Questions about Sony SLR. Sony DSLR camera history

Hungry... In the eyes of Japanese manufacturers, functions cannot be added indiscriminately... Because the Japanese habit is "what should be used for something, you should not add some fancy and unsuitable things to it", I want to add *** functions to digital cameras... Japanese manufacturer thinks it's a ··· At the beginning, there was no company to do this, and then it was because in order to expand the market (like the Chinese just think that I have more than one function to strengthen you a lot of "cost performance") to add it (in fact, the number is still not much), but to the single-lens reflex professional level of digital products, because the people who can afford it are rich or professional people, for Sony such a "newcomer", adding functions indiscriminately will make some potential professional customers think that they are messing around, which will be very troublesome... Therefore, it is normal to show your "professional ethics" for SLR cameras, and disdain to add photography functions to the camera to attract the attention of some professional consumers

Another point, as 1l said, SLR is only used to shoot still images... lzYou don't always think that a camera that takes pictures well will also have a good picture quality... These two functions are two different things when they are actually designed... Good photography doesn't mean good photography... Since there is no guarantee that the photography is good, Sony thinks it is normal that there is no need to add it... Compared to taking pictures, the addition of crippled photography functions will only be nondescript...

Clause. First, SLR cameras are mainly to take pictures Try to do the best static imaging is the purpose So the dynamic is omitted In fact, if Sony's SLR has a dynamic function, it is really nondescript.

Clause. Second, Sony's SLR is actually still very young Although it has merged with Carl Zeiss's factory, its own history is still too little Now Sony's SLR is mainly for entry-level Of course, Sony's SLR is still professional-grade Just like A900 is a good top product.

Nikon, Canon, and Sony have all discussed, for example, Sony's biggest regret is that there is no camera, and Nikon Canon's biggest regret is that there is no body stabilization.

This is from the brand point of view, from a small range, different models of the same brand, but also this one has a function that makes you greedy, and that one has another different function that makes you greedy, so that you look at it difficult to choose.

In fact, some functions are added to the root of a fuselage at the same time, which will not increase the cost much, even if it is added, ** improve it a little, everyone can accept it, but they just don't add it, deliberately. Unless it's the highest-end tens of thousands of full-featured models, if an entry-level or mid-range model uses all the functions, everyone buys this fully functional one, then they can't sell a lot of other messy models.

This leads to the fact that you look at this and want to buy that, buy that and want to buy this, and then you toss and turn, and your money is made by those Japanese profiteers.

You may not believe it, but Nikon's important component CCD is produced by Sony. What Sony lacks is CPU technology.

If the number of bodies of a certain DSLR makes people feel more than the lens, then the eight achievements are Sony. In 2006, Sony took over Minolta's SLR business, and after the release of the A100, in the following four years of 2007, 2008, 2009, and 2010, Sony released a large number of the following things.

2006 A100

The purpose is to announce that Sony, a major home appliance manufacturer, has entered the field of professional SLR.

2007 A200, A700, A900

A200 is used to replace A100, the main changes are the appearance and user interface, obviously missing a turntable, A700, A900 too, the latter two are mid-range and full-set models, the most eye-catching is its LCD screen, but the 920,000-pixel 3-inch LCD screen is the first, Canon Nikon was still stuck at 230,000 pixels at the time.

2008 A300, A350

The competition is not NC, S began to find another way, mainly adding a flip screen, the first LV function on the SLR, CCD pixels have also increased, especially A350 is worth mentioning, double CCD SLR, the design is very ingenious.

2009 A230, A330, A380, A500, A550, A850

Still not competitive, so Sony released a bunch of stuff on it. This should be classified, A230, A330, A380, the biggest improvement is to make the manual inside the control system, which can be easily queried in real time, and the fuselage is very small and light, which is commonly known as the mm machine, or the Airbus series, hehe. However, men basically do not accept these models.

a500, a550.In view of the characteristics of the previous model being sprayed wildly, the high sensitivity has been improved, and the in-camera HDR function has been added, and the A550 can be said to be the model that Sony has begun to turn over. At that time, A550+1680ZA was a very good choice, and it was also the most used in S at present.

A850, shrunken A900, but the reason why it sells well is: 10,000 yuan full width.

2010 A290, A390, A450, A560, A580, A33, A55, NEX3, NEX5

Still can't compete with NC, so Sony has basically given up on the MM machine at this point.

The A290, A390, and A450 combine the advantages of the A550 and make the high sense up as an entry-level low-end model.

A560, A580 has added a lot of practical functions on the basis of A550, and added ** shooting, A580 can be said to be the most powerful entry-level SLR at present, or maybe it is Sony's last traditional SLR.

NEX3, NEX5, the result of learning from Panasonic Oba was a great success.

