I need a solution of elevated imagery in my large residence photography gigs. Thinking of getting a 7.5 meter mast, but it is NOT that stable and I cannot, will not, shall not, I swear I won't.....send up an Alpa TC + SK 28 XL + Credo 60 that high and watch it sway about. Never (Although I do have a cable release of 10 metres)
At the same time it feels pretty sour to present an elevated image from some compact with IQ from another world compared to the rest of the shots. I am seeing a possibility of using the small A7R coupled with a high resolution wide for this single shot in most assignments.
What I would like to have is a lens in the 15mm - 18mm range. The smaller and lighter the better due to elevated position and wind/swaying concerns. Obviously I would love it as sharp as possible with good contrast - especially maintain contrast and being flare resistant if the sun position is not favourable. The one factor that I am somewhat less concerned with in this case is distortion.
(Canon 17Tse is too expensive and too large/heavy.)
