What does micro-single dog head mean?

Question 1: What does the dog head of SLR camera mean? The dog's head refers to the bad lens.

Question 2: Is the dog-head entry-level SLR really inferior to the micro-single in some cases? Tian Ji horse racing! See how you compare. Each has its own advantages! Some people like big ones, while others like convenient ones. What are you talking about?

The best micro SLR is much better than the most basic SLR. It's not just a little difference.

Of course, this is on the camera, not the fuselage! The fuselage is basically the same, but the control ability of each parameter is different. A good micro-camera has great advantages in image processing, high sensitivity and night shooting. I think that's what you mean!

If you just talk about the fuselage, it is better to use a SLR fuselage! Fast focusing and shooting are the biggest advantages of SLR. As far as imaging is concerned, it still depends on the lens. Nowadays, many cookies with fixed focus are of good quality.

What is a dog's head? Some dog heads are also good! For example, Canon's 17-55. Of course, some bull heads can't be inflated.

Can't say who is good and who is not.

I agree with you as far as the topic you mentioned is concerned. Sometimes it is not as good as micro-single!

But I personally prefer SLR, even if it is an entry-level machine, even if it is a dog's head.

Question 3: I don't understand the lens parameters of the micro-camera, and I hope to explain them in common language. Thanks for the example:

10 -22mm 1:3.5-4.5

10-22 is the focal length, with the front number small and the back number large. The smaller the number, the wider the viewing angle, the larger the number, and the farther the shooting.

3.5-4.5 is the aperture. The smaller the number in front, the more you can take pictures in dark places. The number in the back 4.5 position, beginners don't have to pay attention to him.

If the parameter is 50, 1: 1.8, the focal length is unchanged, only 50, and the aperture is unchanged, only 1.8.

All right, preliminary answer is complete.

Question 4: Why do you say that the guest has no dog head? Reason:

1. Pentax's production capacity has always been insufficient. Only one or two lenses can be produced in the same focal length. It is impossible for a focal segment like Nikon Canon to produce low-end, mid-end, high-end or even more lenses, so either a focal segment has only one head and the imaging work is well done (such as Princess Biscuit). Either similar focal lengths are slightly lower and higher (such as 16-45 f4 and 16-50 f2.8), then the slightly lower-end head will be much better than the lowest-end head produced by Nikon Canon, and even close to the level of other household heads.

2. The current Pentax head, whether it's a chicken at RMB 300 18-55 or the most expensive 300 cannon, will be coated with SMC (of course, the coating on different grades of lenses is different), so the low-end Pentax head will be better than other dog heads coated with * * *.

3. Generally, the Pentax lens works well, and the zoom damping and full-time manual operation are basically available. Even with the cheap 18-55 dog head, the focus of the front lens does not rotate (the filter is good), the hand feel is better, and the sharpness of the lens is not bad, which is much better than other dog heads 18-55.

The above three points, so the guest has no dog head. ...

Question 5: What is the difference between SLR and micro-single? /kloc-which one should I buy at 0/0? Hello!

Sony NEX series is recommended for micro camera, which is also the most beautiful and thinnest micro camera with interchangeable lens.

It is suggested to choose Sony NEX-5R, which is popular in the market at present.

Reference price: 3850-4 100 yuan (with 15-50mm lens sleeve)

5500 yuan (equipped with 16-50mm, 55-2 10mm double-head floating machine)

NEX-5R has perfected and added many humanized elements on the basis of the previous popular model NEX-5N.

The difference between NEX-5R and NEX-5N:

1, 180 degree flip screen (NEX-5N can only be adjusted upwards by about 80 degrees).

2. Add a turntable to improve mobility.

3.WiFi wireless transmission function

4. The new video scaling is smoother.

5. The new head is more portable

The sensor has also been upgraded to a new CMOS that supports phase difference focusing, adding more buttons for easy operation.

Question 6: What's the difference between a micro camera and a SLR camera? The biggest difference is that SLR can capture objects that move instantaneously, but micro-single can't. This is determined by nature. SLR is the light reflected by the ingot prism, and the microlens is electronic. Therefore, the instantaneous movement of micro-snapshots will definitely be delayed.

Question 7: Which is more suitable for beginners of photography, SLR or micro-single? Single-camera is designed for those who don't want to carry heavy machines and want to take good photos. Although it meets the needs of these people, technically, it still can't reach the performance of SLR. It is ok for ordinary people to use it at home. There are still shortcomings in taking excellent photos.

If you like photography as a hobby and want to practice photography skills well, it is recommended to get a SLR for fun if economic conditions permit. As far as the current imaging, electronics, digital and optical technologies are concerned, it is still not recommended to buy them in a hurry. Directly on the SLR! ! !

