Thanks for the kind words, I love this spot for sure.
Interesting question. I just printed it at 20 x 30 from LR @ 300 ppi and it looked very good. I think I could get it to 24 x 36 pretty easily, and with a little interpolation help 30 x 45.
The 16 1.4 is a wonderful lens, not only very sharp but it has an amazing close focus range, of around 8" or something I can't remember for sure, but you can really get close. I love to use it as a macro lens close to wide open as the Bokeh is very nice.
I use it along with the 56 1.2 and really prefer both of them. I stopped using the 16-55, to big and just not sharp enough alot of the time, might just be my lens. The 16 1.4, 23 2.0 and 56 1.2 are my main carry lenses but I still use the 10-24 when I need wide wide.
