It’s awesome those new glasses work so well for you!!!! Just experienced my first foray into bifocals; and I must say the experience is exhilarating! Let me start by going over my background. Failed my vision screening in the 5th grade and subsequently went to an optometrist and was diagnosed with nearsightedness. I wanted glasses so bad I was so happy on the inside that my eyes were nearsighted. Was prescribed glasses for distance only and parents did not want me wearing them. This went on for about 18 months when my mom made a comment about me squinting at the tv and told me I should consider wearing my glasses. Even though I wanted to so bad I was reluctant to wear them outside of the house. I continued to struggle with reading the blackboard at school but did finally get another exam and needed a stronger prescription. I finally had to use them part-time at school now.

I am eager to see what Leica has up its sleeve, not least because I still have several film bodies and some wonderful Leica M lenses. Some lunatic would have stuck black tape over the Leica dot. So what has happened since I write the first article? Not a huge amount, but that in itself is fairly significant. It is also exceedingly expensive for a long lens that is not mated to a system with obvious professional utility such as for wildlife or sports.

When you consider that I wrote Leica SL: Titan or Titanic in October , that is quite a wait for the first prime lens and only the third lens in the line up. The next issue is to expand upon the size and weight issues I talked about in my earlier article. Comparison with Nikon would be broadly comparable, depending on the body and specific lenses chosen. If any of you were hoping that native primes might be a little smaller, you may be disappointed.

The camera body is made of mahogany wood and has the shape of a flat box somewhat like a brick with the dimensions of x 45 x 85 mm. The camera weighs grams. It accepts a maximun of 20 m of perforated 35 mm film, enough for apprximately exposures. The format is 24 x 60 mm. Courtesy for text and picture Mr.

The invention of the camera in the early 19th century led to an array of lens designs intended for problems of photographic lens design, creating a lens for a task that would cover a large, flat image plane, were well known even before the invention of photography due to the development of lenses to work with the focal plane of the camera obscura.

I have said, in the past, that you should move toward full frame sensors. I have always championed full frame sensors. At the end of the day, full frame sensors beat APS sized and smaller sensors. The whole reason I bought an original x was because it had the largest sensor I could find in a small camera. It had been a number of years since I had shot an APS crop frame sensor. I replaced that with a Nikon D3 full frame and then moved on to the Canon 5d2, also full frame.

A Carl Zeiss teaching eyepiece adapter. The central eyepiece fits into the standard eyetube of any monocular microscope. It has a pointer system that can be introduced into the field of view and moved to point out specific parts of the slide being studied. On the end of the side tube is a second eyepiece which has independent focusing which ensures the image is in focus for both observers.

Date from approximately but still works perfectly.

Soft front light / hot backlight. A popular technique in film lighting is to use a soft (diffuse) light source from the front and a stronger, more directional light from the back, so that your subject has a hot soft frontal light is known as the fill light; the strong light at the back is known, unsurprisingly, as the backlight.. You can arrange the lights in such a way as to leave.

The soft frontal light is known as the fill light; the strong light at the back is known, unsurprisingly, as the backlight. You can arrange the lights in such a way as to leave darkness between the area illuminated by the backlight and the area illuminated by the fill light, depending on how moody you want the shot to be. This tends to work very well, although even the moodiest films tend to avoid leaving dark shadows on the faces of female talent. For a slightly different look, the backlight can also be soft, but it should still be hotter than the fill.

You should light your film or video shot by shot. This means that when you relocate the camera to shoot a different angle, the lights must be moved as well to ensure the subject is always lit correctly. This is partly why films take so long to shoot.

The first set of objectives rightly honors the Tessar type project. The first example we consider brings us back to photography adolescent dawn: At the same time the famous Burgess Shales were discovered in British Columbia, with their exceptional Cambrian fauna preserved so well that, for the first time, we studied the soft parts of the trilobites, a distant event which now belongs to the history of paleontology. The ferrule which keeps the rear doublet can be unscrewed, thanks to a knurled power take on the bottom of the lens, while the two individual lenses are removable together, unscrewing the black front rim, in turn separable into two pieces by removing the central lens, screwed on the back of the removed ring: I have performed preliminary tests with this lens, and do not hide the emotion felt in reviving such a dated, historical piece: Marco in Venice, after the collapse of , was inaugurated with great pomp: The lens proposed here with the main statements of his patent, registered in April , is small in size and was originally fitted to a mahogany wood plate; the barrel is made of burnished brass and, as usual, the stopping-down references for the iris actually indicate the diaphragm hole in millimeters; notice how the data in the front ring are manually carved, removing the black lacquer and displaying the bare brass.

Mike’s Guide to Buying Old Cameras

My Photographic Beginnings The first camera that I owned was a Kodak Brownie that was a present given to me by my brother Jim when I was about ten years old. I used the camera for family photographs but not for “serious” photographs and very few images survive that were taken on this camera. This was replaced a few years later by another camera It also and had an accessory shoe and sync socket allowing use of a flash unit.

Needless to say his interest rubbed off on me. I only had a couple of accessories to start off with

“The principal task of the sniper is the destruction of the most important enemy targets he can find.

A telephoto lens is made physically shorter than its nominal focal length by pairing a front positive imaging cell with a rear magnifying negative cell. The powerful front group over-refracts the image, the rear restores the focal plane, thereby greatly shortening the back-focus length. The Barlow lens, a negative achromat magnifier invented by Peter Barlow in , is still sold to increase the eyepiece magnification of amateur telescopes.

Primacy was never established and no patent was ever granted for the first telephoto lens. The cell spacing was also tunable, because that could be used to adjust the effective focal length, but that only worsened aberration problems. The Protar was originally called the Anastigmat, but that descriptive term quickly became generic and the lens was given a fanciful name in Schott glasses have higher refractive index than soda-lime crown glass without higher dispersion.

The Protar’s front achromat used older glass, but the rear achromat used high index glass. The primary exceptions are deliberately “soft-focus” portrait lenses.

Is The Leica SL Doomed?

Developing My first bit of advice is to figure out whether or not you want to buy and use these cameras, or simply display them on a shelf. The number of people shooting film has significantly decreased in the last 15 or so years, but there is still enough of a loyal following that it is still possible to get film cheaply. If you have no interest in actually using old cameras, then by all means go hog wild and just buy anything you think looks cool.

However, if you want to shoot film, you need to be a little more discriminate. Types of Film and What to Avoid Not including instant film formats like Polaroid and a couple very obscure formats that are hard to find and extremely expensive, there are two primary formats of film that are still readily available.

Govt Surplus “Hot” Cameras and Lenses You will find two kinds of radioactive lenses – those that were contaminated and sold as government surplus, and those that are naturally “hot” or radioactive due to the radioactive elements or radioactive impurities used in their manufacture.

If you want to buy some slightly radioactive lenses and cameras, the U. Government has a lot of them for sale – cheap!. Maybe some of those bargains you got on EBAY are “hot” in a different sense than you might have thought! I am assuming that heavily contaminated and radioactive government surplus items end up in government low level radioactive waste land-fills or other burial sites.

So if your government surplus bargain camera or lens is contaminated, it is probably only “lightly” contaminated. That’s good news, I guess? Our main focus here is not on contaminated lenses or cameras, but on naturally radioactive or “hot” lenses due to the materials used in their manufacture. These slightly radioactive elements such as thorium or rare earth elements such as lanthanum were used to produce desired highly refractive glasses.
