Like using two cameras from the show motion by the camera body It is not easy to switch autofocus mode during the filming process. Although the operation itself is not complex, the photographer's eye has to be

To the photographic enthusiasts for detailed analysis to share the Canon SX60 HS adopted image processor and picture format. Analytical sharing: Canon SX60 HS employs DIGIC 6 image processors. According to the information provided, you will be able to understand the Canon SX60 HS using what image processor. Canon for SX60 HS equipped with the fuselage of the ceiling flash, so that even without professional lighting equipment can be photographed with the normal exposure of photo

relied on by the small aperture, but by fine-tuning the microscope. Note that the camera channel and the eyepiece observation channel should be consistent, that is, the most clear under the eyepiece is also photographed the clearest, so as to facilitate the photo. When taking pictures, the camera should choose the maximum aperture and wide angle. Do not use telescopic zoom, which makes the field of view sm

drilling is 0.25mm (10mil). Generally, the aperture design is greater than or equal to 0.3mm (12mil ). If it is smaller than this, it is just 0. 25mm, the people in the board factory will definitely look for you. Why? Find the answer in (5! (3) The minimum slot hole diameter is 0.25mm (10mil).

smaller than that of the precision lens, and the stereoscopy decreases. Proprism is easy to manufacture and cheaper than Ridge Prism of the same optical quality. Roofprism is a compact, dual-cylinder lens that is usually used for compact dual-cylinder mirrors because it is small in size and can place the objective lens and the eyepiece in a straight line. Compared with the proprism, The Ridge Prism has two main disadvantages: one is the loss of lig

but does not stop, and the screen is stopped on the "set gap ". Solution: 1> press the "reset" key to reset the system. 2> open the wind shield and enable the left and right pressure plates respectively. Perform the following checks in sequence: 3> check for fiber breakage. 4> check whether the optical fiber cutting length is too short. 5> check whether the fiber slot matches the optical fiber. And perform corresponding processing. 5. The optical fiber can be properly reset. When the gap is set

. Even if it passes through, there will also be hidden risks. As the number of these hidden risks increases, the six types of performance margin will be minimized, and faults will occur.Another important note is the bending radius of the cable. Avoid excessive cable bending during cabling, because this will change the Layer Space of the cable's internal line. When the tension is too large, the twisted line will be released to form a mismatch impedance, so that the return loss performance is not

I. Adapter 1. Briefly describe that the recently learned GridView and Gallery both use the Adapter and find it very important. I searched for information about the Adapter on the Internet. The vast majority of android applications are written in JAVA. Adapter is a special design pattern in JAVA to combine two unrelated classes. For example, if the pipe A is 25mm, and the pipe B is 40mm, assuming that the pipe thickness is not counted, how to connect t

However, for ar3200+ printers, such as switching to a non-proprietary driver, can cause serious "side effects": first, poor print quality; the second is the printing effect and settings do not match, the core position of the overall move down.
