Hello

to be expected at this price point

My old Canon 50mm f/1.4 super sharp but not at f/1.4

it really shines from f/2.8 and is über-sharp at f/5.6, same as a very expensive prime

That’s actually what you pay for when you reach for the expensive primes.. they are tack sharp directly from full opened

still, at f/1.4, I managed to shoot my most beautiful and dreamy portraits at night with air ballons filled with fire in the background … that would have been impossible to shoot at f/1.8

Thanks for the reply. You lost me a bit here though. You said how your 50mm 1.4 was not super sharp at f1.4 but then later say (in bold) that at f1.4 you were able to shoot beautiful and dreamy portraits. Did you just mean you still got some great bokeh shots at 1.4 but they just weren't super sharp?

Yes, exactly

Getting a very sharp shoot is not always synonymous of a nice shoot.. important, but in low light, it's only part of the equation

Why you pay several times the price for an "L" prime over this "Nifty-Fifty" is just about that, getting a sharp shoot straight from the maximum aperture.

If you go to f/5.6 or f/8, the difference btw the 2 is minimal and does not matter

If you want sharp images at f/1.2 f/1.4 f/1.8 you need to go for the likes or Canon "L" or Sigma ART lenses

Take care and relax about your lens

Just know its normal use case and expected limitations... or upgrade it
