Lensrentals' Roger Cicala has beaten us to testing the Nikon D610 for oil and dust accumulation - concluding it's 'certainly no worse than other cameras.' Cicala has had an initial look at 25 D610s and a further look after the first ten of them came back from being rented-out, making him uniquely well-placed to comment on the phenomenon. While we covered it in our original review, we don't have access to the sample size that Cicala has, so couldn't be so certain.

His testing supports the (rather hindsight-based) theory that the D610 is as much about drawing a line under the D600's reputation, as offering a new model in its own right.

The combined dirt build-up on the sensors of ten D610s upon return from being rented-out.
