I've been using the rf100 for the last 18months, sensational lens. Macro is brilliant and also makes a good portrait lens also. One of my favourite lenses ever 👍👍

I'm going to Panama in March. I will take my RF 100mm f/2.8 IS macro thank to you! Well done.

Entretenido y buen review hace dias que estoy pensando en comprar este lente, un saludo y gracias.

In the UK that lens is £1449!!! I can get it grey for £799. I think for macro work as you say a used EF100mm for a fraction of the price fitted on the R7 might be good (100mmx1.6 crop) so similar to your Sigma 150mm f2.8 with a FF. The focus stacking is great even works sometimes handheld. I decided to hang on a little longer to Canon recently got a R7 as I still have awesome Canon lenses. If the R5 II is just a minimal update ie no stacked sensor I'm think Nikon. For macro I'm tempted to go OM-1 with it's stacked sensor they come bundled with a good lens quite cheap recently. I'm seeing some great work with that camera and there is a new OM-1 II update about to be announced. Great channel deserve more subs.

Some absolutely stunning images! Would be great to see your handheld and tripod workflow (the rf100 probably has gone back to Canon now though). Canon absolutely need a EF 180 macro successor and the MP. I myself are more than happy with the EF100L macro. Enjoy Costa Rica

Спасибо. Сейчас посмотрю, как раз думал о таком. )

I have a similar setup R5 and R10, the latter with the 100-400. I love how light, cheap and sharp that combo is. I use it with a pair of Godox flashes with great results. One question, when bought the R10 i thought it would have the pre-capture feature like the R7 and R6II, but I can't find it. I should have done my homework better. Still like the camera though. We just came back from Panama and the birding was incredible. Thanks to fantastic local guides.

they could of made the lens cheaper and dumped the gimmick SA feature that nobody will ever use

For me, the 100-500 is good enough for butterflies and dragonflies that I couldn't justify buying this lens. But, it looks to be pretty great a a dedicated macro. I bought the 35mm RF macro and hardly use it, because you'd need to get extremely close to the insects. That lens is actually pretty good for landscape!

Fabian the macro that I use is the Sigma 180 F 3.5 it's over 20 years old and with the adapter on the R7 it is a great combination for doing Butterflies and also caterpillars small insects like ants like what you're doing and especially on frogs .

Very valuable info. BTW, are there any problems with Sigma 150 on Canon R5/R10 ?

You can manually focus with the lens, but not while actively engaging AI Servo AF. With the camera in AI Servo, you can manually focus if you do not have focus engaged by shutter half press or BBF. Manual focus is available full time while in one shot. I assume that you were trying to manually focus while focus was engaged with the shutter button or BB. That said, I find the description of your setup problematic. You have AF on the shutter button for spot and you BB for animal eye. Why don’t you move to a dual BBF setup and remove AF from the shutter? Put the spot on the AF-ON and the animal eye detection on the * button. That way you will have access to either manually focusing or focusing by changing the lens to distance subject without the problem of engaging AF with the shutter button or worrying about the AF/MF switch.

Great lens, I use it, however the SA function was such a marketing gimmick from Canon...
