Re: What is the impact on using EF mount adapters on the M and RP?

Hi, Thanks for that, nice to here from someone with lots of cameras!
The more I look into things perhaps staying with a crop sensor is the way to stay!
Either m6ii or new M5ii when available.
Cheers
It might be controversial - but I use a speedbooster.
You get the best of both worlds and it lets you carry less lenses.
Use with the M adaptor to get aps-c crop when you need reach - such as getting a 300mm lens to 480mm.
Speedboost when you need wide or more speed. Mount my 17-40mm f4 Canon L and it becomes a 19-45mm lens at f2.8.
(The DOF doesn't change, but the exposure is 1 stop faster).
I use the Viltrox at the minute, which has some poor corner sharpness wide open, but I will buy the metabones once it gets to a decent price 2nd hand.
Reviews and some pixel peeping indicates there is practically no loss of sharpness on the MB speedbooster.
This will give me a small full frame camera with reach from 19mm all the way to 480mm (and I use a TC, so I get to 672mm) with 2 lenses.
I also carry a nifty fifty, which is practically full frame 50mm (56) on the booster, but now lets in f1.4 worth of light.
I find the M system with a Speedbooster gives access to a phenomenal ecosystem of using top grade Canon glass. Once the R system comes down in price as well, there's an upgrade path on to R as well, for the sake of a £50 adapter.
If you want thin and light as well, the Canon M kit lens (18-55) is a good enough boring kit lens and there is a decent 300mm small zoom (but that's not enough for me )
