Rik...I don't want to exaggerate with compliments, also because my English is very shaky, but your messages always dissolve the fog! Now for me is much more clear the general physiology of the relay system. Many thanks- My actual configuration is far from perfect, but you can have a good idea what I...

Hi Rik and thank you very much for your really precious contribute! Well, now my relay system is composed as indicated below: Front section: CCTV 4K lens 3.2mm f/2.0 1/1.7" Rear section: Schneider Xenoplan 28mm f/2.0 C-mount (inverted) http://www.photomacrography.net/forum/userpix/593_001_1.jpg The ...

Hi everyone, currently, I'm playing with a relay system to increase the image circle of a small CCTV primary lens until to cover a MFT (m4/3) sensor. This "old trick" allows to increase the depth of field thanks to the short focal lenght of the primary lens, whose primary image is magnified by the r...

Does anyone have a PDF scan of the original sales brochure for the Leica\Wild Heerbrugg M3Z stereo microscope? I'm looking for some information on what accessories and objectives were made for the M3Z. Hi atariwarrior, I have shared my detailed pdf (80 pages...) with you. Visit this GDrive link... ...

Looking forward to buy a Macro Nikkor 35/4.5 RMS screw, in good shape and optically perfect

Thank you very much, big Charles...the second solution is simply the "Columbus's egg"!!! Now I only have to find a good (fixed focal) C-mount 10-12mm, even better if supplied with a filter size of 28mm (that matches perfectly the Periplan 10x18 thread). I hope that this "overpopulation" of lenses (e...

Dear friends, I'd like to use a Microscope Camera Optikam B5 (C-mount, 5 MPixel) on an "evergreen" Leitz black enamel finished trinocular microscope. The problem is that it's equipped with a quartet of "old but good" Leitz Apo Objectives (12.5x, 25x, 40x and 90x) that require a compensating eyepiece...

Ciao, I have the Canon 35mm f/2.8 and I think it is a very good lens, much much better than the more blazoned Luminar 40mm. It suffers a bit for flare and low contrast with very reflective subjects, but resolution its very very good. Many people don't like it simply because they use this lens at too...

Hello everyone, I have to renew my photomicrographic equipment. So, I would like to sell the following lenses: - Zeiss Plan-S 1.0x (NEVER USED), for Zeiss Discovery Stereomicroscope http://www.photomacrography.net/forum/userpix/593_plans_2.jpg - Nikon U20 0.33 (iris equipped and exra long work dista...

...But the Nikon U5 isn't as good as the Nikon U10. I had a Nikon U5 and for me, it's not advisable for photomicrographic use. For me...

Ciao Peter, I have the Nikon U10 and the Nikon U20; they are achromat iris-equipped metallurgical objectives. The Nikon U10 (that I use currently) is a very good choice for photomicrography at 6-8x; the Nikon U20 is a good choice but only with 200mm or more of tube lenght (if not, you have very bad ...

Hi everyone, I have just tried the formula suggested by Rik using a deeper tube lenght difference (56mm) and results was exciting! Olympus MPlan 1.3x 0.03 = Focal lenght calculated: 70mm Luminar 63mm f/4.5 = Focal lenght calculated: 64,5mm Canon 35mm f/2.8 Photomicro = Focal lenght calculated: 34,5m...
