Digital Teleconverters Are Better than You Might Think - TDS Photo Podcast

This is The Digital Story Podcast #796, June 22, 2021. Today's theme is "Digital Teleconverters Are Better than You Might Think." I'm Derrick Story.

Opening Monologue

Thank you so much! Humans can have amazing memory when it comes to bad things. A linger disdain for dogs because one chased you in second grade, or a bias against digital teleconverters because you zoomed out to 10X in 2005 and were horrified by the results. But things change, and this week we're going to revisit the modest, but useful 2X teleconverter that may be languishing in your mirrorless camera. I hope you enjoy the show.

Digital Teleconverters Are Better than You Might Think

Today I'm going to talk about the joy of digital teleconverters (pause with laughter). No, I'm serious!

I'll start with a story from Father's Day. (Tell the story of taking pictures at the Presidio in San Francisco.)

So I dashed out the door with the Fujifilm X100V and my iPhone 12 Pro Max in my pocket.

On our walk along Crisy Field, I notice a nice view of the Palace of Fine Arts with the San Francisco skyline in the background. I composed the shot with my X100V, but the lens was just too wide for the composition that I wanted. So I used the built-in digital teleconverter set to 70mm.

This digital teleconverter, like the 2X on my Olympus cameras, provides the magnification at the native resolution. So, if the RAW file is 26MP, so is the magnified Jpeg. (Footnote about the firmware improvement that allows you to use this function in RAW+Jpeg mode.) If you want a true safety net, then shoot RAW+Jpeg and record the scene with each version.

Back home, I opened both images in Capture One Pro, cropped both the RAW file and the magnified Jpeg to the same proportions, and compared the two files. Here's what I observed.

  • The cropped Jpeg measured 5,479 x 3,331, giving me ample resolution to print and play with. The cropped RAW file measured 2,748 x 1,755, which is fine for web work, but not much beyond.
  • At Fit in Window magnification, the two files looked equally sharp. It would be difficult to tell the difference.
  • At 200 percent magnification, the Jpeg held its own compared to the RAW file at 400 percent magnification, which was needed to provide the same framing. The Jpeg had a bit more smearing of detail, and the RAW had some pixelation due to its magnification.
  • Another difference I could tell between the files was the tonal gradation was a little smoother with the RAW file, than with the Jpeg. But this would likely happen without any magnification is is just the difference between these two formats.
  • The RAW does provide access to tools such as defringing and RAW sharpening that are not available for the Jpegs.

I've posted the full size comparison files on my Flickr account, so you can download them and look for yourself. But the bottom line is, the Fujifilm digital converter gave me the reach that I wanted, but at a small real world cost quality wise.

Canon Rebuffs Rumors That Its R3 Sensor is Made by Sony

You can read the entire article on Petapixel.

Since Canon's initial development announcement for the EOS R3, rumors have swirled that the company -- despite its statement otherwise -- was not the manufacturer of the backside illuminated sensor at its core. A report published on June 17 stated factually that the R3 sensor is made by Sony, and Canon has responded.

As PetaPixel reported on April 13, Canon stated that the upcoming EOS R3 sensor "will feature Canon's first-ever full-frame backside-illuminated stacked CMOS sensor that it designed in-house."

Nearly a month after Canon's R3 development announcement, Canon News and Canon Watch noticed that some language had been adjusted on Canon UK's website. What once stated "designed and manufactured by Canon" was adjusted to "developed by Canon." This was the first in a set of reports that would surmise that Canon was not the maker of the sensor.

On June 17, these rumors finally culminated in a story published on EOSHD that definitively stated based on documentation of a new Sony sensor -- the IMX554DQC -- the EOS R3 sensor would not be made by Canon but instead would be a Sony product.

Editor's note: After publication, the EOSHD report was edited. The below quotes are from the original story.
