Re: Scales thread

Hello Macrero,

Yes of course, everyone takes photos with what they have or what they like :-)

But you have an Oly 50x/0.80, don't you?
This can also be pushed down with tube lenses with a small focal length.
And it has the same WD by 1mm.

Re: Focus bracketing and depth of field

Hello Igor,
Yes, the depth of field depends on the NA of the (microscope) lens and not on the tube lens.

Re: Scales thread

Hello Macrero,
Very nice photo!
But the resolution of your previous photos without the glued-in cover glass was much higher.

Re: Remedy for vibrations

I learned long ago that elimination of translation movements during stacking gives a sharper result, so I now turn off all corrections. Key to being able to do this is to ensure no movements. Capturing during a fast flash can help individual images, but if image to image movement is large, translat...

Re: small black point on the wall

Hello Chris, hello Rik,
I had feared something similar.
So far I've only found one.
So I'll have to start looking :-)

small black point on the wall

Hello everyone,
Today I noticed a small black dot moving on the white wall.
It is about 2mm long and in 5x looks like this:

What could it be?

Re: Best Canon mirrorless body

Adalbert, do they make image acquisition software like the EOS Utility for Fujifilm? On my Linux machine, I use Entangle. If not, that would be a deal breaker for me. I've exclusively use a Canon 50D (since it was released) and most recently the 90D. I would say 80% of the time with my microscopes ...

Re: Remedy for vibrations

Hello everyone, A very interesting discussion. As Kurt has already mentioned, using very short exposure times can be the solution. My setup is ultralight, yet I can take pictures with high NAs by using 4 YN660 flashes set to 1/128 power and remote triggering, synchronised via RF605C https://www.face...

Re: some scales

Hello everyone, And an animation for those who don't like Sketchfab :-) https://live.staticflickr.com/65535/53669572035_550809479c_o.gif Here you can clearly see that the wing is curved. The only question is whether there is a vein at this point, and this is not visible in the 3D model because it is...

Re: Best Canon mirrorless body

Hello ,
I would also like to upgrade and currently use the Canon M6 Mark II (almost the same as the 90D)
and for me only the Fujifilm X-H2 or X-T5 would be an option.
BTW, I take photos almost exclusively with the microscope lenses so APSC is ideal for me.
