To continue boring you, this is what the Rayfact 90mm 4 micro looks like, all two pounds.
The outside cylinder rotates focusing the lens on what feels like a cam not a helicoid. two additional elements ride in cams as you focus the lens closer to change the element to element distance. Focusing feels like zooming a two ring zoom lens.
The aperture is set on the front ring, the rear ring indicates magnification, no numbers engraved for an industrial lens. Even the brand and model are just on a sticker, this on a lens that costs thousands new.
Bought it as a relative bargain as one of the more user friendly Rayfacts, with a magnification range I can use. For the casual user like me it offers nothing that a 105mm micro nikkor would not give you without the extra bulk and weight.
This lens was installed in some form of inspection equipment, probably a clean room as it has no dust, Lens had stickers locking aperture and focus, and that is what the silver knobs do as well.
Comes in many different mounts, this one is on an F mount but cannot be mounted on DSLR, it would hit the ai tab.
Have an adapter coming that will shorten the F to Z mount distance and let me focus it to infinity, just because.

I knew you would Leighton. That is one of my favorite cars too, I know the owner casually from speaking to him at the event, he is very friendly and has six classics that he rotates every Friday. He restored this GT-500 in the 80s, told me the paint was done in '86. Most of the cars are a labor of love and people bring them to share and get in people's appreciation the reward for their hard work restoring them. Occasionally a rich Del Mar resident's employee brings a car for show but that is the exception. This is not a paid event, money need not be paid nor is received, one just drives in, parks and enjoys. Only rule is for parking - 1975 or older, but this is easily waived for anything interesting. Not a concours either, it is as named, a cruise event. Cars run the gamut from original Cobras or Duesenbergs to rusted pick-ups.
The event is not as good as it was before the pandemic, but it is still here!
People who come also seem to enjoy the diversity of cars and people that show up, here is LONG post a sample of that:
This spring we had 3 or 4 pairs of Robins nesting in our cedars. One mother built a nest on a speaker mounted next to our sliding door. She was constantly sounding alarm calls, and had a great view into our kitchen window which was 4 feet away on a wall 90 degrees to her nest. She always seemed anxious, and she watched the other Robins raise their young, and teach them to listen for and catch worms. Then all the other Robins left, but she kept tending her nest. About a week ago she disappeared or gave up. Yesterday Barbara took her poorly placed nest down, and in it were three of the prettiest colored eggs. A kind of Mallard wing blue/green color that is just stunning. You can see a slight color difference between the D850 and the 5DS-R.

Robin eggs do have a beautiful color to them. The comparison between the Nikon and Canon is interesting. It may be a difference in focusing, but if you look at the nest material between the two, the Nikon has much more detail.
For science, you should crack one of the eggs open to see if it was even viable.
These are all focus stacked images - 9,6,9, and 5 frames respectively. It was necessary to get better DOF. The D850 set to 5260K, and 5DS-R set to 5200K WB. The true color to my eye was between the two, but it had a more iridescent glow - kind of like some shades of red present. The two black specks are bugs, and the white specks may bugs as well - or tiny chips caused by the mother bird turning the eggs. I'll crack one open in a day or two to find out. My theory is she skipped the fertilization step.

Well, focus stacked or not, if you look at the nest in the middle of the 3 eggs (first 2 images), it's obvious that the Nikon is sharper. Not sure what's going on.
Beast of a lens body Rafael. Can you tell if the front element, aperture and rear elements are all one unit? If it is and could be removed from the lens body it would be interesting to see if it could be mounted to a lens board and used in a technical camera like the Cambo Actus. Would open up all possibilities of uses with tilts, shifts, swings, macro, infinity and everything in between
Let me know if you get tired of it

I think that sharpness difference is my fault. Barbara cracked one open when we got home this evening. They were fertilized, but she says "they died early". She sat on them 4-5 weeks, and Barb claims they have a 12-14 day gestation.

James/Leighton, in my limited experience with focus stacking, it's not always precise and concise, and weird areas of softness and layer boundaries appear.
Scott, just love the placement of the people in your Williamsburg Trades series, and the timing of your exposures. That 35mm softens the environment just right too.
Great series Scott. Love the framing and the lighting. I have not been to Williamsburg in quite a while and I recall a lot of the places you have been shooting.

Williamsburg Trades. Thanks for looking.

Ok, that would explain that. I thought maybe the lens didn't like being on the Canon.
The eggs probably got too cold at some point which stopped the process.

Gale force wind more like!
The final ascent was in the clouds and the rain was hitting us sideways. It cleared for a bit but came back with a vengeance on the top part of the descent. Three seasons in one day. Grogu is my USB power brick btw.
