Anamorphic lens

With a 1.25× or 1.20× anamorphic widescreen lens mounted, live view and photos are desqueezed in the camera into a wide frame with normal proportions.

Built into GRLife Pro 2.x · Build firmware GRLife Pro 2.x guide

After flashing, switch it on on the Features page of GRLife Pro in the camera.

What it does

  • Pick your lens’s ratio on the Features page of GRLife Pro: Off, 1.25× or 1.20×
  • While the lens switch is on, the aspect ratios become three wide ones: Wide 1.88:1, Wide 2.22:1 and Wide 2.71:1 (at 1.20×: Wide 1.80:1, Wide 2.13:1 and Wide 2.60:1)
  • Live view shows the desqueezed picture; the last two ratios have bars and white lines at the top and bottom, and the guides are placed within the final photo
  • JPEGs are desqueezed in the camera and stay 6000 pixels wide: 6000×3200, 6000×2688 and 6000×2208 at 1.25×; 6000×3328, 6000×2800 and 6000×2304 at 1.20×
  • RAW (DNG) keeps the original sensor data and gets a desqueeze tag; with RAW+JPEG, the preview inside the DNG is desqueezed too
  • Each photo remembers the ratio it was shot with, so moving the switch after a shot does not affect photos still being processed

How to use it in the camera

  1. Mount the lens, then set “Anamorphic lens” to your lens’s ratio on the Features page of GRLife Pro.
  2. Pick the aspect ratio in MENU › Image Capture Settings › Aspect Ratio, or in ADJ.
  3. After taking the lens off, set the switch back to “Off”.

Requirements and limits

  • Desqueezing compresses the picture vertically and keeps its width, so photos are less tall than at the stock aspect ratios.
  • While the lens switch is on, processing after each shot takes a few seconds longer than usual.
  • With RAW only, the preview in camera playback still looks squeezed; the file itself is fine and is desqueezed from its tag on a computer.
  • The freeze frame right after a shot is not desqueezed; the bars are hidden while the ADJ quick menu is open.
  • While the lens switch is on, multi-exposure (half frame included) and interval composite photos are not desqueezed, and the height recorded in the photo information does not match the picture.
  • Only in GRLife Pro 2.x; the GR IV is not supported yet.

Testing status

Tested on a GR IIIx 1.71 (JPEG, RAW and RAW+JPEG, both ratios). The GR III and the other firmware versions run the same code and are verified offline. Keep the stock firmware to flash back.

FAQ

Should I switch it off when the lens is not mounted?

Yes. While the switch is on every photo is compressed, so pictures taken without the lens come out squashed.

Are RAW files desqueezed?

The RAW data stays as it is, and the DNG carries a desqueeze tag. Photoshop (Camera Raw) desqueezes it automatically when opening; software that ignores the tag shows the squeezed original.

Which lenses are supported?

Anamorphic widescreen lenses with a squeeze ratio of 1.25× or 1.20×.

Does it work on the GR IV?

Not supported yet.

What happens after flashing back to the stock firmware?

The lens switch lives only in GRLife Pro; after flashing back, the aspect ratio returns to the stock options.

Custom firmware, test version · The result is unofficial firmware and flashing carries risk; back up first and keep the official firmware.
