I got my camera back one day before I left to go to Tuscany on holiday, this was after having to send it back after the recall service when it came back with the sensor filthy. I've had major issues with my 1Dx since I noticed the oil splatter on it last September, about a month after I got it. Its been to Canon twice since then, and back twice again, once for the recall and again to clean the sensor. On first occasion sensor came back much cleaner but not perfect, 2nd occasion same thing, 3rd occasion (recall) sensor came back filthy, 4th occasion it was spotless.
Anyway thats a brief history of it, so for the first week or so in Tuscany I have used it largely for street images, shots of my kids in the Pool (12fps), the odd landscape but mostly all at the F1.2 - F5.6 aperture range using roughly 3 lenses, 85mm, 24-105 and 70-200. So on Monday past I see some mist forming in the Hills we are in and jump in the car to go to higher ground, and for all of my landscape shots I am using my 70-200, possibly the 24-105 to begin with, then switching but only one lens change. So now I am shooting at F16 and occasionally at F22. Get back to the Villa and dump the images into Lightroom and start to process them and to my horror there they are again, what looks like oil splatters. I can be pretty certain its not dust as all of the marks are the same size size, similar density and one clone/heal brush size in Lightroom fixes them all. There are bout 20 of them, on a portrait orientation image with the bright sky in the upper 1/3rd that is where the majority are showing themselves, in the lower 2/3rds where the landscape is its more difficult to highlight them. I'd need to take an F22 image of a bright sky to be able to pick them all out.
Do Canon have an issue with this camera which is not being highlighted by their main sector of users, sports/news photographers who are probably shooting at F2.8-F5.6 for most of their work and at these apertures the marks which will appear larger but are barely visible if at all at that range?
I'm seriously unhappy about the 1Dx, I've owned 4 different DSLR's prior to this and never had a sensor dust/dirt issue and I certainly did not expect it from this body having shelled out more than the total cost of the previous 4 on this one body. If its acceptable to the moderator I'm going to post this under a new thread too as a general question to get other user experiences.
