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...

Relay system and optical formulas

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...

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...

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...

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...