Year 2011. a35, nex-c3, nex-7, a77

Sony does not have a DSLR, only a single battery. Sony's single electric and micro mirrorless have the following differences1Bayonet differences.

The mirrorless is an E-mount, which supports full-frame CMOS, a bayonet diameter of 58mm, a flange distance of 18mm, and an aperture ratio. Personally, I think that this bayonet may unify the rivers and lakes in the future. Advantages, better edge imaging but less costly; The production cost of large-aperture lenses has also been reduced.

The single electric is the A-mount (MD mount) inherited from Minolta. Nothing special to say, the lens group is richer than the e-mount, and the only mount that supports an automatic Zeiss head is a huge advantage for Sony.

2.The difference between stabilization.

Mirrorless mirrorless supports body stabilization, and single electric supports body stabilization. Sony has acquired Olympus, and perhaps in the future, it is possible that Oba's five-axis anti-shake technology will be used in its own mirrorless mirror, just speculation.

3.Reflector (semi-permeable membrane).

Monoelectric has one more structure to fix the reflector (semi-permeable membrane) than the mirrorless one.

4.So far, there is a full-frame A99 for a single battery, and a full-frame mirrorless is still on the way and has not been released.

Everything else doesn't make much difference.

First of all, the framing method is different, the SLR uses optical framing, and the mirrorless uses electronic framing. The second is the difference in the number of lenses, the lens group of SLR is rich, in the first type, there are more choices, and the number of mirrorless lenses is not as large as that of SLR, and the lens is slightly more expensive than SLR lenses.

Mirrorless is just a card machine that can change lenses.,The image processing technology and internal structure of the SLR are much more complex than the mirrorless.,Of course, the effect is much better.,I always feel that the mirrorless is a thing that doesn't enter the stream.。。

Sony now focuses on single and micro single key connections.

It's rare to have such a cheap telephoto head, but there is a 75-300 one, about 1100 yuan. There is no lens stabilization, no zoom motor, and it is not so easy to use. It is more suitable for ball games and shooting wild animals.

This lens is very slow to focus, and sometimes it does not achieve the purpose of autofocus, so it is necessary to rely on manual work. The choice of telephoto head depends on your subject, the 55 and 75 are two wide-angle ends that are about the same, and the 55 is more suitable for your framing. But 55-200 is not wide and long, it is better to buy an 18-200, and then change the standard head when shooting close-up shots.

75-300 is the telephoto head I hold to practice my hands, the most headache for me is that I am cautious and do not allow my hands to shake a little, otherwise it will be empty, and if I use it with a tripod, I can't achieve flexibility, and I regret buying it a little. That's all I can say, the 75-300 is good for shooting stationary subjects from a distance, and the 55-200 is more suitable for beginners than the former. Work hard, SLR is to fill the pit of dissatisfaction, if it is not a professional need, don't buy a telephoto head first, it is easy to be eliminated by Huai Chi himself.

I'll show you two of 18-300** I took a random shot in a hotel room in Hangzhou last year, about 3 kilometers away from the City God Pavilion.

18 ends on the left side, 300 ends on the right side.

The DT 16-50mm F lens is 16 elements in 13 groups, including 2 aspherical elements and 3 ED lenses, with a wide-angle end of 24mm equivalent (for a wider range of scenes) and a maximum aperture of 72mm. Coupled with the dustproof and waterproof design, and with an ultrasonic motor, the cost is much higher, and the imaging effect is better.

The lens of DT 18-55mm F SAM is 8 elements and 7 groups, including 2 aspherical lenses and 1 ED ultra-low dispersion lens, the wide-angle end is only equivalent to 27mm (the focal length of the wide-angle end is 1mm shorter, and the maximum aperture is only the wide-angle end), and the telephoto end), the diameter is only 55mm, it does not have a dustproof and waterproof design, and the feel is poor.

Photographic equipment is like this, you get what you pay for, two cents for two cents, and three dollars for three cents. DT16-50 is definitely better than DT 18-55. Of course, this imaging gap is not as big as theirs.

If you don't have bad money, it's definitely better to choose the former, and if you're sensitive to ** and have a limited budget. The latter can also meet general needs.

The difference is very big, whether it is workmanship or material, but from the perspective of photography, there is only one difference, the former is called a high-speed lens (bull's head), the latter is called a low-speed lens (dog's head), that is, the difference in the maximum aperture, but this difference will cause many differences, the biggest difference is the difference in caliber, the former is much thicker than the latter, the amount of light is larger, and you can choose a faster shutter speed in a darker environment, this difference is very important, it can be said that the latter is a travel head, shoot here and travel, and the amount of light in indoor shooting during the day is not enough, the former can do more, you can shoot indoors without the need for auxiliary light sources。
