For quality, not compatibility.I used to have the older 50mm 1.8. several years ago now and out of touch with it all.
So, it has to be STM?
For quality, not compatibility.
As mentioned by Alan, the only issue with a Nifty on apsc is the very tight field of view for general shooting. It's more of a traditional/typical portrait focal length.
Personally, I'd be thinking more around the 28mm or 35mm range for a more versatile prime lens especially on apsc.
It's up to the OP/personal preference but I always wince a bit when people talk about "nifty 50's" on crop cameras as IMO on crop cameras they become completely different things. I have used a 50mm a lot on MFT giving an equivalent FoV of 100mm (MTF is x2 crop) but I did understand that it was no longer a "nifty 50" but the 25mm I also have is.
Good luck choosing Raincloud.
25mm is 2.8 though?
To add to the above the only canon 50mm EF to buy is the STM.
The best option is the Sigma Art 50mm
But I hated 50mm on APSC, not long enough for a decent portrait and too narrow for anything else.
There’s a Sigma 30mm 1.4 that used to be prolific for serious crop shooters back in the day. And that’d be my recommendation.
