NOTE: This image is a focus stacked image of "Fujinon GF 30mm F5.6 T/S lens" consisting of 41 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 than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions. العربية ∙ Deutsch ∙ English ∙ español ∙ français ∙ 日本語 ∙ македонски ∙ português do Brasil ∙ русский ∙ slovenščina ∙ ไทย ∙ українська ∙ 中文（简体） ∙ 中文（繁體） ∙ +/−

en: Fujinon GF 30mm F5.6 T/S lens.

• This is a medium format tilt-shift lens.
• The lens is depicted in vertical position with both front and rear caps attached.
  Move mouse pointer over image to view the relative positions of each component.
• The knobs and scales for tilt (at centre right) and shift (at lower left) control are clearly visible in this image. Both are currently set to zero position.
• Tilt and shift mechanisms:
  • The tilt mechanism (nearer to the front lens) allows an angular movement of up to ±8.5°.
  • The shift mechanism allows a sideway movement of up to ±15 mm.
• This lens is equipped with two mechanical levers that control rotation (press lever towards camera body to enable function):
  • Lever that enables rotation of tilt element (hidden at rear): allows rotating the tilt component of the lens by 90° in relation to shift component.
  • Lever at lower right that allows rotating the whole lens by ±90° versus the default landscape position.
• Locking elements (all positioned on the two counterfaces invisible in this image):
  • Both tilt and shift components possess opposing, smaller knobs that operate locking screws which both increase friction and secure the chosen tilt and/or shift positions.
  • The tilt component possesses an extra slider lock that retains the lens incline to its zero position.
• The lens may be attached to a Fujifilm GFX medium format body via its Fujifilm G-mount.
  • Both tilt and shift data are automatically transferred to the camera and are stored in EXIF data; this, though, requires a recent Fujifilm GFX100 (II) / GFX100S (II) camera model and, possibly, a software update to the camera.
• Image taken in Aplerbeck, Dortmund, Germany in November 2023.
• High resolution focus stack composed of 41 images taken with the Fujifilm GFX100S automated focus stacking function.

de: Fujinon GF 30mm F5.6 T/S Objektiv.

• Dies ist ein Mittelformat Tilt-Shift Objektiv.
• Das Objektiv ist in senkrechter Lage abgebildet, mit Frontdeckel und Objektivanschlussschutzdeckel.
• Sowohl der Drehknopf für den Kipp- (T=tilt mitte rechts) als auch der des Verschub-mechanismus (Kennbuchstabe S=shift, hier unsichtbar links) sind dargestellt, beide in Nullposition.
• Das Objektiv wird über das Fujifilm_G-Bajonett an eines der Fujifilm GFX Mittelformatgehäuse angeschlossen.
• Aufgenommen in September 2023 in Aplerbeck, Dortmund, Deutschland.
• Hochauflösende Focus Stacking-Aufnahme aus 41 Einzelbildern.

Technische Daten zum Bild: siehe nachfolgende Beschreibung im englischer Sprache.

• Extended colour rendering: This is a true ProPhoto RGB colour space image. All editing has proceeded on a 16-bit basis, based on the original 14-bit RAW file. The JPEG file format definition does allow a 16-bit colour space, but only the 8-bit variant has ever been realised in available image rendering software. Thus this image must be saved as an 8-bit JPG file, nevertheless retaining the ProPhoto RGB colour space.
  If, as opposed to most modern equipment, either your computer or your screen's colour rendering hard-/software does not support 8-bit ProPhoto RGB JPEGs (i.e. supports only JPEGs based on the sRGB colour space), this image may appear somewhat dull both in colour and tone spectrum.

• [5] FOCUS STACK recording: camera attached to sturdy tripod, electronic shutter, activated feature 'focus bracketing', set focus bracketing parameters in corresponding deep menue settings: AUTO, interval: 1sec., set to near focus (viewfinder pos. A), then set to distant focus (viewfinder pos. B), total focus distance covered: approx. 130mm (from nearmost focus to the most distant focus spot), image series taken automatically after pressing release button; took 41 images, both as (8-bit) JPG and 14-bit RAW (.RAF) files, colour space set to 'Adobe RGB'.
• [6] Adobe Lightroom: imported all 41 14-bit 'Adobe RGB' RAW (.RAF) files (a) Applied current standard preset 005 (WB, tint:unaltered, Exposure+0.90, Presence: Texture+30 Clarity+30 Vibrance+5 Saturation+3, Sharp: Amount+70, Radius:1.0 Detail:25 Masking:20, NoiseRed: Lum:50 Detail:50 Contrast:0 Color:30 Detail:50, Smooth:50, LensCorr:AUTOMATICALLY derived from .RAF file) (b) Subsequent changes (final values stated): Exposure now:+0.00 Texture+50 Vibrance+10 (c) tone curve: UNALTERED (d) WB (white balance) 5900K, tint:+15 (e) exported as TIFF/16-bit, 'ProPhoto-RGB' colour profile.
• [7] FOCUS STACK processing: (a) tool 'Zerene Stacker' 1.04 (b) stacked all 41 JPG images via 'PMax' method (c) Stacking artefacts: NONE (i.e. no focus-based retouching required at this stage) (d) exported as one TIFF/16-bit 'ProPhoto-RGB' image.
• [8] Adobe Photoshop: (a) imported stacked TIFF/16-bit image, explicitly preserving embedded colour space 'ProPhoto-RGB' (b) removed sensor specks and all visible specks of dust and strands (c) masked: YES, lens (d) tone spektrum (d1) lens as main object: unaltered (d2) background: added a gradient to the mask (short-distance transition from black upwards to white bordering transparent plane beneath object); then set to almost pure white (20>255) (e) enhanced sharpness: NO (f) rotated: NO (g) cropped: NO (h) saved as .PSB file (i) rendered the intermediate 'ProPhoto-RGB' TIFF/16-bit version via "copy as" as this final 'ProPhoto-RGB' 8-bit JPG file at max. quality level (12 of 12).
