Entering the pit of Dafa, we started the A7R2, and the silver of the year was gone. We entered 55 1.8 again. From the start of the familiar operation, we started photography in full scale. If we find that we cannot hold the grip, compare the previous Pentax SLR. Niche, I hope that Dafa can and PK about CN), especially people do not trust, then want to start a set of sets. Aunt Zhang’s home search found that this is too small, in addition to see a Nikon's silicone sleeve, nothing else. I bought a set that I thought I could, and sent it for your reference. It was my debut at the Aunt's place. (When the New Year's candidate display bracket was written 80%, it was too lazy. Now the table is changed.) Aunt Zhang did not, but had to search the Internet, there is the original, tall, the price is also tall, there are silicone, there are cortex prices ranging from tens to hundreds, choose a relatively large number of sales The Tmall brand shop, mainly his video will be more clear, use it, I feel it is more reliable. There are two styles in his house, one is a battery cover, but there is a copper buckle in the grip, one is without a battery cover, there are three colors, the price is the same, the video introduces brown leather hard, black leather Soft, from the picture, brown retro texture and some, black is relatively low-key, not significant. After thinking about it, a photo enthusiast is still not very good. Beijing is gray, I fear that if I don't have the lid dirty, I have to remove it to clean it. So I bought it with a lid. I have a big hand and the brass buckle has no effect. When choosing a suit, his family had free shipping for two pieces, thinking that he needed a wristband, and that his wristband was well designed and placed orders together. “Very Release Brand Preface: This Sony A72/A7R2 leather case has been finally marketed by our team's meticulous research and development. The leather case production process is completed by hand. The bottom of this leather case uses the airborne aluminum-magnesium alloy material as the skeleton. Better protect the camera and keep the holster free from distortion." Also seeing the other expensive sellers have such a description. They don't know who is the first one. There are domestic brands, Taiwanese brands, and Italian brands. This will not be commented on. Which brands are these countries? Leave no comment. After photographed, three days of arrival, out of the box After unpacking, a set of a copper screw, a velvet bag (not known at the time of the purchase), a wristband Holster details Velour bag Rear view effect Front effect Upper viewing fit Bottom effect The overall effect of the wristband after installation Open and close effects of various interfaces after installation Handheld effect After using it for almost two weeks, I thought it was okay. At least I did not feel that there was a lack of use. advantage: 1, very fit A7R2 body, good texture, soft leather, feel comfortable. 2, the bottom of the aluminum-magnesium alloy skeleton is relatively strong, casually do not feel bad. 3, After adding the sleeves, the grip feeling is much better, and the little finger is released. 4, the design is more reasonable, replace the battery, card, use a variety of interfaces do not have to remove the leather base. 5, the business website does a good job, video introduction is more clear. 6, wristband more creative, safe and convenient to use Disadvantages: 1, the price is still a little expensive, buy a single package, if you can have a discount is better. 2, the lower part of the screw is recommended to replace the stainless steel, copper is a bit soft, the shelf gives people the confidence is not strong, more micro-single and SLR weight almost. Electronic Components Transformer
Transformer is a device that USES the principle of electromagnetic induction to change the ac voltage. Its main components are primary coil, secondary coil and iron core.The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.According to use can be divided into: power transformer and special transformer (electric furnace change, rectifier, power frequency transformer, voltage regulator, mining, audio transformers, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.).The circuit symbol T is often used as the beginning of the number. Examples: T01, T201, etc.
