LENSES, LENSES

All cameras contain a lens which is comprised of one or more "lens elements."  The lens elements aims to direct the path of light rays such that they recreate the image as accurately as possible on the photographic film either on the digital sensor.

Camera lenses could be categorized as fixed focal prime lenses, variable focal zoom lenses and special lenses with a ability of shifting, tilting etc. Another classification principle is to divide lenses to normal, wide angle, telephoto and zoom lenses and why not in generic versus third-party lenses. This or that, they all try to project a picture of a reality on the light responsive plate.

Tamron 500 Tamron SP (55BB) F8 / 500mm Mirror lens

Adaptall 2 Mount

Discontinued in 2005 is still available for most SLR cameras. Ebay is a place where you can get one today.

I bougt this lens in early Eighties and I thought that I will have plenty of use of it. Well, it is a good performer and most of all it is easy to carry (560g), compared to a conventional 500mm telephoto lens. Its "bukeh" with those bagels is a matter of taste.

Tamron 24
Tamron (01B) F 2,5 / 24mm

An excellent Wide Angle lens. Sharp, contrasty and well corrected. Adaptall mount makes it usable almost in any SLR camera. Optical construction consists 10 elements in 9 groups, filters size 55mm, weight 230g.

Tamron 28-50Tamron (07A) F 3,5 - 4,5 28 - 50mm

Compact "everyday" zoom, smal enough to fit in the most normal ever-ready cases.Nine elements in nine groups and a continuous focusing (CF) to the macro mode. Filter size 58mm, Weight ~300g.

Tamron is one of the most remakable "third party"after market lens manufacturers in the world. The company was established in 1950 as a Taisei Optical Equipment Manufacturing. In 1970 the company name was changed to Tamron Co., Ltd.

Tamron Co., Ltd. is also a major producer of OEM products and a large variety of optical devices and components.Tamron

Tamron 70-210 Tamron SP (19AH) F 3,5 / 70 - 210mm Zoom

Big and heavy (850g), therefore it is not the most convenient to carry but you get excellent results with it.. When I bougt this in the early eighties it was just released and was later proofed to be one of the best Non-Mfg (not a camera manufacturer, a third party, pirate, what ever) zoom lens on the market. It is a quality-exemplar of Tamron SP "Super Performance" series of lenses. Optical design consists of 15 lens-elements in 11 groups, filter size 62mm, weight 860g.

Vivitar Macro Focusing Teleconverter

Vivitar F 2,8 / 135mm + Vivitar Macro Focusing Teleconverter (The lens is obviously made by Komine to Vivitar's specifications. Vivitar did not own their own lens factory they might design the lenses but used subcontractors to make the products. )

I have proven this combination and I should say: "Not Bad". The Macro Focusing Teleconverter and the 135mm short tele are so called "Custom Fitted" and they are working really well together. Something has to be wrong in the idea, because I have not seen this kind of Tele- Converter and Macro-Tube combination elsewhere.

Summicron
Rikenon zoom

 

XR Rikenon Zoom 1:3,5 35 ~ 70mm Macro

Ricoh Co., Ltd. was founded in 1936 by Kiyoshi Ichimura. Ichimura's first major innovation was the RicohFlex III. Introduced in 1950, the world's first mass-produced twin-lens reflex camera in the world. Ichimura also developed a sense of corporate social responsibility and genuine commitment to social and environmental sustainability in every aspect of Ricoh's business activities.

Today, as a global company, Ricoh is a a global leader in digital office solutions, copiers etc.

The newly-designed XR Rikenon lenses open up a world of creative possibilities. From super-telephoto to macro, plus a wide choice of specialized accessories, the highest quality and performance is on your side. (From Ricoh lens brochure)

Leica Summicron R 1:2/50 "Outstanding imaging performance across the entire field, with uniformly high resolving power and brilliance."

A versatile standard lens that demonstrates its outstanding imaging quality at mid-range and close-up distances as well. Despite its high speed, its sharpness of focus, contrast and detail resolution are first class even when shooting wide open at f/2. Weighing just 300 grams (10.5 oz) and just 41 mm (1.6 in) long, it is extremely handy and compact.

Hexanon 50mm

Konica Hexanon 50mm f/1.7

This 50mm f/1.7 had a construction of six elements in five groups. Weight is 8.5 ounces. Filter size is 55mm. Aperture Range: f/1.7-16.

Celestron C 90 1000mm f/11 Maksutov TELESCOPE.

Cassegrain - Maksutov type telescope uses a spherical corrector lens for a more compact catadioptric lens than the former constructions.

In 1957, an optical engineer, John Gregory, developed further refinements in the Maksutov-Cassegrain design. Most notably he did away with the separate secondary mirror and replaced it with a mirrored spot on the corrector shell itself and this is how it is, concerning of this Celestron Telescope.

Here it is equiped with a Konica AR adapter. The aperture is constant f/11 but you can read the correct exposure time with the camera, so it is not a problem. The tiny tripod in the picture is for an "artistic" appearance only. This kind of lens with an ~1.4deg. angle of view needs a steady tripod or some alternative rest to ensure crisp vibration free pictures. (thxZygmunt)

*Konica SLR lenses 1960-1987*

 

"Over the years, Konica had extended their lens line-up to meet professional demands. From fisheye to extreme long telephoto lenses everything what a photographer desires was available in the mid-70s – most of the lenses in outstandig quality, optically and mechanically alike."

Celestron

 

Russian Mir -1 1:2.8 - 37 mm wide angle lens. It has six elements in five groups. The overall look is better than what I have red about it's performance. Anyway, it got a Grand Prix in Brussel 1958. Both L39 and M42 mount lenses were made in ZOMZ, Optico-Mechanical Factory, Zagorsk.

Best description about a lens is on the Alfred Klomp's page HERE
