I had left the view finder open, it asks you to close it during a test, so think this may have affected the test. I ran the test a second time on the 500 & 1.4 combo and it got half way through and said that something was wrong and could not get an accurate reading. It gave me a MA for the straight 500mm of -6 ! Big difference to my original -1 but I would have done that original MA test at 25 times focal length so around 12.5 meters. I will run the test again once I can wok out what it was talking about.

IT did shoot at a low shutter speed 1/200 and was using 200iso when the iso was set to auto - I did get a dialogue box telling me that iso 200 was not optimal and I was in a mode that I had not heard of before. I just stood there watching the screen and waited for it to finish. It took some 40 images and plotted them visually on a curve. I then closed this part of the program and pressed the start on the test. The target finder was easy to use and it gave me a green tick when it was happy with alignment. I had my laptop sitting on a bin next to the tripod so could easily use it. This is all the room I had and is about the average for distance to bird for me.

The target was taped to a wall outside and I set up at 19.2 meters. I had my 500mm with 1D MK4 set at -1 MA and the 500mm, 1.4ext and 1D MK4 set at -2 MA using methods above. I have not been that great at taking the images manually and checking them making little adjustments taking more images and so on. The fact that the computer/software takes over and analyses the images was a real winner for me. To date I have tried the original cardboard box at an angle with target trick and have even given Roger Clark's method of using live view a go. Cost me $108 AUS and was loaded onto my computer within ten minutes. After reading good reviews on the various links.

After seeing this thread I bought it to try it out.
