Typically a prime lens will have only ring (manual focus), though some will have an aperture ring. The RF 100mm macro is an unusual prime lens due to having three separate rings on it.
I’ve gotten many, many questions on my YouTube channel of people afraid that something is wrong with their lens because of this behavior. The physical aperture does not (the physical opening will still be 1:2.8), but less light passes through that physical aperture, meaning that you’ll need something like 2 stops of additional light if you are shooting at macro levels relative to what you will need at a portrait distance. The maximum aperture here is F2.8, though it is important to recognize with all macro lenses that as you approach 1:1 macro (and, in this case, beyond), the laws of physics dictate that the effective aperture changes.
The diameter is only slightly larger (81.5mm, leaving the same standard of 67mm for the filter thread), but the weight is up to 730g vs 625g for the EF version. That’s a 25mm growth over the EF version, and makes it roughly 60mm longer than the RF 85mm F2 Macro. The new lens is 148mm, which is about as long as the Tamron 70-180mm F2.8 zoom for Sony. The size difference is pretty significant, though. I was unsurprised to find that the size of the new RF100M had grown relative to the EF version, as that seems to be par for the course. *The tests and the photos shown in this review have been taken on my 45 MP Canon EOS R5. As always, this is a completely independent review. They are my personal source for my gear and have been great to work with. Thanks to Camera Canada for loaning me this lens for review. If you use a lens like this the way that it should (for general purpose, portraits, etc… along with macro), I suspect the correct answer for many the answer will be yes, but you can find my more detailed thoughts by watching my long format definitive or standard video review below…or just keep reading!įollow Me Patreon | My Newsletter | Instagram | Facebook | DA Merchandise | Flickr | 500px Here’s the difference between a 1.0x magnification and a 1.4x magnification: Does that make a difference? It definitely does.
#CANON MACRO 100MM 2.8 USM UPGRADE#
The the first and most obvious upgrade is that this is not just a 1:1 macro lens anymore, but now we have the ability to go as high as 1.4x magnification.
The new RF100M (as I’ll call it for brevity) takes a lot of the things that made the EF lens special and ups the ante in several ways. This is an updated version of the lens designed specifically for Canon’s new RF mount (for the EOS R mirrorless system). The lens that may finally bump it out of my kit may have arrived, however, and that is in the form of the excellent new Canon RF 100mm F2.8L Macro IS USM. I’ve changed cameras a number of times, and even though I don’t even own a camera with a native EF mount any longer, the EF 100L Macro has stayed with me because it just keeps working so well. I have had dozens of lenses come and go since I purchased the 100L Macro back more than a decade ago. The Canon EF 100mm F2.8L Macro IS USM holds a very unique place in my personal lens kit it has lasted longer than any other lens.
