This is the first lens I bought
which does not support image stabilization
Tamron 70-180 F2.8
The highly anticipated lens
can finally be reviewed by us here in Australia.
See, we have super power called rich
Today, let's talk about this lens
Everyone cares about to the quality of images
and how's it looks like without image stabilization
Besides
I'll give some demonstration of the macro feature
Welcome to this episode of Colorbee Photography
I'm Brian
Each manufacturer brand
has their own zoom lens series
And can be classified to f2.8 zoom lens series and f4 zoom lens series
based on quanlity and price
Finally Tamron's budget zoom lens series
come out now
Photographers who need F2.8 zoom lens series are people like us
who are rich and don't care of weight
plus those who are professional
Amateur users of F4 zoom lens series
generally don't have special consideration for the environment
So this time
Tamron find a new way
focusing on the price-performance ratio
Published a series of zoom lens,
with a good balance of image quality, size, and price
Basically, the order of the announcements of these lenses
showing the importance of them
The very first Mid-range len
2875
was announced two years ago
It is no doubt that
this lens is the most general one in this series
Basically, this special lens series from Tamron
for Sony E mount has been accepted by consumers
by their image quality and price
One year later
Tamron released another wide-angle lens mainly for landscape and video
the Tamron 17-28
On the other hand
this telephoto lens was the last one be announced.
Although the telephoto lens is interesting
they are not that useful
I know,
but why we have so much 70-200!!!
Let's talk about the overview of this lens
The first impression of it is small and light
It has only 815 gram
Compare to the gm 70-200,
which is has 1.4 kg
It almost has only half of the weight
What's more
The size gap between this lens and others 70200 2.8
is just like the gap between me and nicholas
The camera body with a Tamron budget zoom lens installed
can be easily put into a 10L Peak Design backpack
To be compact,
this lens
has three special design
First of all, is the 67mm lens diameter
Secondly is the focal length at the telephoto end is 180mm
not general 200 mm
Last but not least, it's a external zoom lens
Let's see
if these three compromises for compact design
have any effects on the performance
The 67mm diameter is a universal diameter
for the Tamron mirrorless camera lens.
All lenses were designed with the 67 mm diameter
no matter it's a fixed lens or a budget zoom lenses
For me, the small diameter design
not only keeps the lens be compact
but most importantly
I don't need lots of different filters for each diameter
You can't imagine
how annoying it is
like UV, ND, and polarization filters
for different lenses
To be honest
the 67 mm design
does not affect the image quality for earlier 1728 and 2875
a lot
But for the telephoto lens
especially the f2.8 big aperture
The small diameter
has a certain effect on the edge image quality
Actually, you don't need to worry about
the central image quality of this lens
The sharpness is quite good
in Tamron productions
It can easily fulfill the 61MP resolution
from sony a7r4
But when you are shoting with the full aperture
the edge image quality will be affected a little bit
Of course
when you decrease the aperture to f5.6
it can reach the best image quality
If you are using the APS-C camera
like a6400
or the a73 with lower 24MP resolution
This lens can easily fulfill the camera body
with no problem
Compare to other 200mm lenses
this lens has only 180mm diameter as the telephoto end
Someone worries about the difference between this 20mm
might cause some loss of the size
when shooting close objects
But testing with other 200mm lenses
including Sony GM 70200
There are no obvious differences
between 200mm and 180mm end with focusing on infinity
To shrink the size of this lens
it used a technology called external focus
About what it is
please check our last video
about cannon rf 70200
We explained what external and internal focus is
from different perspectives
So, how about this external focus
you guys might worry about
the ability of dust and water-resistant
This lens from Tamron does have dust and water resistant design
When we were using his brother, 2875
and 1728 in this one or two years
We didn't see any issue
in the extreme weather situation.
Personally,
I think this lens can still keep the quality
which means it has good resistance for dust and water
But remember
this is a telephoto lens
it has a huge piston effect when you zoom
Try your best to avoid zoom in a dusty environment
With the design of small diameter filter
external zoom
and 180mm at the telephoto end.
