Question for Tamron 150-600 users
in Discussion Forum January 30, 2015, 23:16

I have just purchased the Tamron 150-600. When using this lens on a tripod, do you turn the image stabilizer off? I seem to get better images when I do.

Back button focusing?
in Discussion Forum February 22, 2013, 23:40

Has anyone used "back button focusing" (sometimes called thumb focusing)? The camera is reset to switch focusing from the shutter to the AF-ON button on the back of the camera. I have heard from one published nature photographer that this has several advantages in nature photography. I had never heard of this before, and am not sure what the advantages might be, so I thought maybe someone on the forum could offer some insight. Thanks.
