Digital camera (high score reward)

The landlord's questions are all the focus. Let me answer your question. If there are any mistakes, please ask other netizens for advice.

Question 1. Which is better, a telescope lens or a periscope lens?

In principle, the two are the same, and both zoom by moving the lens. Periscope lens is based on the principle of periscope on submarine, which was first seen in Sony T series cameras, and now almost all brands have this kind of camera.

Telescope head: advantages 1. Reduce light loss.

2. The aperture is larger than the periscope lens.

It's easier to make a wide-angle lens.

Disadvantages: 1 The lens is exposed outside the fuselage and is easy to be bumped.

Periscope lens: advantages 1. Beautiful appearance.

2. The lens is not easy to bump.

Disadvantage 1. The incident light will be refracted, and it will definitely lose light.

2. The pore size is usually very small.

3. Slow zoom

4. Because the fuselage is generally thin, the battery is also thin and the working time is short.

Personally, I think it's best to buy a telescopic lens. Pay more attention to the lens when using it. After all, the quality of photos comes first.

Question 2. There seem to be many kinds of memory cards. What kind of cards are more popular? Reading fast?

At present, except Sony, consumer digital cameras still use memory chips, and other manufacturers basically use SD cards. At present, SD cards above 4G are all high-speed cards based on SDHC standard. At present, the largest SD card is 32G, and it is possible to produce 1T or 2T SD cards in the future, so it can be said that the prospects are bright.

Question 3. What is the popular CCD size now? How about 1/2.3?

The popular model is 1/2.3, but it is suggested to choose a camera with fewer pixels based on this area, such as100000, which can reduce noise. This question is very important. The more pixels, the better, but the right amount.

Question 4. Is the equivalent focal length bigger, the better? Or whether the initial focal length is all 35mm, and then multiply it by the zoom factor to get the effective focal length.

The larger the focal length, the more practical the camera is (it can take a close shot or a long shot), but it also increases the size of the camera and reduces its portability. Therefore, according to the preference of the landlord, if you want to shoot a distant local scene, you can consider the telephoto machine, and vice versa.

The initial focal length is not all 35mm. If it is a wide-angle lens, there will be 24mm, 25mm, 26mm, 27mm, 28mm, 29mm and 30 mm. So many focal lengths are actually the result of manufacturer differentiation. Personally, if you want to consider the wide-angle lens model, 28 mm is enough, which is more serious than the wide-angle distortion of 28 mm. Of course, there are exceptions, such as Leica LUX4.

But the price is too high, enough to buy a mid-range SLR. The effective focal length is multiplied as you said, yes.

Question 5. What is the minimum battery capacity? Suppose you took 200 photos.

Generally speaking, battery life is related to three aspects.

1. Battery capacity

2. The power consumption of the camera

3. User's usage, such as: the number of times of switching on and off, the number of times of playing, etc.

As far as battery capacity is concerned, if you shoot 200 sheets according to TIPA standard, it will almost reach 700 mAh.

I can recommend several models for your own consideration. Pocket machine: Sony WX 1, W290 Panasonic LX3 (water machine, but expensive) ZS3 (pocket telephoto) FX 180, Pentax P70s12 (11.72 CCD).

I am engaged in the sales of cameras and camcorders. If you want to buy a camera in Dalian, you can go to Qingniwa, Dalian.

Take a look at Yum! Digital City on the first floor of Qiaohongfu Building. There are all kinds of digital products, operating 13 years.

Hehe, finally make a small advertisement for yourself, and just look for Kobayashi when you come.

I wonder if the landlord is satisfied with my answer. If you have any other questions, please post them again-
