Having found myself wanting a vertical grip for the Nikon D800 and not wanting to pay the ridiculous price for the Nikon branded grip,
I found the DTSE grip on Ebay from a seller in China
The grip comes complete with a non branded EN-EL18A battery and the battery door to fit the grip.
Two battery trays are supplied with the grip, one for the EN-EL 15 and one AAA battery tray.
Reportedly the trays and batteries are interchangeable with the original Nikon grip.
Along with a mains charger the EN-EL18A battery insert comes a car charger also which is a welcome accessory indeed.
The original Nikon battery has a capacity of 2000 mAh (10.8V), but the DTSE clone battery has a 3900 mAh (11.1V) capacity.
When I tested the battery and grip the video function of the camera does not work, but live view shooting does.
I have seen reports of
neither operation working with this grip when the clone battery is inserted.
DTSE D800 MB-D12 Grip
Thankfully all operations function fine when using both the EN-EL15 battery in the grip or the AAA tray.
This leads me to assume that the clone battery is perhaps over or under powering the live view section of the camera.
All in all though I find the DTSE Vertical grip to be a good substitute for the Nikon MB-D12 grip.
I would recommend this grip as a fine alternative.
The build quality is good and it appears to be well made, the grip matches the body mottling of the D800
It also has the metal strip inside for tripod mounting. the controls all function a they should do and feel positive in use.
The locating pin is made of metal the same as the original.
The only thing that does not seem as good as it could be is the tightening wheel this is because it
remains slightly loose to the touch when the grip is fully tightened onto the D800 body.
I have found that when an EL15 A is inserted in the camera while using the grip, the live view and movie mode functions
both work as expected, when powered from the grip with the clone EN-EL18.
The battery life of the supplied clone EL-EN 18 is proving to be excellent.
