Dmitri from megasetphotography.com shares a great tip to help you pull focus and zooming on your DSLR camera while shooting video!
In the video, Dmitri goes into detail about his experience with the Tamron SP 24-70mm f/2.8 DI VC USD lens and at about the 4:00 minute mark in the video he shares the problems he had with pulling focus and zooming with Tamron’s reversed zoom/ focus wheels.
Typically, on most brands of lenses, the focus wheel is positioned towards the front of the lens with the zoom just slightly behind that. Tamron’s wheels are reversed on the SP 24-70mm, with the focus wheel positioned closer to the camera and the zoom towards the front of the lens.
Fortunately, Dmitri has found a ‘quick fix’ for pulling better focus and zooming by simply adding a LCD Viewfinder (for an extra point of contact) and re-positioning your hands on the camera, from the traditional way, to a new way that allows you to pull focus while zooming!
Position your right hand on the barrel of the camera with your thumb and first finger gripping the lens. Then place your middle finger on the focus wheel of the Tamron lens and that’s your focus puller! Zoom with your left hand as usual, and pull focus with your right hand middle finger.
Dmitri claims that with a little practice, you’ll be able to accomplish fast, smooth rack focus/zooms! This trick may not work for every lens setup. But on lenses like the Tamron SP 24-70mm f/2.8 DI VC USD, it seems to be a useful tip!
I came across this video while doing research, because I’m looking into purchasing this lens for myself. I’ll keep you posted if I end up purchasing it myself.
Here’s some of the gear mentioned in this artical:
