The 54S has been my back-up back. Its appears like new. It has a perfect tight fit to the Hasselblad H body and comes with the original box and all the accessories, including battery and charger.
Iím the original owner.
The back has a total of 5295 activations.
One benefit with the Aptus is that you donít need to wake-up the back before capturing, as you would have to with the Phase P25+ and the P45+ when using them on a technical camera.
The back can capture around 70-76 frames per minute.
The Aptus 54S uses the Dalsa 22Mpix chip = very beautiful color gradation.
I believe this is the same back still being sold by Leaf, but with a new name:http://www.leaf-photography.com/products_aptus25.asp
Can be used with Leaf Capture 11 or Phase C1 Pro 6.3, as well as Adobe software.
