Today we have “superbuttle”. Two top macrolenses of the most demanded focal length 100mm have a battle. The first one is Canon, and the other is Nikon. I didn’t see so far a big difference of these two wonderful macrolenses.
- Equipment for tests
- F2.8 diaphragm
- Canon 5D mark II
- Canon EF 100/2.8L IS USM Macro
- Nikon D800
- Nikon AF-S Micro Nikkor 105/2.8G ED
- Macroshooting by Canon EF 100/2.8L IS USM Macro and Nikon AF-S Micro Nikkor 105/2.8G ED
Today we have two tasks:
1) whether will give us a gain in resolution of a picture the installation of “super-sharp” Nikon optics on the Canon?
2) whether will give us an essential gain in resolution of a picture shooting on 36 Mpiks of Nikon D800 with “super-sharp” Nikon optics?
How behave Canon EF 100/2.8L IS USM Macro and Nikon AF-S Micro Nikkor 105/2.8G ED at a big distance we have already checked .
Equipment for the tests
In the article Canon 5D II vs Nikon D800 I came to a conclusion that it is better than Nikon at close distances therefore today I chose a distance in 3 meters.
Light — from the studio Broncolor Grafit generator, with a short impulse of flash which allows not to worry about possible greasing of a picture because of camera fluctuations.
Focusing was carried out in the LiveView 10x mode of both cameras, from a tripod.
Picture parameters: iso 100, 1/125, F2.8.
Diaphragm the main for the F2.8 test, the most open for both lenses to make the test for them the most difficult.
I will begin with installation of the lens Nikon AF-S Micro Nikkor 105/2.8G ED on Canon 5D mark II. It seems to be easy. Just take Nikon-Canon adapter and use it. But everything is not so simple. On the lens Nikon AF-S Micro Nikkor 105/2.8G ED there is a jumping diaphragm which at removal of a lens from the camera closes the “hole”.
Focus which takes place with the lenses Canon when we remove a lens from the camera and the diaphragm remains on that value on which we clamped the button — it doesn’t work. This communication with a diaphragm is purely mechanical. You just remove a lens from Nikon D800 — and the diaphragm is closed. It was necessary to solve a problem by mechanical way — to thrust an elastic band inside it. Everything was so simply.
Citizens! What is happening?!? Canon is sharper than Nikon? And how after that to tell about nano coverings and low-dispersive lenses of the lenses Nikon?
“The modest slogger” Canon EF 100/2.8L IS USM was sharper, than Nikon AF-S Micro Nikkor 105/2.8G ED.
Not to rely on the sight, I used the program test Imatest complex according to this table. As a result I got the maximum resolution in a picture with Nikon AF-S Micro Nikkor 105/2.8G ED@f2.8 — 43.9 lp/mm, and with Canon EF 100/2.8L IS USM — 52.3 lp/mm.
So eyes didn’t deceive us.

Look attentively at lines, there where they meet with big density. For example, to the right of the central square. You will see that lines can be divided visually on separate only of figure 10 into Nikon D800 and only from figure 8 on Canon 5D mark II (there where is 10 — lines stand more densely. If I removed in the correct scale, it would be 100 lp/mm, but the table is printed out in other format.). The sameit is observed on the meeting of vertical lines from above. I.e. the advantage on permission of Nikon D800 is, but it is insignificant in these sheaves camera+lens.
Part on macroshooting
Macroshooting by the lenses Canon EF 100/2.8L IS USM Macro and Nikon AF-S Micro Nikkor 105/2.8G ED
Our testing of these lenses would be incomplete if we didn’t raise the macroshooting question, after all both lenses are intended for it.
So I shooted macro 1:1 on both lenses. The extent of object is 10 mm x 4 mm. If it is interesting for somebody — it is the fuel filter from Mitsubishi Pajero, it was soldered on production which does any trifle for space, under a microscope.
And here it is possible to look, what turns out in a real size during the shooting 1:1.
In case of shooting in scale 1:1 we face very small depth of sharpness. So small that sometimes it is impossible to shoot in such scale.
Thanks to such programs as Helicon Focus, Zerene Stacker and Adobe Photoshop, that we have a unique tool kit to work in the micro world.
You will see the review of professional versions of these programs soon.
For now here is an example of similar processing.
