Watch the sidelines at the next professional sporting event you attend or watch on TV. Look for the identifying L-lens red stripe around the end of the photographers’ camera lenses. These are the people who make a living with their equipment – and they frequently trust the CanonL Lens Series for their income. About their L lenses, Canon says “these lenses use special optical technologies [such as] Ultra-low Dispersion UD glass, Super Low Dispersion glass, Fluorite elements, and Aspherical elements to truly push the optical envelope.

What you can get when you use Canon L lenses if you do your part right are amazing pictures. In fact, this amazement is said to cause a disease know as “L-Disease”. Once caught, it is incurable. You will have to buy Canon L lenses in all of the focal lengths you use. AND you will be happy and I hope you know that I am not being totally serious. Both lenses have Wimberley P20 Lens Plates mounted on their tripod rings.

Canon L lenses generally come with a lens hood included. Canon L lenses are top quality pieces throughout the line. They typically have wide apertures fixed throughout the zoom range for most L zoom lenses.

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. You set the shutter speed and aperture by estimation or a separate light meter. Film advance is with a lever, something fairly advanced for this level of camera at the time.

The film advance cocks the shutter and also increases the exposure count.

As I have mentioned above, Canon has been placing date codes on their lenses for a long time and previously many lenses had the date code placed separate from the actual serial number.

In , Canon started placing date codes on select lenses only. Click here to see the list of non-L lenses that have date codes post if your non-L lens is not on this list, then you are out of luck. You can find this code on the inner rim of the lens the side that attaches to the camera.

History of photographic lens design

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.

This section contains over 70 still cameras from A to Z (Agfa to Zeiss Ikon) using 35mm film but not having single lens reflex viewing and focusing.

The architectural photographer who captures futuristic buildings and breathtaking enfilades is standing in an ordinary garage. The austere, white room in central Lisbon is one of the most important places in his life. The garage is located on a little side street; an inconspicuous entrance with an electric door leads inside. The special thing about this decidedly ordinary location: He finds the garage calming, a place where he can leave his work behind and clear his head, says Guerra.

The images explore the idea of sacred geometries, the perfect mix of proportion and mathematical ratios that are pleasing to the eye and a reflection of those found in nature. Geometry in aesthetics are unavoidable when traversing through the city, whether this is in grand scale such as skyscraper architecture, to the tiny backs of ladybirds. Intricate design can be located in both complex, constructed design patterns and in the minute details in nature. Aesthetics and mathematics come together in geometry, and have done since ancient Egypt, where geometrics were viewed as a visual manifestation of law and order.

We observed shutter-shock blurring with single-shot and anti-shock modes from both lenses. There’s slightly more the wider the aperture is, but it’s an extremely minor increase. Maximum measured CA was under three hundredths of a percent of frame height, but on average, CA is nearly zero. Comparing our lab test images, there is very little difference in CA with and without the extender, though there is a subtle “hue” of purple in the far corners.

Shading ”Vignetting” With a supertelephoto lens, we weren’t expecting much in the way of vignetting, and this is indeed the case with the Olympus mm.

Tōkyō Kōgaku, later Topcon, is a Japanese optical manufacturer, previously a manufacturer of photographic equipment.

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. Then I pulled it out on jobs from time to time because I loved that little camera.
