I got mine in the mail, finally!
My eyes are far too useless to shoot wide open with the mirror, or at any apeture really
However using liveview + 3x Magnifying Loupe + 10x zoom to get focus bang on, and makes for some fantastic pics.
Using this method + tripod on a stationary target, especially so at higher apeture, and I'm bloody impressed with this lense!
Every other lense I've got looks like a bit of a mash together when viewed at 100% scale, however this still has amazing detail at that size.
I've also found even when shooting at 1/4000th with ML Zebras turned on, it was overexposing some areas of the picture at F1.4 even on an overcast day. Will definitely look into getting some ND filters at this size.
Looking forward to taking some pics tonight in low light and seeing how it goes.
