7.Panasonic TZ3, optical zoom: 10x, 3000 yuan.

8.Panasonic TZ2, optical zoom: 10x, 2650 yuan.

9.Ricoh R6, optical zoom: times, 2420 yuan.

10.Fujifilm S5700 (S700), optical zoom: 10x, 1900 yuan.

In no particular order.

The problem of pixels is not compared, and everything is not much different.

A710, S10, TZ3, TZ2, R6 belong to the relatively small telephoto camera, if you want to enjoy the fun of telephoto and don't want to bring too big a camera, these are good choices, among which the S10 shape is the most special, the pursuit of alternative can choose it. Although they both zoom at around 10x, the R6 and TZ3 TZ2 have a wider angle, and the latter two also have a wider zoom range. The advantage of wide angles is that they capture wider images when space is limited, so the latter two can be preferred, and they also have optical image stabilization.

The rest belong to the larger telephoto cameras, although they are not much bigger, but they are always a little inconvenient to carry than the previous ones, but relatively speaking, the lenses of these cameras are also larger, and the effect of light transmission is better. H2 and S5700 are very good choices, the effect is good, and there are still unsatisfactory places in operation and workmanship, but it should be said that it is still great value.

1. The coverage of the focal length of the telephoto camera is relatively long, but it is difficult to have a lens with good performance of the entire focal length at this price, so while controlling the cost, there will be gains and losses.

Second, the best comparison is to take a look at the real machine yourself, first look at the appearance, then look at the operation, and finally look at the shooting**, you should be able to choose your favorite model.

If you have a budget of 3000 yuan, it is recommended to take a look at Fujifilm S6500FD, which has a completely different atmospheric feeling from other telephotos.

I just saw an article about telephoto cameras.,It's recommended to take a look.,But this kind of article is just a reference.,The most important thing is the three looks just mentioned.。 Good luck finding the right camera for you, and if you have any questions, you can continue the discussion.

SLR is the abbreviation of single-lens reflex camera, and telephoto digital has two concepts, one is a long-zoom digital camera, and the other is a long-zoom digital camera lens. I don't know what you're asking: which is more reliable, or the extended zoom lens of a DSLR camera?

The lens of a single-lens reflex digital camera can be replaced, and the wide-angle lens is a wide-angle camera; An extended telephoto lens is a telephoto camera. Choose a full-frame digital camera with a professional telephoto lens, such as: Nikon lenses, for the D3X, it must be "reliable"; With 200mmf4 or is definitely not reliable.

If it's a long-zoom digital camera, it's definitely not reliable. Because, first of all, the caliber of the lens is small, the sense of lens is not strong, and the quality will not be very high, can it be "reliable"? It can be said that the longer it is, the less reliable it is.

The design of a long zoom digital camera is similar to that of a card machine, which has only one fixed lens, and a long zoom digital camera lens that is retractable. But as far as the body is concerned: the distance from the back of the lens to the CMOS is the same, so it is easier to do a wide angle and more difficult to do a telephoto.

As a result, some cameras have been changed to digital zoom instead of optical zoom. The meaning of digital zoom is that only the middle part of the CMOS is used, and everything else is discarded.

The size and quality of the images are reduced. However, it is more "multiple".

A telephoto digital camera is a model with a large optical zoom factor, and the larger the optical zoom factor, the farther the object can be captured. The main feature of telephoto digital cameras is that the focal length is changed by moving the lens inside the lens, and the benefits of telephoto come into play when shooting distant objects or when the subject does not want to be disturbed. The longer the focal length of the telephoto digital camera, the shallower the depth of field, the advantage of shallow depth of field is to highlight the subject and blur the background, so that the best shot is better, and more professional.

The representative models of telephoto digital cameras are: Minolta Z series, Panasonic FX series, Fujifilm S series, Kodak DX series, BenQ GH series, etc.

Nowadays, the optical zoom factor of digital cameras is mostly between 3 times and 12 times, which can bring objects from 10 meters closer to 5-3 meters; There are also some digital cameras that boast a 10x optical zoom effect.

In terms of the overall quality of the lens, in fact, the larger the zoom range, the worse the quality of the lens. The two most common problems encountered by the 10x zoom lens purity head are lens distortion and chromatic dispersion. The purple edge situation is more serious, and the ultra-large zoom lens is easy to produce barrel deformation at the wide-angle end, and pincushion deformation at the telephoto end, although lens distortion is inevitable, but a good lens will control the deformation within a reasonable range.
