(the title having been stolen from a phrase tossed about the camera club for the simple composition of an insect sitting on a stem, not the most creative image but the lines are nice) Not long ago, I was fascinated to read about the newer nicotine-like insecticides that have made their way into our corn products. Many of the seeds are coated with it at the time of packaging and the substance becomes part of the systemic plant circulation, showing up in the corn kernels and even the pollen without the grower even knowing it. Bee keepers use a supplement of corn syrup during the winter, furthering the concern.
I haven't had much luck with my 180mm lens on the 5D body, it's been a hit and miss proposition with most of the images being tossed away. A few days ago, I put it on the tripod and checked the focus and it appears to be off some. I've ran across this once before: the image could appear to be in focus through the viewfinder but the image on the computer screen appears soft. What led me to think about this was my images on live view were so much better than through the viewfinder. Live view reads directly off the sensor rather than off the mirror, so it's an accurate focus method. Of course, the live view is often sharper because you don't get the mirror slap vibration, but in my case it sure looks like the combination of body & lens tolerance was off enough to matter. I've dialed in some micro-adjustment so we'll see how it works. This image was before the adjustment, it's just barely OK because I fired a volley of shots while slowly rocking forward. I believe I was pretty lucky in anyone's book, considering the shutter speed was 1/20th at 180mm. My favorite macro lens is the 105mm but the 180mm is better for bugs because of the working distance.
