Almost everyone who owns a camera with interchangeable lens is faced with the major problem of selecting the right lenses to buy, and actually deciding which one to use at the end. There are however some rules or tips to follow depending on your personal style and what you have already. To help you make this choice and also how best to actually use them, below are the following tips;
Normal lenses: Nowadays, many photographers especially those with 35mm usually go for a very short zoom instead of the normal 50mm; however both have their various virtues as well. For those that need a fast and general purpose lens probably f/1.4-f/3 range for just some light work, then you obviously need but a 50mm.
It is peculiar in that it is first of all short zoom, not expensive, produce very sharp images and finally it is capable of providing brighter pictures. However, the negative aspect of it is that does not zoom, you have to do that by moving closer to the object.
For those with shorter zooms, they offer the possibility of framing flexibility, usually not more than a 50mm lens. The less expensive ones are those with 35-70mm f/3.5-7.4 and in most cases, the smallest, 29-75mm f/3.5-4.7 are very useful in interior shooting and cramped quarters due to the fact that they can get down to 25mm. For those who are either shooting a portrait, sports, or nature at a very close range, then what you need is a compact 35-109mm zoom.
The positive effect here is that it provides intermediate focal lengths so that there is absolutely no need to switch lenses, while the negative part is that it limits low light shooting and focusing accuracy with manual focus that often affects the viewing brightness. Furthermore, the zoom might seem to be much larger, heavier and even more expensive than 50mm lenses.
Wide-angle lenses: They might range from 25mm to 35mm. Like most normal lenses, you can use those with single-focus-length lenses with relatively wide aperture and a moderate-aperture zooms which is capable of providing a superior framing flexibility. To actually see the positives as well as the negatives on the types, then you have to find it below.
There are many wide zooms that can take in normal as well as wide-angle focal lengths, which is an extension, can be considered as an advantage. Most of them are neither as heavier than a 50mm, even though 25-50mm or 23-37mm might not be very attractive or impressive, but it is actually just the zoom ratio that matters.
For those that really need a fast wide-angle probably 37mm f/1.5 or 25mm f/5, then you go for the available light or shooting handheld lens with the slow film to stick to a single focal length.
Ultra wide-angle lenses: These types of the lens have focal lengths of 22mm just below the 35mm format. Thus, allowing extreme angular coverage of 90 degrees and even more. Ultra wide-angle lens due to the fact that they have low image magnification, they provide great depth of images in the field, thereby making the images to be sharper at even slower speed speeds.
Also, they are good in providing excellent images in tight interior spaces and capturing vistas often good in street photography and other intimate photojournalism. On the other hand, although they are actually good and useful for dramatic or comic effects, its portraiture isn’t that good. To avoid this, do not place subject closer to the edges of the frame.
Medium telephoto lenses: It is often called portrait lenses since it is good in providing fine portrait images that minimize the perception of distortion, thus provides a convenient working distance during shooting period. Most tele zoom lens usually works well in this range. But they are much heavier and slower than single focal length lenses. One of their features is that they make room for discreet photography and very good quality images.
Long tele lenses: It is often known that any lens that is over 135mm for 35mm photography is a long telephoto. They are made with reasonable size, weight, and price with wide range of uses. They are used in sports, nature, portraits and even people. Negatively, they produce moderate and variable aperture.
