MY SONY 55mm FULL-FRAME LENS

MY SONY 55mm FULL-FRAME LENS

Today I used my Sony 55mm Full-Frame lens with my Sony FX30 which has a crop sensor.


I was one of the first to embrace Sony Mirrorless cameras but their initial cameras were APS-C but early on as I had decided that I would eventually switch to full-frame cameras I purchased full frame lenses rather than APS-C lens even though they were much more expensive. The Sony FE 55mm F 1.8 ZA was one of my first full-frame (mirrorless) lenses.

The Sony FE 55mm F 1.8 ZA lens, where ZA indicates that it is a Zeiss lens, was introduced on October 16, 2013.

This lens was one of the first fast-aperture, “standard” focal length prime lenses available for Sony’s full-frame E-mount system.

The lens is known for its exceptional image quality and compact size. It has a 7-element, 5-group optical design that includes three aspherical elements to minimise aberrations. Its relatively fast F1.8 aperture makes it a good choice for selective focus work or shooting in low light. The lens is extremely sharp, shows little chromatic aberration or distortion, and has entirely acceptable levels of vignetting. These features make it a high-performing lens, living up to its Carl Zeiss branding.

As for using this full-frame lens on a crop-sensor body like my Sony FX30, it is technically a good idea. Full-frame lenses can be used on crop sensor cameras as long as they are compatible and able to be mounted. The lens area on full-frame lenses is larger than necessary for crop sensors, so the crop sensor will still apply a crop factor that will create a narrower field of view and alter the effective focal length. However, the image quality of the lens does not degrade when used on a crop sensor body. In fact, full-frame lenses used on APS-C cameras often perform slightly better because the edges of the light circle cast by the lens, where most of the weaknesses of a lens are most obvious, are cropped off by the smaller sensor.

So, even though full-frame lenses are more expensive, my decision to purchase full-frame lenses for my APS-C camera was a sound one, especially considering my plan to switch to a full-frame camera in the future. This way, I was already equipped with high-quality lenses that you can continue to use when you make the switch.
