Zoom lenses do have some disadvantages compared to prime lenses that you should take into consideration.Ī zoom lens is usually not as sharp as prime lenses. This is great if you are on the road and you plan to take different types of photos. You can adjust the focal length to the scene in front of you without the fuss of changing a lens.Īnother great advantage of a zoom lens is that you won’t need to carry several prime lenses so that you can travel lighter. This is great for photojournalism or event photography. The main advantage of a zoom lens is that you can change the angle of view quickly and without changing lenses. What Are the Advantages of a Zoom Lens vs Prime Lens?Ī zoom lens presents certain advantages and disadvantages in comparison to prime lenses (a lens with a fixed focal length). This photo and the photo below were both taken from the same spot using the same 18-140mm lens. In other words, you can change the angle of view and make it narrower (zoom in) or wider (zoom out). Zoom lenses allow you to adjust the focal length of the lens within a specific range. A smaller part of the scene will be in the frame. Lenses with longer focal lengths will narrow our angle of view. We will see a broader frame in the camera than with our eyes. Shorter focal lengths will widen our angle of view. If we take a photo with a 50mm lens, the scene will look pretty much as we see it without the camera. This might sound a bit confusing, so let me show you some examples.Ī 50mm focal length (in a full frame camera) corresponds approximately to the angle of view of the human eye. So it doesn’t correspond with how much of the scene the camera will be able to capture. This measure is just the distance between the center of the lens and the sensor. It is measured in millimetres (mm).įocal lengths usually range between 8mm to more than 300 mm.ĭoes it mean that the camera will capture just these distances? Luckily it doesn’t work like that because these are tiny distances! The focal length determines the angle of view of the camera, meaning how much of the scene you capture. To start at the beginning, we need to understand what the focal length in photography is. Both offer similar light transmission of just over four TStops, and like the full-frame version, minimal distortion, which is particularly well-controlled between 16 and 28mm on both lenses.A zoom lens is a lens that covers a range of focal lengths. Measurement: Nikon version takes the spoilsĪchieving an overall DxOMark score of 17 points tested on the Nikon D5300, and 13 points tested on the Canon 7D Mark II, the Nikon version is marginally ahead. There’s also a built-in SD-M autofocus motor and a GMR magnetic precision sensor promising quick and quiet autofocus on all Nikon / Canon APS-C bodies. Top-end features such as the weatherproofing seals and fixed fast aperture remain, as well as the “One-Touch Focus Clutch” mechanism for switching between AF and MF. Equivalent to roughly 18–42mm on Nikon, and a slightly longer 19-45mm on Canon APS-C cameras, it doesn’t quite offer the same field of view as the full-frame version, but it’s not far off. Tokina 12-28mm f/4 PRO DX: Tokina’s crop sensor equivalentįor crop sensor shooters, the DX/EF-S format Tokina 12-28mm f/4 PRO DX is the equivalent wide-angle zoom for Nikon and Canon APS-C. Where the EF 16-35mm f/2.8L does excel is transmission, where its extra stop of light will help bolster autofocus performance, particularly for press or event photographers needing snappy autofocus in low-light conditions. The best bit, however, is that at just $449, it’s significantly cheaper than many of the own-brand alternatives. It also employs Tokina’s “One-Touch Focus Clutch” mechanism to use the focus ring to switch between auto and manual focus. The fixed f/4 aperture is respectable for shooting in low-light environments and helps keep the size and weight of this wide-angle zoom down compared to larger-aperture alternatives. Tokina 17-35mm f/4 PRO FX: Water resistant and lightweightĪ full- frame 35mm option for both Canon and Nikon lens mounts, the $449 Tokina 17-35mm f/4 PRO FX is water-resistant (not waterproof) for pros working in challenging environments. We’re delighted to bring you an in-depth analysis of all the lens metrics for these lenses in our comprehensive review. Chief among these is the 35mm-format Tokina 17-35mm f/4 and the APS-C format Tokina 12-28mm f/4, both of which have been achieving some interesting results in our industry standard lab tests. There are some attractive options available, though, with third-party manufacturers such as Tokina offering a line of well-priced wide-angle zoom lenses in Nikon DX and FX, as well as Canon EF and EF-S formats. As ever, there’s a range of own-brand and third-party options to consider when investing in new glass, making it a bit of minefield to choose between them.
