Dutchman's Breeches
by Wayne Jones
Finally got out to shoot the spring wildflowers! I shot this lying on the ground a few days ago. Just as I aligned the tripod, a screw on my glasses popped out, so I had to use one hand holding my spectacle lens so I could see the LCD. I was relieved to see I got it all in focus, since there was no lee-way aligning the focal plane, even at f/22 with the 150mm. lens on a full-frame body. (Luckily, I was less than 1/2 mi. from car, so I made it out of the woods with one-eye vision without falling off a ledge. :D )
Canon 5D Mk. II
Sigma 150 Macro
1/50 sec. @ f/22*; ISO 640
*Technical Note: Many people refuse to shoot at f/22 because of image degradation due to diffraction with small apertures. This negative effect decreases as focal length increases, however. After all, an aperture of f/22 is physically larger in longer lenses. With my Sigma 150 mm. Macro, images at f/16 are sharper than those shot at f/22, but you really need to be a pixel-peeper to notice that. (And f/22 with the 150 is still sharper than shooting at f/16 with most shorter lenses.) An in-focus shot at f/22 is still a lot sharper than an out-of-focus image shot at a larger aperture, so I don't hesitate to stop down when I really need the depth of field.

7 commentsLovely. I like everything about the image. The curved stem, the odd number bloom, the clean bg, the lighting and plenty sharp (even at F22).
PS I don't worry too much about diffraction blur which can be corrected with post processing sharpening. I sometimes shot at F32 with my macro lens and get pretty sharp images.

Wayne, I use always f/22 and some of the photos that I like more are shot with f/32.
Take care.
