Canon EOS R6 vs EOS 5D Mark IV Comparison Review

Canon Firmware Canon EOS R6 Review Camera Sales

Not sure how much these two cameras compare but never the less here is a Canon EOS R6 vs EOS 5D Mark IV comparison.

Always interesting to see how different cameras from different times (or shall I say “epochs”) compare. The Canon EOS 5D Mark IV, likely the last of a line of professional workhorses, and the EOS R6, Canon’s more affordable last gen mirrorless camera. Kevin Raposo compares the two cameras in the 17 minutes video below.

The EOS R6 sports many features shared with the EOS R5, a class leading autofocus system for instance, and the R6 has an imaging sensor derived not less than from the flagship EOS-1D X Mark III. For more Canon EOS R6 review stuff see here. User manuals are available for download for the EOS R5 and the EOS R6. Canon EOS 5D Mark IV reviews are listed here.

Canon’s High Resolution EOS R Camera Might Have More Than 100MP

High Resolution Eos R

A new rumor surfaced, suggesting the upcoming high resolution EOS R camera might have an image sensor with more than 100MP.

So far a sensor resolution between 80MP and 90 MP has been the trend among the rumor mills (ours included). The source of the rumor is confident that Canon will curb the sensor resolution well beyond 100MP. The reason is to “provide even more separation between the EOS R5’s 45mp and the new high-megapixel sensor“. According to the rumor, this upcoming high resolution EOS R camera will be oriented to towards landscape and studio photographers and have a different form factor than the EOS R5. The camera will replace the EOS 5Ds and EOS 5Ds R.

Stay tuned, stay safe.

Canon Jointly Develops Advanced Chipmaking Production Technology, Report

Coronavirus Covid-19 Ransomware Chipmaking

Canon enters a new production domain: advanced chipmaking production technology. The effort is supported by the Japanese government and is a joint venture with other companies. The semiconductors are going to be used for industrial applications

Reports Nikkei Asia:

TOKYO — Three of Japan’s leading suppliers to the semiconductor industry will join hands in a government-supported effort to develop advanced chipmaking production technology, Nikkei has learned.

The initiative brings together Canon, which builds semiconductor lithography machinery; top Japanese chipmaking equipment supplier Tokyo Electron; and Screen Semiconductor Solutions, which makes wafer-coating and -cleaning machines.

The effort, which comes as Japan seeks to regain lost ground in the global semiconductor race, will include an element of cooperation with such international players as Taiwan Semiconductor Manufacturing Co. and Intel, people familiar with the matter said.

The Japanese trio will cooperate with Japan’s National Institute of Advanced Industrial Science and Technology, with the Ministry of Economy, Trade and Industry (METI) to provide roughly 42 billion yen ($386 million) in funding.