This lens set a flag
which is the smallest lens of telephoto f2.8 lenses
As a telephoto zoom lens
we all care about the optical stabilization
Typically,
telephoto lens with no image stablization is ridiculus
Like the old cannon F2.8 and F4 70-200 without IS
has only survived for one generation
This time
Tamron didn't add the IS feature
in this telephoto lens
I think they totally trust
the Sony IBIS can deal with it
But after our test
In the 180mm telephoto end
It does works in 1/30 s shutter speed
with an 80% success rate
But if you are shooting with 1/15 s shutter speed
This rate dropped under 50%
which is not usable basically
Compare to GM 70200, which has the IS
and that 70200 F4
This shutter speed is faster than them by 1 stop
Speaking about the video ability of this lens
The most important thins are no more than following three-point
Autofocusing, image stabilization, and breathing effect
About the Autofocusing
The Tamron newly developed motor VXD that delivers quiet and stable focusing
Nearly hard to hear any noise while the motor is working
After enable face detection
the stability is also quite good
Thanks for the Sony powerful autofocusing system
everything is quick and precise
But for the quick-moving object
it still hard to follow the focus
It might be better working on a9
IS works better than my excepted
It's hard to tell the difference
between Sony G70200 with IS and this lens
All of them need to be used with Monopod
Compare to z70200 with 3-Axis stabilization
and the RF70200 who reach the 5.5 stops IS with the lens itself
I think the fault is because the E mount
is too small
The breathing effect has been controlled in a good level
considering the compact of this lens
There are no obvious zoom-look feeling
No matter it is in the 70mm or the 200 ends
For the video user
this is very fridendly
The telephoto lenseshave two basic usages
when shooting videos
The first one
is taking close up scenes
Since the special structure
telephoto lenses have a wonderful resolution
For the close-up scenes
they can provide the perfect detail
What's more, compare to the normal zoom lens
telephoto lenses can get a better bokeh result
Do you know what're the three key factors of bokeh?
Let me introduce them
Focal length, object distance, and aperture size
Generally, we use a big aperture lens
can achieve a good bokeh effect
But the other two factors are more important
When using the same aperture value,
200mm or 24mm can achieve a better bokeh effect?
200mm
You see, longer focal length
better bokeh
Then, the object distance means more your close to the focal plane
the better bokeh you get
That's why macro lenses have only f16 or f18 aperture
but still can produce a perfect bokeh effect
So, this Tamron f2.8 big aperture telephoto lens
can give a good bokeh looking when shooting the video
It's quite helpful for improving the impressions of your scene
Telephoto lenses have another usage
which produces a good Lens Compression
A brief explanation of the telephoto lens compression
When our eyes see an objects
they appear smaller when it moves farther away
But the telephoto lens
can make the object
appears to be big even it is far away.
That's why my face looks so giant in your pictures
Telephoto lens also can
shrink the gap between different elements
This special perspective is lovely
It can show the relationship between the foreground, background, and the main object
Balance those elements
Show more details in the image
This telephoto lens from Tamron
has a super macro feature
which is amazing
It can take photos for jewelry, whether you believe it or not.
The standard macro feature of this lens
is around 85cm
In all 70200 telephoto lens
it's not too far or too close
But this Tamron lens
if you keep the focal length in 70mm
switch to manual focus mode
keep turn the focus ring
then you'll see a new world
It's close-up range down to 27cm
This can give a close-up shoot for jewelry
This is even better than those mid-range lenses
with macro features
This gives you much help when you are traveling
and needs some macro photography
Like shooting foods
or some small objects
The good thing is that the mid-range lens can give you a normal view
When you are shooting in macro mode
the image of full f2.8 aperture
is a little bit soft
I recommend you decrease the aperture value
because of sevaral reasons.
f2.8 big aperture result in too shallow depth of field when you are shooting macro
which is not good for your image quality
Besides
decrease aperture to f8 or f16
can produce an excellent depth of field
and increase the sharpness at the sametime.
Who is the target of this lens
If you daily take photos outside
and have a certain demand for portrait
I think this lens is good for you
Since it has an invariant f2.8 big aperture which offers a shallow depth of field
This is a good point
On the other hand, this lens with the IBIS
can deal with the most situation
in normal light conditions
If you are a traveler
who needs a telephoto lens
and extremely cares about the weight
I think you can also consider this one
For the price of this lens
It just released now in Australia
with the price around 2399 AUD
Because of the exchange rate
It's slightly expensive in Australia
But if you are using Chinese Yuan
or US Dollar
I just want to say, shut up and take my money
All right, today we share our review of this
whole new Tamron 70 180 telephoto lens
