Here's my lenses tested out on a, wait, this ruler is lame, it has no labels and it's the triangular engineer kind! Anyway, I'm pretty sure it's millimeters, so here we go. We'll go widest to longest in focal lengths, which when reversed, is quite fittingly the opposite, where a wide lens reversed gives you a higher magnification than a long lens reversed.
My findings: The 70-200 and the 35 were both surprisingly sharp when reversed, and the 35 especially has a great deal of magnification. The fisheye was beserk. Since it has the petal hood, it doesn't meet with the circle opening of the camera very well, and you'd think that with the light leaks everything would be overexposed? Not so. In fact I had to crank up the ISO and lower the shutter to get a proper one. The 17-40 was great too, I tested it at 17mm but it was so close I couldn't fit all of the 30 in the frame along with the lines. I couldn't do this for the fisheye either so I dragged the lines down to meet them, but other than that each photo is not cropped and untouched.
For what it's worth, reading my camera data for the fisheye shot, I got an aperture value of >f/1024.
After the horrible "drop" incident at Western Ave, B&H delivered a present in the form of a Nikon 18-300MM lens. Now, I should not have to switch lenses for the big tele shots. After unwrapping the lens I went trackside to nab #3 at Belmont. I hit both a long tele then stood back for this wide angle at high speed to test the limits. Not bad at all. Expensive mistake, but at least I received a new toy from the mess.
Love to see our students at David Vincent's Martial Arts perform after putting in the work for belt testing!
test realizado a eso de las 14.30 hrs. en la biblioteca de la universidad del pacífico...
existe realmente tal ancho de banda??
los tests siguientes arrojaron velocidades entre 3 y 5 Mbps... quizás fué "el minuto feliz"
It's always a good idea to run a test roll through a new camera. While I don't usually post those rolls I really liked this one.
