Leica 28mm f/1.4 Summilux-M ASPH: Analysis/Example of SLOCA (Secondary Longitudinal Chromatic Aberration)

Get Leica 28mm f/1.4 Summilux-M ASPH at B&H Photo.

There has been an unfounded amount of griping (in terms of optical realities) about secondary longitudinal chromatic aberration (SLOCA) with the Zeiss Milvus 50mm f/1.4 Distagon, an about $1280 lens which is highly corrected. A high level of optical correction tends to reveal secondary optical flaws (versus poorly corrected lenses, which mask/dilute them).

And so I delved into the realities of SLOCA with fast lenses; see On Secondary Color: Collective Context-Dropping regarding Zeiss Milvus 50mm f/1.4 Distagon. There, I discussed how far more expensive lenses can have as much and perhaps more SLOCA.

Now along comes the Leica 28mm f/1.4 Summilux-M ASPH, an about $5950 lens. So how does the Leica 28/1.4 Summilux do with SLOCA, at nearly 5X the price and at only 24-megapixels of detail (Leica M240)?

If you want perfection, read resumes. But if you want perfection (or nearly so) for color correction in an f/1.4 lens, there is only one answer today: Zeiss Otus.
