What Buyers Say
Canon L EF 600mm f/4L IS III USM 600mm
The Canon RF 600mm f/4 L IS USM lens is widely praised for its exceptional sharpness, fast autofocus, and significant weight reduction compared to previous versions, making it a favorite among wildlife and bird photographers. However, a notable number of users report a serious image stabilization issue causing vertical blur at slower shutter speeds, particularly with the 5D Mark IV, which has led to frustration and some negative reviews. Other complaints include the flimsy included case, expensive replacement hood, and a few isolated quality control problems like stripped tripod foot screws and a failed front element coating.
