II. Introduction to Ricoh gxr
Ricoh GXR interchangeable lens imaging component Digital camera system is the smallest and lightest digital camera in the world, which is easy to carry. It has a high-hardness magnesium alloy body and a number of lens imaging components that can be changed according to different shooting scenes. GXR has a variety of custom buttons and a brand-new direct button, which allows photographers to see many current settings at a glance. It can also be used to quickly complete complex shooting settings. Arrow keys with the same function as GRDIII, three sets of my settings, ADJ lever and function buttons make GXR more powerful in operation. Ricoh GXR adopts a 3.0-inch, 920,000-pixel high-resolution VGA LCD screen. The camera's high-resolution LCD screen has a wide viewing angle and high contrast. The display screen has anti-fouling fluorine coating, anti-scratch hard coating and anti-reflection coating, so the screen can be seen well even in bright sunlight.
Third, Ricoh gxr evaluation
Wide-angle lens is a necessary lens for many landscape photographers. With its large aperture and unique lens structure, wide-angle fixed-focus lens can obtain greater magnification by shortening the shooting distance, and at the same time, it has a wider background and good blur effect, which is a sharp weapon for shooting humanities and landscape themes. As the fourth image module of Ricoh GXR system, Ricoh grlens 1228 MMF 2.5 still uses grlens 1250 MMF 2.5 macro as the lens material. And specifically for the problem of image quality degradation at the edge of wide-angle lens, this module gives priority to solving this problem in lens design, ensuring high image quality while ensuring that the image quality at the edge will not deteriorate.
Judging from the real shot proofs, the imaging quality of grlens 1228 MMF 2.5 is the same as that of grlens 1250 MMF 2.5 macro, and the imaging effect is almost the same as that of mainstream digital SLR products, which reflects the advantages of fixed-focus lens in image quality. In noise control, grlens 1228 MMF 2.5 has a very good performance, and ISO is highly used, which will be analyzed later.
From the appearance, Ricoh grlens 1228 MMF 2.5 is only a shortened grlens 1250 MMF 2.5 Marco, and there is nothing new. After all, it is not so realistic for the modular system to make any breakthrough in appearance.
Ricoh grlens 1228 MMF 2.5 has a volume of 68.757.950.4mm and a weight of about 2 10g. The volume loaded on the GXR fuselage is113.9X70.2x55.6 mm and the weight is about 4/.
Ricoh grlens 1228 MMF 2.5 adopts the design of 6 groups of 9 lenses, 2 double-sided aspheric lenses and 1 ED lenses. Moreover, due to the small number of lenses, even ordinary lenses are all polished with high lenses, and the materials are very luxurious (the same as GRLENSA 1250mmF2.5Marco), which greatly ensures the imaging quality of the module.
Ricoh grlens 1228 MMF 2.5 has 1 1 aperture blades, and the aperture shape is circular, which can shoot beautiful circular spots. In addition, Ricoh grlens 1228 MMF 2.5 module adopts mechanical shutter, but this module does not adopt independent mechanical shutter, so the aperture blade of this module also serves as shutter. The shutter speed of the module is 180-3200 seconds (except for the B-door function, no product on the market can have such a strong long exposure). However, due to the combination of aperture and shutter, the shutter of 1/3200 can only be realized if the aperture value is greater than F7. 1. At the maximum aperture, the maximum shutter speed is only11000 seconds.
According to the test, the highest definition of Ricoh grlens 1228 MMF 2.5 module is between F4-F 1 1. However, even if the maximum aperture is used, the image definition is still not low, but the edge imaging is slightly weak, but if it is reduced a little, F2.8 F5.6 is the best aperture for the lens, and the imaging is very sharp in both the central part and the edge position. When the aperture is less than F 1 1, the image quality will decrease, but it is not obvious. Generally speaking, the performance is very general.
The concept of Ricoh GXR is actually good. In the early stage of ensuring high image quality, the volume of the fuselage should be minimized without affecting the shooting feel, which is incomparable to all single batteries at present. However, the price of GXR fuselage+module can often scare away consumers. After all, more than 3,000 yuan of fuselage and several thousand yuan of module purchase funds are enough to buy a powerful digital SLR and a good lens. Therefore, if GXR system does not work hard on price now, it will be difficult for this relatively alternative product to open a bigger market.
Above, we introduced several aspects of Ricoh gxr, including the quotation, introduction and evaluation of Ricoh gxr. We know that Ricoh gxr is a camera with excellent performance in all aspects. It not only has a classic appearance and high recognition, but also has a great competitive advantage in performance parameters, which makes Ricoh gxr stand out in the fierce camera market and has a large number of loyal supporters. Friends who are interested in buying Ricoh gxr may wish to refer to the above information comprehensively and make purchase choices according to their own budgets and needs.
