I received my Zeiss Loxia 2.4/85 lens, and I have been waiting for an ideal time to try it out. The weather in Seattle has been lousy of late, but one evening I was home, and it looked like there might be a great sunset.
I set up the Roundshot VR Drive with my Sony A7S, on my Really Right Stuff TVC-34L tripod with the TA-3 leveling base.
For this lens, the entrance pupil does not have to be determined. The Zeiss data sheet provides the entrance pupil position at 58.7 mm in front of the image plane, and this translates to 62mm on the Really Right Stuff MPR-CL nodal rail.
The Roundshot VR Drive was setup using visual mode; that is, you position the drive at the start position and select, and then you position the drive at the stop position and select. The VR Drive then calculates the number of shots based on the lens size, overlap, and the x and y angles of view. With the Zeiss Loxia 2.4/85 lens and angles of view of x=110° and y=34°, the VR Drive calculate 2 rows of 9 images. Also, I had the bracket set to 3 images per position giving a total of 54 images and a duration of 44 s.
This panorama could have easily be taken with my Really Right Stuff PG-01 Compact Pano-Gimbal head. However, once in position, the VR Drive can produce accurate and repeatable image sets.
All image stitching was done with Kolor Autopano Giga 4.2, and HDR processing was done with Nik (Google) HDR Efex Pro 2.
That evening sunset was mediocre, but I will let you judge.
