Diverting from the States! series(which I am rather tired of!), I
present you with an awesome picture....
Why, you ask? Because this magnificent oak tree was separated from my 50D by approximately 5 miles!
I will allow you some time to recover before I explain.
O.K., First I started with my 500mm Quantaray f/8 prime tele.
Then I added the 2x that came with the aforementioned lens.
I stacked a Vivitar 2x on. Then I duct-taped yet another 2x of dubious lineage on. That is correct, -3- 2x extenders. All different brands.
Time for some math.
500 x 2 = 1000
1000 x 2 =2000
4000mm is impressive. No?
But wait there is more.
My 50D has an effective 1.6x crop factor.
So...4000 x 1.6 = 6400
Did I mention it was a long black tunnel with very little light at the end?
Wide open this is a f/64.
Stopped down to the max we find a tiny speck of an aperture: f/256.
I love taking my photography to the outer edges of sanity!
