Hey there
i have bought various third supplier batteries and have found out that its a problem with the high capacity batteries on my leaf aptus22
during the shooting it seems like that the weight of the battery is to much for the holding mechanism and there are short power outs which results in a weird behaviour of the back, it takes pictures, it also displays them but don´t save them... thats why i use the sb-160 now... i got some from an HK ebayer which are really stiff on the back, i need quite much force to get them in but now the fit like glued
no power outs anymore, i do have 4 of them now and thats enough for a quite long time...
search on ebay, don´t take the cheapest avaible and give it a try
