Interesting Canon EOS R Fact

It has been raining and mostly cloudy here on the USA east coast practically all summer. The funny saying goes something like this: "It rained twice here this summer, once for 6 weeks and once for 7 weeks." Those dark weather conditions greatly challenge outdoor camera and lens testing as any clouds in the sky can mean unequal shot-to-shot lighting.

At the other end of the spectrum is Colorado, currently experiencing an extreme drought with reservoirs at historic lows (Crater Lake in the Maroons Bells Scenic Area was empty). So, it would make sense that clear skies could be found there.

Amazingly, the day I flew out to Colorado, it was clear here and I arrived to heavy clouds, rain and snow that lasted practically my entire time there (note: I'm available to hire for rain-making). Thankfully, the night before I left was clear and I was able to do some night sky camera and lens testing.

Focusing on stars at night is always a challenge and the Canon EOS R's EVF proved up to that task. I have been very impressed by the R's low light AF capabilities, especially with the Canon RF 50mm f/1.2L USM Lens mounted and when that lens took its night sky turn, I decided to try autofocusing on a bright star. Under my local modestly-dark sky (this light pollution map shows this location as between yellow and green and some town glow is seen in the bottom of the included image), the EOS R with the center AF point selected successfully and repeatedly autofocused on bright stars. This task does not get easier.

Before you ask me about specific EOS R and lens combinations being able to do this, know that I returned back east to heavily clouded skies and it has been raining heavily all morning.
