Officers, observers, scouts, liaison officers, enemy snipers, gun crews, trench mortars and machine guns, anti-tank rifleman and motorcycle skirmishers are to be his primary targets. He is capable of independent action under the most difficult conditions of battle. It clearly shows the importance the Red Army gave to the sniper in its ranks. The Soviet Union more so than any other combatant in W. II, used the sniper in the greatest numbers and capacities. The sniper was a key element in the doctrine and actions taken by the Red Army on a platoon or company basis. He served as the eyes and ears as well as the unseen soldier that bogged down and created fear amongst the enemy.

The special lenses necessary to project CinemaScope and other wide-screen films were expensive, difficult to use, and in short supply. This Panavision attachment allowed scores of theaters to adopt Cinemascope projection without costly equipment modifications. This combination of technical superiority and lower cost catapulted Panavision to the top echelon of optical technology for film projection. Encouraged by rapid success, Panavision introduced the Micro Panatar lens later that year.

The Micro Panatar allowed film labs to easily create non-anamorphic release prints from anamorphic negatives.

Summary Of Zeiss Trademarks: below is a collection of logos from articles and literature in the collection of Company Seven. These are the major logos and trade names that identified the companies, or some subsidiaries. This is not including all trade names (Contax, Contessa, etc.) or variants of the main trademark (Carl Zeiss London, etc.) that Zeiss companies employed.

The Memar and Silette focus by estimation. The Super Silette has rangefinder focusing. This is the original and simplest model apparently produced from until the early s. Sears advertised the Memar as “simplicity and quality at a low cost. It has an Agfa Apotar 45mm f3. Apertures go to f Focus is set by rotating the focus ring in front with focus from 3 feet to infinity. It is not a rangefinder – focus distance is set by estimation. Behind the focus ring is the shutter speed selection ring.

The aperture ring is behind that, closest to the camera. There is no light meter.

An excellent opportunity to collect high quality photographic prints and support this website. Sharpening Sharpening increases image contrast at boundaries. This enhances perceived sharpness and detail, although it doesn’t increase actual information content. Sharpening can be overdone: But the right amount definitely enhances an image. Although sharpening can be performed during the scan or in the digital camera, it is usually best done late in the image editing process.

A simple sharpening algorithm subtracts a fraction of two neighboring pixels from each pixel, as illustrated on the right. The thin black curve is the input to the sharpening algorithm: The thin red curve the impulse response that results from sharpening— the sum of the black curve and the two blue curves, normalized to the same amplitude as the input.

The thick black and red curves shifted up and left are the corresponding edge responses before and after sharpening. Ksharp is the sharpening constant related to the slider setting scanning or editing program. V is the shift used for sharpening. The sharpening algorithm has its own MTF.

It is produced and hosted as another way of expressing gratitude to those who have helped Company Seven prosper. With some of this content dating back to the times when slow dial-up Internet access was the norm, the article was originally text heavy because illustrations were by necessity kept simple and to a minimum. Over the decades we have, and will continue to, on occasion add this or that mention of or illustration of items in our archives and museum collection, this to break up the monotony of text, make corrections with much gratitude to Dr.

It was never our intent to write one comprehensive and all-encompassing history of Zeiss, that would require volumes to do it justice, but rather to explain why we at Company Seven remain grateful for and in awe of the achievements by Zeiss. From its inception through to the middle 19th century, lens making was a craft that was essentially passed on from generation to generation.

Innovations had typically resulted from trial and error experimentation; this was a costly and time consuming process that could not factor in all of the possible variables in lens making materials and design.

Back to ALPHABETICAL SEARCH (Survey compasses) – S – SALMOIRAGHI PROFILE – Angelo Salmoiraghi was an Italian engineer. He was the successor of Ignazio Porro and head of the Italian manufacturer and retailer of optical and survey materiel FILOTECNICA (Via Raffaello Sanzio no. 5 in Milan) created by the latter in (source: ).

The discipline applies to all animal eyes, whether human or not, since the practice and procedures are quite similar with respect to disease processes, while differences in anatomy or disease prevalence, whether subtle or substantial, may differentiate the two. It was believed, by Alcamaeon 5th century BC and others, that this fluid was the medium of vision and flowed from the eye to the brain by a tube.

Aristotle advanced such ideas with empiricism. He dissected the eyes of animals, and discovering three layers not two , found that the fluid was of a constant consistency with the lens forming or congealing after death, and the surrounding layers were seen to be juxtaposed. He and his contemporaries further put forth the existence of three tubes leading from the eye, not one. One tube from each eye met within the skull. The Greek physician Rufus of Ephesus 1st century AD recognised a more modern eye, with conjunctiva , extending as a fourth epithelial layer over the eye.

Celsus the Greek philosopher of the 2nd century AD gave a detailed description of cataract surgery by the couching method. The Greek physician Galen 2nd century AD remedied some mistakes including the curvature of the cornea and lens, the nature of the optic nerve, and the existence of a posterior chamber. Though this model was a roughly correct modern model of the eye, it contained errors.

Still, it was not advanced upon again until after Vesalius. A ciliary body was then discovered and the sclera, retina, choroid, and cornea were seen to meet at the same point. The two chambers were seen to hold the same fluid, as well as the lens being attached to the choroid.

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.

The failure of Google Glass has not been enough to put Apple off the idea, with a new rumor suggesting the iPhone maker is working on its own pair of augmented reality glasses.

Introduction Carl-Zeiss is one of the legendary brands in the business thanks to a history dating back to the very beginnings of the optical industry. Regarding the number the key designs it can almost be described as its cradle established in Zeiss remained active and successful in other optical markets inc. These classic lenses are designed in Germany but made by Cosina in Japan under Zeiss quality control. The original symmetrical Planar design was invented in ! In fact it is the most successful and most copied design in the business.

The lens is available for EOS as well but we used the Nikon version via adapter. The focus confirmation in the viewfinder remains active though and you can naturally use Live-View for focus fine-tuning. The build quality of the full-metal Zeiss brass with chromium-plated brass front bayonet just screams quality. The fluted focus ring feels exceptionally well damped. The lens does extend marginally when focusing towards close distances. The front element does not rotate. Specifications 7 elements in 6 groups Number of aperture blades.

Mark Baigent July 28, at AM. Hi David > But as the FF sensor surface area is ~2x bigger, and technology advances apply to all sensor sizes This is true but there are more variables than just size, ie the use of an AA filter that deliberately softened the image on my old 5D

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.

Full frame cameras are better. I started shooting personal work with my little Fuji.

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.
