Yes I guess I need to be specific and I think people tend to read into a comment, shooting a camera for 20 mins will not write anything in stone. This loaner is at factory and we all seen the back focus of the camera in the first images of the muskrat, I'm not understanding where everyone is thinking I said this loaner is the greatest thing since sliced beard.
It's completely unknown to me ?? I shot at 30 to 60 feet and it back focused gschlact picked up on that right off the bat !!
I shot it yesterday at 4 to 8 feet shooting birds and it's putting the same birds at the far back of the focus at close distance. All this is happening at the long end of the lens. So if some one can tell me how to get a lens to put focus 6 inches forward at 30 feet and an inch and a half at back at 6 feet at the same 400mm I'm all ear's,
I'm not talking about 100mm and 400mm I'm talking distance to target changes not mm to target ??
If it was front focusing at 100mm and back at 400 mm then I believe we all know what to do.
You do realize as the subject fills less of the frame at greater distance it is very easy for a AF point to be touching something else of greater contrast. Shooting a very small subject in a frame makes it easy for the AF point to cover an area larger than you think.
