What Users Don’t Like About This Lens

Some photographers feel that the autofocus is slow. Additionally, photographers have noticed that the 100-400mm occasionally has trouble focusing in low contrast shooting situations. One build element of this lens, the push/pull zoom system, seems to cause some problems as well. Over time, many photographers claim that the push/pull zoom mechanism wears out and “binds up.” Canon has noted that regular maintenance, lens servicing and proper lens care can prevent push/pull mechanism deterioration.

Also related to the push/pull feature of the 100-400 is the issue of dust. Many photographers have observed that the zoom feature allows dust to enter the body of the lens, over time creating image sharpness problems and damage to lens optics. Regular servicing and maintenance can also solve this problem.
