I've known of the 2x digital teleconverter on my E-M1 since I got it, and actually programmed Fn2 to activate it, but I didn't actually take any kind of test shots till just now and I must say I am very impressed! 25mm f1.8 25mm f1.8 with 2x digital tc 45mm f1.8 45mm f1.8 with 2x digital tc Comparing the 25mm with dtc to the 45 without, though it may not be clear, the image of the 25mm is a little softer (if you pixel peep down to 1:1) but still looks amazing! These are also SOOC jpegs which I simply watermarked in LR. I ordered a refurb 75mm which I will get my hands on when I return home next weekend! I wonder what how it compares with 2x dtc to the new 40-150mm at the 150mm end... Anyone else making use of this feature?
