Leica 90mm f/2 APO-Summicron-SL Aperture Series: Painted Rock (Focus Stacked, Panasonic S1R Multi-Shot High-Res Mode)

Get L-Mount lenses at B&H Photo.Leica 90mm f/2 APO-Summicron-SL about $5150

This aperture series looks at imaging performance from f/2 through f/8 on the Panasonic S1R in Multi-Shot High-Res mode.

I had shot this scene two ways: one series focused on the eye and the other on the leading edge of the rock, doing so because I knew that the focus instability problem would damage sharpness across the series; I thought that one series might be usable.

In total, neither series was satisfactory for all apertures. Later, I decided to make lemonade out of two lemon series: for each aperture, I used focus stacking, tedious but well worth the results—the series speaks for itself as stunningly high in detail, even at f/2.

In diglloyd L-Mount Mirrorless:

Leica 90mm f/2 APO-Summicron-SL Aperture Series: Painted Rock

Images at up to 125 megapixels plus crops. The imaging quality is spectacular.

What an incredible waste of effort to shoot at 24 megapixels or even 47 megapixels—check out the stunning quality of the 47MP image as downsampled from the 187MP capture with its total freedom from all digital artifacts and near-zero noise. That kind of image qualitiy cannot even be approached with the best 35mm cameras today, it’s in a league by itself.
