2, these two kinds of Internet devices are not the same thing. 3G network card is to receive carrier signals (like mobile phones, but can not make a phone can only surf the Internet), wireless router is to access the cat output signal and then transmitted to the computer, tablet computer, mobile phone, etc.
3,First of all, it is not that you can surf the Internet with mobile wifi, it is just a similar router can carry on the network card, so you also need to install 3G card to be able to surf the Internet normally. The operating panel information from left to right is 3G signal light, WIFI signal light, battery indicator and power switch.
Want to change the screen better phone, I recommend you choose vivo x80, vivo X80 adopts Samsung 78-inch E5 super screen; The height is about 1695 mm, the width is about 723 mm, and the use is very good. This is a Zeiss image, Tianji 9000, self-developed chip V1 advantages of high-quality screen mobile phone, very like, very convenient to use, feel first-class, good appearance level, comfortable grip, with beauty, photo effect is also good.
Samsung Galaxy S22 Ultra Samsung's screen will always be its biggest selling point, and the Samsung Galaxy series is to hold back on the screen. Samsung Galaxy S22 Ultra screen material, brightness, color, color and other aspects are far beyond the external screen.
If you are a game party, want to change a good screen mobile phone does have a lot of recommendations, today Xiaobian to recommend a few. Combined with dToF's 64-dot laser focusing system and Xiaomi's self-developed "Night Owl algorithm," the Mi 11 Ultra has the image power of a professional camera. Overall, the cost performance of the Mi 11 Ultra is higher. If you want a better screen, the experience is the ultimateThe safety of external forces.
2, personal preference Canon. I recommend the 60d. It's a mid-range model, after all. The 600 has the same processor and sensor as the 60. But other hardware configurations are different. For example, the 60d has a shoulder screen, is an eye flat pentaprism, magnification and field of view are better than those two models. Be more professional. Basically, the quality of an SLR configuration is the total number of shutter times, shutter speed, viewfinder, magnification, processor and sensor.
3, Nikon D90 only 720P video, and can only focus manually, Canon 60D is 1080P fullFor HD video, hold down the AF-ON key to focus automatically. The Canon 60D can also adjust the dark Angle according to the lens and so on, the Nikon D90 does not. To be honest, although Nikon D90 has a shoulder screen, pentaprism and metal skeleton, it is still essentially an entry-level SLR, of course, it is true that it is a very classic advanced entry-level SLR, and it is not easy to sell for several years.
4, D90 added video function. D90 internal flash wireless flash. The D90 LCD screen is large and comfortable to look at. The D90 has a fuselage focusing motor, while the D60 does not, limiting the use of many lenses. The reflector vibrates, very lightlySlight vibration, quick recovery, sound good. The D90 is bulkier and more comfortable for men to hold. .D60 doesn't work with a real handle. In short, the D90 is the mid-end SLR, the D60 is the entry level, the gap can not be measured.
Speed ISO 100 to 6400 is adjusted in steps of 1/3 EV. It can also be set to step size adjustment of 0.3, 0.7, 1 or 2 EV (equivalent to ISO25600), highAutomatic ISO speed control at ISO6400. File format NEF (Compressed RAW) format; JPEG; MOV short film. Storage media SD memory cards, SDHC, and SDXC memory cards.
At the same time, in low light environments and higher ISO, the Nikon D5000 does not appear significant noise. The set lens Nikkel AF-S18-55mm/F5-6GVRDX used in shooting, like other home sets, has a certain macro capability, and with the larger frame of the SLR camera, we can easily use it to shootTake photos with a clear depth of field.
Speed up to 25600, coupled with the new Expeed2C image processor, high ISO noise control capability is worth looking forward to. The battery life has been increased to more than 600, and the Nikon SLR is the most power-saving, which has a great advantage over Canon and SONY. Disadvantages: The automatic focus is still 11, which is not as good as SONY's 15, and the gap between intermediate SLR is larger.
When shooting moving objects, the focus mode must be adjusted to the motion focus mode AF-C, and the focus is not clear and easy to blur. There is also the adjustment of ISO speed, but it is best not to exceed400, or the photo will be too noisy. In fact, the easiest way is to take sports photos on sunny days.
