Hi Nancy, please post a couple of those shots so that we can SEE what the problem is and possibly identify it's cause.

Which lens specifically? The EF 100-300 f/4.5-5.6 USM does not have IS. The EF 75-300 f/4-5.6 IS USM does, but it is an early version that should be turned off when using a tripod. The IS in this model will act erratically when there is no motion to correct. The latest versions, EF 70-300 f/4-5.6 IS USM and EF 70-300 f/4.5-5.6 DO IS USM, can be used on a tripod with IS turned on.

Hey Jon - I just wanted to interject a word of thanks to you for always answering these type questions intelligently. I don’t know how you always seem to have the facts on this type of thing, but I always learn something from reading your answers. Do you own/work in a good camera shop? You certainly know your tech stuff! Irene

Thanks. No, camera shop. I'm just a gear-head who's picked up a lot over the years, especially with respect to the Canon system I use.

EF 100-400 f/4.5-5.6L IS USM is a pretty good lens. You should be getting sharp photos from it. However, like the EF 75-300 IS mentioned earlier, the 100-400L has an early version of IS that needs to be turned off when used on a tripod. Left on it will create blur because it will function erratically if there is no movement. Other possible causes of blurriness when shooting from a tripod: (a) UV filter. Take it of and simply use the hood to protect the front element. (b) misfocus. (c) pressing the shutter button directly. The camera will still have some shake. When shooting from a tripod, a remote release is necessary.

Hi Nancy, I also have the 100-400mm and it is my favorite lens. I need to get a stronger ball head for use on my tripod (which I turn IS off when using) but I leave it on and get great results with my monopod and handholding. I found my lens really likes the f/7.1 - f/11 range very much although it goes to f/40, I rarely use that much DOF with this lens. I do not use any filters (just the hood to protect it) but will occaisionally use a circular polarizer since I have a 77mm that fits it. Also note the 2 modes of IS 1=vertical & 2=panning. I rarely even try panning since I dont have one of those $590 Wimberly heads http://www.bhphotovideo.com/c/product/404536-REG/Wimberley_WH200_Gimbal_Type_Tripod_Head.html which I hope to get one day...
