Last year, a second-hand sony heka 3 was purchased from local friends at 2,500 yuan. The article is as follows:
After using it for a period of time, she felt the benefits of Sony Dafa. Her husband liked to travel, so he bought the SONY A7M2 full-frame micro-single and FE 28mm F2 lens.
Body: SONY A7M2 full-frame micro-single
Lens: FE 28mm F2
In order to package the quality of the product, we chose to purchase from Sony's official website.
And if you purchase from Sony's official website for a long time, you can accumulate growth value and upgrade from ordinary member to gold member.
Her husband's "unremitting efforts" has now been upgraded to a gold medal member! And can enjoy the gold medal membership price, in some cases than Jingdong price is also appropriate, and can guarantee product quality! So under normal circumstances, we have chosen the official website for buying Sony products.
The above is the treatment enjoyed by different members
Second, the camera's choice - Sony A7M2Digital cameras are classified into applications: SLR cameras, micro-cameras, card cameras, telephoto cameras, and home cameras.
The photo effect of a card camera can no longer meet the needs of my husband. There is still a Sony TX66 at home to eat ash at home, and even salted fish are almost too fast to sell...
SLR cameras are mainly heavy weights, they feel a little burdensome on the road, and they want to buy a good SLR price is too high.
Ever since, we have chosen a comparative compromise - the micro-single camera, which has a slightly smaller size, but also the general SLR image quality.
After classifying from another latitude, the camera classifies half-width and full-width machines.
Full-frame is that the size of the frame is the size of the traditional 35mm film film era.
A half frame is a frame that is smaller than the full frame, about half the size, so called half frame (APS-C).
The difference between the two is the difference in the size of the photosensitive elements, the photosensitive elements are large, resulting in a high cost of the camera, so the full-frame camera is more expensive.
Now most professional lenses are designed with full-frame as the standard. The full-width head can be attached to the half frame, but the effect is definitely not as good as full-frame. In addition, the lens with a large light-sensing element will have a high sense of performance, so it is better to take a picture when the camera is taking photos or the lighting is dark in the night. Blurring effect, full frame will be better than half frame.
All in all, a penny, a precious, expensive reason.
So the last bite of a grunt, came to a 9599 yuan Sony A7M2!
Third, the choice of lens: FE 28mm F2There are two main aspects of buying a camera:
1. What are the main shots of the shot?
Generally divided into: landscape photography, portrait photography, humanistic photography, news photography, sports photography. As a newcomer, most people should have the same needs as me: when traveling normally, pat the scenery and pat the family.
How much is the budget?
Since it was still in the beginner stage, the body had already selected nearly 10,000 devices, and the lens still learned from scratch. The first A7M2 lens we chose had a budget of less than 3,000 yuan.
Above all, we have chosen the SONY A7M2 full-frame micro-slim body +FE 28mm F2 lens.
Fourth, lens + body appearance Introduction 1, lens FE 28mm F2 parameters
Sony's FE 28mm F2 lens is smaller and the 200g weight is also portable.
Under the focus ring is printed with a more compact lens model: FE 2/28 ~ simple and generous.
Focus ring for the metal material, feels good, but it is easy to attract dust, the picture, you can see the outside of the fuselage has been part of the gray ...
Because of the small diameter of the lens, the filter lens aperture is only 49 millimeters, and the closest focusing distance is 0.29 meters.
The reason for the lens filter aperture is 49mm, mainly for the installation of other filters to use: such as fisheye lens, ultra-wide-angle lens.
SEL075UWC Super Wide Converter
SEL057FEC Fisheye Converter
The lenses in front of the lenses were coated with blue and light green colors and equipped with 9 circular aperture blades.
The mount of the lens is made of metal, made in Thailand Made in Thailand, and has a drip-proof splash.
The standard hood is petal-shaped, plastic material.
The inner surface of the hood is made of matte material as a matte finish.
Five, Sony FE 28mm F2 lens with Sony A7M2 body effect
Compact lens with Sony A7M2 can also be considered very coordinated!
Bring a hood, feeling a bit top-heavy ~
Six, Sony A7M2 full-frame micro-single appearanceBecause the airframe has been used for some time, please ignore the various gray above...
This model has no flash, and you need a friend to buy it separately! Sony's official website starts at RMB 1,000~
On the left side of the camera is the microphone and MENU button, and it is marked with SteadyShot INSIDE, which specifically emphasizes optical image stabilization!
The right side of the fuselage is: Mode dial, exposure compensation dial, A dial, C1, C2, open key.
The keys behind the fuselage: delete keys, playback keys, middle keys, custom keys.
Overall speaking, the A7M2's body feels good and the buttons are comfortable!
About the camera's internal system, settings, not much to say here, many valued friends have already introduced sony's system using the ~ A7M2 system also follows Sony's usual system.

It is also possible to shoot several pictures in succession vertically, and synthesize them using Adobe Lightroom, as shown in the above picture, so that the effect is better than the panorama and the scenery is more comprehensive.
Eight, summary of the lens summary:Lens appearance is relatively fine ~
The lens performs well under large apertures!
The lens has a strong overall resolution performance;
Lens support to add a variety of filters: fisheye lens, ultra-wide-angle lens and so on.
Distortion is more noticeable in some photographs and later software adjustments are required.
Body summary:The whole body is very hand-feeling! The weight is still acceptable, at least lighter than SLR, haha!
A variety of shortcut keys are set to facilitate different users' habits.
Focusing speed, accurate and accurate!
Anti-shake function to reduce the number of pastes. With the help of anti-shake, ISO can be lowered a little, which makes the purity of the screen also improved.
To sum up, at present, the Sony A7M2 full-frame micro-single is a machine that I currently prefer, the Sony FE 28mm F2 lens is a high-cost one in the full-frame lens!We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for 11kV cast resin Dry Type Transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.
