If you want to buy a professional digital camera, please recommend!! Additionally How about the Cano

G12 belongs to the so-called consumer flagship products, that is, a small area of the image sensor with close to professional control function, at first glance the effect is stronger than the card, but after all, this kind of product is similar to the card of the small image sensor composed of (to put it simply, the full SLR is as large as the original 135 film, APS SLR area is about half smaller, M4 3 is one-fourth of the full, and consumer flagship, half is smaller and weaker).

To put it directly, the area that receives light is much smaller, so the outstanding problem is that in low light and night scenes, the performance is not good, the picture is grainy, or the shutter is not up, and it is easy to blur in layman's terms.

In addition, from the first point of view, the G series really does not have an advantage. More expensive than some entry-level SLRs.

My suggestion is that if you want to think about performance and lightness, you might as well consider the so-called mirrorless cameras that are popular now, such as the Samsung NX series, the Sonynex series, or the Panasonic GF series. The entry-level ** is only about 3k.

Or don't care about the weight, you can also consider the SLR, it is recommended that the SLR start from the mid-range body, the performance of the entry product is very limited, and it is not enough to fill your needs for further learning and development.

The G12 is good, with a 1-inch bottom, and even better is the G1X; Or Sony's RX1, the digital camera with the best image quality, is expensive, without zoom, Sony and RX100 are very good.

Professional digital cameras are recommended to buy micro-mirrors and the like, the operation is basically the same as the SLR, there is a full manual transmission, the image quality is between the card SLR, you can also start with the SLR, but you have to consider the cost, no rice is not recommended, lens accessories and the like are very expensive, G12 is good, but the cost performance is average, it is better to buy a micro-single, depending on your preferences and requirements.

How many majors do you specialize? The G12 model is a bit old, it belongs to the micro mirror, and the professional has to be the SLR D3200 entry-level set of less than 4000** can be considered.

It is not recommended that you buy G12, super I don't recommend you to buy it, the reasons are endless at once, you can buy SLR directly! Kiss!

You might as well buy a Sigma 24 70 ...

**Almost... The performance is much worse!

If you don't want to change the phone, Canon can directly choose a full-width 5D2 or 5D3 entry point for 550D, 600D, and 650D.

If you want to use n products, you can use the same stage of the product.

It is recommended to buy a single reversal directly.

Canon is good, or Sony's.

1. Please introduce the sensor size, what is the combination between the number of optical zooms and the focal length to maximize the benefits?

This is not very clear. To put it simply, the sensor size represents the grade of the camera to a certain extent, the bigger the better, it is meaningless to blindly increase the pixels without increasing the sensor size, and the sensor size has nothing to do with optical zoom and focal length.

The distal value of the focal length divided by the proximal value is the optical zoom factor. For example, if the zoom range is 24-72, the optical zoom factor is: 72 24=3x.

2. The 1 of the S95 is much greater than the other 1, so the image quality advantage is not small. The S95 can basically be regarded as a backup machine for professionals, while the SX210 is just a fashion card, not a machine of the same grade. Due to the large size of the sensor, the S95 is much better in low-light environments (even compared to all other brands of laptops, the S95 is one of the best in low-light imaging!).

The 14x optical zoom can shoot quite far away, which is much farther than the S95, which is more convenient. However, if the lighting conditions are slightly bad, the success rate of telephoto end shooting will be very low (hand shake), and even with image stabilization, the effect is limited, so the practicality is not very strong.

Therefore, if the landlord wants to shoot a good **, choose S95, which is definitely a good machine;

If you want to play casually, don't care about the image quality, and don't want to play photography well, then SX210.

Generally speaking, the bigger the CCD, the better. 1/ > 1/

The S95 is stronger than the Sx210

A large optical zoom is not too useful, so don't be superstitious about it. The optical zoom of the card machine is basically the limit at 4x, and the image quality is greatly reduced.

First, the larger the zoom range, the worse the imaging effect, which is limited by the physical structure and cost of the lens. Especially on the small body of the card machine. When you look at the big zoom cannon heads that shoot sports on TV, they are all huge ones.

The second is that the jitter will be very strong at the telephoto end (large zoom factor), and it is difficult to shoot well without a 3-corner frame or placed on a stable platform**.

The S95 images better! Optical zoom isn't really very useful, and the S95 has better image quality and is better in darker environments. The 14x optical zoom doesn't have much practical use.

The first one is the most cost-effective, especially for people who don't understand photography at all, its focal length is practical, the wide angle is large, the scenery is particularly good, the telephoto end is also enough, the image quality is definitely not as good as S95 but it is similar to SX210, but it is reasonable, and the shape is ultra-thin and fashionable or a metal shell.

You can buy Panasonic FP1 or FH1, and the licensed plus memory card and spare battery are about 900 yuan, which is the most recommended. Panasonic is the No. 1 in the consumer DC field in Japan, and is known for its high quality and high price.

