800mm 1/50th of a second -> that is truly amazing! You really have to have experience shooting 800mm lenses barren of IS, to really appreciate how amazing it actually is! Well done! I had not read that the RF 800 f11 didn't use the whole sensor …

Great focus on the eyes! High ISO are just normal when shooting at 1/2500th and higher. Shooting snowy owls ( +1 stop or more of + EC ) in sunlight at f8, in Barrie Canada, at shutter speeds of 1/3200th at f4 in snow fields, would require ISOs of …

I already own the Canon RF 24-105, and the 24-240, as well as a Laowa Venus optic 15mm f2.0 mechanical lens ( love it too ) in addition to a closet full of EF glass, so I am pretty set. From Rockwell's site, I think, the RF 100-500 with foot …

I found a review by soft spoken, reserved Ken Rockwell for the RF 100-500 and he was quite positive about its optics, weight, and build quality - but he did say one could get most of its benefits with the older EOS EF 100-400v2 with an EF to RF …

I've kinda had my eye on the EOS RF 100-500 f4.5->7.1 IS L - Seems like the larger aperture might be more useful than f11, but that's just a wild ass guess... It does accept the 1.4 RF TC At just 3 pounds it might be easier to carry than an EF …

Great focus and great captures! Manual mode, set the shutter speed and aperture of your choice, and auto ISO. What is the shipping version of the firmware in your R5? There have been several firmware updates since the original introduction …

A recent article in Science,from the Karolinska Institute, proposes a mechanism explaining why Sars Cov 2 is so deadly in about 14% if the sickest patients - they seem to lack interferon type 1, either due to lack of production or because they …

Wow! What a story. You will laugh about this in a couple months, after a few beers with your mates - so it must have been an adventure...... Adventures are rarely fun when you're living through them though.. I hope the kids weren't too …

Just like cars parked and not driven for too long........... Complex mechanical devices frequently fare better with moderate, not infrequent, usage. I need to go for a long drive again--- road trip time.

Interesting, in your graphic drowning is the third leading cause of death after being stabbed or poisoned. Indeed, causes of death in the Middle Ages were legion, and drowning rated very …

So many trains, so little time......

Ravens are a favorite of mine as well.....

I know of a number of trains that perform a similar journey - out from a station, to a destination maybe an hour or so away, and then turn around and return to where they departed from with their original load of passengers - many of these trains …

There is a great 1 hour video about hummingbirds by Richard Attenborough on Amazon Prime titled “Hummingbirds”. @Chris you’ll love the high speed filming - just a great long look at hummers, eating, flying fighting and mating

Harley deserves real kudos for preparing the bikes for this adventure. I see Harley-Davidson lists the Live Wire electric motorcycle on its web page for a mere $27,799 + $390 shipping fee I haven't priced motorcycles recently, but that does seem …

I'll be joining you soon - I can now sign up for HBOMax and stream "Raised by Wolves" - so careful with the spoilers now 😄 What a great title - like the founding of Rome... Romulus and Remus. raised by the She …

I mentioned the use of convalescent serum last February as a potential treatment that was being explored in Wuhan and elsewhere. It has taken less than 6 months for real progress to occur in this area - Eli Lilly is announcing the production of …

This looks very interesting - HBOMax streaming - worldwide maybe??? Edit added a day later ------ I checked on Apple TV+ and "Raised by Wolves" is available on HBOMax via streaming in central Indiana, and thus, I suspect the entire USA. I am not …

I suspect this is a result of numerous lawsuits over children being injured or killed by misadventures with furniture. Chests of drawers have been in general use since the late 17th century - almost 350 …

I love this article which I just found by searching for threads about dogs. I was looking for a discussion of how long humans have been pairing with dogs - I have seen several articles over the last year suggesting that the human cainine pairing …

Even with IBIS, I'll bet the 800mm F11 will do better with some strategic bracing, rather than handheld. I chase my butterflies at home with lenses from 600-840mm equivalents and find them pretty mobile until I rest something on a stable platform …

Hello to an Iowan, from a Hoosier! 😄 Was Hoosier even an offering on your list? My pharmaceutical insurer for what Medicare doesn't seem to cover, sends me a statement each month delineating what they have paid, what I still owe, and what …

What a cool set of sand statues - way cool, @Denise

Students are returning to college all over the country. This photo from San Diego State needs no comment - it speaks eloquently itself....... You can ignore the text, I post this link, for the image, not for a discussion of Stoics. My estimate is …
