Unfortunately, the soft-focus effect was ruined by gross over-correction behind the focal plane, giving hideous bokeh which would put a mirror lens to shame! I dumped mine, unloved. I had a Tamron 70-150mm soft-focus zoom which introduced SA at the focal plane. Both were regarded as good sharp lenses.Ĭanon had an EF 135mm f/2.8 lens with a soft-focus control as well. With this control zeroed, the 135mm lens was VERY sharp. However, the effect did not require shooting wide open, increasing the flexibility - and potential for confusion! a portrait subject, somewhat as if a much longer or wider-aperture lens had been used. It was largely about bokeh - increasing (undercorrecting) SA behind the plane of focus was intended to improve the quality of bokeh behind e.g. Chromatic aberration was well controlled, no obvious fringeing being introduced in the process. Some was introduced AT the plane of focus in either case, giving a soft-focus effect which could be varied as the "defocus" control was variable. The "defocus" control introduced undercorrected SA selectively either behind or in front of the plane of focus depending which way it was turned (presumably overcorrecting it on the opposite side). I think there IS a precedent for this lens - the Nikon 135mm and 105mm f/2 DC (defocus control) lenses released years ago. I would recommend shooting from a tripod if you want such magnifications. With this magnification, the image stabilization isn’t that effective anymore. This way, the RF 100mm f/2.8L IS USM macro offers more possibilities for the macro photographer. With a minimum focus distance of 26 cm, you can reach a 1.4 times magnification, which is great. Buy Canon EF 100mm f/2.8L Macro IS USM Lens in Sri Lanka featuring EF-Mount Lens/Full-Frame Format, Aperture Range: f/2.8 to f/32, One Ultra-Low Dispersion. Using the RF 100mm f/2.8L IS USM for MacroĪlthough this lens can be perfect for portraits, just like any other 100mm lens, it is mainly for shooting small objects. There is a possibility to acquire a tripod collar, but it’s not included. When a lower quality tripod head is used, I can imagine it will be difficult to hold it in position. When fitted on a tripod, the center of gravity is placed well in front of the mount. It’s not too heavy and it balances reasonably well on a Canon EOS R5. The weight and size of the lens hold no surprises. A small switch on the lens locks this ring in the neutral position, preventing movement. This ring can rotate up and down in a negative and positive direction.
Finally, the lens offers a ring that controls the Spherical Aberration, which is basically a way to control the bokeh when using a shallow depth of field. Canon RF 100mm is the worlds first AF macro lens with an incredible 1.4x magnification (1.4:1) capability delivering sharp, high contrast images across the.
