![]() ![]() After our adventures there is no doubt in our minds that the Canon RF 100mm macro is going to be a favorite among Canon mirrorless shooters. Fortunately for us, we have been able to dive with the Canon RF 100mm f/2.8 macro for the last couple of months in Southern California as well as the Sea of Cortez. The Canon RF 100mm macro is perfect for cameras like the Canon EOS R5, R6, R3, and R. ![]() While this lens shares many similarities with the original Canon EF 100mm macro lens, it is equipped with some notable new features - like 1.4X supermacro magnification, quicker and more accurate AF acquisition, and a spherical aberration (SA) control ring. Even here though, sharpness remains very impressive and the Laowa is able to capture very fine detail when using its narrowest aperture in close-range shooting.The Canon RF 100mm f/2.8 L IS USM macro lens is the best underwater macro lens option for the new full-frame mirrorless RF lens mount. Sharpness holds up very well right down to f/16 and only really drops off at f/22. Naturally, due to the minimal depth of field in extreme close-up shooting, sharpness at the narrow end of the aperture range is a more important consideration for macro lenses. Sharpness is superb right across the image frame from corner to corner, even when shooting wide-open. This enables the use of sensor-shift stabilization. With the Nikon Z 6 and Z 7, for example, you can enter the lens information into the ‘Non-CPU lens data’ section of the camera setup menu. This is lacking in the Laowa lens but you can generally take advantage of in-body image stabilization if featured in the host camera. Some macro lenses have conventional or even ‘hybrid’ image stabilizers that can correct for x-y shift as well as the more usual angular vibration. Getting sharp shots can be a real challenge with any macro lens, due to the need for very precise focusing and the ever present risk of camera-shake. These are useful for general shooting but completely superfluous for extreme close-ups, where depth of field shrinks to just a few millimetres, even when using the narrowest available aperture of f/22.Įven at f/16 with diffraction creeping in, the lens is able to capture incredible detail and texture at 2.0x magnification. Depth of field markers are also on hand for apertures of f/2.8, f/5.6, f/11 and f/22. Clear markings show the focus distance in feet and metres, as well as the magnification factor. ![]() Naturally, when using very narrow apertures, the optical viewfinder of an SLR would become very dark, but this isn’t a problem with mirrorless cameras.īuild quality feels pretty solid and robust, but the lens doesn’t feature weather-seals. The 13-blade diaphragm narrows in a continuous manner as you rotate the ring. The aperture ring operates similarly smoothly with barely perceptible click steps at each full f/stop. Most of this is dedicated to the close focus range between 0.25 and 0.5 metres, enabling very fine and precise adjustments when shooting close-ups. The focus ring itself has a rotational travel of just over a quarter of a turn in total. Despite the lack of electronics, focus peaking and enlarged preview are naturally still available in mirrorless cameras. Highly accurate focusing is a prerequisite for macro photography.

Weight: 650g (638g for Canon EF & Nikon F) Lens construction: 12 elements in 10 groupsĭiaphragm blades: 13 (9 in Canon EF, 7 in Nikon F)ĭimensions: 72x155mm (72x155mm for Canon EF & Nikon F) Mount: Canon RF, Nikon Z, Sony FE, Canon EF, Nikon F All of the mirrorless format lenses have 13 diaphragm blades, producing a very well-rounded aperture when stopping down. The DSLR-format lenses are physically a bit shorter and have a reduced diaphragm blade count of nine and seven, for Canon and Nikon mount respectively. But a more recent mirrorless version was produced for Sony FE-mount mirrorless cameras and is now also available for Canon R-series and Nikon Z-series bodies. The original was designed for full-frame DSLRs, and is available in Canon EF and Nikon F mount. There are two very similar versions of this lens. ![]()
