I'm having a senior moment here and need a formula. I want to take a mirror image of a church steeple using 24x48 piece of black acrylic as the mirror...let's assume that the steeple is 200 ft tall. How far from the steeple do I place the mirror to fill that mirror with the steeple...like I said, just need the distance/size relationship formula. Thanks
Geez, does no one here rely as heavily on Canon's own MTF characteristics as I do? Just look at the charts to find those lenses with nice horizontal squiggly lines, not the ones that slope down, the straight ones.
It's not rocket science here...set your budget/requirements/wants, order it/chect it out/keep it or send it back, and repeat process. As someone else mentioned, don't try to get off going cheap...that doesn't work for ____!
