What is a mirrorless and what is a mirrorless device?

Mirrorless camera. A new type of word, micro-simple is given two meanings: micro, miniature and small; Picture quality of single-lens and DSLR cameras. In other words, the term refers to the small size of this camera and the image quality of a DSLR.

In June 2010, Sony launched its first "mirrorless" cameras, the NEX-5 and NEX-3. Mirrorless cameras are portable, professional and fashionable, and the target customers are mainly those who want to get very good picture expression on the one hand, and the lightness of a compact digital camera on the other.

In addition, the 18mm flange pitch and the same area size as the CMOS sensors used by the current mainstream SLRs make it ideal for adapting to a large number of manual lenses that have been handed down from the early years. Therefore, NEX mirrorless is also very marketable among photography enthusiasts!

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.

At present, the consumer electronics giants involved in the field of mirrorless cameras include Sony, Panasonic and Olympus, which are more representative.

Single-lens is the norm for single-lens electronic viewfinder cameras.

Micro is Sony's name for its nex3 and 5, and the A33 and A55 that came out later are also called single electricity.

Sony calls nex3 and nex5 mirrorless, which is a consideration for commercial naming, but their bodies do not have an electronic viewfinder and cannot be externally connected, so it is not appropriate to call them single-electric. Similarly, the Olympus E-P1

The difference between a single electric and a single reflex is only in the framing, the single reflex is reflected through the reflector to the pentaprism (pentanomial mirror), and then reflected to the viewfinder window.

There are two kinds of single electricity, generally the signal of the sensor is transmitted to the electronic viewfinder, while Sony's A33 and A55 are converted into digital signals after being reflected through the half-lens, and then given to the electronic viewfinder. (The lens upstairs is completely wrong whether it is powered or not, it is originally a translucent reflector, 70% of the light passes through the sensor for imaging, and 30% is reflected to the focus module and electronic viewfinder module).

Imaging quality: Except for Sony's A33 and A55, which use Sony lenses, the other single batteries are special bayonets, and the flange distance is much shorter than that of the SLR, so the edge imaging is relatively poor. But the gap is small and can be ignored.

However, A33 and A55 use fixed half-lenses, which loses 30% of the light, which is equivalent to a smaller aperture, and a higher sensitivity is required to achieve the same ** amount.

If you want to recommend, I'll go into more detail.

One meaning, mirrorless is a noun coined by Sony, other homes are called single electricity, the biggest difference between Sony is that there is no active reflective part, with a piece of lens that becomes transparent after power, and is reflective without electricity, which is the so-called fixed semi-lens technology.

The imaging quality is also between the SLR and the card, my understanding is that this is a simplified version of the SLR, so it will never have the ability to surpass the SLR in terms of image quality, it is the extreme, that is, the volume weight of the DC + the image quality of the SLR. It is the product of a single reverse weight and volume compromise, and no one dares to say whether it is a future trend.

As for whether you pay for it or not, I don't pay for it anyway.

It is not recommended that the landlord choose a mirrorless (or single-electric) camera, which is high in cost performance, although it is small and convenient, it consumes a lot of power and is very slow to focus. Mirrorless (or single-electric) cameras are framed, browsed and changed settings through the screen, and the screen consumes the most power, a dry battery does not take long, in addition, mirrorless (or single-electric) corresponding to the lens is very few, it is difficult to upgrade, it is better to buy a card player or SLR camera directly. Like C and N, the two largest camera manufacturers in China have not launched mirrorless (or single electric) products, you can see its market space Or choose a SLR or cost-effective card Bar Recommend the new card player of the IXUS series and Canon 60D SLR, both of which are not bad

Then you will go straight to SLR.
