The 4:5 Image Aspect Ratio, A Large Frame Format

Cameras and Lenses: A look at the 4:5 image aspect ratio, a framing size that has transitioned through the ages and photography genres, the fundamental standard for both social media content optimization and traditional photo printing.

The 4:5 image aspect ratio, a very versatile format in photography and digital media, is particularly well-suited for mobile devices and platforms prioritizing portrait-oriented content, such as Instagram, where the images are scrolled vertically.

The format allows for a visually appealing presentation that maximizes the device's screen space, which in turn enhances visibility and engagement.

In photography, the 4:5 ratio grew out of the traditional film format from which it was first adopted.

It is perhaps the most traditional film format, where it gained prominence when popularized by photographers who used 5×4 film in large format photography, oriented horizontally for landscapes or vertically for portraiture.

With its unique visual characteristics, the frame strikes a balance between width and height, making it suitable for content from portraits to product images. It allows for a balanced composition with key elements of the image centered within the central area of the frame.

This helps to contain the eye movement in a circular motion within the center of the image, as opposed to the left-to-right or up-and-down movement with images in rectangular frames.

The format is recognized and remains a standard for art prints, with 8x10 or 16x20-inch prints. Though the image aspect ratio is not normally found as an option for frameset settings on digital cameras, images can still be captured digitally and edited to fit the format later on the desktop editor.

Many photo editing tools allow users to easily crop images to fit the 4:5 ratio without significant loss of quality. By planning shots with this aspect ratio in mind, photographers can avoid extensive cropping during post-production, thus preserving critical elements of their images.

For photographers with a vintage digital SLR with an APS-C sensor, say a Canon EOS 300D mounted with a legacy Pentacon Auto 50mm f/1.8, as in the case of the photo shoot seen here, the advice is to compose the images to fit this aspect ratio in-camera before cropping them later. This will ensure that the intended framing is preserved when the image is cropped.

Canon EOS 300D, Pentacon Auto 50mm f/1.8

Cameras and Lenses: Images with a legacy Pentacon MC 50mm f/1.8, a classic manual-focus prime lens acclaimed as a premier 'bubble bokeh monster' and an exceptional entry point into vintage glass, an 80mm full-frame equivalent on the EOS 300D.

The well-made 6-element lens in 4 groups, Pentacon Auto 50mm f/1.8, said to be a direct descendant of the equally acknowledged Meyer-Optik Görlitz Oreston 50mm f/1.8, is a compact full-frame lens with an unusually close focus distance of 33 centimeters.

The lens has a slightly rounded 6-blade diaphragm, measures 60mm in diameter and 38mm in length, weighs 194 grams, and takes 49mm filters. This lens is also well known for its 'soap bubble' characteristics, with strong and sometimes harsh outlines, and is seen as swirls on others.

The lens has also enjoyed its moment as a 'cult classic', appreciated for the bokeh effect and its very delightful and pleasant colors as seen on both film and digital.

Though optically identical, with no multi-coating on the older versions, the lens was seen in four iterations over its production run, with the oldest version having silver stripes on the aperture ring branded either “electric” or “auto”.

This was followed by the second version, which has no stripes on the aperture ring but has two silver rings at the front of the lens.

The third version has one silver ring at the front, and the focus ring of the third version has a spiked profile. The last version is all black. A late version with a PB mount is also available.

The lens enjoys a rating for Sharpness (9.0), Aberrations (8.3), Bokeh (10.0), Handling (8.7), and Value (10.0) on PentaxForums.

These first impression images with the Pentacon Auto 50mm f/1.8 were shot with the lens mounted on a Canon EOS 300D. Both the camera and lens are vintage, of course. The M42-mount Pentacon was produced from 1971 to 1978 at the factory outside of Dresden, in Germany.

The Canon EOS 300D (EOS Digital Rebel in the US, EOS Kiss Digital in Japan, and also sold as the DS6041) was the first entry-level digital SLR camera introduced by Canon, Japan, in 2003. The camera is fitted with a 6.3MP APS-C-sized CMOS sensor.
