Canon RF100mm F2.8 L Macro is USM Lens, Medium Telephoto Lens, Macro Lens, Compatible with EOS R Series Mirrorless Cameras, Black

Almost all of my macro shots are taken hand held, so I really like the IS of this lens. Combine that with the IBIS of the R5 and R6 and you get a winning combination. I've tried the Spherical Aberration (SA) ring, and it works ok, but prefer to do that in post, if need be, so I have it locked on "0". Once you get the hang of it, it could save you a bit of editing in post if you like to mess with that, so I think it is a nice feature. I'm just not big on doing a lot of post editing, particularly messing with bokeh. I like the control ring of the new RF lenses and have it programmed so I can select focus points. It focuses quickly and I don't think it's entirely the cameras because I have the EF 100mm f/2.8 L IS USM Macro and ring adapter, so Canon has improved on the USM. IQ is similar to the EF version, but I have to give the edge to the RF (I'm a pixel peeper), I have taken enough shots with both the EF and RF 100mm f/2.8 L IS USM glass on the R5 to make a fair comparison. As you may know, all lenses have a "sweet spot". Although it has very good IQ wide open (f/2.8), but take it up a few stops, and IQ is amazing. I've found f/8+/- to f/16 to be a good range, although I haven't needed to take it higher than f/16 to get my shots. The wasp face was taken at f/16, 1/500th. The RF 100mm f/2.8 L IS USM Macro is a nice improvement of the EF version, IMO, and is a must have if you like to shoot macro, even occasionally, on your new R series camera. Yes, it is a bit expensive, but worth every penny. It's really hard to tell from images posted here just how good they are, but I will post some anyway. The shots are cropped, maybe 50%, mainly because the subjects are so tiny and even at 1.4:1, they are small on the R5 sensor. The flower with the yellow disk is smaller than a dime and is a 40 shot "focus stack" taken using the EOS R6 on a tripod. The other flowers are 1/4"+/-. The wasps are 1/2", if that. Except for the "focus stacked" image, the rest are "hand held" and I used high ISO settings so I could freeze action and to keep my aperture in the "sweet spot". The wind was blowing the flowers and the insects were constantly moving.

Beautiful lens.

主に野草や花の接写に使用してます。 イルミネーションも良いですよ。

Increíble, fabuloso lente. Todo llegó en excelente estado. Lo vale para fotografía dental.

Very nice lens. I purchased this to replace my EF 100mm lens and couldn't be happier. Fast focus, accurate, nice optics. Excellent for macro photography and I think has a 1.4x magnification factor, compared to the EF at 1.0
