jplomley Posted December 29, 2019 Share #61  Posted December 29, 2019 (edited) Advertisement (gone after registration) It is an amazing lens, but due to extreme field curvature between 16 - 19 mm it is necessary to focus stack for landscape applications, usually with three separate images in order to obtain sharpness in the corners. I also note a right edge bias of lesser sharpness, almost a smearing effect. As someone else mentioned, it is tricky to tame this lens, but once figured out and the workflows created to optimize its potential, it is very versatile.  SL + 16-35 SVE at 16 mm; 3 image composite (focus extreme corners manually, mid-focus and far focus by AF, all at f/8.0 with Leica 82mm polarizer) Welcome, dear visitor!

Possibly a slightly decenteted lens element somewhere? Others can/should test (including myself...), but I would be more than surprised if this is a general charateristics of the lens. Although very sharp and very resistant to flaring, the lens show quite some aberration/coma towards the edges/corners wide open, so an astrophoto lens it is - unfortunately - not. 1 Link to post Share on other sites More sharing options...

Others can/should test (including myself...), but I would be more than surprised if this is a general charateristics of the lens. My thoughts exactly. A quick test against a friends 16-35 demonstrated better edge and corner performance between 16 mm and 19 mm with his copy.  He is waiting for his SL2 and then we shall do more definitive tests off a tripod with the lens stopped down to 5.6, 8.0 and 11. I'll use these data files as evidence their is lens variation. Whether Leica deems the variation within acceptable tolerance is another question. 1 Link to post Share on other sites More sharing options...

jplomley Posted December 30, 2019 Share #66  Posted December 30, 2019 The lens has also been fantastic for documenting some of rural America, currently focussing on the back-roads of NH and VT Welcome, dear visitor!

Just curious - which software do you use for focus stacking? Link to post Share on other sites More sharing options...
jplomley Posted December 31, 2019 Share #70  Posted December 31, 2019 I’m currently just using Photoshop. Might try Helicon in the new year, but I’ve yet to find an image PS cannot handle. 1 Link to post Share on other sites More sharing options...
