Just published in DAP is an update to my review of the 37.5 megapixel Leica S2 digital camera.
Even if you shoot another brand, you might find the new moiré page and diffraction page useful.
I’ve also added a new autofocus / manual focus critical comparison with generous actual pixels crops from f/2.8 through f/22 showing that if you want top results out of the S2, you had better think of it as a manual focus camera, because AF lost 2 stops of sharpness in my comparison. This actually holds true for other brands too (even Nikon or Canon), though they often work quite accurately with AF.
And I’ve also added a reader comments page.
Finally, I just upgraded the S2 firmware from 1.0.0.13 to 1.0.0.16, and I’ll be checking what issues have been addressed, or not.
I am very impressed with the imaging quality of the Leica 70mm f/2.5 Summarit-S ASPH. If it can be focused accurately, it ranks among the best lenses I’ve ever used for that range. It is especially impressive for its corner-to-corner sharpness even at f/2.8, and easily beats most every lens for the 35mm format— quite an accomplishment. It has a trace of field curvature, but it’s very low for this focal length and speed lens. And while contrast is just a touch low at f/2.8, sharpness is outstanding, and it seems to peak at f/4.
