A lens captures more than what we can imagine and for a good quality image, it is important to invest in the high quality lens. If you already own a decent body, invest in great optics for higher resolution and clarity of content.
The biggest trouble lies in deciding which DSLR to buy for your various photography needs. From Nikkon to Cannon, Sigma, Tamron etc gives you a perfect photograph but what matters is the quality of lens and focus. Here’s a glimpse of using right lenses for different photography types:
Portrait: In Portrait shots, there is a need of sharp focus and mid range focal lengths with large apertures.. A focal length starting from 50mm to 150mm are ideal for portrait photography.
You can either buy fixed focal length lenses such as 50mm, 85mm, 135mm or zoom lenses such as 24mm-70mm, 24mm-105mm, 18mm, 105mm, and 70mm – 200mm. Fixed focal length lenses gives an edge thereby resulting in sharp images with pleasing bokehs, however, zoom lenses provide more flexibility and enables you to take better pictures.
Landscape: The most popular yet tricky photography because it requires you to capture panorama, therefore a wide angle lens suits this. A focal length starting from 8mm to anywhere around 35mm would be ideal for landscape photography.
You can consider lenses having 8mm-15mm, 10mm-22mm, 16mm-35mm, 17mm-40mm focal lengths. For landscape photography, it is also important to have different filters such as UV, Polarizing, Neutral Density, and Graduated Neutral Density to add effect at optical level. Fish-Eye lens are quite a rage for shooting creative landscape images, but they cannot be used always.
Wedding: The most difficult yet engaging photography where it is important to capture different moods, emotions, occasions, food, couture and much more. The lighting levels drop down as weddings usually take place after sunset or in closed halls. Apart from using studio lighting and flash, it is very important to choose best suited lens. A 70mm-200mm with F/2.8 is considered to be one of the best wedding lenses. A large aperture helps in low light photography and large aperture combines with long focal length to give outstanding bokeh effects. You can capture natural expression using this lens.
However, a second lens such as 24mm – 70mm will help you capture a group of people in one frame.
Wildlife: This is the actual exam for any lens. You need the largest possible focal length (as the animal can be far), largest possible aperture (as the lighting condition can vary randomly in forest and fast shutter speeds can be frequent requirement), best image stabilizers (so that you can take stable handheld shots) and lightest possible weight (so that you can hand hold lens for longer duration). Optimization is the key to have beautiful wildlife shots. Any lens from 300mm and above works perfectly for wild life photography. Image stabilization secures the second most important factor for Wildlife Photography.
You can either buy prime lenses (300mm, 400mm, 500mm, and 600mm) or zoom lenses (100mm-400mm, 80mm-400mm, 150mm-500mm). The zoom lenses provide enough flexibility to capture wide shots, but the image quality from a prime lens is unparalleled. Moreover, prime lens have larger apertures than zoom lens but they are quite expensive.
Sports: Pre-requisite for Sports Photography is similar to that of Wildlife Photography since the conditions are similar. However, there is a benefit that you may fix a position so can use a tripod. The requirement of lens is same as that of Wildlife.
Night/Low Light: The basic need for night or low light photography is larger aperture. Any lens with aperture equal to or larger than f/2.8 would be considered good for this purpose. The best and cheapest lens for this purpose is 50mm f/1.8.
Fashion: Fashion Photography needs professional grade lenses as the images may be used for commercial purposes. Therefore, a standard zoom lens with focal length ranging from 18mm to 200mm (preferably from 50mm to 150mm) and large aperture would be a perfect match. Some of the best options could be 24mm-70mm, 24mm-105mm and 70mm-200mm. A lens with image stabilizer is indeed a great idea. A prime lens may not be very helpful for shooting the ramp walk since shooting at a varying distance without enough movement is a big task. But, they can be surely given preference for shooting portraits.
Architecture: The main requirement for Architecture Photography is straight lines. Shooting from a reasonably good distance using a lens having focal length in the range of 18mm to 200mm will do a good job. Usage of special purpose lens called tilt and shift lens will be equally great. Fish-eye lens will help in shooting creative architecture images.