1. Fuselage. Recommend Pentax K52S, (alias two silly). First, Pentax's sensor is developed by Sony, and the research and development strength of Sony's sensor is very strong, especially the dynamic range and color depth are good, Leica, Nikon, and Olympus all use Sony's sensors; Second, Pentax's control is very good, especially the focusing accuracy is first-class; The third is that Pentax's fuselage is small and the craftsmanship is very good, the metal fuselage has a shoulder screen, which is dustproof and drip-proof.

Compared with the horizontal Canon, Nikon, and Sony fuselages, the advantages of Pentax K52S's fuselage are more prominent.

2. Lens. Pentax's number of lenses is not as good as Canon, Nikon's, and not as good as Olympus and Panasonic, but if you don't burn the lenses, no matter how large the lens group support is, it has nothing to do with you. And the photographer's mantra said:

The Pentax lens is not a dog, and the bull is not a cow, which shows that Pentax's pullover quality is very good. Therefore, it is recommended to use Pentax's 18-135 sleeve focal length, but the aperture is not large enough. If you like to shoot sugar water portraits with a bokeh, you can re-enter the fixed-focus large-aperture lens, which is not a problem.

3. Chip (i.e., image engine). Pentax chips are very good, especially the straight out is very beautiful, and the film can be produced without post-production, (the post-production is more beautiful), and the Pentax Green Oba Blue in the photography circle is very famous.

Therefore, I recommend Pentax K52S, plus spare batteries, UV mirrors, camera bags, high-speed large-capacity SD cards, it is definitely less than 10,000 yuan.

For the landlord's reference.

What type of things do you want to shoot, so it is good to recommend, Nikon generally shoots flowers and plants, Canon mainly shoots portraits.

To get started, we recommend the Nikon D90

Personal advice and opinions for your reference:

The Canon ixus100is is a card player with a telescopic lens, which has slightly better imaging results than a card player with a periscope lens.

The Canon ixus100is is a fully automatic camera, for a variety of complex and changeable shooting environments, can not be manually adjusted aperture, shutter and other parameters to obtain accurate **, but can cope with a variety of complex and changeable shooting environments through various pre-set shooting modes in the camera, but in poor light conditions, especially when shooting night scenes, the imaging effect will not be ideal, but the general home is fully competent.

Canon's new models include Canon IXUS100IS, and Canon IXUS IS old models, the most important imaging device photoreceptor chip CCD size is almost the same, all about 1 inch, although some have about a million pixel number of improvements, there is no major substantive difference in the actual imaging effect, basically the same type, the same grade model, are fully automatic cameras, belong to new bottles of old wine, without any outstanding functions, only some more fancy functions that have no impact on improving the imaging effect, because it has just been launched, ** is high, and the current cost performance is low.

Canon ixus100is** at around 2000 yuan, Jiangsu area.

Canon IXUS100IS at this price, you might as well pay attention to the Canon IXUS980IS, better performance, worthy of being the flagship model in the Canon IXUS series, the main advantage is that the CCD size of the sensor chip is relatively large, about 1 inch, the large size of the sensor chip with more than 10 million high resolutions, can really bring higher quality imaging effects, in addition to a variety of shooting modes pre-typed in the camera, it has a comprehensive manual shooting function, Especially when shooting pure night photos, after manually adjusting the shutter, aperture, ISO and other parameters, the resulting photo effect is clear and clean without any noise, which is incomparable to the imaging effect shot by the Canon IXUS100is with a so-called program mode (commonly known as point-and-shoot mode) camera such as night mode.

Canon A590IS, A650IS, A720IS, ** around 1300-2000 yuan, the performance is also better, the main advantage is the same as Canon IXUS980IS, with a comprehensive manual shooting function.

Among them, Canon A650is is better, the main advantage is that the CCD size of the sensor chip is relatively large, 1 inch, and the large size of the sensor chip with a high number of about 1200 million or more can really bring higher quality imaging results.

Buying a camera is the same as buying a computer, what suits you is the best, you can compare them according to your own price and preferences, and check the information on the Internet.

It is too expensive, and the range of light variation is small.

The selection of the camera should be based on the size of the image sensor, lens style, quality, optical zoom range, aperture, ISO, image sensor pixels, etc., try to choose a large CCD, periscope lens imaging poor.

The true size of the 1-inch CCD is. Entry-level SLR sensor size mm, full-width SLR sensor size.

The high pixel of mm does not mean that the image is good, and the pixel is only increased without increasing the sensor size, and the sensor is overloaded and loses accuracy, and it is easy to appear small spots or strange colors when the light is poor.

Fashion choice Sony, photography choice Nikon, Canon, Sony video camera is very good, the camera is average, low cost performance.

The card machine is more than 1700 on the luxury, less than 5 times the light change on the low-end AA convenient, cheap, with 2 and 2 other 2 spare, 4 charging AA is only more than 100, in case there is no power just 2 AA on the line, lithium is expensive, in case there is no power and no play, it is recommended that Speedmaster and Nanfu high-capacity rechargeable batteries.
