I have to say at the out set I don't like using 3rd party lenses with my Nikon cameras even though I have the tamron 90mm macro lens.The reason being that the lens coatings may not be ideal for the Nikon sensor and throw the colours out. I may be wrong its just how i think. To me far better to manufacture match camera and lens.
Ok now for your problem Pete with the CF card. options, first format it in a card reader then in camera. This will ensure you are formatting an independant formatted card which might clear any card corruption? Second is to try another CF card. Third remove all cards format the camera. .
At least then everything should be back to manufactures spec. I actually had a couple of minor problems with my D810 and reset it a couple of times now it is ok, sorry can't remember exactly what they were now, but something to do with the camera settings wern't showing correctly
Ok now for the latest upgrade, I have had no problems with it but the lenses are nikon as I have said.
here is the info on latest firmware updatec to version C 1.13 and L to 2.017
- • Added the following supports for AF-P lenses:
- - If the standby timer expires after focusing, the focus position will no longer change when the timer is reactivated.
- - When focus is adjusted by rotating the lens focus ring, the focus indicator in the viewfinder (and in live view, the focus point in the monitor) now flash to indicate when infinity or the minimum focus distance is reached.
- • Fixed the following issues:
- - Microphone sensitivity would sometimes not be correctly adjusted when movies were recorded with Auto sensitivity selected for Microphone sensitivity.
- - The camera would sometimes stop responding during multiple exposure shooting.
So according to that it should not affect your sigma lens.
Doing the upgrade the bit I missed the "bin" part have highlighted and wondered why i could not complete the firmware update. Should have read it properly. also note para 4
