Well I took your advise and bought the XA. Seems like a great lens – I really haven’t tried it out in the real world yet. Paul at Macie called it “sweet”… He needed to do some slight adjustments for CA and lens shading, but nothing out of the ordinary.
I don’t know where the extra bottom end came from. All I can think is that something was not right with my out-of-box setup. I was disappointed that it wouldn’t go as low as my SDX, but that is no longer an issue.
New toy: I wanted a higher-rez monitor than my Pana TC-7 that has focus assist, so I got a Marshall 651ST-HDMI. Only 6.5 inches, and even smaller 16×9, but the highest resolution and stunning picture – 1024×768 at $1600, and only 1.3lbs. Wanted HDMI so I could also use on my 7D. Trick was to power the AJA HD-SDI to HDMI converter box and mount. Velcro’d a power plate from Nebtek w/Pana DV battery to the back of Anton Bauer receiver box that stretches around the back of cam battery, and it works great – cam balance is fine. But a BIG rig! Clear the decks, I’m coming through!
