A leisure walkthrough with Canon EF 50mm STM Lens

The Canon EF 50mm STM Lens was an extremely popular camera back in the day when it produced good stopped-down images and prime-wide aperture. The Canon company had just celebrated the EF 50mm product and since then, a lot of significant changes were made on this ultra-small camera in terms of its size and weight to mention a few. The Canon EF 50mm STM lens has a Super Spectra Coating and a much improved manual focus ring since its upgrade. The 50mm focal lens is one of its advantages to most users and they are usually used for events like weddings, lifestyle, architecture, general studio photography, documentaries, and sports. Besides, this camera’s focal length suits with panorama images and they are applicable for shots on less tightly-framed head and shoulders, full body portraits or partial body too. Their wide aperture feature allows users to control the action-stopping shutter speed and enable more light to reach the imaging sensor effectively. The camera comes with a 2.72 x 1.55’’ manufacture spec size and a 0.48’’ focus extension length. The measuring size is 2.77 x 1.83’’ with a 3.03/3.03’ hooded lens length. The maximum magnification for this type of camera is 0.21x and the magnification range extends to 0.45-0.24x on using a 12mm Ext tube and a 0.74-0.53x in the case of 25mm Ext tube.

Speculations on their featured lens

The Canon EF 50mm STM Lens weighs 159 grams and the length is 39mm. This particular lens in the camera gives a strong coma in the periphery of any image circle at the widest aperture and it is recognized by a sharp detail contrast towards the centre of the image. The flair is close to non-existing state as they result in a mild amount due to the low lens element/group count and the stop-down goes to f 5.6 or beyond. Further, the camera’s coma lessens the aperture it diminishes at f/4. When a straight line runs near and parallel to the edge of a full frame image, the lens would have a slight amount of barrel distortion and their blurred portions of the image are rendered by the updated lens for a more pleasing result as compared to their predecessors. The Mini RV20 differs from most cameras on their out of focus highlights by using the widest apertures, all lenses becomes rounded out of focus specular highlights.

Structures and designs of the camera

Again, 11 lenses with two polished and ground aspherical lens element make up the optical construction. These lenses’ aperture design is a vital factor to the shapes with blade counts when it performs a stopped down operation. The 50 mm options also offer a much better sharpness when it is stopped down beyond f/2.8 and it is made up by plastic extremities, mounts and with a metal body. These lenses are powered by ring-type USM motors as the lens use a floating front extension focusing system. The front of the lens extends while focusing although it may not be rotatable as these are accompanied with professional L series autofocus lens.
