>>3242585Well, it seems the problem is the lens itself, rather the size of the extension tube. I made a snoot light and was able to get 1-5 second exposures without a problem. I focus peeked with the LCD screen and turns out these two images are the best it gets in the DOF with clarity. This image was a much smaller fly with eyes much smaller than those in the post I'm replying to. I didn't focus stack this image. The DOF is closer to the front of the eye along with some of those hairs on the left. I think I've gone past the limit of the lens.
