More Barbara creations. A caramel covered puff pastry with apricot glazed peaches and raspberries. Next, a lemon cheese cake that was amazing even with an error only she knows about. Then the lens cap to the 24mm f2.8 ais that was used on the D800 + the tc16a.
Jim, lemon is fruit. Sugar comes from beets which is a vegetable right? All natural, like a friend used to say; even the "artificial" stuff is made from the 118 basic elements that are found "naturally"
Phong, beautiful night scene bridge shot. As for FB, the rest of the gang may go for it, I personally don't maintain a FB presence. As long as it's not private group and not a full repeat of images here I'll visit occasionally.
Laura, I really enjoyed this last group of closer up details of the Hartman work.

Thanks Ray. Yes I am pretty sure you can do the same multi-exposure in the Z cameras.
Below is a link to an old article on NikonUSA by Moose Peterson describing what I did with the Df.

I haven't been to the Washington edition of the Air and Space since ages! Was that recent? I know there has been a lot of renovation going on there.
The renovation still going on. I took this pic last Friday.

Thank you for the compliment Serge, but most of all thanks for sharing your travels! very interesting stories from history.
Did some "tests" with the new Tochigi Rayfact 90mm. Lens is big and heavy, to a casual photographer like me it does not add anything from using a 105mm Micro, it actually detracts from the experience due to bulk and weight.
On the other hand the lens is ugly esthetically but beautiful to an engineer with formal optics training (U of A, Tucson) all metal is overdesigned with big helicoid and individual tracks for several elements to keep it all aligned and spaced properly, many element relative positions change as you focus.
Detail/sharpness appears exceptional, but it does have axial color, kind of makes sense for a lens designed for planar sharpness to measure/inspect flat objects like printed circuit boards.
I wont sell it, but may not use it much either, we will see.
I am not qualified to test this lens, these are casual tests. Actually, take that back - I am qualified to test this lens but my current job has no access to an optical bench.
This ebay photo show the lens at maximum magnification, the front element is 52mm diameter - that should give you a sense of the bulk of the metal. That front retracts all the way into the metal cylinder when focused further away, The outer cylinder is the focusing ring, with no knurling or rubber, it is meant to be focused once when assembling a test station and has knobs to fix focus and aperture once set.
The next few are at minimum focus which is 0.5X and maybe a foot away. They really need to be seen 100%. Take into account that I cannot get perfect alignment in pointing the lens.
Raphael, I am shocked I tell you, just shocked. UofA Tucson? For real? And all these years I never even suspected. You really are a great and talented guy anyway though.

Mary (aka ASU Chic)
Mary, I feel a need to clarify, my degrees are B.S and M.S in EECS from UC Berkeley, MBA from Pepperdine, at U of A Tucson I spent many weeks over summers (warm but fun!) taking optics courses as I was working in a past life in a radial artery fiber optic catheter that measured blood gases, pH and temperature continuously; using fluorescent chemical sensors on the tip of the fibers. My part in that was the design of the optical train, the beam handling and spectral design. I did have an optical lab with an optical bench and a lot of beam forming equipment, my own spectral and surface measurement interferometers, much fun to be had. Also developed the algorithms for calibration and transduction, all this work was approved by the FDA for use in people.
As an old man I can look back and know it all happened as part of a larger effort and be grateful, same as my current work. As manufacturing left California I moved onto supporting the Navy ships as they are staying in San Diego Bay.
Best of all is that I worked half a mile from the Beach in Carlsbad for 20 years and surfed anytime I wanted to, got changed into the wetsuit at work!
Rafael,I was just kidding you. You have had a most amazing life and tour of duty, and most importantly, don't forget the photography part! I could not pass up a comment regarding the U of A, my alma mater's collegiate state arch rival. The only consolation we "Sun Devils" have is that the "Wildcats" suck almost as badly as we do at football these days! Pity the coach of the loosing team in the last game of the season when the State rivalry matchup takes place each year.
Went out this morning before it got too hot. Still have poor air quality warnings in my area due to the Canadian forest fires, but the cool forest shade made it a pleasant time. These are all defished 16mm f3.5 ai shots with the D850. The LR lens profile does a decent job, but it stretches the corners and edges too much trying to salvage as much image area as possible. I'll try my PS plugin sometime and see if it does any better. Last shot was using one of the three built in filters on the 16mm - in this case red. Looks like it will make a good in camera black and white starting point.
