PERAR 24mm F4 Photo example (with Leica M-P)

1．Overview

The PERAR 24mm F4 is the fifth lens released by Ms-optics, and the third in the triplet series.

As the word SUPER TRIPLE on the lens indicates, the lens is a triplet of three elements in three groups. Ms-optics gives the name PERAR to the triplet series.

The lens is 5mm thick and the lens barrel has a flat body cap shape.

The minimum shooting distance is 0.65m, but the rangefinder coupling range of Leica M-type rangefinder cameras is up to 0.8m. A 19mm filter is screwed into the hood.

2．Usage

The compact lens is a feature of the Pela series, and it is a lens that suits small body volumes such as the MINOLTA CLE film camera, the SONY NEX series digital camera, and the LUMIX GM5.

Although it is a very compact lens, it is easy to operate, and the focus can be adjusted smoothly by sliding the focus lever at the bottom of the lens barrel. The aperture is located at the front of the lens barrel, so it can be changed by turning the hood attached to it. There are no click stops on the aperture, so the exact aperture value must be confirmed visually.

For APSC-C size sensors, the focal length is 36mm in 35mm format, which is close to the introductory focal length of 35mm for wide-angle lenses. For Micro Four Thirds, the focal length is 48mm, which is almost the same as a standard lens.

The advantage of using a small sensor is that it can forcibly eliminate the image flow and color cast caused by the curvature of field at the periphery, which are weaknesses of triplet lenses.

What is particularly noteworthy is the clarity of the depiction, and it is surprising that such image quality can be obtained with a simple lens of just three elements. You can see this in the depiction of young leaves even in the reduced images in the gallery.

Because it is a three-element lens, perfect correction is not possible, and there is some pincushion distortion and, when photographing a blue sky at wide open aperture with a full-frame sensor camera, a slight magenta color cast can appear depending on the angle of the light.

The minimum shooting distance is 0.65m, although it is not linked to the camera rangefinder, so if you use an EVF on a mirrorless camera, you can get closer.

3．Differences

Leica M-mount lenses with a focal length close to that of this lens, 24mm, are released by Leica, Carl Zeiss and Voigtlander.

The Pela 24mm is characterized by its thinness of only 5mm, and compared to other lenses, the Leica Elmarit 24mm F2.8 is 45mm, the Carl Zeiss Biogon is 47mm, and the Voigtlander Color Skopar is 25mm, making it far thinner.

The Pela also weighs 35g, the Leica Elmarit 24mm F2.8 is 300g, the Carl Zeiss Biogon is 260g, and the Voigtlander Color Skopar is 144g, making it overwhelmingly light.

The PERAR series of three elements in three groups from Ms-optics includes four lenses, including this lens, and the PERAR-35mm F3.5, PERAR-28mm F4, and PERAR21mm F4.5 are wide-angle lenses with slightly darker maximum apertures.
