New FD 100mm f/2.0 & FD 100mm f/2.8

 

A dual basic entry lenses into telephotography

Back in those days, zoom lenses were not as popular as they are today, especially so when most of the entry-level and midrange 35mm SLR cameras of any brand were bundled with the 50mm standard lens.

And for first time buyers of such kits, their choice of a second lens were likely be a telephoto type. Strangely, the 80-135mm focal lengths were the most popular. The 100mm focal length still falls into this category of medium telephoto, but the size of the image on film is considerably larger than that of the standard 50mm. Its angle of view is about half that of a 50mm lens.The 100mm fills the 35mm frame with one quarter of the area that would be included in the same scene made with a 50mm lens.

The 100mm is perhaps the first telephoto where the difference in image size on film becomes apparent. While there is some perspective compression it's not overpowering. And this could be the reason why a photographer that is used to the "ordinary" view of a 50mm lens, finds it to be very appealing when he/she is to view through the eyepiece with the 100mm focal length for the first time. However, the depth-of-field of the 100mm lens is substantially less than that of the 50mm lens at the same focusing distance and aperture which contributes to a very pleasing visual when compared with lenses of standard focal lengths.

The 100mm focal length is a basic telephoto that will produce strong images of a wide variety of subjects and is a good choice as your first telephoto. While careful focusing is always important, the depth-of-field of the 100mm lens at smaller apertures helps overcome minor focusing errors - particularly important when shooting fast action where most of the time higher shutter speed settings are required (unless you wish to use slower speeds to portray a sense of motion).

The 100mm lens provides great versatility, favored for casual shooting, serious portraiture, sports or commercial work and landscape? Great for isolating a portion of a scene and the slight compression of perspective gives a striking sense of depth to both scenery and landscape pictures.

There are two options in the Canon FD lenses. The New FD 100mm f/2.8 or the faster speed of the New FD 100mm f/2.0, both of which are capable of handling the demands required for low light situations. One of the most interesting aspects of the 100mm lens is the ability it gives you to control sharpness in both foreground and background. This can be particularly effective when photographing people.

Front, back and side view of a New FD 100mm f2.0 lens. Combining some very logical reasons like compactness in size, light weight and solidly built with very high optical performance and still comes with a price tag that does not burst a hole in your pocket or wallet.
By making only the main subject of the image sharp, you direct the viewer to the important area of the picture. In addition, photographers favor the 100mm for commercial shooting not only in the studio but on location as well. The ability to fill the frame and the pleasing perspective are important advantages with the 100mm where subjects are small and have a lot of details. The 100mm focal length is also a fine snapshot lens because it allows the photographer to keep a comfortable distance between him/her and the subject in order to retain the natural facial expression. While depth-of-field is shallow enough for special effects, it is not so shallow that focus is absolutely critical. With virtually endless versatility, it will handle a multitude of subjects - sports, scenic, nature and people photography.

The far left was seen with the dedicated hood (standard accessory supplied) reversed and store before the cap is put on. One would expect the 100mm lens would come with a built-in telescopic lens hood. The hood pictured at left is not a metal hood but nevertheless it is light and could be cheap if you have misplaced it. But I am not that sure if Canon still keep hoods like this in stock or the EF lenses can shared their hoods with the FD versions.

But if you do a lot of half body length or head and shoulder portraits, this lens can be much more versatile than the 135 or even the 200mm lenses as you need not to move backward a lot. However, if it demands more than just head and shoulder shots, or when working at full length portraits, the f2.0 version offers a broader scope for lower light shooting or using slower ISO film speeds.

In choosing between the maximum apertures of the two lenses, it relates directly down to the price. The f2.0 version costs almost double that of the f2.8. First, you will have one stop of shallower depth-of-field control with the f2.0 version plus a slight advantage when shooting in dim light situation, However, with today's fine grain high speed film, I think the doubling of the cost is a little too excessive for justification. Lastly, there is a choice of having an FDn bayonet type or the older versions with chrome, breech lock mount rings, that can also be considered if you are looking for one in the used market.

Canonn FDN 100mm f/2
New FD 100mm f/2.0 Lens

Despite its fast speed of f/2.0, this lens is kept reasonably compact and lightweight. It produces high quality images from its f/2 full aperture by sufficiently restraining spherical and chromatic aberrations.

Should be a good choice for stage, or low level of available light photography. The extra stop provide greater control of depth of field. It is well made and balance very well in hand.

100mmf28shutterbladB.jpg
New FD 100mm f/2.8 Lens

This lens is composed of 5 groups and 5 elements without using a single cemented lens. It is very small in size and light weight.

The elements are properly arranged, handling is well-balanced and the lens on the front end is made thick. A very popular and reasonably priced lens for new photographers who are looking for a second lens other than the standard 50mm lens. The bright f2.8 is indeed luxurious enough when compared with most slow speed zoom lenses.
