At what price level of camera do you think you should switch from a Nikon grip to a compatible grip? :shrug:
I ask because people were saying the same thing about the D300, which was just £1k, and compatible grips.
I rarely use my grip, so there was no way I buying a Nikon grip. (for D300) :nono:
People make the same argument with compatible batteries too.
Nikon batteries, in fact most manufacturers own brand batteries, they are overpriced for what they are imho. As long as the compatible items work just as well, or close to just as well, then I'll go for the cheaper route. For those that want to, and can afford it, please carry on buying the expensive stuff, it may help keep the manufacturer profitable.
If I didn't have the cheaper option for the grip, then I wouldn't have got one for the amount of time I use. So Nikon didn't lose any money from me going the compatible route. :shake:
The problem you may have with new gear like the D800 is that they may change the design of grips and batteries from previous models, and there may not be compatible items available on release.
