After some years using this social media platform, and after being censored, I decided to go back to the old blog+RSS model, I recommend anyone to stop centralizing their content around private corporations that doesn’t respect privacy and freedom of expression, you can find my content on RodrigoPolo.com, I recommend using a RSS readers from now on.
As any videographer enthusiast, I’m exited over the release of the Metabones Canon EF to RF Speed Booster ULTRA 0.71x, but it got me thinking… Why they decided to go with a 0.71x crop factor insted of 0.64x like the XL EF-Mount to MFT, and I believe the reason is… the market.
Many enthusiast have transitioned from crop cameras to full frame, then from Canon to Panasonic GH4, GH5 and GH5s using Canon glass adapted with a Speed Booster, and one of the most popular lens options was the Sigma 18–35mm f/1.8 …
Almost a year ago I wrote about this topic, but I forgot to include the extra crop you get while using IS and the image quality loss you’ll get while recording 1080p.
Most pixel-peepers hate soft images, and is kind of sad to realize that the Full HD video (1920x1080px) from the EOS R, even though uses the full width of the sensor, it resizes the image using a simple downsampling algorithm called pixel binning.
There are plenty of downscaling algorithms: nearest-neighbor interpolation, bilinear and bicubic, box, sinc and lanczos resampling, etc. The ones that render the best results requires…
Analog aspect ratios were defined by the medium and anamorphic lenses used, but in the digital era, I have seen many clueless people share different approaches that do not take into considerations some key aspects of this format, even profesional Blu-ray release lack some undesrtanding on the way Cinemascope video should be handled.
The digital medium doesn’t like decimals or fractions, though most tech people know the 1995 Alvy Ray Smith’s Memo titled “A Pixel Is Not A Little Square”, at the end of the road, digital video is made by square pixels. Blue-rays and digital cinema projectors have some…
I have read that many users can’t find the EOS Utility 3.9.0 download for the Canon EOS R while running macOS Mojave 10.14, the official Canon EOS R download list doesn’t show support for the latest Apple OS, but the software for the previous macOS software works just fine.
Ok, this is the third time I’m writing about aperture values trying to figure out something that is puzzling, I reviewed the concept of aperture in lenses and why the Micro Fourth Thirds System has a hard time trying to emulate a full frame result in the two lasts posts:
First, let me show you a picture I have taken using the Sigma 18–35mm ƒ/1.8 with the full frame camera Canon 6D:
As you can see, the vignetting is quite evident, this is because this lens isn’t designed for full frame cameras but for crop cameras, nevertheless it can be…
