5d2 7d which one to buy Specific problems and problem specific analysis

These two machines are about the same,5D2 is full-frame,The picture will be broader,But it doesn't come with a flash,It's not very convenient,And 5D3 is out,And 7Dbasically no price reduction in a year。

Novices want to sell professional-grade cameras, optimistic about Nikon D90, D300, Canon 5D2, 7D, 50D, which one to buy, what head, and want to get a 120 camera in the future. .

It's definitely 5d2. 7D is not comparable to 5D2, 60D is even more incomparable, and 5D2 is full-frame.

I think it's about the same, I also want to go to 7D, and the money I save is equipped with a 24 70 head, and the image is absolutely handsome.

As for Canon SLR 7D and 5DII, of course I choose 5DII. The full outfit is really important.

In terms of image quality, the whole set has a high degree of latitude and a smaller noise base.

In terms of filming, the full set can provide higher resolution and can produce larger**.

Single-lens reflex framing cameras, also known as single-lens reflex cameras. It refers to a camera that uses a single lens, through which the light hits the mirror, and the light is viewed through the reflex.

The so-called "single lens" means that the photographic light path and the framing light path share a lens, unlike the rangefinder camera or double reflex camera with independent lenses for the framing light path. "Reflective" means that a flat mirror in the camera separates the two optical paths: the mirror falls down during framing, reflecting the light from the lens to the pentaprism and then to the viewfinder window; When shooting, the mirror is quickly raised, and the light can hit the film or the image sensor CMOS or CCD.

As can be seen in the construction diagram of the single-lens reflex camera, the light through the lens reaches the reflector, and then reflects to the upper focusing screen and forms an image, through the eyepiece and the pentaprism, we can see the outside scene in the viewing window. The light passes through the lens and is reflected by the reflector into the frosted viewfinder screen.

Through a convex lens and reflected in a pentaprism, the final image appears in the frame. When the shutter is pressed, the mirror moves in the direction indicated by the arrow, the mirror is lifted, and the image is captured on the CCD, as seen on the viewfinder screen.

The advantage of DSLRs over rangefinders is that what you see is what you get, and the angle of the image in the viewfinder is the same as the angle at which the final film is produced. But compared to the rangefinder camera.

The rear focus of the SLR camera lens should be able to image at the position of the reflector and the focal plane position of the image sensor at the same time, and a false focus must be generated before the imaging focus is flat and pure surface, which causes the structure of the optical lens of the SLR camera to be more complex and larger, and the imaging effect is not as direct and transparent as the rangefinder camera. At the same time, the volume of the "reflector" should be thick and bulky.

Without any in-depth reviews, Canon's EOS 6D Mark II is better than the EOS 7D Mark II in most cases. If you can't tell the difference between the two, you can choose EOS 6DMark II directly.

As far as their own home machine is of course 6d2

The 7D2 is a professional sports bird shooting machine.

Two cameras for different purposes, the 7D2 is a high-speed camera, fast focusing, fast continuous shooting, but the high-sensitivity performance is average, suitable for shooting sports and birds. The 6D image quality is good, full-frame, with more details, and the performance is better in low light, which is suitable for ordinary shooting.

Since its establishment in 1937, Canon is a global leading integrated group that manufactures imaging and information products, and has globalized and expanded its business to various fields over the years.

Canon's product lineup is distributed in three main areas: personal products, office equipment and industrial equipment, and its main products include cameras and lenses, digital cameras, printers, copiers, fax machines, scanners, broadcasting equipment, medical equipment and semiconductor production equipment.

Headquartered in Tokyo, Japan, Canon has four regional sales headquarters in the Americas, Europe, Asia and Japan, and has 200 subsidiaries around the world and employs more than 100,000 people. On March 9, 2016, Japan's Toshiba Corporation held a board meeting today and finally decided to give its Toshiba Medical System Corporation** to Canon Inc., which proposed an acquisition of 700 billion yen (about 40.5 billion yuan).

First of all, from the point of view of positioning.

The 7D2 is the flagship sports camera in APS-C format, from high-speed continuous shooting to 65-point full cross focus, as well as a variety of new features. It can be said that 7D2 does not lose 5D3 except for the frame. （ps：

I personally tested it in the physical store, 7D2 does not turn on noise reduction RAW to JPG high-sensitivity ISO6400 is available, which is almost a notch lower than 5D3)

The 6D belongs to the 135 full-frame entry-level home machine. Slow continuous shooting, poor focus, a single SD card slot, and 1 4000 shutter speeds all mean it's an entry-level product,** pretty much because of the full-frame CMOS. A little is wifi again, high sense of strong (stronger than 5d3).

If you insist on a 24-70 lens or 6D, because the focal length of the lens is multiplied by the coefficient of the Canon APS-C frame, that is, 24-70 on 6D is 24-70, and on 7D2 his focal length becomes 38-112. In other words, if you shoot landscapes, 24-70 doesn't have a wide angle on 7d2.

So here are the options for you. If you're going to sell 24-70 f, you're going to have a bigger budget.

