Have the Tokina AT-X 12-28 F4 PRO Dx for Nikon

How many F-Stops would this lens have? Just wondering if it's a prime lens. When I put my 3300 in aperture priority and dial the f-stops, it goes from F22 down to F4. Is that correct?

It isn't a prime lens and I think the F stop range you mentioned is likely correct.
This is a zoom, as a prime would only have one set focal length. I hope this helps.

Thanks Bill, it does help. I was just wondering what x 12 28 F4 meant, Thanks

It is a 12mm-28mm focal length zoom that is F4 at it's widest aperture. It is a wide angle lens good for landscapes.

Bill, I love the lens as it shoots very sharp pics. I was reading an article about finding your cameras sweet spot and they recommended you count the number of F-stops for the lens and then find the middle of that group and it might be the sweet spot. I am fairly new to photography and decided I will learn focus as, I see it, a picture not focused is ready to trash. I want my pics to be sharp and crisp. Paul
