What are the choices of full-frame cameras for different purposes?

Recommended full-frame cameras for human documentaries (entry-level): Canon EOS 6D and Sony A7.

Recommended model (fever grade): Sony RX 1R

Documentary photography needs quick response, snapshot ability and mobility. Because of the oppressive feeling brought by large-volume equipment to the subject, it is not suitable to choose Quan Huafu SLR camera. A camera like Canon EOS 6D has both the mobility and portability similar to APS-C format products and the high quality of Quan Huafu, so the choice of documentary photographic equipment is also worthy of consideration. Quan Huafu's biggest advantage is that it is very convenient to choose a 35mm fixed-focus lens, while APS-C frame needs a 24mm lens to get a 35mm viewing angle, so it can't guarantee the image quality and depth of field effect.

Sony A7 is the best interchangeable lens camera in Quan Huafu, because it is equipped with an FE 35mm f/2.8 lens. The phase detection point is on the A7 sensor, and the focusing speed is acceptable. Just not as fast as the SLR independent focusing module, EVF will be delayed, which may have some adverse effects on human body capture. Therefore, it is recommended to use this camera as an alternative.

Sony RX 1R, as the only 135 Quan Huafu card camera, adopts Zeiss Sonnar T* 35mm f/2 lens, which naturally becomes an artifact for humanistic photographers. 35mm humanistic focal length and low-key modeling determine that it can exert all its strength in humanistic shooting. The only disadvantage of this camera is that it has no price advantage, but if you like humanistic photography and 35mm focal length and want a small artifact, this Quan Huafu card machine may be the best choice.

Recommended full-frame camera for landscape photography (entry-level): Sony A7

Recommended models (fever grade): Nikon D800/ Nikon D800E, Sony A7R.

Sony A7 is a good choice for landscape photography. As a mirrorless camera, its focusing system is relatively weak, but landscape photography is generally a slow shooting activity, and the focusing speed is relatively low, which is precisely the best stage for mirrorless cameras to develop their strengths and avoid their weaknesses. Portability is the most prominent advantage of Sony A7, and EVF's WYSIWYG function is also more suitable for landscape photography. However, the current lens group seems to be slightly insufficient, especially the lack of support from native FE super wide-angle lens, which limits its performance in this field.

Nikon D800/D800E has a higher sensor resolution, and it also needs a higher investment in lens matching to bring the sensor level into play. With the right lens, 36.3 million pixels and no low-pass filter technology, it can bring a completely different shocking shooting experience. Fixed-focus lens is not recommended, because taking landscape photos with fixed-focus lens requires very high composition skills of photographers, and it is not suitable for photographers who have just transitioned to Quan Huafu.

Sony A7R has a 3640 Wan Chao high-pixel Quan Huafu sensor and an electronic viewfinder of 0.5 inches 1024? 768 organic light-emitting diode electronic viewfinder, high resolution brings better viewing experience, but obvious color noise cannot be avoided at high sensitivity. If you want to use it flexibly in landscape photography, it is recommended to consider changing the lens. Fortunately, users can choose the best lens in each focal length to match this fuselage, which is an advantage that other brand users cannot enjoy.

The principle of full-frame camera The film size of traditional camera is 35mm, the width is 35mm (including the punched part), and the photosensitive area of 35mm film is 36 x24mm? . When converted into a digital camera, the closer the diagonal length is to 35mm, the larger the CCD/CMOS size will be. In SLR digital cameras, many of them have CCD/CMOS dimensions close to 35mm, such as Nikon D 100, and the CCD/CMOS size area reaches 23.7 x 15.6, which is much larger than consumer digital cameras. The CMOS size of Canon EOS- 1Ds is 36 x 24mm, reaching an area of 35mm, so the imaging is better. We'll call it Quan Huafu.
