I didn't process it. Only cut out the crop lines.
The source code is available here.
The images were taken without preparation.
Canon's auto-white balance did a great job on its own,
the A6000's white balance was on auto, the NEX-3n's I set up the foam BB,
the sharpness is yes, blurred, probably from pressing the trigger with my finger.
There is no flash yet, so the shutter speeds are too long.
After shooting, I noticed that both Sonya's aperture was clamped down to 16 (maximum at MP-E).
And the m / w adapter "EF-Sony E" affected the choice of aperture.
Although, like, all the frames in A-mode fotkal.
I'm going to sell a small sonka, because I haven't used it for a long time.
I also have a Canon 5D and a Nikon D200 e... it will be necessary to take pictures of the eyes of the os for comparison.

Usually, I take such a macro on the 650D via a USB cord from the netbook.
There's also a bigger screen than Canon's monitor.
Today it was lazy to deploy the full "macro installation".
And I wanted to compare these sonka and canon in order to understand
how the number of megapixels on the matrix affects the magnification of the subject.
Just bought an autofocus adapter.
But I concluded that the difference between crop 1.6 at 18Mpx and crop 1.5 at 24Mpx is almost imperceptible.
Yes, and it is more convenient to shoot with a Canon without an extra adapter.
Rava if someone is interested, of course I can take a picture.
I don't remember exactly about the aperture, but
it seems that you can't open a hole at a 5x approximation of the MP - E more than 1:6.3.

Waabshche-the main thing is a practical component, so that you can just go and take a picture on the wall of a hay eater or a butterfly without any sleepers and rails

, although you still need to wait for pictures at smaller apertures, because really the aperture from 8 even starts to spoil the image.

And the middle picture was taken in the classic way via MBS

, I already made an adapter, I thought it would take pictures, but figs are there. And moreover, at macroforums, similar results are also obtained in people who write that a soap dish through an eyepiece is better than without with a matrix instead of an eyepiece. Although in the sovdep-manual it is suggested to take photos without an eyepiece. Probably, so that Soviet citizens suddenly don't take a secret photo through MBS))

Well, fso, ixpert gave the green light to the MPE project ))))
Waabshche-something MPE is quite a cool object in resolution, and if you switch it to 3X mode, it will be many times better than my design, then the only question is the price ))
Another thing is that for such a price it has a number of jokes, the main one is that there is no focus. These are only experts who have never shot with interchangeable lenses in their lives, and they can say that it is enough to "move" the camera, but in fact this method only steers up to 10 cm, and above that, focusing is preferable, especially if the shooting is carried out through the branches of a shrub or grass.
Well, the fact that this MPE does not hold a diffraction pattern of 8, in many reviews they write about it, which is generally surprising, since in many objects the diffraction pattern of 8 is the optimal comprmis between GRP and diffraction.
Also interesting are tests for the evenness of the field, you can take photos of a flat section of a millimeter or an ordinary notebook in a cell at the very least.

Actually, I also don't understand why Ixpert wrote his speech about autofocus, when macro shooting, he really misses, and manual focus is needed - when shooting at distances from 10-15 cm and further in cases when the camera is not convenient to bring to the object - through branches or grass. Yes, and it is much more convenient to take a position and adjust the remaining centimeters by focusing.

As for the MPE, from what I read, I already understood that the field there is even in all modes, but everyone scolds it for sharpness above 3X, they write that it is better with shifters, well, the aperture above 8 is soapy.
In general, this object is for a full frame, maybe because the resolution is not so high and there is no sense from it at a high pixel density.

Yes, the case is hard

Waabshe "rational thoughts" of this type are purely those that do not coincide with his fantasies-he makes assessments of his own megafotkam, he assigns himself "victories" in disputes, and at the same time talks about what he did not even hold in his hands))
Increasing the sharpness on a larger matrix is something from the series like the dependence of the GRIP on the size of the matrix, in fact, just the sharpness with a decrease in pixel density theoretically decreases(the softness of photos from DSLRs), and improving the image on a large matrix is associated with a number of factors, this is a different scale, and DD, and smaller noise, but the contours of different halftones will be sharper on a small matrix, it's easy for me to see this practically, and theoretically it's easy to understand, but ikspert just can't see this))
He would want to take up his net, instead of tryndezha on
