Re: Pushing down the PN105 and Scanner Nikkor to a FOV of 100mm

Hi Lou, just to support your vision I once showed how to use the Nikon 8000 Coolscan lens in telecentric mode in the post: https://www.photomacrography.net/forum/viewtopic.php?t=38761 The piece that I photographed, with a Fujifilm X-T1, APS-C sensor, was a piece of curved vessel colonized by worms a...

Re: WTB: Canon EFS 60mm or EF 100mm USM

If you're interested:

I have found a Canon EF-S 60 mm 2.8 USM Macro in a Mediamark from Spain, it is new, only with the damaged box.

The ebay number is 224386987658, the item has a 20% discount.

Re: Mitutoyo 2,5X QV Microscope Objective for macro

Hello, I work with an APSC camera (fujifilm x-T1) and I am very happy with my QV2.5x. It is not advisable for full frame (vignetting). It must be taken into account that it has an NA of 0.14, the same as the Plan Apo 5X, therefore, and if I am not mistaken, they have a similar resolution. Therefore,...

Steve,

It is an impressive set, and the 3D vision is spectacular. It allows us to visualize the morphology of these algae in a totally illustrative way. Congratulations.

Congratulations.=D>

Hello Chuong: Yes, it is very clear to me. It is also an impressive setup, and shows your improvements to achieve telecentricity with the Rayfact: an adjustable tube and a mechanical iris.

Hello: an impressive image!!.

Out of curiosity: how does the Nikon Coolscan 800 behave vs the Nikon Rayfact 95mm f2.8?

Could you show the setup to make the Rayfact telecentric?

For example at the moment ...
