The Silette series' rangefinder models were called Super Silette. There was also an interchangeable lens rangefinder model called the Ambi Silette.
SOOC, only converted to JPG. Interesting to see the difference an FF sensor makes. It's actually acting as a wide angle lens.
One of my Fuji X-Pro1 bodies is broken. It will power up, take a few shots, and then shut down. When I try to turn it on, it sometimes gives a message that says to turn the camera off and try turning it on again. I have also noticed a large, diffuse, white defect in the upper right quadrant of the sensor.
I later concluded that I had damaged my sensor while shooting a solar eclipse. Rather than repairing the camera, I decided to replace it with a Fuji X-Pro2.
I came across this interesting comparison on the internet today. I'm toying with the idea of getting another compact camera and at present it's a toss up between the Sony 100 iii (still available though newer models have been released) and the not yet released Panasonic TZ90.
The Sony has a 1" sensor whilst the Panasonic has a 1/2.3" sensor; this is somewhat outweighed by the Panasonic's longer optical zoom range and more flexible screen.
Given the generally poor performance of my Ricoh GR4 (which has a 1/1.7'' sensor) compared with my iPhone 6 (1/3'' sensor) perhaps I don't need another compact camera anyway.
Scintillating glass optical fibers are the first viable medium for large-area, solid-state, thermal neutron sensors that have applications in national security, medicine, and materials research. Here, ultraviolet-induced fluorescence mimics scintillation.

"Magic Wire" is so called because of detecting proximity to antenna.
THE MAGIC WIRE
As shown in the diagram, the input tube is a type 6R7 duo-diode triode. The triode section forms the oscillator, in conjunction with the coil L1 which is center-tapped to the cathode. When the triode section is oscillating, the r.f. voltage developed from cathode to ground is impressed on the diode section, causing current to flow through R2 and making the diode plates negative with respect to ground. The control grid of the 25L6 power tube is connected to the diode plates of the 6R7 and consequently a negative bias is placed on the grid which reduces its plate current to a very low value. As soon as the triode ceases to oscillate, there is no longer any r.f. voltage applied to the diodes, the voltage drops and the 25L6 draws high plate current, causing the relay to operate.
It will be noted that no rectifier tube or filler circuit is required in this design, yet the instrument functions on either a.c. or d.c. On a.c., the 6R7 oscillations and the 25L6 draws plate current only on the positive half-cycles. This principle effects a considerable saving in construction cost and in the size of the instrument.
After the parts required have been obtained, the first step in building the unit is to make the chassis, which consists simply of a piece of 16-gauge aluminum or steel bent and drilled in accordance with the plan shown. The front panel, which is included with the standard 6 by 6 cabinet, is drilled and a hole and grommet are placed in the rear panel. The oscillator coil is made by winding 100 turns of No.28 d.c.c. wire on a one-inch bakelite tube 3-1/4 inches long. A tap is brought out at the center of the winding. When the winding has been completed, the entire coil is dipped in a hot half-and-half mixture of beeswax and paraffin to keep the winding in place and exclude moisture. The sensitivity of the outfit is largely dependent upon the efficiency of the coil, so it should be carefully made. C1 is mounted on a small piece of 1/8-inch bakelite, because it must be insulated from the panel.
Wire the chassis first, starting with the heater circuits. Do not connect in the power cord until all wiring has been completed. The shield of the 25L6 is connected to its cathode, the shield of the 6E7 to the heater terminal which goes directly to the line. When all the main wiring has been completed, bring the power cord through the rear panel hole, and solder the three terminals to the terminal strip. The antenna wire is brought in through a rubber-grommeted hole in the top of the cabinet and connected to the stator or plate terminal of C1. A knot in the wire will relieve any strain on this connection. Stranded wire is preferred for the antenna.
The capacitances of C1 and C2 are largely dependent upon the length of antenna wire desired. If only 4 or 5 feet are required, C2 may be omitted. On the other hand, if the wire exceeds 15 feet, C2 will have to be larger than the value given. If the capacitance of C1 were made large (say 150 mmf. or more), C2 could of course be omitted but then the adjustment would become too critical.
The relay employed is a 3,000-ohm plug-in type of standard manufacture. It is a double-pole model and will handle a non-inductive load of 100 watts. It is somewhat more sensitive than is required and any other good relay of 1,000 ohms or more resistance should be suitable. The capacitor, C4, is shunted across the relay coil to prevent chattering. It may be advisable, in some cases, to put a 0.1 mf. paper capacitor across the relay contacts to stop sparking on heavy loads. It is better practice, however, to use a separate power relay when operating any but light loads.
In operation, the antenna wire is strung out well away from grounded metal objects and a 110-volt lamp is plugged into the outlet on the panel. When the tubes have heated, the lamp should light when the antenna wire is touched. If it lights without touching the wire, C2 should be screwed down until the lamp goes out. These adjustments should be made with C1 about one-half mashed. The panel may then screwed in on the cabinet and final adjustment made. This is done by gradually adjusting the vernier knob of the dial until the light remains lit when adjusting but goes out when the hand is removed from the dial. This may be carried to a point where the light will flash as soon as one approaches within 3 feet of the wire or instrument. It is better not to aim for such sensitivity, though, since it will vary somewhat with line voltage. A good, practical and stable point is about six to fifteen minutes or so for the instrument to acquire a stable point of operation owing to its sensitivity.

