How do ordinary digital cameras take long-range and close-range shots?

Hardware can't reach the prospect, and it is controlled by optical zoom ability.

Close shot depends on macro function.

The suggestions are as follows

Generally, zoom cameras have optical zoom, that is, by changing the lens group to enlarge the object. Generally, when a telephoto camera zooms in and out, it will be accompanied by the sound of the zoom motor, but without the sound, the picture on the LCD screen will become larger. This process is digital zoom. Zooming ability is mainly determined by optical zoom, and it is used for publicity when digital zoom is used, at the expense of pixel quality. Let's compare the main parameters of several brands you mentioned:

Manufacturer model price optical/digital zoom anti-shake function

Canon SX30 3299 35x/4x 24-840mm optical image stabilization

SX20 3000 20 times /4 times 28-560mm without anti-shake function (not found)

Fuji HS112488 30x/2x24-720mm electronic image stabilization.

Nikon p 100 2499 26x/4x 26-678mm optical image stabilization.

P500 3500 36/4120,000 22-8 10mm LCD screen can be rotated (longest focal length telephoto machine)

Panasonic FZ40 2600 24 times /4 25-600mm optical image stabilization

Lx3 2700 CCD11.7 inch is the first choice for SLR.

I bought this LX3 in June 5438+February last year, which is not bad.

Among them, SX30 and Panasonic's LCD screens can rotate, and the cmos size is 1/2.3 inches, both of which are above100000 pixels, with little difference.

Mainly depends on your requirements for the color of the film. Generally, it meets the requirements of high shutter speed for news photography, and it can be snapped without delay.

The probability of reaching a difficult moment is high. You should also pay attention to the boot time, and you should confirm these parameters in the article on the use of the camera.

The comparison of the above parameters should have met your needs!

Canon: Powershot G 12 3800 yuan (JD.COM mall price)

S95 3 100 Yuan

Panasonic: LX5 3500 yuan /LX3 2600 yuan

Nikon: p7000 3200 yuan

The above CCD is11.6 inch to11.7 inch, and the imaging effect is better than that of 1/2.3 in the market, and they are all manual.

The cost-effective LX3, which belongs to Panasonic, is known as the preferred backup machine for SLR. Although it is a little worse than LX5 in focal length, it is

The cost performance is relatively high. I bought this at the end of last year. Very good, the imaging effect is good. I can increase the price and increase the lens myself.

And other accessories are also very good (you can search online)

The G 12 has stronger zoom capability, and the s95 is compact and easy to carry.

P7000 is a competitive model of G 12, depending on personal preference. The above models will not fall behind in 2-3 years! Because you said

I want to travel, so I don't recommend some fixed focus machines, such as Ricoh GX200 2700, which is not bad.

If the battery is equipped with a backup power supply, it can be used.

Model price pixel optical zoom range cmos LCD macro iso

S 9100 24001265438+100,000 18 times /4 times 25mm-450mm 1/2.3 inches, 3 inches, 920,000 4cm 160 above 2/3.

Sx22018501210 5 times 24mm- 120mm 1/2.3 inches 2.7/230,000 3cm 100 or more.

P100 24501000 26/4 26-67812.33/460,000 1cm 160 480g or more.

All have optical zoom, Nikon is a telephoto machine, and Canon is a card machine, with different functions.

The macro parameters are not very good. The mode of the card machine is smaller than the LCD screen and not as clear as Nikon.

If the iso is low, the effect will be better in the case of poor light! In addition, the price of JD.COM Mall is higher than that of Canon.

Easy to carry, the advantage of telephoto machine is that it is convenient to take long shots, depending on your own needs!

In addition, I took a look at Nikon P 100, and the price was good (all in JD.COM shopping malls), with longer focal length and better macro.

Other parameters are similar, even a little heavier, depending on the key point you choose!

P500 is good. Now the longest zoom telephoto machine sx30 is 35 times that of Canon, and the price is still competitive.

But they are all higher than your 2500 standard, so choose Panasonic's P 100 or FZ40 or Fuji's HS 1 1.

In terms of brands, Canon Nikon, Fuji Olympus Casio/Sony Panasonic have rich experience.

The first five companies had their own lenses, and later they used other people's, including Samsung, but Panasonic used workers from Lycra, Germany.

Okay, here we go. Canon Sony should sell better in home cameras. Sony's industrial design and customs are fashionable, but many people buy them.

Fuji's telephoto machine is cost-effective, Olympus's three-proof card and single battery are not bad, Casio's appearance and continuous shooting function are characteristics, and Panasonic's lx series is also good. LX series is the first choice for SLR. Canon's G 12 Nikon P series is also a high-end product in portable cameras, second only to SLR cameras, and the price is between 3500 and 4000. Although close to the cheapest SLR, portability is irreplaceable. Sony's several models are not low in price, and the parameters are not very good. It is better to buy a cost-effective Canon. Let's take a look at the parameter comparison:

Manufacturer model JD.COM price optical/digital ranging optical anti-shake electronic anti-shake

Canon 2101949 5x/4x24-120mm.

130 1599 4/4 Yes, 28- 1 12.

1051349 4/4 28-112 with high cost performance is recommended.

Sony T99D1699 4/8 25-100 Yes.

Wx5c1998 5/10 24-120 Yes.

W570 1579 5/ 1025 is,

Panasonic FH 1 899 5/4 28- 140 has.

Zs7215012-16/4 is.

Nikon S 60001499 7/28-196 has.

L110159915/4 28-420 double anti-shake

The pixels are all over12 million pixels, and the ccd size is 1/2.3 inches. So just look at the cost performance, whether it is telephoto or appearance, there are no other special parameters (on the model you choose). The telephoto ones are nikonL 1 10 and Panasonic ZS7, which have good comprehensive performance.

Nikon S6000.

There are two aspects to choosing a camera. 1 is what you use in it. Is it for general home use or professional study? How much is 2!

These two conditions are clear, just choose. Let's talk about the parameters briefly. Generally, cameras have pixel/optical zoom/digital zoom/photosensitive area (divided into CCD and CMOS imaging)/macro /LCD screen size and pixel, and whether it is a touch screen/whether it has optical image stabilization or electronic image stabilization. There are also some accessory parameters, such as whether the battery is a lithium battery or an AA5 rechargeable battery, the weight of the fuselage and so on. , mainly depends on the main parameters in front.

1. Generally, the number of pixels is between100000 and140000, which can generally meet the needs.

2. The actual zoom ability of optical zoom can make the distant scenery clearer, and digital zoom is post-processing which will affect the image quality.

Generally, regardless of CCD or CMOS, cameras can meet the needs, mainly depending on size. If the photosensitive area of11.6 inch is greater than 1/2.3 inch, the effect will be better.

4. Macros are the effects that affect the closed object.

5. The bigger the LCD screen, the more power it consumes, and the viewfinder can save electricity.

6. Optical anti-shake is realized through the supplement and control of physical displacement, and electronic anti-shake is post-processing, so it is best not to consider it.

7. Other batteries depend on personal preferences, whether to choose a telephoto machine or a general card machine, or a SLR camera and a single battery.

Based on the above conditions and considering the cost performance properly, you can choose a good camera.

The latter two models have optical anti-shake and metal body.

Sony models are as follows:

W5 10 1049 4 times 26-1051012.3 480 2.7/23f2.8-5.9

All have panoramic scanning, only 350 supports high-definition video, and the maximum aperture is the ability of F2.7 night scene. Only 350 has optical image stabilization, and almost all others are electronic image stabilization; I think 350 is a better parameter, depending on your personal choice.
