[QUOTE="Paganman2, post: 428866, member: 37668"] Right then - I have had a go today with this i set the camera up on a cupboard by my open window, i set the lens to the zoom length i use 250mm then with manual focus selected and single point AF-S, i then selected LV and zoomed to max, i chose a Cell Mast on a hill about 2 miles away as it was very clear and had lots of contrast, i manually focused by eye till it was very clear and i could see the individual wires supporting the mast, then i selected the viewfinder view and without moving anything i looked through and pressed the shutter release halfway, i got the focus dot flickering with the front focus bracket, so i oped the micro focus adjustment and moved it one step in the positive direction, i did this in steps till i got a solid focus dot without brackets illuminating, i found that i had this solid dot over 3 steps + 9 + 10 and +11 so i selected +10. I did the same test but on a house about half a mile away same set up till i could see a window sharp and defined in LV, and with the same settings i got the same clear sharp dot with no brackets. I took a couple of pictures at the same time and they are nice and sharp and very clearly show all the details of the Cell Mast i chose for the test. Have i done this correct? P. [/QUOTE]