1) If 6d go directly to 24-70.

2) If it is 7d2, then it is recommended to match 15-85 and a Sigma 50mm F art. (These two lenses together are not as expensive as 24-70) zoom tours. Pat the scenery, and the fixed focus is used to pat the child.

Judging from the news from Hummingbird.com, 6D is about to be discontinued (it is said that Canon will release 6D2 in 2015). Although 6D may be a little more suitable for your needs (because of home), I still recommend you to buy 7D2. After all7D2The picture quality is not bad, the picture quality is slightly inferior6D, but the body performance is strong.

If you're going to go on a high-end 1D series in the future, then choose 7D2! After all, 7D2 is a good standby, which is very good for capturing the sports series and the crazy bear child, and the light is OK in the case of 5D4, because it is C format ultra-long-distance bird hunting is better than 5D4, the disadvantage is that 7D2 high sensitivity is poor, and the dark light performance is relatively poor (post-production is required). As for the 6D series, it is more amateur, if you just usually shoot and play, it's okay, 6D can't fully play the high-end lens effects such as the 24-70 second generation and the 16-35 third generation, and the quality of the film is generally recommended to give up.

If you are only ready to buy a single machine, it is recommended to go directly to 5D4, Canon SLR has been reducing prices in recent months, and the new machine will come out after the 6D series and 5D3 will definitely dive in price, only 5D4** can be slightly stable for a while.

Of course, it's 6D good, full-frame, night scenes can also shoot high-quality **, of course, 6D's focusing system is a bit of a chicken rib.

In terms of size, the Canon EOS 5D Mark II is a bit more powerful than the EOS 6D, and the handling is more specialized than the EOS 6D. It's not hard to understand that the EOS 5D Mark II is positioned as a quasi-professional, and the EOS 6D is positioned as an entry-level, so naturally everything is simple. But there's nothing wrong with that, the controls are simpler, the volume is lighter, and the simplicity and practicality are also in line with the preferences of most players.

In terms of focusing, the Canon EOS 5D Mark II uses a 9-point autofocus + 6-point secondary focus system. The EOS 6D features an 11-point focusing system, and the ** focus point supports focusing in low-light environments of -3EV. And Canon's top-of-the-line flagship DSLR camera, the Canon EOS 1-D X, has only reached the level of autofocus at a minimum brightness of -2EV.

Another improvement over the Canon EOS 6D is its high sensitivity, which is typically ISO 100-25600, which is the same level as the EOS 5D Mark III and a qualitative improvement over the EOS 5D Mark II's ISO 100-6400.

To sum up, although the Canon EOS 6D has 1 million fewer pixels than the EOS 5D Mark II, the high sensitivity has been improved to ISO 25600, and the high-sensitivity performance is about a notch better than the EOS 5D Mark II, which is also thanks to its DigiC 5+ image processor. The EOS 6D can also complete focusing in low-light environments, which is a certain upgrade compared to the EOS 5D Mark II's focusing system. In addition, EOS 6D has a built-in Wi-Fi module in the EOS system for the first time, allowing ordinary users to enjoy wireless transmission and remote shooting experience at a low cost.

Moreover, the Canon EOS 6D is 1000 yuan cheaper than the EOS 5D Mark II, and it is a wise choice to buy the Canon EOS 6D in these two products.

D uses a 60D button setting, eliminating the multi-function lever and replacing it with a five-dimensional button integrated with the turntable. On a full-frame SLR, the control speed is somewhat reduced, but the 11-point AF of 6D is really not so simple to switch with a five-dimensional button. In addition, the feel of the five-dimensional keys is also average, which is where the 6D and 5D series are discounted.

3. The difference between Canon 6D and 5D Mark II is that two new focus points have been added, **The performance of the focus points is basically the same, and the edges are also slotted focus points. The difference in focus between the two cameras also depends on the metering system, with 6D supporting focus in lower light. The 61-point focusing system used in the 5D Mark III, including a 41-point cross-focus, is also a rare strength in a mid-range full-frame SLR.

In fact, it's about the same,The product positioning is different,To be honest6DIt's relatively more suitable,On the one hand, the focus is better than 5D2,The image quality is also good,And it's not discontinued,**It's not expensive,The volume is very good,If you don't need it in particular6D's is very good。

6D good digital products, buy new not old.

I've used both.

In addition to the 5D2 body material is different.

Other performances are not as good as 6D

In addition to the focusing system, the invincible rabbit is really invincible. It's acceptable to its focusing system, and it's basically burned to the end when you enter the invincible rabbit.

6D, the full frame is just starting, and the good is to come.

It is recommended that 6D, 5D2 is really old, and now there are many inventory or refurbished goods on the market, and it is better to buy the former, and it will be a loss to buy the latter!

The 6D machine is also good, and it is also full-width, although the positioning is not as high as 5D3, but according to your situation, it seems to be enough!

Without an in-depth understanding of these two machines, intuitively, go for EOS6D. PS: Locate photography enthusiasts.

Full-frame DSLR camera.

What is the purpose and significance of multi-** and HDR?