While cleaning the sensor of my camera a while back I randomly got the idea to try taking a photo of my computer monitor without a lens attached just to see what would happen. This is what I got. I don't remember what I had on screen at the time to get these specific colors, but I thought it made for an interesting gradient.

The photographs in my set, "Weed Flower Micros," may appear to be close-ups of regular-sized flowers – they are not!
These are micro (macro) photos of tiny little flowers which bloom on ordinary weeds found in my lawn.
How tiny? The largest weed flower in the set is only, when measured across its widest part from petal tip to petal tip, 3/4" in diameter (19mm)!
Some of these miniscule flowers are so small that the entire blossom you are looking at is 1/4" in diameter (6mm)…or smaller! Again, that’s measuring from petal tip to petal tip across the widest part of the bloom!
The smallest part of a weed flower that I have managed to successfully shoot and achieve good detail in is a photo I made of a bud that measured LESS than 1/32" in diameter (0.7mm) across its widest part!
For size references I have included a photo of certain flowers and buds next to the head of an ordinary paper match, which dwarfs the blooms and buds.
It’s delightful to discover the beauty, complexity, and variety in something so small that it’s easily ignored, taken for granted, dismissed as a pest, or just downright difficult to see with the naked eye.
And it’s an even greater delight to realize that this incredible beauty has been growing wild in my lawn, year after year, right under my un-seeing eyes as I’ve repeatedly mown them down with my lawn mower, never realizing the unseen beauty that I was trampling under my feet.
I hope you enjoy viewing these as much as I do. I have a lot of fun making them for us to look at!

One of the ugly and probably ineffective chemical detection sensors deployed along the Mall. Along with other heavy-handed security measures like jersey barriers and planters, these continue to junk up our grand spaces, monuments and museums. It looks like a robot, perhaps a predecessor to R2D2? Photography is probably not encouraged.

Nikon D810 Photos Pro Women's Surfing Van's US Open Sports Photography Tamron SP 150-600mm F/5-6.3 Di VC USD !
I shot in DX mode which crops away the extra pixels and takes me 1.5X closer while allowing for up to 7 FPS with the Nikon D810's Nikon MB-D12 Battery Grip using the 8 AA battery option! 8 Duracels took me through around 3,000 shots no problem--maybe more! I was shooting at the equivalent of 900mm with the 1.5x crop factor! Pretty close! Had I gone with the Nikon D4s, I would have gotten 12 fps, but no DX crop factor, as the sensor has only around 14mp, compared to the d810's 36 megapixels! Sure the larger pixel size on the Nikon D4s full frame sensor comes in handy indoors or at night, but in the bright sun, there's more than enough light for the smaller pixels in crop mode! Sure we lose some pixels from the outer edges when shooting in DX crop mode, but most of those pixels would be cropped away in lightroom anyway. And the smaller files make the memory cards last longer, while also upping the FPS to 7 shots per second! Not quite 12 FPS, but still awesome and enough I felt!
What a beautiful way to test the Nikon D810 and Tamron 150-600mm zoom lens for sports photography!
