12/1/2023 0 Comments Canon macro 100mm 2.8 usmWhen using a lens that extends beyond the lens barrel during focusing it is not always easy to be aware how much the lens has gone forward. There is also another major advantage of a non-protruding lens element. This is a great thing when you’re using filters or polarizers as turning the focusing ring would not rotate the filters mounted at the front end of the lens. The lens focuses internally and the barrel does not even rotate. Unlike the MicroMotor type USM they are quicker when focusing and also silent making them less intimidating.Īnother good thing about the EF 100 mm f/2.8L IS USM is that when focusing the front elements of the lens does not push forward. It is a reassuring feeling in these conditions if your lens is weather sealed to go with a weather sealed body.Ĭanon’s L series lenses feature RingType USM (UltraSonic Motor). Macro photography is often practiced outdoors, in the woods or in the middle of nature. The lens is weather sealed making it an ideal companion to have when shooting outdoors. Pick the lens up in hand and the feeling is reassuring. Engineered plastics gives a similar quality build but they are comparatively lighter. The rest of the body is made with “engineered plastic”. The focusing ring, the lens mount and the plates carrying the numbers and details are made with aluminum. The EF 100 mm f/2.8L IS USM is not built entirely with aluminum. They are all weather types and can withstand water (some lenses may need an additional UV filter to complete the weather sealing, so if you’re unsure whether your lens is weather sealed, don’t expose it to water). Normally Canon’s L series lenses are very tough. The Canon EF 100 mm f/2.8L IS USM is a great lens for serious Macro photography enthusiasts. Normally a 1:1 magnification is necessary to make a great quality macro photograph but higher ratios are also possible and can capture incredible amount of details of objects that are normally impossible to be seen by the naked eye.Ĭanon’s line of L series Macro lenses are incredibly sharp and offer a photographer with options to shoot very small subjects from a close focusing distance. 1:1 magnification denotes that the size of the subject on the sensor (and thus on the final image) is the exact same as that of its size in real life. A 1:1 magnification ratio is normally used to shoot very small subjects. Macro photography is all about shooting images of subjects which are very small and then filling the entire frame with them. First is the ability to magnify the image to a minimum ratio of 1:1 and the second is the ability to focus without protruding the lens elements outside the barrel. Two things are extremely important when it comes to choosing macro lenses. For the ease of understanding, however, we shall be referring these close-up lenses as Macro in our discussion. While Canon refers their lenses as Macro, Nikon prefers to call them Micro. For some unknown reasons two of the major lens manufacturers refer to their range of extreme close-up photography lenses with two different names. It is a segment of photography that deals with shooting pictures of small subjects at a size of 1:1 ratio or larger magnification and in the process capturing incredible details which are normally impossible to notice. Macro lenses can open a completely new dimension to your photography. Purchase options: Amazon | Adorama | B&H.Model name: Canon EF 100mm f/2.8 L IS USM Macro Lens.
