FS: Schneider V38 lenses
I am selling a few Schneider lenses in V38 mount. The optics of these lenses are also available in plastic mounts for enlargers, but the full-metal modular V38 barrels are far more versatile. V38 lenses can be reversed without additional accessories or adapters, the aperture ring can be locked to pr...

I am selling more things, new ads will be coming the next days.

Re: Re:
Hello, I was wondering... being that it's been some years since this post, if you've revisited the idea of a PDF version. It would not only be more economical and portable, but searching the tome would be a snap! :-) Thank you Dimitri Katsaros Hi Dimitri, nothing new on this front, although I have ...

Re: Lens recomendation for film reproduction
I would like to ask a question similar to the the topic of the thread opener. For myself I also use macro lenses dedicated to my Sony camera for digitizing slides what works really well. At my Foto-Club at the University of Stuttgart there are lots of younger people who like to shoot film and we ar...

I never used a Kaiser Plano, but it seems to be a kind of light box, and it comes in different sizes. Just to make sure, I am going ahead and ask the obvious: are you masking off the ...

Re: Lens recomendation for film reproduction
Actually it's the exact opposite: You want a lens to have a good contrast. It's when the lens has low contrast that you start to lose definition and tonal distinction - and when you compensate for that by raising the contrast you may lose details. Roberts images are great to determine the resolutio...

Re: Olympus U-UCD (and BH2-UCD) information
It seems that over the years it has become more and more difficult to find Olympus BH and BX literature on the web, except for two or three well-known archives (one of which seems not to carry BX material, but quite a fewof the BH items can be used on BX scopes). When I got and souped up my BX 50, I...

Re: Help! Macro rail minimum 1µm step size is too big.
[...]no flash because the flash would take too long to recharge.[...] I beg to disagree. I just reviewed a 600 Ws studio strobe that recycles in 0.9 s after flashing at full power. The amount of flash light needed for photomicrography is perhaps 1/10 to 1/100 of that, which means recycle lasts only...

Godox AD600 Pro studio strobe
I think Godox strobes and speedlights have been occasionally discussed on PM.net in the past. I just wrote a review of the AD600 Pro, not specifically centering on its use in close-up and macro (but this is how I use it most of the time). Some potentially interesting features are: it is a battery po...

[...] Any recommendations how to overcome or improve the stepping size welcome. :) You already received good advice in the preceding posts, so I will not repeat it here.

Re: Help! Macro rail minimum 1µm step size is too big.
I already have a Micromate attached to my Olympus BX61. I don't want to have to remove it every time I want to do macro, so I'd have to buy another - and it takes up soooo muuuuch space! I agree that the Micromate is both large and unnecessarily expensive. However, with a minimum DIY one can build ...

Re: Protist aquarium- how long should I run air pump
So I started a 3.5 gallon protist aquarium today, with aquarium heater, air pump (bubbler), LED light and pond water sample and some aquatic plants / pond soil. For those of you who have set up protist aquarium and determined the best condition for protists diversity, what settings do you use? Spec...
