How slow is a SL1 compared to new mirrorless cameras?

I shoot a SL1. Im looking to jump to mirrorless, either a used a7rii, or new eos rp. I can adapt my lenses to either although the canon adapter is included with the rp, which is nice. I'll be buying new lenses as I can.

I keep reading that the Canon has faster AF, that the a7i had really slow af. The a7rii seems to have still slow af, but better than the a7i, or a7ii.

I don't have anything to compare this to though. Compared to something like a SL1, are all 3 going to be lighting fast?

I can only compare this to computers, something I'm an expert in. Is this like someone coming from a 10 year old celeron laptop with 2mb of ram, and moving into an i5/i7 (7th gen), with 8gb of ram? Are any of these cameras going to blow me away autofocus wise?

I can only assume the sl1 is slow, but i dont know if it's slow like an a7i (which i know is a way better camera), or if it's slow like it's in the stone age slow. I've googled endlessly looking for this, spent about 8 hours reading reviews. I've learned so much other stuff which has been great. But not this main question I want answered before dropping 2g.

Any help is appreciated. Thank you.

I'm sorry for the noobie question, I really did try to research this quite a bit.

Canon EOS SL1 is known as the Canon EOS 100D in the UK. I assume you mean Canon?

If you're a fan of Canon colour and the results you get at the moment then that may be a deciding factor.

Things you'll probably notice in the switch is a much higher number of focus points as well as a much wider coverage of the frame (rather than the focus points all being in the centre). There are other benefits, such as face (and eye detection) focus.

Have a look at the reviews on here, the focus speeds should be in the reviews.

Here are the AF speeds from the following cameras, however, it's worth noting that the cameras were tested when new, and firmware updates may have been released since then, which may have improved focus speeds:

Canon EOS 100D / SL1 : (First figure is using optical viewfinder, second is live-view using the rear screen)

You might want to go fondle and check out the EVFs before parting with any dosh, there is still a lot to be said for slightly larger mirrorslappers with OVFs

Bear in mind a Canon FL 24x36 does not have IBIS - and Sony and Nikon do.

A couple of thoughts on the OP and the comments above.

OP - why are you focused on the 'old' SL1 rather than the newer SL3? Do you see some advantage in the older model other than price? Or, the SL2?

Comments: With respect to the shutter speeds quoted, are you sure 'shutter response' means the same thing as AF speed? For DSLR's you can just click away and the mirror will swing as fast as you push the shutter release, but that doesn't mean focus can lock that fast such as in low light. Shooting conditions can have a great effect on AF speed.

I'd be careful with what you may assume.
