Michelle - how much light do you have on your test chart? It should say how many EV's you have during testing. More EV's will make your resolution #'s better. Could be that you need more light. Also be sure to save the test results and look through them. I noticed on one of my test charts that I was having a glare issue, and it affected results. I had to change to a matte paper instead of luster and re-run the tests to make sure the results were correct.
My 50/1.4 had numbers in the 900-1000 range with ~9.5 EV light, and better than that once I moved my setup where I had closer to ~12-13 EV's based on natural light.
on the last test it said my EV ranged from 6.8 - 7, so I guess i will have to move rooms as that is as much light as i can get in the room where my computer is set up.. I printed the charts just on plain white paper, but have another blank white piece of paper underneath it so that the white is bright, they are only on A4 size though - is that big enough? On the tests the green tick came up so I thought they would be ok and on the multifocus I did have to move the chart closer than the other chart for it all to be on the frame, but got the green tick so thought it was ok... maybe that one needs to be printed bigger? going to be a big effort but I will move everything to a different room tomorrow, retry and tests the 100mm too. Thanks for all the help so far! really appreciate it!
