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 ...

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...

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...

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. . . .)

(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...

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...

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...

I received an email from Fotodiox, introducing a new product: " Fusion Smart AF Adapter for Canon EF/EF-S Lenses to Nikon Z-mount Bodies "Looking for more lenses for your Nikon Z camera? Grab a Fusion adapter and some EF mount glass to fill the gaps! Check out the latest addition to our line of Fusi...

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...

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,...

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...

Really thorough and thoughtful review, Mark. Thanks for posting it.

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...

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.

Henry,

I don't have what you're looking for, but do have the following. Are any of them close enough to be helpful?
