Es gibt übrigens bereits einen Nachfolger mit acht (statt vormals sechs) Mignonzellen für eine angeblich verbesserte Blitzladezeit, den Yongnuo SF-18, den es ebenfalls in drei Varianten für Nikon (SF-18N), für Canon (SF-18C) und für Sony (SF-18S) gibt (wobei ich die Sony-Variante noch nirgendwo gelistet gefunden habe).
ZITATSF-18 is an improved version of SF-17, it has faster recycling time and a newly designed layout.
Humanized Design --- Easy to carry and convenient to maintain for providing with a special leather protection case available to be held on the waist belt or backpack as well as to prevent the power leakage. The connecting plug invites the anti-wrong inserts design that can avoid the flashlight system from being damaged due to a miss-operation. Screws are also provided for fixing it on the tripod mount.
Excellent Performance --- It is proved that the recycle time can be reduced to less than half of the original and the flashes increased more than double of the original by using the external battery pack. And it is also proved to be very suitable to be used in a continuous flash condition.
Wide Use --- Before used with the Canon, Nikon, or Sony flash light via the difference connecting plugs, 8 new AA batteries (same battery type as the flash unit) need to be inserted into this product. In this way, it can greatly strengthen the flash light working ability. Obviously, it is the best choice for the professional photographers or fans.
Compatible with:
580 EXII, 580 EX, 550 EX, MR-14EX, MT-24EX
Cautions:
1. The battery power is likely to lose due to reasons, e.g. environment temperature or long time storage, so the battery selection is very important and needs to be careful. And it is necessary to replace the battery if the power keeps displaying low.
2. Manganese batteries with low capacities, batteries of difference brands, with difference capacities, or of new & old mix-ups are not suitable to be used here, for it will greatly affect the recycle speed and the flashes. It is recommended to use the high-capacity alkaline, Ni-MH or lithium batteries so as to guarantee the flash light using effect.
3. After 20 continuous shoots, it is recommended to take 10mins break, for the overheat caused by the instant discharge of high current for flash will cause damages.
4. Do not disassemble this product without permission, and please contact with the dealer if there any problem. This product is non-waterproof and should be used in an environment with a temperature of 0C°-40C°.
