Hi Everyone. Thanks watching Color Bee photography life magazine. I'm Brian
Today we just talking about one thing: 50mm prime lense
Why we choose 50mm focal?
How to choose the right 50mm lens for your own
And how to use 50mm lense
I hope you can find the answer from this episode

The reason why the 50mm lens is classic is determined by its characteristics.
First of all, the structure is mature, normally large aperture, it has a very natural perspective
Most lenses use the Planar optical structure
This optical structure was finalized in 1896.
Due to this is 5 group 6 elements simplicity of production and low price
Became one of the "standard" lenses of the early 135 film camera of the time.
Compared to the 35mm which its viewing angle is close to the full view of human eyes
and 85mm narrow-angle of view is equivalent to the human eye
Shooting portraits and close-up stills, etc., make the audience feel focused but not as cramped and space-compressed as the 85mm lens
If used for street photography or daily use. the picture has content but not like 35 wide angles easy background mess
Peace and nature are my understanding of this lens,
But in the other word is mediocre. it taste like insipid water. nothing exciting from this lense
you must be extremely sensitive to light and composition to capture the most exciting picture
So, if you have already bought 50mm, how to use 50mm, TWO advises.
Either the pull up the aperture, the advantages of prime lense Bokeh.
Either set it on f8, fully use the sharpness of the lens to blow up the mind
The maximum aperture shot, try to find a low contrast light than mid-day sunlight. do not shoot portraits under the sun, prevent overexposure, prevent dispersion
Then find a deep and clean background, fully blur the background
One trick for whole life :D
The small aperture is taken to control the dispersion after the lens aperture is smaller, and to increase the depth of field range so that the image with higher sharpness can be obtained.
This time you can use this technique to shoot Take pictures of textured objects such as street walls, plants, animals and even portraits.
And use a certain angle of light to emphasize this texture,
One of the biggest advantages of the 50mm lens is that the price is abundant, and it can meet the various consumption levels of the budget beginner or someone not care about money
It's not like 35mm, it's a penny, and spending a little less makes you feel that the picture quality is not enough.
In 35mm must buy f1.4 otherwise you couldn't feel depth of field
But the most of 50mm lens has good picture quality.
So for new photographers, it is easy to find a set of camera and lense, let you learn photography and play photography.
Then the problem is coming, Each brand in the market has its own 50mm prime
the price from the cheapest $150 up to $13000! it is 100 time greater in price!
Where are the differences between them? If you want to buy 50mm, which one is right for you? We are close to telling you today, where is the money spent?
In fact, the large-scale production and manual assembly of the assembly line, who is expensive and very obvious, but whose quality is more mature and stable, it is hard to say.
​Don't look at this small lens of Canon, you can still achieve the accuracy of the lens glass is equivalent to a 2 mm error on a football field.
5 lenses, 5 photos, let's talk with the results. Because it is blind test, I don't know which photo was taken. The tester labels the 5 lenses by 1, 2, 3, 4, and 5 respectively.
So whether it's $150 Canon, or the $6,000 Leica 50 summilux, on this test platform, it's just a digital symbol.
We have tested three groups of environments, including indoor still-life with background lights, indoor natural light portraits and outdoor glare backlights.
We take a rational look at these lenses from the sharpness, dispersion control, out-of-focus performance and anti-glare performance of the lens.
In the optical performance test, we open the aperture of each lens to the maximum, which is a big test for the sharpness and dispersion of the lens.
Immediately we found the sharpness of the 4th lens, which stood out from all the shots.
The purple fringe is almost invisible, and the spot outside the background is substantially circular, without the appearance of a lemon-shaped aperture.
The spot can see that the aperture blade is not circular, but does not affect the dispersion of the background. The whole photo is solid and the contrast is very good.
The sharpness is second only to No. 4, which is the No. 1 lens. The lens sharpness is almost as good as the No. 4 head, but the dispersion is more serious.
The background spot is also basically circular, but the obvious onion ring is visible to the naked eye, which is one of the disadvantages of the aspherical
The sharpness of No. 2 and No. 3 is basically the same, and some purple fringes are also there, and the astigmatism that appears is also present.
The biggest difference between No. 2 and No. 3 is the performance outside the coke. The No. 3 focal light class center is very real, and there is no image of the onion ring at all, and the edges are naturally diffused. It is the most comfortable of the light classes in these lenses.
In contrast, the light shift of the No. 2 lens is trivial, the background is Bokeh, but it feels chaotic.
The bokeh is most comfortable to count the No. 5 lens. Although the sharpness of the No. 5 lens is different, the aperture outside the focus is very uniform and natural.
And the 5th lens is not very sharp, but the dispersion is very well controlled. The contrast of the 5th lens is also low in these lenses.
The first set of photos, the No. 4 lens wins, the No. 1 lens second, the No. 3 lens has no obvious shortcomings, the No. 5 win is well controlled in dispersion, and the No. 2 lens is the worst.
In the second set of photos, the indoor portrait challenge is sharpness and dispersion.
Still the No. 4 lens wins, the focus will be inevitable, there is almost no dispersion in the highlights, and the contrast of the whole photo is very good.
The 5th lens also has almost no dispersion, but the sharpness and the overall contrast are a lot worse than the previous 4th lens, which can be improved by post processing.
Due to the retreat of the No. 3 lens, the competition of "Dispersion King" was exhibited before the No. 1 and No. 2 shots, and the competition was very intense, regardless of the top and bottom.
It’s just that the sharpness of the No. 2 lens seems to be slightly worse. No accident should be the worst of these lenses
The third set of photos we tested was extremely extreme, shooting large backlit leaves at noon. This is a test of the lens coating and even the glass material.
No. 4 lens still has no suspense to win, this can still show the light and dark details under the big light ratio, and magically does not appear dispersion
The sharpness of the 5th lens is not flattering, but the purple fringe and glare control are really good, and the picture looks very natural.
In contrast, the purple edge of the No. 1 lens exploded. The 2nd lens I think is lost in the entire mirror glass material and coating quality, all the details under the strong light are lost.
No. 1 : Sony 55/1.8 No. 2: Canon 50mm 1.8 No. 3: Zeiss 50f2 Macro 4th: Sony 50 1.4 5th: Leica 50 1.4 APH
