when light is plentiful, to obtain the sharpest portrait image when the subject is centered in the frame, does shooting at 5.6 yield any benefit then shooting at 1.4 with m lenses?

 

i am used to stopping down 2-3 stops to gain peak lens performance but wasnt sure if that still holds true with modern m lens like the 50mm asph lux.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

Yes. And not only because of the increased depth of field.

I like to think outside the box and suggest radical solutions...... you could try taking a portrait of someone at 1.4 and then at 5.6 and make your own mind up!

The Summilux 50/1.4 asph is probably the sharpest 50 at f/1.4 but it is even sharper at f/5.6. See the MTF charts page 3 of the technical data below.

most Leica lens will have peak performance at around f4-5.6, but the difference is hardly there since it's a Leica glass. on other brand, u may see dramatic increased performance, but not Leica's. what should concern you though is the mentioned depth of field. it all depends on what kind of portrait you do
