Actually it is same sensor as the H5 and H6 50c. However I have been shocked by the huge amount of dust that it attracts from my 503cx. The back came with a small pack of e-wipes which I immediately lost. So I have been just blowing air from one of those rocket things at it, but have just come back from a shoot to discover that the huge amount of dust pretty much renders the entire shoot unusable without hours of minute post processing with the spot removal brush.
Can anyone give some advice as to the best or safest way of dealing with this? E-wipes? Eclipse and Pec Pads? A static brush (if so which one)? Any other thoughts - other than just buying a fixed lens camera. What do others do?
