iPhone 15 Pro Anamorphic Experiment – “What Makes a Cinema Camera” by Michael Cioni/Strada
For Michael Cioni, a cinema camera has to fulfill five requisites:
- Cinematic resolution
- Intraframe encoding
- High dynamic range
- Wide color gamut (10-bit or more)
- Removable lenses
For now, the iPhone 15 Pro meets four out of these five requirements, all except the last one.

FDM vs Resin 3D Printing – Which is Better?
https://www.miniwargaming.com/content/matthews-3d-printing-recommendations
<strong>NOTE: Resin printing is known to suffer from bending or warping, so it is not suggested for structural or modular pieces</strong>

Elegoo Saturn 3 Ultra Review – ACF Resin 3D printer
NOTE: You can use Anycubic water washable 8k resin with this printer.
What is ACF film (Advanced Composite Film) for resin printing?
The ACF Film features a bottom, frosted layer film that creates a softer and less suction force during printing. This remarkable attribute significantly enhances the success rate when printing challenging resins with high viscosity, ensuring exceptional results.

Canon RF 5.2mm f2.8L Dual Fisheye EOS VR System for VR photography and editing
https://thecamerastore.com/products/canon-rf-5-2mm-f2-8l-dual-fisheye
As part of the EOS VR System – this lens paired with the EOS R5 updated with firmware 1.5.0 or higher and one of Canon’s VR software solutions – you can create immersive 3D that can be experienced when viewed on compatible head mount displays including the Oculus Quest 2 and more. Viewers will be able to take in the scene with a vivid, wide field of view by simply moving their head. This is the world’s first digital interchangeable lens that can capture stereoscopic 3D 180° VR imagery to a single image sensor.
The pairing of this lens and the EOS R5 camera brings high resolution video recording at up to 8K DCI 30p and 4K DCI 60p.

LasVegas’ Sphere and the Big Sky Camera
https://theasc.com/articles/sphere-and-the-big-sky-camera
Sphere is a 516′-wide, 366′-tall geodesic dome that houses the world’s highest-resolution screen: a 160,000-square-foot LED wraparound that fills the peripheral vision for 17,600 spectators (20,000 if standing-room areas are included). The curved screen is a 9mm-pixel-pitch, sonically transparent surface of LED panels with 500-nit brightness that produce a high-dynamic-range experience. The audience sits 160′ to 400′ from the screen in theatrical seating, and the screen provides a 155-degree diagonal field of view and a more-than-140-degree vertical field of view.
The image on the screen is 16K (16,384x16,384) driven by 25 synchronized 4K video servers.

Laowa 25mm f/2.8 2.5-5X Ultra Macro vs 100mm f/2.8 2x lens
https://gilwizen.com/laowa-25mm-ultra-macro-lens-review/
https://www.cameralabs.com/laowa-25mm-f2-8-2-5-5x-ultra-macro-review/
- Pros:
– Lightweight, small size for a high-magnification macro lens
– Highest magnification lens available for non-Canon users
– Excellent sharpness and image quality
– Consistent working distance
– Narrow lens barrel makes it easy to find and track subject
– Affordable
- Cons:
– Manual, no auto aperture control
– No filter thread (but still customizable with caution)
– Dark viewfinder when closing aperture makes focusing difficult in poor light conditions
– Magnification range is short 2.5-5x compared to the competition
Combining a Laowa 25mm 2.5x lens with a Kenko 12mm extension tube
To find the combined magnification when using a Laowa 25mm 2.5x lens with a 12mm Kenko extension tube, given the magnification of the lens itself, the extension tube length, and the combined setup, you can calculate the total magnification.
First, consider the magnification of the lens itself, which is 2.5x.
Then, to find the total magnification when the extension tube is attached, you can use the formula:
Total Magnification = Magnification of the Lens + (Magnification of the Lens * Extension Tube Length / Focal Length of the Lens)
In this case, the extension tube length is 12mm, and the focal length of the lens is 25mm. Using the values:
Total Magnification with 2.5x = 2.5 + (2.5 * 12 / 25) = 2.5 + (30 / 25) = 2.5 + 1.2 = 3.7x
Total Magnification with 5x = 5 + (5 * 12 / 25) = 5 + (60 / 25) = 5 + 2.4 = 7.4x
Macro Probe Lens Comparison: AstrHori 28mm vs Laowa 24mm
https://visualeducation.com/macro-probe-lens-comparison-astrhori-28mm-vs-laowa-24mm/
https://petapixel.com/2022/11/01/astrhori-has-a-28mm-macro-probe-lens-that-looks-a-lot-like-laowas/
Overall, the Laowa did perform better than the AstrHori across all of our tests. The AstrHori lost contrast and suffered from flare when the subject was backlit. It also struggled to achieve perfect neutrality in terms of colour balance.
However, as mentioned above, the cost difference between these two lenses is significant. Considering that it costs less than half as much as the Laowa, the AstrHori is an impressive macro probe lens for the price.
