Mine is 23, still waiting I don't know when the next shipment will be, again slow to answer...
Here's manufacturer's comments based on the xitek forum user's experience:
Frequently Asked Questions:
1. out of focus: I am wondering why the most out of focus say ran backward, the actual test is more ahead of him, only the individual ran backward (F29 can be corrected), from the principle ahead of him much more likely to, so I guess it is the problem of the test method, contrast focus is the face of coke, need to focus around many pixels to calculate contrast and phase-point AF SLR film ruler method is not feasible, then the entire focus frame, only one line to become a strong contrast, such is difficult to judge the focus frame area is the focus, so really strict test method is 45 degree tilt of the focus target, and then camera as vertical as possible to shoot a target, a target placed below the ruler becomes clear before the race or after the run. But the most simple and feasible way is to shoot facing the computer screen with text, you can zoom in or observed the moiré to determine the focus. Different body focuses on the accuracy of a difference, but in addition to the NEX-3C outside, is not very different, the test body NEX-3C NEX-F3, NEX-3N, NEX-5C, NEX-5N, NEX-5R , NEX-6, NEX-7.
2. For focusing the success rate of many of my friends are saying the G28 is hard to focus my test also verified this statement, G35, G45, G90 focusing success rate is still very high, and the more telephoto focus the higher the success rate, the more it can use a smaller aperture to focus, this is mainly with the rate of change of the contrast, the rate of change of the contrast higher focus, so using the G28 must use the maximum aperture focus, the focus area freedom of choice point, as far as possible choose contrast strong focus on a subject, so you can increase the success rate, and sometimes does not appear green box appears only green dot focus is accurate.
3. Metering: This is a headache, because the NEX the early models (NEX-3C, NEX-F3, NEX-5C, NEX-5N) no shutter AEL turn off the option, we automatically mount in half press the shutter to focus, when the body does not turn off the shutter AEL exposure have been identified, if the focus and then close the aperture will be less exposed to exposure must be accurate the fuselage aperture and lens synchronization, individual reaction of friends small aperture shooting overexposure, which I can not find a reasonable explanation.
4. lens assembly and disassembly difficult: this is indeed a mistake on this design, there is no any good solutions can only tell you that with two fingers, the index finger to hold the release button at the bottom of the thumb to press the button at the top of so that it is easier to release.
5. Related crashes: this problem is relatively complex, there is no way to understand why, so please frequent crashes a friend contact our customer service to explain the situation, can also be sent over for testing.
6. 3C and 5C playback because 3C and 5C in power saving mode during playback will jump out of the playback interface reset again, for compatibility 3C and 5C transferred to the body aperture F22 time you press the shutter switch to compatibility mode and then shut down and then boot on OK, and want to return to power saving mode can be used F26 Repeat the above steps on the back. Compatibility mode will increase the standby power consumption. The power saving mode (factory)
7. For fine-tune the focus
F29-F45 is used to adjust the focus, F29 focus moved forward, F32 to factory default, F36, F40, F45 will focus set back operation: Set the aperture of the fuselage, the time you press the shutter confirm the focus focus after changes . This setting will be recorded in the mount, remove the lens mount is retained. ...Show more →
