For what’s worth I have had this lens a few days and have been able to take thousands of pics with charts, people, basketball games, and scenery. I used an r62 and an r5. I have owned the rf50 f1.8 and 1.2L and borrowed the ef50L.
This lens is much better than i was expecting and i find pleasure using it. It is soft on the edges and reasonably sharp in most of the center at 1.2, to 1.8. At 1.8 the edges sharpen up and are very nice at 2.8. From 2.8 through 11 the lens is nicely sharp across the entire frame. At 16 it is still nicely sharp albeit a small amount of diffraction is setting. (Both the 50 1.2lL and the 70-200 2.8L i would classify as super sharp across the frame at all apertures and the difference is noticeable)
The autofocus and bokeh are normally pretty good. In fact the autofocus is to me quieter and less chunky than the rf501.2L. It is different from the other non L 24, 35, 50 and more like the 50L although not as fast. Has that recessed, clunky movement without the clunk of the Rf50L.
Where the 45 is downgraded is chromatic aberation with busy or shiny backgrounds and on occasions nervous bokeh. But in my first so called normal shots i never saw any CA. It wasnt until i intentional tried to get it by photographing jewelry and it was very noticeable. Also there is zero apparent weather sealing, but we knew that. The 45 is light and well balanced and has been just a joy to use. I have just been using jpegs with all the corrections. They are quite good right out of the camera .
The raw files processed through DPP are just so slow that i have to wait for adobe to get their profile up.
In summary i kind of liken the 45 to the 50L as the rf 100-400 is to the 100-500. Both surprised me with their weight, price, and image quality. Are they L lens quality? Absolutely not. But they are way better than i thought they would be and love using them at times when i don’t want that extra weight …..i.e. travel photography. Very similar results on the R5 as well.
For what you get at this price point it is quite a competent lens. I’m very pleased that canon engineered this lens and made it affordable for those who might want to try it. I hope they keep it up. Also I think canon has done a good job at accurately describing this lens. But i do love my L’s as they are still definitely a step above and beyond, but it comes at a premium price and usually a premium weight too!
Edit: attached files are 1.2 (279), 1.4 (280), 1.8 (281), 2 (282), 2.8 (283), 4 (284), 5.6 (285), 8 (286), 11 (287), and 16 (288). All at minimum focus distance and all straight out of the camera jpegs at 100 ISO. Canon R6II. Kind of in the reverse order I wanted. Oh well.....
