>>3465524>>3465526>>3465414So here are my results from my super ghetto setup cause I don't have a printer.
As seen in the picture, the green is where I have the auto focus locked. At 1.8 it is clearly back focusing by a good 0.5 - 0.8 inches. You can sort of see it in
>>3465515 if you look at the metal hole in her hoodie. Notice how it is the most in focus. Which would make sense if it was back-focusing about 0.5 ~ 0.8 inches.
Now as we continue to ramp up the aperture, you notice that the 36' mark does not actually get sharper but everything behind it does. At F8, there is about 2 inches where there would be acceptable sharpness.
I don't usually shoot above F4.5 with this lens. So I see now why a lot of my photos are out of focus because at F4.5, there is about an 1 1/4 inch difference from where I am actually focusing. So if I focus right on her eye, it is actually focusing about an inch behind her eye thus causing oof images. Even worse at 1.8.
So I guess now my options are to either order Tamron's stupid TAP IN hardware to adjust it myself, or see if there is a local shop that happens to have it and have them do it.
I will do another for my camera's actual focus point to see where exactly it picks up focus relative to the rectangle point.
