Another MP35 test
It's no big secret, that I am a huge fan of the Canon Macrophoto 35mm f/3.5 lens, so in lack of anything better to do, I decided to put it up for another test.This time it is up against a microscope objective, a Mitutoyo M Plan Apo 5X/0.14.
Now, this test is not exactly scientific, as I had to change the setting in between the two shots. The bellows is sitting a little lower than the camera on the focusing rail so I had to adjust, thus the lighting and the angle is not 100% the same in the two pictures. Furthermore there are 61 frames in the Mitu stack, and only 46 in the Canon stack!
The test is done at 2.5 times magnification, which is just about as low as you can go with the MP35 on a bellows at shortest extension, and the Mitu is mounted on a 100mm short tele acting as a tube lens.
A thing to consider is the effective aperture in which these lenses are operating.
The MP35, shot at nominal f/4, is an effective f/14 and the Mitu/100mm combo is around f/9-f/10. This gives the Mitu the edge regarding resolution. This was also noticeable when I changed the setting between the two sets, as the flash units has to be moved a little away for the Mitu shot.
Now, it seems to me, that these are both great lenses and really, this test might seem a little redundant, as they are used in quite different ways. The Mitu is an infinite microscope objective requiring a tube lens to work, and the MP35 is a "normal" macro lens working on its own, albeit a dedicated bellows lens.
Most people use the microscope objectives strictly for studio work, and that is my intention too, but I thought it would be interesting to see if the MP35 would hold up to this challenge.
On the other hand, the MP35 will be my go to lens for field work in the +2x magnification range in the coming season.
Anyway I think it's safe to say, by looking at these 100% crops, that both lenses are performing well, and more significantly, that the MP35 is a brilliant lens to take out in the field, knowing that it's hard to beat even with a Mitutoyo, which is widely regarded as a top performer. Of course the Mitu is resolving a little more detail, but in practical use, if one is not pixel peeping, the MP35 will be great!
