Great article, thanks very much. However, I\'m a bit confused by your statement above that you\'ve giving up a bit of resolution: it seems from your test that although there was some additional astigmatism and distortion, the MTFs were higher with the SpeedBooster compared to the 5DmkII across the board? Or am I missing something?
I wrote that yesterday while I was still crunching the numbers. I think I wasn\'t mentally ready to accept those results, maybe
At that time I was looking at the astigmatism and the lower numbers (where astigmatism was having it\'s effect) do show a slight reduction, but the average at each location (sagittal and tangential) are improved.
