I have had few problems in this respect in the past, but just recently things have got MUCH worse. So far none of my Olympus cameras have suffered in this respect (they originated automated sensor cleaning, but the new 5-axis stabilisation system does mean that if you suffer in this way it is almost certainly a service return, which is not good news, though the stabilisation is fantastic). Both the NEX6 and GX7 have had major dirt-on-sensor-problems (as has the A77), and I’m far from convinced that I have solved those problems – test shots seem OK, but when I take real photos later, problems seem to come back. The HUGE blurred blob on all on the images I shot today with the GX7 were very bad news – it is quite blurred, and semi-transparent, but I can’t see anything on the lens, nor on the sensor, and it is not just a spotting job. If it had been on the A77 (or NEX with the adapter), I would have thought it was dirt on the mirror.
The rubble the builders have not yet removed means I can’t get the car out at present, so I was trying to travel light to do some work for the BCLM today, hence I used the GX7 … I got very wet walking back there and home, as I can’t use the car. Having to spend time repairing the images is not good news.
I really like the GX7, but I need to solve the problem of the large dark spot that currently appears on all my images – any advice on what to do about sensor cleaning (I have a very effective air blower for sensor), would be welcome – emil me at mikehessey at gmil dot com (sorry for giving the address this way, and mis-spelling of emil and vmil, which should of course have an ‘a’ in them, but it does reduce the likelihood of spam or worse).
