank you
