For example, the most famous ones are of course Nikon and Canon.

Now emerging brands such as Sony

Matsushita Co., Ltd.

Samsung and so on. ~ the second is the brand of the existing lens of the camera.

The influence of lens on the quality of photos is mostly left.

The fuselage only affects the function, operability, photosensitive elements and so on.

Everything else depends on the quality of the lens.

However, most of these points apply to emerging brands.

1) Sony-carl zeiss carl zeiss (Germany) 2) Panasonic-Leica-Leica (Germany) 3) Samsung-Schneider Schneider (Germany) is the same as above.

Panasonic used Leica to make thousands of cameras.

And the brand is aristocratic, and you can afford it first.

You can know that you have confidence in your own quality by bidding boldly ~ And Sony is famous for adopting carl zeiss.

It is also useful in Nokia phones.

There used to be too little information on the internet.

The most mirror-like lens in the world

Leica has two, ranking second and fourth.

And Zeiss also won the third place ~ As for Schneider used by Samsung, it may not be famous.

But it will always be a German lens.

So there is quality assurance.

Loser is not a Japanese brand.

Plus inexperience ~ third

Aperture value of eye lens

The lens usually lists "1: 2.8-4.9" or "F/2.8-4.9". The finer the value, the larger the aperture.

The aperture value indicates the amount of light entering the lens.

The higher the light input.

When shooting in a dark environment, it can still be attached to the safety shutter.

This way, the photos will not be affected by the slow shutter and hand shake.

Such as S90, S95, LX3, LX5, EX 1 and other large aperture DC.

Famous for shooting at night ~ need to shoot the fourth kind of lens.

At present DC is divided into periscope and telescope.

Periscope type, such as Sony's T and TX systems.

Olympus has both Mjutouch and others.

The lens will not get longer or shorter.

Located in the upper right corner of the fuselage.

Poor optical quality

The zoom factor is limited.

But the advantage is that it is light and easy to carry ~ the telescope head is easier to understand.

For example, all models of Canon.

All use telescope heads.

After starting the machine

The lens will lengthen.

The farther you zoom.

The longer the lens.

Better optical quality

Zoom multiples range from 2.5 times to 35 times.

The aperture value can also be larger.

But because it is scalable,

So it is inconvenient to carry and use.

Even be careful that the lens will collide if it is too long ~ The fifth camera not only shows the ISO value and high ISO noise control ability.

ISO refers to the sensitivity of photosensitive elements.

The higher the ISO value.

The higher the sensitivity.

The highest ISO 102 at present.

800 is usually shot in the sun with the lowest ISO.

So as to obtain better quality.

At present, the emphasis is on high ISO and low light shooting scenes.

Push up the ISO value of night shooting.

The advantage is that you can get the picture without washing the big aperture.

But at the same time, high ISO will bring noise.

Let the photo have a little impurity.

The average person may accept it

But friends who make friends with each other will be very annoying.

Noise control ability refers to the camera's ability to eliminate noise.

This way, the photos will not be completely affected by noise.

However, elimination may also lead to the loss of some details.

Maybe the original lines will melt to the left like ink.

Therefore, the film friends will not set the ISO too high, but will try to slow down the shutter ~ the operation key on the sixth camera.

In a SLR camera

The flagship series is the most operable.

Almost every variable has a button.

Let you keep entering the interface.

You can adjust it first.

Such as ISO, aperture, EV, shutter, shooting mode, etc.

The more camera buttons.

The volume and weight may become larger.

But the system becomes more user-friendly.

The operation can be faster.

I don't want you to miss the shooting opportunity because of variable adjustment.

How many buttons are buttoned or broken?

I'm glad you need this camera ~ Seventh

In fact, every camera has a photosensitive element.

Used to perceive light

And then converted into an image.

Divided into CCD and CMOS.

The main differences between the two are: CCD has higher quality, stronger color, overheated shooting for a long time, high manufacturing cost and extremely high power consumption. Compared with CCD, CMOS has lower quality, lower power consumption and lower manufacturing cost (indirectly reducing camera price). However, many people have begun to pay attention to this field ~ eighth.

White balance performance

The color temperature of white balance system is different in different environments.

It may be a housing company.

The environment is orange.

You choose the tungsten lamp white balance on the left.

While the image shows a normal color temperature.

The white balance of the camera is ideal.

Because the color temperature is wrong

The color of the photo will also be affected.

It's like day now. You use "tungsten lamp"

The final photo will become very blue and white.

Many colors have no sunshine! ! Therefore, white balance is not just about choosing the ninth shutter speed, which is very important for performance and performance.

The shutter speed of ordinary DC may be11500 to 3 seconds.

But when the aperture is large and the shutter is limited

The environment is so bright

Zhang Xiang may have sunburned for nothing.

Wu Ye

The faster the shutter is.

The darker the picture will be.

So when the ambient light

The shutter will be faster than1100 second.

But when the environment is at night

When it's dark

The shutter speed may change back to 1/4 to 2 seconds.

The shutter is too slow.

The image will be strongly affected by hand shake ~ the shutter speed of an entry-level SLR is about 1/4000 to 30 seconds, one tenth.

The shockproof system may have an impact on your choice of camera.

Many people play with cameras at present.

But everyone is afraid of hand shock and has been asking this department how to prevent earthquakes.

How about shockproof fruit?

In fact, the earthquake-proof system is not omnipotent.

Just move the lens or photosensitive element to match your hand shock.

Let the image not be too strong.

At present, the strongest thing is to go to level 5 earthquake prevention.

The wide-angle safety shutter is about 1/2 seconds.

The safety shutter of telephoto end is about 1/20 seconds.

Under the safety shutters.

Hand shock will have a good effect ~ eleventh wide angle

I often take pictures of the scenery when the photos are good.

But if the image contains a wide range, the scenery will depend on the ultra-wide angle.

28MM is a normal wide angle.

24MM is the widest ultra-wide angle at present.

It's more important to take pictures of the film group! !

Evaluating a camera mainly depends on the user's main purpose. For example, users often carry a four-dimensional camera and need to use it outdoors, so it is best to choose a three-proof camera. If you just take a snapshot, you should choose to turn on the focus quickly and unobtrusively. Travel should be light and have a wide mirror; Night shooting ability is not bad; Shoot a good dc. The main question is how to use it before considering the price. Pixels are the least considered, because 8 million images are enough; Now, no camera has less than 8 million images.

Hello, I recommend a website for you, a website for evaluating the latest product prices and products of mobile phones and photographic equipment, which contains many practical tips and common sense. I hope the digital price is useful to you.
