YONGNUO YN-468II - Phụ Kiện máy ảnh ( Đen )

Specification:Improvements in this 2nd generation YN-468 II of this top-selling flash unit aim at the weak spots of the 1st gen model YN-468, our engineers are paying attention to what our customers are saying.Here are the upgraded features:a), Improved New Battery CompartmentThe 4 batteries are now all in a row with a latch that flips open. This looks like a much better design now, no more acrobatics required for a battery exchange.b),Improved Optical Slave Sensor ( Located on the front side of the flash, underneath the red plastic screen )"S1" mode --- it is used with manual flash or Studio flash."S2" mode --- it is designed for digital TTL flash. The special thing about this mode is the ability for detect the ingnore the tiny pre-flashes sent out by digital TTL systems before the shutter actually opens.The range is a little longer and the sensitivity is better than the 1st generation.c),Improved (Laser) AF Assist LightWith the much improved AF assist light of YN-468 II, it can help the camera find focus in darkness, and there's a bright red pattern projected now which helps much better with low-contrast subjects althoug it's still limited to the center AF field. Our engineers also moved away from a simple LED but use a laser-based system which explains the clearness of the pattern, as well as the high range of the beam.d), PC Sync PortWe built a PC sync port in the side of the YN-468 II, you can not only trigger the flash through the flash foot, or with the optical slave modes, but aslo through a PC Sync Cable.e), Improved Buttons Design It is sensitivity and better feeling to control.And here are some other features:1), TTL modeThe metering system of this camera will detect flash illumination reflected back from the object so as to automatically control flash output in this mode. In this E-TTL mode, you can also make compensation of flash brightness with the " Output contral knob" within the range of ±3 ev, with the precision of 1/3 ev. ( Only with this feature the camera-flash combination can give you correctly exposed flash photographs automatically.)E-TTL can be set on the flash although the display just says “TTL”, but it works with E-TTL I and also E-TTL II camera bodies.2), Auto ZoomThe flash speedlite will move forward and backward with the changes of lens focus to suit different illumintion zones when it is mounted on the camera which supports E-TTL Function, the zoom range is 24mm - 85mm. You also can set the focus position for the light head manually by pressing the mode swithc button + Power button.3), Multi ModeIt's the strobeflash mode, the flash light will output the power, flash frequency and time flash you have set.4), M modeYou can set flash luminance as per your favorite, luminance level will be displayed by luminance indicator. When taking photos, you only require setting the flash luminance, adjust the camera and press the shutter, the flash light will flash under the camera synchronous signal.5), S1 ModeIt will work with the first work of the master flash synchronously in this mode, with the result consistent with the use of radio slave. ( When you use this mode, your master flash should be set at manaul flash, the TTL flash system with pre-flash function and the red-reduction function with multiple flashes should not be used.)6), S2 ModeIt is very similar to S1 mode, but it can support the master flash in TTL mode. In particular, if S1 mode can not have correct and synchronous flash with the inbuilt flash, you can try to use S2 mode.Advanced Application:a), Multi-Lamp Lighting Applicationb), Exposure Bracketing ( FEB)c), Use Wide-angle Diffuserd), Rear-curtain Synce), FE Lock ( This function can only be available when your camera supports it, for the setting of FE lick, refer to your camera manaul) f), Application of AF LEDg), Exposure Compensationh), Feflection Flashi), Use Reflection Board to take photosParameters:Guide Number 33Flash Mode TTL / M / Multi / S1 / S2Circuit design Insulated Gate Bipolar Transistor (IGBT)Zoom Range Auto, 24mm, 35mm, 50mm, 70mm, 85mmVertical rotation angle -7~90 degreeHorizontal rotation angle 0~270 degreePower 4 X AA size Batteries ( Alkaline or Ni-MH are usable)Lighting times 100 - 1500 times (with AA alkaline batteries)Recycle Time less than 3s ( AA alkaline cell used)Color Temperature 5600KFlash Duration 1/800S - 1/20000SFlash Control TTL auto flash or manual level 8 light quantity output contral with 0.3 stop incrementDimensions 60 x 72 x 172mm(extended state)Net Weight 300gAdditional features FEB, FEC, FEL, Automatic zooming, Rear-curtain SyncSuit for Canon 1100D 1000D 600D 550D 500D 450D 400D 350D 300D 50D 40D 30DYou can use this flash with Yongnuo flash Trigger RF-602, RF-603, CTR-301 PPackage Including:1 x YN-468 II Flash Speedlite with Metal Hot Shoe 1 x Mini Stand1 x Flash Diffuser cover ( for free )1 x Manual in English and Chinese
