The  BG-S1 Battery Grip for Sony A77, A77 II & A99 II Digital Camera from Vello is a battery grip designed for use specifically with the Sony A77, A77 II, and A99 II (not original version) digital cameras, and accepts one or two NP-FM500H lithium-ion batteries. With two batteries installed, your shooting time is effectively doubled. Moreover, when one battery is drained, it can be removed and recharged while you continue shooting with the other battery.

The design of a battery grip offers a comfortable and secure way in which to hold your DSLR, especially in the vertical position. It will reduce wrist and hand fatigue when shooting vertically for extended periods of time. The BG-S1 has an alternate shutter release button designed for ergonomic access when shooting vertically and anti-slip rubber gripping to further improve handling. In addition, the BG-S1 has an alternate AF start button, smart teleconverter/focus magnifier, Fn/image rotation button, AEL/slow sync/image index button, AF/MF/enlarge button, exposure compensation buttons, a Multi selector and a main dial. It also features a tripod socket, a strap lug for attaching a hand strap to the camera and a convenient internal slot to fit the camera's battery door when the grip is attached. A battery tray is included to house the NP-FM500H batteries within the grip.

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
