This lense was given to me by a good friend. My hands shake a lot due to Essential Tremors. This lense does not have IS which makes it harder to use without a tripod. Other than that I'm glad to have this lense!
Outstanding images with this in conjunction with my 300mmF2.8L. Frustrating that it does not work with the 100-400 F4.5L ll USM, while it did work with the original version of this lens, (although this was not consistent). I also own the 1.4x extender. Curious that it works with all of the above mentioned lenses.
