Based on a classic optical design from more than 80 years ago, the Meyer-Optik Primoplan 58mm f/1.9 II Lens Sony Efrom Meyer-Optik Primoplan 58mm f/1.9 II Lens Sony Eis a unique slightly longer-than-normal-length prime lens for Sony E-mount cameras. Working in conjunction with the unique optical design is a bright f/1.9 maximum aperture, along with a manual focus design, that benefits the use of selective focus and shallow depth of field techniques. The aperture setting, along with a 14-blade diaphragm, also greatly affects the quality of bokeh, with wide-open settings generating a distinct swirly bokeh quality, and stopped down settings producing a more detailed, yet smooth blur. In regard to the optical layout, a simple five-element, four-group construction is featured, along with the use of Schott glass to produce a high degree of clarity. An O'Hara Anti Reflex Coating is also applied to reduce surface reflections, minimize flare, and increase contrast. Additionally, the lens features an anodized aluminum housing that is durable, lightweight, and contributes to smooth, silent focusing performance.

E-Mount Lens/Full-Frame Format    Aperture Range: f/1.9 to f/22    Central Dispersion & Converging Elements    Schott Glass, O'Hara Anti Reflex Coating    Manual Focus Design    Minimum Focus Distance: 2'    Filter Thread: 52mm    14 AR-Coated Aperture Blades

Slightly longer-than-normal-length prime is designed for full-frame Sony E-mount mirrorless cameras, however can also be used on APS-C-format models where it will provide an 87mm equivalent focal length.

Fast f/1.9 maximum aperture allows for extensive control over depth of field, for working with selective focus techniques, and also benefits working in low-light conditions.

The optical design uses a five-element, four-group layout in which the central dispersion element is surrounded by two groups of converging elements, and the rear element has a biconvex converging design to produce notable smoothness and clarity.

Schott glass is used for high clarity and contrast, and each of the elements feature an O'Hara Anti Reflex Coating to suppress lens flare and ghosting for color neutrality.

Manual focus design permits working with subjects as close as 2' away.

Fourteen diaphragm blades contribute to a smooth and distinct bokeh quality, which can be greatly adjusted by varying the aperture setting. When working at the maximum aperture, a unique swirly quality is present in out-of-focus elements, and when working with stopped down settings, a creamier bokeh quality is produced with greater detail in the blurred regions.

Front 52mm filter thread is consistent throughout the Meyer-Optik Gorlitz version II lens series.

Related Questions and Answers

Q: 1. Will this product be returnable?

A: Yes , 30 days from the time you receive it

Q: 2. Is it rangerfinder coupled?

A: This lens is not rangefinder coupled.

Q: 3. Your website indicates that this lens is compatible with (and designed for use with) the Leica M7. But you indicate elsewhere in your website that this lens is not rangefinder-coupled. So, how is this lens to be focussed when mounted on a Leica M7 (other than with approximate focus on the distance scale)?

A: The Meyer-Optik Gorlitz Primoplan 75mm f/1.9 II Lens for Leica M is not rangefinder coupled. You do have to use the distance scale.

Q: 4. What is lens magnification factor?

A: This lens has minimum focus distance of 2.46 ' - but it is not a macro lens

Q: 5. Do I need to buy an adapter for Leica CL?

A: No adapter is needed. It will fit the Leica CL directly.

Q: 6. Is the M version rangefinder coupled?

A: Due to the unique focal length of this lens, rangefinder focusing is not supported; manual focusing must be done using live view or zone focusing techniques.

Q: 7. Will this lens be offered with the Fuji GFX mount?

A: I'm sorry, no, that would be a separate purchase.

Q: 8. Does the lens send exif info to the camera?

A: Being that the Meyer-Optik Gorlitz Biotar 58mm f/1.5 II Lens for Sony E lacks electronic contacts on the lens mount, it would not relay EXIF information from the lens to the camera.

Q: 9. Does this do autofocus at all or just manual?

A: This is a manual focus lens that is not able to autofocus.

Q: 10. The photo shows f16 and the text says f22 for max?? Which is it??

A: The minimum aperture is f/22, what you see in the photo is the depth of field scale, not the aperture ring. Basically it is not particularly necessary to show f/22 on the DOF scale.
