NOTE: This image is a focus stacked image of "Fujinon GF 120mm f/4 R LM OIS WR Macro lens" consisting of 10 images that were merged using Zerene Stacker Version 1.04 Build T2023-06-11-1120 (licensed). As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different to reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.

Additional Information
en: Fujinon GF 120mm f/4 R LM OIS WR Macro lens.
- Depicted with hood and rear lens cap.
- NOTE: The resolution of this image is absolutely excelling - even the tiniest scratches and a few dents, after barely 10 days of use, are visible, and also a section of a fingerprint.
This is not an omission, but is in keeping with my strive for a delicate balance, as I strictly do not aim to produce a semblance of an unnaturally polished advertisement image, but rather aim to correctly reproduce real life objects.
Of course, I do remove technical issues, such as sensor spots, stacking artifacts, pet hairs, and dust specks, i.e. things that have nothing to do with normal wear and tear or result from using the object itself.
But dents in a lens hood will certainly not be eradicated. - Focus stacked image.
