The world of photographic equipment is great and varied. And naturally the desire of many people from the very beginning to know him better. Among other things, it is worth finding out the main features of full-frame cameras.
What it is?
About full-frame cameras at least once heard anyone interested in photographing. A number of enthusiasts (both professionals and lovers) leaves enthusiastic reviews about them. To understand what the full frame means, you need to pay attention to the principle of obtaining an image. In the digital camera, the matrix captures the light from the moment the shutter is discovered and up to its final closure. As a “sensor” before the onset of digital era was used was used, in advance exposed frame.
The size of the frame in both cases is not so easy to control – It definitely corresponds to the magnitude of the photosensitive part of the chamber. Traditionally, a full frame is a picture of 35 mm, since it was the most common film format that was. The creators of digital technology simply copied this size. But then in order to save on matrices, their dimensions began to reduce.
Even today, the manufacture of a full-size photosensitive element is very expensive, and often manufacturers will heat up such equipping their models.
Advantages and disadvantages
An obvious plus of a full-frame camera is an increased detail. Since light on a large matrix gets more, clarity pictures also increases. You can not doubt that even relatively small items will be drawn well. The size of the viewfinder increases, which simplifies, speeds up the actions of the photographer. This circumstance allows you to increase the resolution of the pictures.
Part of the manufacturers Instead of adding additional photosensitive points, the dimensions of the already used pixels are increasing. Such a technical solution increases the photosensitivity of the matrix. Therefore, pictures will be brightened with the same lighting. But larger pixel size guarantees a significant increase in sharpness.
Lack of “Zuma” effect and a small severity of digital noise also testify in favor of full-frame cameras.
What differ from the incomplete?
But in order to better understand the essence of such models, it is necessary to study the difference between the full-frame and incomplete camera cameras. Contrary to popular opinion, the full frame is better not always. This is definitely a useful thing, however, she reveals its advantages only in skillful hands. A large format has a greater potential dynamic range. Twice a large light capacity helps to improve the signal ratio and noise by 2 times.
If the ISO values are the same, the full-frame sensor is less “noum”. If ISO is less, notice the difference even experienced photographers and experts will be much more difficult. And when the basic ISO is used, at the level of 100 units, the only real advantage of the full frame is the ability to efficiently pull out the shadows during subsequent processing. In addition, only models released at one point and a more or less similar element base can be directly compared.
Improvement of technology affects and incomplete chambers, modern samples of which can be better than old devices with a large frame.
Snapshots with enormous ISO values can really interest only real professionals who know how and why do they do. But ordinary people are unlikely to be able to determine the difference in one or two dynamic steps. Therefore, it’s not worth afraid of buying a non-changing chamber – it almost always justifies expectations. As for the depth of field, the effect on it the values of the frame is only indirect character. Need to take into account the size of the diaphragm.
Full frame devices are somewhat better when separating the main object from the background with insufficient depth of field. Such a need arises when portraits are removed. But everything changes when it takes a frame with the same sharpness up to the horizon. Because in the landscape pictures more correctly use Crop Crop Crop Crop. With strictly equal conditions, their enlarged real sharpness is quite attractive.
It is also worth considering that The choice of lenses for full-frame cameras is very large. They are supplied by many outstanding manufacturers. But the incomplete chamber cameras have a good lens much more difficult. It’s not only a smaller assortment, but also in much more complex general principles. Suffice it to say that many photographers put in a dead end the calculation of the equivalent focal length. In addition, full-frame models are larger and harder than reduced versions.
If it is still decided to use exactly the cameras with a full frame, then you need to pay attention to the mirror models. Special mirror has a lens. The installation angle is always equal to 45 degrees. The role of the mirror is not only sight, but also getting the optimal focus.
It is from it that part of the light stream is redirected to focus sensors.
