I just bought a new 50 m compact macro lens and was testing it out.
Sorry in advanced, I didn't take the time to fix these pictures nor the time to set up a nice back ground. I used my mat cutter to hold the ruler in place, And double sided tape to hold the quarter to the ruler.
These were taken using a Canon Xt, 50 mm F/2.5 macro lens
first picture 1:10 2 ft.
next is 1:8 1.645 ft.
next is 1:6 1.333 ft.
next is 1:5 1.167 ft.
next is 1:4 1.038 ft.
next is 1:3 .887 ft
next is 1:2.5 .815 ft
And the last one 1:2 .749 ft
Any thoughts.
And again sorry for being so long, And thanks for looking.
