1. The battery compartment is very difficult (!!!) and pull einzusetzten again. Under professional working conditions, points of a scheduled photo session an absolute no-go. Especially when it comes down to it and have to go quickly and that is in the photo, unfortunately, practice almost always the case, one is disturbed and there is a great danger that something breaks inside.
2.The big bright release button can be removed only with photo retouching from the photo again. Really discreet, secret initiation of the camera is thus almost impossible! The original can be much better to hide in your hand when you press.
3. The release rate is a touch slower, not really much - but it can make all the difference.
I also besitzte the original and very often had in practice I have the exact comparison.
So who can live with these Einschkränkungen - can strike here and previously test the battery and if necessary switch. Otherwise, prefer to buy the original, because the price difference is too small for it.