When the mirror element rises, the characteristic sound is distributed. Vibration at the same time can appear, but it does not reflect on the picture. The problem is that with high speed shooting, the mirror is experiencing a significant load. But the cost of the mirroring device is more profitable than the cost of many mirrorless models. Design worked very well.
It is worth noting that Compact full-frame devices also exist. Such models are in the Sony assortment. But a good example is also served by Leica Q. Similar devices work perfectly in the hands of professionals. Compactness does not prevent the decent quality of the pictures and equip the devices with high-quality “stuffing”. Of course, there are digital cameras with full frame.
Rating the best models
List of cheapest full-frame cameras deservedly opens Canon EOS 6D. Resolution reaches 20.2 MP. Provided high-quality optical viewfinder. Possible video shooting with 1080p quality. There is a serial shooting option with a quality 5fps. As an alternative can be considered Nikon D610. This inexpensive camera has a resolution of 24.3 MP. As in the previous version, an optical viewfinder is used. Serial shooting quality increases to 6fps. Installed a rigidly fixed screen with a diagonal of 2 inches.
Undoubtedly, the useful properties of this model are the presence of a pair slot for SD cards and an increased level of protection against moisturizing. But it is worth indicating the impossibility of working with wireless protocols (it is simply not provided). But there is a quiet photograph option at a speed of 3 frames per second. 39 basic points were entered into the system of automatic focus. As a result, it turned out quite affordable and more accurate, from a technical point of view, the device.
Average price segment
The expected representative of the Top full-frame cameras is Nikon D760. This digital device with DSLR matrix has not yet entered the market, but it is looking forward to it. Actually announced the continuation of the model D750. Of the most likely add-ons it turns out the presence of shooting as 4K. An increase in the number of focus points is also expected.
A good reputation has Sony Alpha 6100. The device was equipped with an APS-C matrix. In favor of this model indicates a very fast focus. Users will delight automatic focusing in the eyes of animals. Touchscreen slope angle reaches 180 degrees. The screen itself is made using TFT technology.
In comparison with other models, seriously wins Nikon D850. This version is positioned as a good assistant for professional shooting. DSLR matrix will not let go in any situation. A video recording is possible in the resolution of 4k, which is very good for the 2017 model.
But it is worth noting that when shooting in poor lighting due to ultra-high resolution, strong optical noises appear.
A worthy completion of the review will serve Sigma Fp. Designers have provided an aluminum housing that guarantees increased reliability in adverse situations. Sensor with a resolution of 24.6 MP has rear backlight. 4K resolution is available even when changing 30 frames per minute. Continuous shooting is possible in modes up to 18fps.
How to choose?
The most important thing is to immediately decide how much money can be spent on the purchase of the camera. So choose amateur or professional device class. Among household models have its own separation – simple automatic and mirror versions (which require complex settings). You can use mirror cameras only to people who understand their device and nuances of work. Those who do not have complex skills, it is worth choosing an automatic chamber.
Do not focus on the “most recent” devices. All the same, they will be outdated after 2-3 months, and they will not surprise anyone. Marketers diligently spinning this moment. But also acquire devices released over 4-5 years ago, it is also unlikely to be rationally.
The exception is the most successful models that are treated with many photographers.
The number of megapixels (resolution of the picture) for professionals is not too significant. They remove anyway on a technique for which the difference in such a characteristic is low. But for home cameras, accounting for this parameter is quite appropriate, especially it is relevant when printing pictures of large formats. Beginner photographers can safely ignore the mass and dimensions of the device.
But those who plan to do long-term or reportage, away shoots, it is worth choosing as easy and compact modification.
Gathering at least occasionally shoot a video worth asking for the presence of a microphone. It is also desirable to check his work right away in the store. If you need to choose a flawless quality device, it is worth paying attention only to Nikon, Canon products, Sony. All other brands can also do high-quality equipment, but the Three Grand Products have a deserved inaccessible reputation. And another recommendation – try the work of the camera with different lenses, unless it is possible to change them.
