Tamron SP 15-30mm f/2.8 Di VC USD


Image Stabilization on Tripod Destroys Sharpness (Nikon D810, Dark Rocks)

This f 2.8, 4, 5.6, 8, 13 aperture series runs from 4 seconds to 81 seconds and shows the damage to image sharpness caused by the image stabilization function (“VC”) of the Tamron SP 15-30mm f/2.8 Di VC USD.

See also the Canon 200mm f/2L IS example. Image stabilization needs special attention for tripod shooters and indeed is not always a win, even handheld.

Being a low light, theatre Photographer by trade, I NEVER use a tripod with the I.S. switched on.

I remember when I first started using I.S. lenses, it took me about 3 performances to figure out that it was impeding image sharpness. The sad thing is, the local Canon rep had NO idea what was going on.

Good information for any of us starting out new with I.S. lenses …
