Brother Big Bus, I'm going to buy NEX-3 Hong Kong goods tomorrow, I'm afraid it's a refurbished machine. What do you think of shutter time?

Is this for me? I haven't seen it for a long time, but it's too late. It's a pity ... Generally speaking, you can see the number of photos, that is, the default number of photos is generally compiled from small to large, and the number is several times that of the shutter, but it seems that this number can be cleared. If you are not at ease, you can look for software to see if there is a special shutter number and try the light and shadow magician. I didn't pay much attention to this either, because the shutter can be changed. I always think it's enough to replace it when it's worn out, so I don't care too much ... you can ask the merchant for an invoice. If it is licensed in Hong Kong, you can definitely invoice, but ordinary second-hand or refurbished businesses are reluctant to invoice ... The answer on the first floor is a bit confusing. How many people play SLR without spare batteries and spare memory cards? It's only 200 yuan each, just fill it up in advance. People who really enjoy SLR basically don't turn off their phones when they go to the scenic spots, and they have to leave their cameras on when they don't take pictures, so that they can take pictures at any time ... Who told you that SLR is focused manually? Only Nikon's old D-head with machine without focusing motor will focus manually. All AFS lenses can be autofocused. For beginners, autofocus is very helpful, fast and accurate. When manually focusing on the captured things, the bayonet of the micro-single is the same as that of the SLR, and all the lens micro-single that can be used by the SLR can be used. Don't be so disdainful of new technology if you haven't used the micro-sheet on the first floor ... I said the micro-sheet is a SLR without a mirror, which was taken directly with electronic components. There is basically no difference in function except that there is no viewfinder and the fuselage is smaller than the SLR. The appearance is undoubtedly more pleasing to women, and novices don't need to overemphasize performance. If you are a technical school, as long as you have a camera with manual function, it makes little difference to you. If you don't want to delve into technology, and anyone who has played with SLR knows that the lens and tripod have a much greater impact on the imaging quality than the fuselage, there is no need to worry too much about whether the fuselage is SLR or micro-single ... The metering mode is a mode in which the metering algorithm in the camera takes the current light intensity. What is the problem based on? The automatic metering in the camera will calculate the exposure according to the measured light intensity, and give the exposure time or aperture size according to the exposure, and where was the light intensity taken? For example, when the metering mode is spot metering, the light intensity at the focus will be used as the benchmark parameter (it is not recommended for beginners to use spot metering, which is often prone to errors), and if it is central area metering, the camera will take the light intensity of an important area of a viewing angle as the benchmark parameter, and so on, as well as matrix metering and center weighted average metering. , can be explained in the manual, generally use the central weighting or matrix (different brands of cameras have different names), because they are generally used.
