How large a print can you make from an M9 file?

Well, the largest I’ve printed for clients is 36 x 24 inches:

Even at this large a size, the detail from the M9 and the 50mm Summilux combo used to create the image above is impressive.

However, yesterday I tried doing this for the first time with two other lenses:  the 24mm Summilux (f/1.4) and and the 50mm Noctilux (f/0.95).  Truth be told, I wasn’t expecting anything near as good as what I get from the technically brilliant 50 Summilux ASPH.

We’ll I’m happy to report that I was wrong.  They not only did well, they did exceptionally well — I was astounded to see how much detail the 24 Summilux and 50 Noctilux produce at their widest apertures.

But in the age of phone and tablet image viewing, most people will never encounter an actual print, let alone a 36 x 24 print.  So what does 36 x 24 actually look like?  I thought I’d show you with a little demonstration:
