jk i shoot in raw apeture priority am now using partial metering rather than matrix usually centre point focussing auto iso set to min 100 iso max 3200 iso with a minimum shutter speed of 1/1250th sec to cope with 500mm lens set up hand held . i have tried switching back to a non variable iso but that makes no difference . as i stated with previous nikons i have only had to compensate upwards by a couple of notches i.e under a full stop ,but it now seems that at least a full stop is needed or more .lack of suitable targets is the real problem at the moment .as raptors haven't yet moved back in any amount of quantity . all other settings are fine ,been through it all 3-4 times and as stated its not just me others coming up with the same results with similar lens set ups

Might be worthwhile having the camera checked. I know that is a pain but if you are a Nikon NPS member they usually turn these repairs around in less than a week.

i think they have changed something in the metering jonathon ,i have several contacts who have them and two close friends have the same camera and have followed me with the same lens's as well .we are all getting the same results .so unless its a batch issue problem its something in the metering system

Have you tried a zoom lens? Wonder if the effect varies with % sky. Presumably the TC isn't contributing?

early days yet eric ,tried both t.c's with no change ,not yet tried it with the bare 300mm ,i only have one other lens a wide angle ,as i travel light and the prime gives me all the variations i need .. as i said lack of target birds is not helping ,and depressing gray skies virtually since i bought the camera haven't helped either .i will have to try higher positive compensation 1.e a full stop or more till i come up with whats the right combo . the frustrating thing is at eye level ,birds at low level,macro /close up its fast and accurate to ,as soon as a large amount of sky comes into it it all goes out the window .i am presuming its the new sensor and lack of anti-aliasing thats changing things ,the only way to make sense of it is to say its performing more like a canon than a nikon metering wise just to put my own mind at rest i have just been back through exif data /historgrams on the two other cameras on b.i.f ,it seems that e.v ranged from 0 through 0.67 up to 1 full stop ,and seemed to have a fair bit of latitude in the actual raw files ,i think i,m starting to realise that theres not as much leeway in the 7100 it has to be virtually spot on or it shows up either as a exposure problem or noise .i will now try setting it at plus a full stop and see how that works once i can get some b.i.f that is .

May be something that needs raising up to Nikon for a flx via a firmware revision. The metering algorithms are very complex and take into account many different light situations. It sounds like there is a bug in the D7100 code. I can only recommend that you make a phone call to Nikon UK Tech Support. I have always found them very helpful but I have had NPS membership for many years and also I used to know the Nikon UK MD so maybe I was just lucky.
