These are a few very simple tests to find out how the Tokina AT-X Pro AF 28-70 f/2.6 (Version 1 with Angénieux Design) performs on a video camera like the Sony PXW-FS5. This is the Nikon mount version. I used the Novoflex adapter and the RJ Focal Reducer to attach the lens to the camera body.
Zooming in, throwing focus and zooming out again works pretty well. It seems like the Tokina is nearly parfocal. There's a little bit of lens breathing at shorter focal ranges (e.g. 28mm) but it improves when zooming in. At 70mm breathing is almost invisible.
Operating this lens feels very comfortable. The rings are big and turn silky smooth. The focus throw is quite short. To get from the closest focusing distance (0,7 metres) to infinity you have to turn the ring for approx. 1/4th of a full rotation (=90 degrees).
Conclusion: Very useful all-around lens for cinematic video journalism that sometimes surprises you with that analog 70's Angénieux character. Combined with a focal reducer the zoom range feels just right for the type of work I'm doing most of the time.
Take look at these videos I shot with this lens:
- vimeo.com/195638933 (These images feel very glitchy and distorted and were also shot with the Tokina)
- vimeo.com/196892914 (The Tokina produces some really nice lens flares)
