Hello everyone
Im your professor Ma
Many people feel that after buying a mirrorless camera ™
they do not
use it smoothly or do not reach the expected level
a large part of
the reason is not the camera
but your settings have problems
In this programme you will learn
what the focus modes
focus areas and
focus settings in
the Sony menu
mean and how they differ
and how to choose them in real life
I hope you can take out your cameras
and work with me
Students who dont have a
camera can collect it first
First of all remind Xiaobais friend
Press the shutter button
halfway to start autofocus
When the camera finishes autofocusing
a green frame appears
at the focus position
Press it again to start shooting
Let me take this Sony A7M3 as an example
and first enter the first major shooting settings
Lets start with the focus
mode in
the AF 1
AFS stands for single focus
When you press the focus button
the camera will try to focus automatically
When the focus point is fixed
the camera will focus only once
It is suitable for still life shooting
AFC stands
for Continuous Focus
The camera keeps trying to focus
during the half press of the shutter button
Perfect for shooting objects in motion
Afa is
the autofocus mode
Halfpressing the shutter will automatically judge whether
the object is moving
If the object is stationary
the focus position is fixed
and if the object is moving
the focus is continuous
which is theoretically applicable to all cases
But AFa I dont recommend
because youre smarter than the camera
The next item direct manual focuse of DMF
completes automatic focuse
once and then switches to manual focusing
Useful for shooting
macro scenes or when very precise focusing
is required
Finally
MF means manual focusing by turning the focusing ring

Next is the most important focus area settings
The wide area camera of
the first focus area will automatically find the subject
as the reference in all focus
areas for automatic focusing
Can be directly understood as a fully automatic focus
by the camera to
decide which area to focus
on the main body
The advantage is that you dont have to move the focus point
The disadvantage is that the camera may choose the wrong subject to focus
This focus area I
only recommend beginners to use the second area
can be understood as
a miniature version of the wide focus area
we can use the rocker or button to move the area this focus area
The camera will autofocus
only in this area
In the area
the subject is also determined by the camera
This focus mode is ideal for shooting
interviewing or following large subject
The third middle as its name implies is
to focus automatically on the subject near the center
of the display screen
this focus area is often used when I
need to center the composition
of the video
shooting VLOG is also very good to use
you only need to point the lens at the main bodyNext
the camera will complete the automatic focus
The fourth free point free
point is to limit the autofocus area to this small box
we need to move
the focus box to the
desired focus position
when we select the interface in the focus area
You can also switch left and right to change
the area size of the free point
This focus mode is the one I think is
the best to use and the one I use most
Because its entirely up
to me to decide where to focus
This focus mode is recommended for fast hands
Because the disadvantage of
free points is that you
need to constantly operate the camera to
move the focus point
When you find it difficult to focus the camera
you can choose one that is on the
same plane as the main body
but with a higher contrast
Focus on the point where the color contrast is greater
5thExpand Free Point Expanded
free points can be understood
as automatically expanded free point
When you cant focus on
the point in the focus frame
The camera automatically uses the surrounding focus area
to focus
I usually use this mode when I shoot on the street
because I need to
constantly adjust the position
of the focus frame
Sometimes it will inevitably fall on the main
body a little bit
Expand free pointsIts good to help me solve this problem
The last focus mode
Lock AF Mean that at afc
That is to say
it can only be turned on in the continuous focus mode
Lock AF The meaning of is actually very easy to understand
First you select the
focus area you want to use
Then halfpress the shutter to focus on the subject
The camera will track the subject from
the selected AF area
If the object that is locked in focus moves on its own
Then the focus point will automatically chase the
object for continuous focusing
This mode is
usually used for shooting moving objects
Of course in addition to the
focus mode
and focus area
there are several small focus settings
that you must know
Using the camera
will be easier with the right adjustment
Now lets go back to AF 1 in the menu
First of all AFS priority and AFC priority
mean focus
priority or shutter release priority
in single focus
and continuous focus
Basically you have to choose between
getting it or getting it clear
The AF tracking sensitivity can
be understood as the
sensitivity of switching the focusing target
and when the value of the AF tracking sensitivity is set higher
The more sensitive it is to automatically switch
to the new focus point
For example when shooting a
scene in which the
focusing subject is obscured in the crowd
the value is
generally lowered
O that the focus doesnt suddenly switch to the new occluder
Then the last important setting is the
video shooting setting of the second item
The AF drive speed refers to the
time of refocusing after
the focus point is changed
When the driving speed is adjusted to high speed
the refocusing time is fast and the focus point can be switched quickly
But I usually set the value to the
lowest when I shoot short videos
Because its more natural
to automatically switch the focus

Finally a little surprise for you
to share my camera (a 7 M 3) shortcut settings
in this set of
shortcut keys I rarely enter the menu to adjust
Greatly improved my shooting efficiency
All my shortcut settings will also
be on the screen
Want to refer to the small partners
can be directly screenshot slowly set
