The performance of the Canon EF 28-70mm f/2.8 USM L came as a surprise because its optical quality exceeded the EF 24-70mm f/2.8 USM L (two samples tested). The lens doesn’t really show any significant flaws – the resolution figures are very high and distortions and especially vignetting are very low. The degree of CAs is pretty decent for a zoom in this range. The build quality is very good with only the reverse zoom extension as a minor downside. However, similar to its successor the zoom range is not all that attractive on APS-C DSLRs (45-112mm). For most it’ll make more sense to have a deeper look at the 17-40mm f/4L when looking for a high quality standard zoom. While not tested in this scope it is probably a valid assumption that the EF 28-70mm f/2.8 USM L will surely find many happy full frame users becuase it simply remains a great lens! READ FULL REVIEW
