While praying for the RF 50 f1.4 which I'm sure will NEVER EVER arrive
I ended up finding a very good price on Amazon for a brand new (I couldn't remember last time I bought a lens that wasn't already used!) Sigma Art 40 f1.4 which seems to have stellar optics, so I bought it; I could even pay it in 5 months with no extra fees tnx to Amazon offers, so it was a no brainer. Should be arriving tomorrow.
To make some space for it, I placed on eBay both the RF 35 and the 50 Art, they should exactly pay for the new 40mm, and if I'm lucky I can even get back 50/100€ more then what the 40mm cost. I bought an used RF 50 for 115€ to be the go-to vacation/personal combo with the RP.
Then, I already gave away the RF 85 STM, wasn't satisfied with AF speed and flare when shooting into the light, but now I have a big gap from the new 40mm to the 135 Art; so I'm going to sell it, too, to buy either the 85 Art or the 105 Art, depending on prices I'll find (85 it's easy to find, 105 not so much...but I want that, so I'll probably end up buying an 85 now, and then reselling it as soon as I get my hands on a 105).
What's the take on it? For me the best lenses, price/performance wise, for R cameras are still adapted EF lenses; I had 3 RF's (16, 35 and 85), ended up selling all three of them (16 and 85 sucked, 35 was good but too close with the new 40 to keep them both) just to buy the fourth which is the cheapest of them all.
While Canon camera offering is pretty good, their lens offering is unsatisfying in the low end, and unreachable in the top end; the average professional today has no real motivation to buy into the RF line-up, it's safer to buy into used EF gear, where there are focals and brightness much more interesting then the new RF's, and now you find very great prices both on used stuff and on shelf leftovers. What a shame.