Question 8: Ask for a micro-order with a good photo, and the price is around 3000! There are many choices for micro-orders with 5 points, around 1, around 3000. At present (the price of the same camera varies greatly from manufacturer to manufacturer, and I take Ma Yun's middle price as the standard), the micro-orders on the market mainly include Canon EOSM3, EOSM 10, Sony A5000, Fuji XA2, Panasonic GF8, GX7, Oba EP5, EPL7, and so on.

2, different uses, the choice of results will be different. If you take pictures as a souvenir and don't plan to use or learn to use image software (such as Adobe Photoshop), the color and noise suppression processing ratio of the camera image processor will be relatively large, which means that the quality of direct output will be higher; On the other hand, the latitude and color depth of the sensor are more important, that is, there is more room for later;

3. From the perspective of hardware configuration, it is more important to pay attention to the sensor, lens and control when choosing a camera, in which the sensor and control are integrated with the fuselage, and the microlens can be replaced or added (which is related to whether to upgrade the lens in the later stage). The lens quality, lens type and quantity of each brand are different. I only introduce the quality of condoms.

4. The gold content of the camera mainly refers to the image quality (imaging quality) and the control (shooting success rate) (of course, whether the fuselage material is metal or plastic also needs attention, but it is not very important), of which the image quality accounts for 60% and the control accounts for 40%. Some cameras have good image quality, but they are not well controlled (such as out of focus), which is useless. In the percentage of image quality, sensor quality accounts for 45%, lens accounts for 50%, and image processor accounts for 5%;

5. sensors. The sensor is similar to the negative of a film camera, and its working principle is to convert photons (light elements) collected by the lens into electrical signals. A good sensor has fast photoelectric conversion speed, less noise and accurate restoration of color pixels (RGB three elements). In digital cameras, the larger the sensor area, the better the quality. Among the above cameras, Canon, Sony, Fuji and Samsung use half-frame sensors (the area is 23.5X 16.5mm, and Canon is a little smaller and can be ignored). Panasonic and Oba adopt 4/3 frame sensors (area17.3x13mm); Nikon uses a 1 inch sensor (area 13.2X8.8mm). Among the sensors with the same area, the color depth, dynamic range and available high sensitivity of the sensor are mainly considered (there are relevant evaluation data for reference, such as the evaluation data published by DXO Laboratory of France, the most famous third-party sensor evaluation institution in the world, which can be found on DxOMark website). Accordingly, the sensor quality of the above cameras can be ranked as EOS M3 >: NX 300 >: a5000 & gtXA2 & gt； EP5 & gtGX7 & gtEPL7 & gtGF8 & gt； eosm 10 & gt； J5, according to the color processing and noise processing in photoelectric conversion, EOSM3, XA2, EP5 and GF8；; Is better.

6. lens. The lens is complicated, professional and not easy to understand, and there are differences between the bull's head and the dog's head, such as resolution, luminous flux, distortion, dispersion and dark angle, so there is no bottom. I will simply sort by camera lens, Oba > Panasonic > Canon > Fuji > Nikon > Samsung > Sony. However, because the lens has a great influence on the image quality, many people are often dissatisfied with the lens set after using it for a period of time, so they will upgrade the lens or increase the lens to optimize a certain shooting theme, such as a large aperture lens for portrait shooting, while various brands of lenses only use their own bayonet (only Panasonic and Oba are more common), otherwise they will have to change doors and spend a lot of money, so they should have a general understanding of the lens. Among the micro-lenses, the 4/3 system (Panasonic Oba) has the most varieties, which is frugal and casual (the quality of low-end lenses is relatively good, and the high-end lenses are supported by Leica lenses). Sony Zeiss lenses, Sony G lenses and Samsung Snyder lenses (larger in size) are few in number but high in quality and expensive. The lens group of Fuji micro-lenses is not as rich as the 4/3 system, but more than Canon micro-lenses.

7. Image processor. The work of image processor >>

Question 9: Please come in and answer the two questions about buying red circle lenses and micro-orders patiently. Thank you very much! ! ! Indeed, as you said, the quality of the red circle zoom head is limited compared with the dog head, and few people can see it at a glance. The fixed focus head, especially the top fixed focus head, will have a clear gap with the dog. In this respect, if you look at more photos, the resolution of your eyes will gradually improve.

Convenience and image quality are inherently incompatible. If you buy a SLR, you should take the picture quality route, and don't dislike its large size. If you can't stand the bulky SLR, you can also choose a micro-single, that is, the micro-single has no full width, and the choice of lens is smaller than that of SLR. Your 60D+ 18-55 machine case is not higher than the micro-single in image quality, but it is better than the micro-single in control, grip and style.
