No, they are not too sharp in my opinion, to me they are close to perfect. I have a couple of questions on how you achieved this level of sharpness. Since you shot them at 1/1000 does that mean you didn't use a flash. The reason I ask is my maximum sinc speed, in order to use a flash, is 1/200. Also, I have not tried using tubes yet. Where did you purchase your 72mm tubes and do you find they work better than not using them.
Walt - Maximum sync speed on my camera for one flash pulse is 1/200 as well. For the bee shot I used flash in High Speed Synch mode. Basically instead of one flash pulse the camera fires multiple bursts as the slit formed by the shutter curtains travels across the sensor.
I bought my Kenko tubes off eBay. Actually I got two sets of 68mm so I could have more tube length options. Some very good deals on eBay for the patient buyer. My two sets, very lightly used, cost less than a brand new set. Tubes are good for increasing magnification without degrading optical quality. Getting the hang of stabilizing your camera at higher magnifications is challenging. Now that I can do that, with sufficient ambient light, I find it easier to focus in on specific parts of the subject at high magnifications than say 1:1. I do find tube setups awkwardly balanced compared to the telescopic magnification zoom of the MP-E 65. This is overcome with proper hand placement, cupped under the lens.
