NOT AN ENTRY! I saw the theme, and immediately thought of this picture, which, alas, wouldn't qualify because it was taken well out of the qualifying period; and I doubt if I can recreate it, as it is not often that an airliner happens to fly over me at about this altitude, when I happen to...

Much to my surprise, my wife, @Seanette, expressed a willingness to be photographed while bathing, and for the resulting image to be posted here on this forum, subject to the restriction that it not show certain parts that would be covered by a swimsuit. This is farther than I would have...

I have it in my head that a typical electronic flash has a duration of anywhere from around 1/500 to 1/2000 of a second. I don't know where I got this figure, and I don't know whether it's true or not. I don't think any modern DSLR has shutter with a top speed of less than 1/4000 of a...

The thread about the Vivitar lens shows this, but perhaps not as well as one would like. It's particularly noticeable to me in the ƒ/8 pair, that the nearest pieces of candy are fairly sharp in the 85mm shot, but still very much out of focus in the 205mm shot. But the answer is that all...

Surely this hasn't always been true, and I don't know that it is now of most lenses, though you're probably right in characterizing it as being associated with lower-priced modern lenses. Back in the days of manual-only cameras, I think it would have been prohibitively difficult to manage...

And here is what I've come up with so far along that line. I didn't really think I wanted the human subject as far out of focus as the OP does in his vision, so I was able to use a shorter, but slower lens—my ancient 28mm ƒ/3.5 instead of my 50mm ƒ/1.4. I don't know whether the idea really...

You inspired me to try to take some experimental shots, more or less trying to recreate your project. I first tried using my stock 18-55mm on my D3200, and came to the conclusion that it's not possible, with that lens, to get what you seem to be seeking. I don't have a 35mm prime, but I do...

Last week, our freezer failed. After removing everything from it, and packing what was still deemed salvageable in dry ice, I disassembled it, and found the problem. There's a fan, with a simple shaded-coil induction motor, that when I turned it by hand, I found that it did not turn nearly as...

It's not at all out of the realm of normal possibility for someone to be able to handhold a camera at a tenth of a second, especially with VR. Some people are better than others and holding a camera still. I can consistently do so at 1/10 of a second without any trouble, even without VR...

These pictures indicate that linkage on one of my ancient non-AI lenses. That linkage has been on nearly all F-mount lenses since the beginning in 1959. Originally, it was just to allow the aperture to remain open while viewing through the viewfinder, and to be closed down to the selected...

Good question, with an obvious answer, and perhaps a clue to the problem. The body controls the lens' aperture by way of a mechanical linkage. The body decides what aperture it means to set, and moves that linkage accordingly. I very much doubt if there is any way for the body to know that...

I definitely do not mean any criticism of you. My criticism is toward a segment of society that creates “show animals” by breeding to emphasize certain characteristics deemed “desirable” in certain breeds, with little regard for the health and well-being of the resulting animals. Your cat...

Well, there was, but it got bought out by Apple a long time ago. In fact, MacOS X is derived from NeXT's operating system. https://en.wikipedia.org/wiki/NeXT

I had to look up to see just what sort of lenses you're talking about. The E series turns out to be a short-lived series of unusually cheap (for Nikon), low-quality (for Nikon) lenses. Q is a designation used with some pre-AI lenses to indicate that it had four optical elements. I am...

First entry—Me playing the fictionalized part of a creepy voyeur…

Third entry.

You weren't kidding about the short focus throw on this lens. As previously mentioned, it focuses slightly past infinity, as shown in the first picture. The second picture shows it focused all the way to its closest setting. For comparison, here's my ancient 1972-vintage non-AI 50mm...
