Yeah thats what I thought and how I had it set but my camera does not like the lens at all. It is an older used lens so maybe too old IDK. I took cell photos of my camera with lens mounted and emailed camera store so hoping they'll get back to me soon. My camera just does not recognize the lens at all. It's a pain not having a camera store anywhere near us.
So here's my new 24mm 2.8 on my camera everything looks good and works great
Then when I put the Sigma 105mm macro on my camera I get this
Either absolutely nothing even screen light won't light up
Or this
Or this, If I depress the lens release on my camera and turn it slightly like I'm going to take lens off I get something but I can't adjust camera settings at all
Sigh going to send the lens back so no macro lens for me
