Lou gave me an idea last night so just for fun I swapped the Xenon for my Lomo 3.7x 0,11 on the Makro-Symmar
Can you guess the IDs with these 100% crops?
Which is which?
Lomo 3,7 0.11 + Makro-Symmar 120 at 3.7x
Mitutoyo M Plan 5x + Sigma 150 OS pushed down to 3.75x.

Interesting!
My guess is that the first one is the Mitutoyo because the CA colours on the first one looks like the CA I see with my Mitutoyo.
I do not have a waffer so I can not test it my self, but my experience is that the Canon mp 35 mm macro works quite well in combination with some tube lenses - so if possible it would be interesting to se a comparrison.

Yes, I think the DCR-250 + $17 4x might work pretty well together.elimoss wrote:Wow! Good work! Care to try the Lomo on the Raynox DCR-250 or 150? Or even the 4x $17 dollar generic knurled objective on the DCR-250? Because those are inexpensive combos.
The stacking combos are hit or miss sometimes. You can take two good objectives and the aberrations don't cancel, they magnify these together.

I did try a MP-20 and it was not very good but I think I was pushing too much magnification, something like 6x, but I am sure there is a good tube lens out there somewhere that would work well for both MPs.
Let me know if you experiment on the MP-35.

This test reminded me of other work by a Member................

BRI have just visually tested all my microscope objectives in front of an achromatic 120mm focal length and I do not have vignetage with any. I see spherical aberration in the 4x, but that lens is the one that worries me the least, because it works perfect with the zoom.

Usually I have found no gain using a finite objective outside its specifications. The exceptions I use from time to time is a Nikon plan apo 20x 0.75 0.17 160 mm and a Nikon plan apo 10x 0.45 0.17 160mm that both works at 210 mm.
With a 20mp FF camera the Canon mp 35 mm seems to work quite well for example with the ITL 200. For ease of use the mp35 objective is better on a bellow, but my testing skills is not so good that I can decide if the image quality is better or worse when I use it with a tube lens.

So the answer is that the first crop, the cooler toned image is from the Mitutoyo. The second and warmer toned image is the Lomo 3,7 + Makro-Symmar 120.
I have some more examples of the Lomo+MS tube lens from some recent testing, the results are even better than I thought at first, I will post these in a couple of days when I get a chance.
Thanks for the all of the comments.
