Primarily goal of this fourth redesign, now with Solms signature, was improved image quality and smaller physical dimensions. Both demands are often contradictory and it is slight surprise that in actual picture taking the advance is readily seen.

The front lens is unusual with its plane surface. At full aperture the lens is indeed sparklingly clear, even in high contrast situations. Generally this lens is one full stop ahead of the predecessor. The specific fingerprint of this lens is a high correction of the oblique sagittal rays, which does improve the rendition of fine gradations in tiny object areas. This is an outstanding lens with a clear rendition of very fine details in deep shadows and highlights alike with retention of crisp outlines in high contrast situations. The 1993 version of the Elmarit-M 28mm shows many characteristics of the classical era of Leica M lens design. This clarity of very fine textural details is a hallmark of many modern Leica M lenses. In addition to high overall contrast the lens is effectively free of flare and veiling glare. The lens mount is very solid and a fine example of the classical mechanical tradition that Leica is upholding till today.

An even more compact and yet better design is the current Elmarit-M 1:2.8/28mm ASPH.
