Before launching into our comparisons, let’s take a little closer look at how the two versions of the Tamron lens perform:
Tamron SP AF 90mm F/2.8 Di MACRO mounted on a Canon EOS 1Ds Mark III and on a Nikon D3X:
With a DxOMark overall score of 23 for the Canon mount and 22 for the Nikon, the two 90mm Macros are for all intents and purposes identical.
Strong points:
- Excellent sharpness.
- No distorsion.
- Attractive price.
- Very reasonable weight.
Weak points:
- Vignetting, with a loss of 1EV in the last 1/3 of the field at f/2.8.
- Noticeable chromatic aberrations in the corners.
What might be the best 100mm macros for Canon cameras?
DxO Mark Score:
And the winners are …
- 1st place at 28: Carl Zeiss Makro-Planar T 100mm f/2 ZE Canon.
- 2nd place at 25: Canon EF 100mm f/2.8L Macro IS USM.
- 3rd place at 23 (tie): Tamron SP AF 90mm F/2.8 Di MACRO Canon and Sigma 105mm F2.8 EX DG Macro Canon.
- 4th place at 18: Canon EF 100mm f/2.8 Macro USM.
Of note for those with a limited budget, Sigma and Tamron offer very satisfactory alternatives in terms of image quality… and which are nearly 2 times less expensive than the L series.
Also note that the Canon EF 100mm f/2.8 Macro USM is a bit dated: there is a 10-year gap between the first and fourth versions.
Comparison: Tamron SP AF 90mm F/2.8 Di MACRO Canon vs Sigma 105mm F2.8 EX DG Macro Canon vs Canon EF 100mm f/2.8 Macro USM on a Canon EOS 1Ds Mark II
Comparison: Tamron SP AF 90mm F/2.8 Di MACRO Canon vs Canon EF 100mm f/2.8L Macro IS USM vs Carl Zeiss Makro-Planar T 100mm f/2 ZE Canon on a Canon EOS 1Ds Mark III
The most and least sharp:
- The most, at 59 lp/mm: Carl Zeiss Makro-Planar T 100mm f/2 ZE Canon
- The least, at 57 lp/mm (3-way tie!):
- Canon EF 100mm f/2.8L Macro IS USM
- Tamron SP AF 90mm F/2.8 Di MACRO Canon
- Canon EF 100mm f/2.8 Macro USM
Note: The difference between the Zeiss and the other cameras is very small, and in fact all the lenses have excellent sharpness.
The most and the least bright:
- The most, at 2.2 T-stop: Carl Zeiss Makro-Planar T 100mm f/2 ZE Canon
- The least, at 3.4 T-stop: Canon EF 100mm f/2.8 Macro USM
Note: The difference of 1.25 EV can be important under low-light conditions.
The most and least amount of vignetting (again, “the most” is not good here):
- The most, at -1.5EV (2-way tie!): Carl Zeiss Makro-Planar T 100mm f/2 ZE Canon and Canon EF 100mm f/2.8L Macro IS USM
- The least, at -0.9EV: Sigma 105mm F2.8 EX DG Macro Canon
Note: Vignetting equal to or greater than -1.5EV is significant and noticeable.
The most and fewest chomatic aberrations (again, “the most” is not good here):
- The most, at 11µm: Canon EF 100mm f/2.8L Macro IS USM
- The fewest, at 3µm: Carl Zeiss Makro-Planar T 100mm f/2 ZE Canon
Note: A LCA score of 3µm means that the aberrations are so insignificant that no post-production editing is required. But at 11µm, LCA is starting to get serious, which means a significant increase in post-processing time.
What might be the best macro lens for Nikon cameras?
DxO Mark Score:
And the winners are ….
- 1st place at 34: Nikkor AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED
- 2nd place at 29: Carl Zeiss Makro-Planar T 100mm f/2 ZF2 Nikon
- 3rd place at 22: Tamron SP AF 90mm F/2.8 Di MACRO Nikon
- 4th place at 21: Sigma 105mm F2.8 EX DG Macro Nikon
Comparison: Tamron SP AF 90mm F/2.8 Di MACRO Nikon vs Sigma 105mm F2.8 EX DG Macro Nikon vs Carl Zeiss Makro-Planar T 100mm f/2 ZF2 Nikon on a Nikon D3X
The rankings here are a bit less close, with both Nikon and Carl Zeiss providing an exceptional lens for Nikon mounts.
