4. Image resolution

Firstly, it’s worth to emphasize that among the lenses tested on Canon 20D, the records of image resolution belong to Tamron 2.8/90 Macro and Sigma 2.8/100 mm. Both these lenses found themselves in the region of the level of 44 lpmm or even slightly exceed it. After such beginnings everyone will have known what comes next, and the graph below dispels all doubts.

At the center of the frame Canon 2.8/60 Macro, even at the maximum aperture, reaches 40 lpmm, thus giving images of a very high quality. It’s still nothing compared to results it records at f/4.0-5.6, where we reach around 45-46 lpmm region. The formal record of 46.0 +\- 0.5 lpmm value is measured at f/4.0. So it’s stunningly sharp.

In similar superlatives we can talk about the edge of the frame performance. Many lenses don’t record such results even at the center. Canon, at the maximum aperture, exceeds 35 lpmm level, and for shaper apertures reaches almost 40 lpmm. Again, well done!

At the end we present clippings of our test chart obtained at f/2.8 and f/4.0 apertures.
