Re: Advice please: High NA air objective with small WD
Horst, Yes, this is still very much of interest to me. One thing I’d like to do is look into holes as you mentioned. For example, in my post on Papilio ulysses wing scales , I’m fairly sure the black spaces in the lattice work are not through-holes, but light-absorbing dimples or shallow pits. Even ...

Re: Looking for advice to improve sharpness
Mycobiont, Moving from images A through E, it appears that noise is increasing. Any idea why this is? Are you increasing your ISO? Or is your histogram moving toward the left? Plastic from most milk jugs, in my experience, is too close to transparent to be a good diffuser. To test it, try looking at...

Re: Can someone tell me the difference between these two Nikon apos?
Thanks! I don't suppose you can tell me the difference btween these three 20X plan apo objectives? (snip) https://www.ebay.com/itm/Nikon-20x-0-75-CFN-Plan-Apo-Microscope-Objective/224148776818 I can't speak to the other objectives listed, but this one is of the well-known N-Plan series, as pictured...

Re: Nikon Industrial Lens Website PDF
Thanks, Robert. Those are handy resources to have here.
Of course, seeing them cost me a wince-producing amount of time down the Rayfact rabbit hole. (And I don't need any more lenses right now! I don't, I dont. . . .)

Re: Mitutoyo 7,5x MPlanApo
(per Google translation): Hello, in Mitutoyo's MPlanApo series the 7.5x is much more expensive than the 5x or 10x (almost double). This model looks better than the others, is this difference worth choosing for our use? What is the difference? I wonder if it's worth reselling my 10x to invest in thi...

Re: Samsung NX1 e-shutter
Ben, I don't know the answer to your question, but since no one else has taken a shot, I'll share a few ideas, some of which you've likely already considered. First, I shoot high-magnification macro without electronic shutter, using continuous illumination. To keep shutter-induced vibration from sof...

Re: Canon Lenses usable on a Nikon Z Camera with new Fotodiox adapter
Robert, The other way around is possible of course but the market would be small since infinity focus is impossible. Agreed, such an adapter would only be compelling for use with the Canon MP-E 65 macro lens, where infinity focus is irrelevant. However, this particular lens is the only Canon lens th...

Re: Raynox dcr150 custom tube lens
leanderborg220, Enlarging on some above comments: The various ultra-black paints seem to have durability issues, and likely do a poor job at suppressing low-angled, glancing light--which can be a large and difficult-to-trace cause of flare with tubes and couplers in macro setups. Flocking every poss...

Re: 50X objective recommendation
BTW, what about the Mitutoyo M 50 / 0.65? https://www.photomacrography.net/forum/viewtopic.php?f=27&t=42479&hilit=Two+bargains The Mitutoyo M Plan 50x/0.65 objectives I've seen are optimized for NIR or UV, not VIS. While these objectives certainly cover portions of the VIS spectrum reasonably well,...

Re: Having Fun With the Opteka f/4 1:1 Wide Angle Macro Lens
Capital images, Mark--I can see how that lens would be fun. You're definitely creating images that most other photographers would neither envision nor be able to make. I wouldn't crop the damselfly shot--like it as is. I wonder how you got so close to that frog--did you sit very still and wait for h...

Re: Liquid lenses for focus stacking
Argu, One video creator you linked to is Ben Krasnow, who is among my favorite educator/experimenters on Youtube. Must admit that his explorations of building an electron microscope, and of refurbishing a derelict commercial electron microscope, dissuaded me from attempting such things myself. A sou...

Re: Windows of Papilio ulysses wing scale
David,
Thanks for your constructive criticism!
I appreciate it.
It's funny, how different brains process stereo. My brain can not see what David points out. But I'll try to make and post another pair adjusted per his suggestion. I'm new to stereo--this was my first.
