Can you talk about how you recognize the emergence of mirrorless?

Mirrorless camera is a popular type of camera in recent years, compared with the traditional single-lens reflex camera, the main advantage of the mirrorless camera is that the mirrorless camera has a smaller size, so the mirrorless camera is very easy to carry, especially when traveling long distances, it can be lightweight, although the volume of the camera has become smaller, but because the mirrorless camera uses the same sensor as the single-lens reflex camera, the image quality is also particularly excellent, and the lens adapter ring can be used to use various lenses, which is more expansive than the single-lens reflex camera. So if the landlord is not a particularly professional photography enthusiast, I think the mirrorless camera can already replace the SLR camera.

When framing, the camera's CMOS, image processor, and screen need to work all the time. Among them, the power of the EVF electronic viewfinder alone is close to 3W, and the overall viewfinder power should be conservatively estimated to be around 4 5W. In other words, even if it is the third generation of Sony's latest A9 and A7 series, the battery they configure is only framing, not shooting, and it will run out of power for about 4 hours.

The entry-level mirrorless battery is even worse, and it runs out of power after about 2 hours of continuous framing. Therefore, there is no solution to the problem of mirrorless camera power consumption. Especially for travel shooting, activating the camera framing is equivalent to every **, CMOS, screen, and image processor need to work for 20 to 30 seconds.

And the DSLR camera only consumes power in a few tenths of a second.

There is an advantage that the mirrorless directly uses CMOS focusing, what you see is what you get, the LCD can see clearly, and the image is the LCD display, so there is no problem of zooming, and even the zoom horse lens is pointed to where to hit on the Sony mirrorless, and at the same time, the mirrorless can save us from the trouble of metering, and what we see is what we shoot. And from Sony's latest A9 A7R3 A7M3, compared with the second generation, the improvement is huge, the focus of the full screen, and the blessing of various black technologies, such as eye control focus, can greatly improve our work efficiency, which is why many wedding photographers are becoming more and more good.

In terms of structure, mirrorless eliminates the reflector, prism and optical viewfinder on the SLR, which greatly reduces the distance from the lens mount to the image sensor, so it can obtain a smaller body volume than the SLR, which is the biggest difference between the SLR and the mirrorless. In addition, SLR viewfinders are mainly based on optical viewfinders, while mirrorless mirrors are more direct use of LCD screens and electronic viewfinders. When I'm away from home, I still like mirrorless, it's more convenient to hold anyway.

In the long run, it is better to start with playing photography or buying a SLR, of course, micro-mirrors are Sony's world, no one can reach it, especially the top full-frame Sony A7R on the 17 market, all the functions are too perfect to kill all kinds of low-end SLR cameras, but Sony lenses are too expensive, and the lenses of each focal length are configured, but it is a lot of overhead. A good mirrorless is not micro, the SLR is not heavy, the micro mirrorless play is not as good as a good mobile phone, and the final suggestion is that it is the best policy to start with a low-end Canon or Nikon SLR camera, which saves a lot of money compared to A7R, just for reference! I don't buy a mirror, I'm more inclined to use a single-lens reflex with photographic technology.

Mirrorless cameras have a small size and a DSLR-like image quality, and its emergence meets the needs of most people.

Mirrorless cameras are just like smartphones, because the framing needs to activate the CMOS, image processor, and screen, so the standby response speed of the mirrorless camera is relatively slow. Let's use an analogy, if you suddenly see a scene on the street, the DSLR is raised to shoot, and the mirrorless camera is lifted up, and you have to wait 1 to 3 seconds for the camera to "wake up" from "sleep". This greatly affects the photographer's capture efficiency!

The CMOS of the SLR camera only needs to complete the task of ** imaging, and the focus has an independent focusing module. The focus of mirrorless cameras also needs to be undertaken by CMOS. At present, except for stacked CMOS, the refresh speed of ordinary CMOS is relatively slow, so except for Sony's A9, other models of mirrorless cameras are very poor in capturing sports scenes.

Mirrorless and SLR have their own advantages and disadvantages, and you can like that one. Old photographers may prefer SLRs, and I'm used to listening to the sound of the reflector lifting, and that's how I did. New photographers may prefer mirrorless and don't have so many old lenses to drag them down.

As for saying that mirrorless is lighter, this is not the most important reason.

There is still a distance from the SLR in terms of snapping, lens group, and battery life.

Micro mirror, literally you can understand two meanings. Micro: miniature and compact; Single:

DSLR corresponding image quality. In other words, this camera has a small size and a DSLR-like image quality. It is a crossover product between a digital SLR camera and a card player, and the main feature of its structure is that there are no mirrors and prisms.

The mirrorless camera uses a sensor with the same specifications as the SLR camera, and the optical viewfinder component on the SLR camera is eliminated, and the prism and mirror structure are eliminated, which greatly reduces the distance between the lens mount and the image sensor. As a result, a smaller body can be obtained than a DSLR, and the imaging quality is also guaranteed to be the same as that of a DSLR.

Mirrorless refers to a miniature single-camera camera.

The full name of the mirrorless camera is called the micro single electric camera, which combines some advantages of the card machine and the SLR camera, such as it has the advantages of high photo quality and clear picture quality of the SLR camera, and the advantages of simple operation and easy to carry the card machine.

It is neither a SLR nor a card machine, it can replace a single lens, but it is smaller and lighter than the SLR pants, and it is more flexible than the card machine, and the effect of taking pictures is better, so it can be said that it combines many advantages of the SLR and the card machine and appears as a camera product. Mirrorless is just a trademark of Sony, but in fact, major camera brands have different models of mirrorless products.

Mirrorless has also made a lot of difficult changes in focus, it does not have a reflector in the SLR, there is no prism, the distance between the lens mount and the image sensor is not so large, the body has become much lighter, and the image quality has not been reduced too much, usually using contrast-type focusing, the performance is slightly worse than the SLR, and the speed is also slightly slower.

Mirrorless cameras are not DSLR cameras. The mirrorless can be regarded as a weakened version of the SLR, it is still a certain distance from the real SLR, and there are many differences between the two, such as structure, function, **, lens, appearance, etc. Mirrorless mirrors do not have mirrors and prisms, while SLRs do; The lens of mirrorless lenses cannot be used with SLRs, and the appearance is smaller and lighter than SLRs; Cheaper than DSLR.

GF3 GF5 does have three sleeves, which are G14-42, which is an ordinary manual zoom, which is relatively large in size and with image stabilization.

14mm, is a biscuit fixed focus, very small in size, very light, can not zoom, and there is no optical image stabilization and X14-42, is an electric biscuit zoom, the volume is much smaller than G14-42, you can only use the lever to zoom and focus, there is also anti-shake.

If you have high volume requirements, GF5+X1442 is a very good choice, and other models recommend NEX5N, NEX5R+18-85 sets, Olympus EPL3+1442 sets.
