The Glimmer Glass is one of the many types of diffusion filters made by Tiffen that produces one of many different types of Diffusion effects. While they all diffuse light, they are not all the same and do it in their own way and the use-case will vary pretty significantly. See how the Tiffen Glimmer Glass filter is different from the rest.
This lens is a delightful addition to the m-mount system. Its sharpness is commendable, especially at f2.8, although it still holds up well even at f1.5. In very bright lighting, you may notice some ghosting at the fastest aperture, and occasionally there may be some flaring with a noticeable arc. Nonetheless, the bokeh is beautifully vibrant with a touch of swirl in the foreground and only slight chatter and swirl at the edges in the background. This telephoto lens stands out due to its stunning color and contrast, and the overall character it creates at f1.5 and f2 is truly enchanting. While it's not a flawless lens, Voigtlander's 7-element design gives it a unique and classic look with a captivating bokeh.
The Zeiss Planar 50mm f2 lens is a true gem in the world of photography. It has earned its reputation as the standard lens for the ZM system and for good reason. This lens offers exceptional image quality, with incredibly sharp details and a consistent rendering that is hard to match. Its T* anti-reflective coating ensures that even in difficult lighting conditions, the lens produces images with minimal flare and ghosting.
The Voigtlander 35mm f2 Ultron is a very compact full-frame manual lens for the Leica M mount. The lens includes one aspherical element which helps improve the corner-to-corner image quality making this lens great for casual photographers looking for a good low-profile walkaround lens. While the image quality is surprisingly good for a lens this size, the rendering characteristics are sometimes a little unpleasant at times.
