Pulled out the Vivitar Series-1 200mm โˆฑ 3.0

Found this guy while trollin' around. Much more comprehensive articles, in-depth repair techniques on the rest of his site as well:

 
I hope to never deal with fungus. Even working inside a virgin dry cleaning bag to replace a focus screen still got dust inside the view finder.

I'd seen fungus in a Leitz lens as a kid, a local doctor would spend time here in Florida during the winters and had his Leica along. I'd no idea it was possible for anything to grow on optics. Scared th' heck outta me. Now I'm a victim.

Surprised to find no ammonia in the local Publix stores, thought we had a jug here but nothin' found. So my 'phungus project' is delayed.

As for dust, GAH! I even got out the old "StaticMaster" brush to dust off anything on the scanner and negs and still have the traces in the scans. About choked seeing the cost of those things now, too!
 
Tentative trial of th' Ox Snot on an old Canon Scoopic UV filter, used a Q-Tip and soaked the swab and applied the stuff repeatedly. It worked! Now cranking up the ambition to tackle the disassembly of a couple primes.
 
I'm one and one just now. The 18~140 DX AF had a spot on the edge of the second element in. A dot smaller than a pinhead with "stuff" radiating out to about 1/4" diameter. Decided that was priority, removed the front element and treated the invader. The Ox Snot worked as advertised, again the Q-Tip soaked and applied repeatedly. Cleaned well with alcohol on swabs, inside front element as well, and reassembled & checked. ๐Ÿ‘

On to the 200mm: Had a time getting 40 year old setscrews to cooperate, went in from the mount end as far as I could but unable to get the front element retainer to budge. Spent a couple hours on it, got whatever was on the rear element treated but decided to reassemble and try again another day.

No trophy for me.
 
The DX element "infestation":

Okay, NOW for the trophy. 200mm lens apart, cleaned front three elements of the debris:

The resultant shot after reassembly, same flower bunch, full frame and cropped a LOT. Hand-held, 500th at โˆฑ11. I call it a success.

The fly as a bonus bokeh... :LOL:

A couple more hand-held with the D7200, the 200mm, 20' distance, โˆฑ11 @ 650 sec. (ISO 800) for the first one. Second at 40' with โˆฑ8.5 @500th, same ISO:

OK, no more shots of concrete. I was going to suggest Elgin AFB to photograph the SR-71 but that looks like it is over 400 miles from you. Dang I just looked and have 6 closer to me than that.

Alright. No more concrete. It was only to check sharpness anyway.

Have you ever seen a shot of the SR-71 with the Playboy Bunny on the tail over desert? If so, check the by-line. Two shots made into lithograph series. Two different photogs.
 
I'm not sure what I'm looking for but I found this. This video has photos taken by major Brian Shul. Right up your alley in so many ways.
 
"Rapid Rabbit" SR-71. Only one lost to a crash landing, at Kadina. Both guys walked away. Lockheed had used it early on as a "glamour model" for photos.

The litho series photo I referenced was shot by a SSgt Richard Jackson, durn'd if I can find it on the 'net tho. Rich was another of our AAVS co-workers. Most of the "Photo: Courtesy U.S. Air Force" by-lines were shot by one of us Still Photo weenies. Rich was among the first bunch of us to make enough noise for individual recognition. Finally Airman Magazine got on board with it.

In March of '72 another guy and I went on a TDY to Burlington, VT to photo the GAU-8A test firing. In the "shop" there was a crusty old TSgt working with G.E. He had a white coffee mug with a Blackbird graphic on it in black outline with a big "3+" in red over the graphic. We asked him if that were true, he was evasive but grinned. Found out he'd been part of a Habu team. Back then nobody "outside" knew what the 'bird could do, all that was Classified info. We were given these "Mementos" on that trip, the raised portions were originally gold but years on my toolbox have taken a toll. "Fridge" magnets about the diameter of a half-dollar coin. S'posed to be a tank blowin' up in the gunsight.

I knew one of the SRO's, met him in about '94. Conrad Seagroves. He'd retired and settled here in the area. Had some good conversations with him. Cancer got him about a decade ago.
 
I can see myself trying to photograph that beast. "Can we do that again? I think I had motion blur. Anyone seen me shoes?"

You'd get a laugh from the details! Thought I'd put them out someplace here before. The concussion wave alone was impressive, to say th' least.
