40D SLR, 2500, is it worth it?

2. Judging from the number of shutters, the so-called maintenance should be to replace shutter components.

3. The parts that are easy to break inside the SLR are the shutter and the shutter button. Other parts are not easy to break. So personally, I think there is no problem. Can be purchased.

I just bought a second-hand 30d myself, and it has been used for half a year. The current situation is good. Replaced the shutter button. The shutter life of the mid-range machine can reach 654.38+ ten thousand times. If you are not a professional photographer, the number of shutter times a year should not exceed 1-2w. So it won't be a big problem. 2500 is a good price. I bought it for 30 days, 2300 yuan. So I suggest you start with the machine in good condition.

5. Find out whether the photosensitive element ccd has been wiped. Whether there is any damage after rubbing. If there is any damage, it depends on the impact on imaging. This is more important. My machine was dusty when I bought it, and then I wiped it myself, and I accidentally rubbed it. However, the current situation does not affect imaging.
