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 .
