as far as IQ goes, but im also happy with my 80D and 18-135 so i dont NEED the best
I recently picked up a 80D. How to you find the image quality with the 18-135 compared to the 16-35L? I like the focal range of the 18-135. I haven't had time to really test this lens. The IQ on my 16-35 is outstanding. If the IQ of a the 18-135 will permit sharp 16x20 prints it would be a fantastic walk around lens on the 80D and I can keep the 16-35 on the 5D iii.
