reviews
-
- Unpleasant vignetting in the 50-70mm region at F2.8
- Noticeably lower image quality at close focus distances
-
- 2.8% barrel distortion at 24mm, zero at 40mm, 1.3% pincushion at 70mm
- 1.8EV vignetting at 24mm f/2.8
- sharpest at f/5.6
- “busy” bokeh and foreground bokeh is not harmonious
- the Tamron AF SP 24-70mm f/2.8 Di USD VC is better value and you get IS

reviews
-
- great optically, ergonomically and mechanically BUT big, heavy and expensive
- much less distortion than the Canon EF 24-105mm f/4L IS USM lenses
- nice bokeh
- some focus breathing at 70mm
- mild CA at 24mm minimal at longer focal lengths
- Photozone.de:
- a bit of a nightmare for us here at photozone. We experienced centering defects in several tested samples and up to a degree where we almost considered it to be enough
