Zoom lenses really started to come into their own by the late-1970s and became standard equipment with most SLRs by the mid-'80s. Versatility was the name of the game, with such optics sometimes enabling a photographer to replace up to 3 primes with one lens. However, this was not a free lunch; there were always compromises involved.
Welcome to Part 2 of Choosing Manual Focus Lenses. We will now delve deeper into the categories of focal lengths and the differences between them. As in the previous post, we will be looking at this in terms of vintage 35mm format manual focus (MF) lenses, but you can use the principles for more modern glass and other formats. WARNING - There may some numbers involved! (I'll try to control myself ;-))
Fun With Focal Lengths
In 35mm format: "Normal" lenses range from 40 - 58mm (with 50mm being by far the most common and was the basic kit lens offered with SLRs for years); Wide-angles go from about 28 - 35mm; Extreme wide angles from 15 - 25mm; Ultra-wide angles are less than 15mm; Telephotos from 65 - 300mm; and Super Telephotos are greater than 300mm. All of these categories are approximate, but you get the general idea. We will look at single focal-lengths and, in the next article, discuss how zooms combine several focal lengths into one lens and the advantages/disadvantages of doing so.
One of the most daunting experiences for an SLR owner can be deciding which lenses to choose to achieve their photographic goals. The sheer number of possibilities can seem overwhelming when trying to narrow things down to a manageable kit, both expense- and weight-wise. Further complicating matters is that what works well for someone else may be entirely different than what will be best for you. Choosing lenses goes beyond mere quantitative measurements. Your aesthetic sense of how you see the world around you, along with the genres of photography you pursue, and the conditions you will be working in all have a direct bearing on which lenses will be most suitable for you.
Too many of us have learned the hard way about which lenses are best suited to our needs and abilities. Trial and error does often eventually lead us to the right conclusions, but with a considerable amount of wasted time, energy, and MONEY. Could there be a better way?
Welcome to the fourth installment of our "Choosing a Vintage SLR System" overviews! It features Olympus, one of the most influential Japanese camera manufacturers. We will work our way through: 1) Lenses, 2) Bodies, 3) Flash, 4) Accessories, and 5) Reliability & Servicing. But first...a little introduction :-).
Olympus first came to prominence in photography in the late 1950s and early '60s with their half-frame (18x24mm, which was half of the 35mm frame) Pen series of cameras specifically targeted at the Japanese and later, the European markets. They were designed to be affordable for the average worker and economical to operate while still providing decent quality for an 8x10 print. Olympus sold millions of Pens. Ironically, it was the refusal of Kodak to support the half-frame format in the USA that pushed Olympus into the 35mm arena. For a more in-depth look at this turn of events, see this article. Although Olympus was the last of the major Japanese manufacturers to get into the 35mm SLR game, they made quite the splash in 1972 when they finally joined the fray. The immense influence Olympus exerted on the photographic world was due, in large part, to the efforts of the brilliant designer Yoshihisa Maitani and his team of engineers. The creator of the Pen and OM series was always seeking to do something different, not just copy others, and this does much to explain the success of Olympus over a three-decade period with its film-based equipment. The OM series would do more to reduce the size and weight of 35mm SLRs than any other system. What is more interesting was the impact this had on the other, more well-established manufacturers (Canon, Minolta, Nikon, & Pentax) known as the "Big 4". By the late-'70s, that designation had to be changed to the "Big 5", due to the success of the OMs. So let's take a closer look at all the OM system has to offer.
The impact of a leap in technology is often best measured in the reaction of one's competitors rather than only in market-share or some other basic metric. The Olympus OM series of SLRs are a case in point. While Olympus certainly did grab a nice chunk of market share in the mid 1970's, it was the changes that their fellow manufacturers made in their own designs that define the introduction of the OM-1 as a pivotal point in SLR history.
Within five years of the introduction of the mechanical OM-1, followed two years later by the electronic OM-2, the other members of the now Big 5 (Minolta, Pentax, Nikon, and Canon) had all brought out their own downsized and/or lighter-weight models. Five years seems like an eternity in today's marketplace, but back then product cycles normally lasted much longer. Take, for instance, the Pentax Spotmatic. Introduced in 1964, with slight updates in 1971 and 1973, it maintained its layout and dimensions and gained 20 grams of weight until its discontinuation in 1976, 12 years later. The Minolta SR-T 101, which came out in 1966, was produced in the same basic form for 15 years. For over 14 years, the Nikon F hardly changed. Product development also took much longer, without all of the computer modelling and simulation available today. Prototypes were hand-built and tested, and re-built and re-tested many times, before being put into production. So, the fact that within 4 to 5 years these companies all brought out new models, often replacing a full-size model that was only 2 or 3 years old, speaks volumes as to the disruption the OMs caused.
We have Kodak and Leitz (maker of the Leica) partially to thank for the shrinking of 35mm SLR (single lens reflex) cameras in the 1970s. If it weren't for the obstinacy of the former and the inspiration of the seminal IIIf & M3 models produced by the latter, we may never have seen one of the most influential SLRs in history, whose consequence is still affecting the camera industry. Let's take a trip back to the late 1960s and the birth of the Revolution...you know it's gonna be...all right...all right...all right...
Suffers from an 18-year and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots. He even mixes in some digital. Definitely a sick man.
