Prior to posting this one, I decided to try and learn some more about the concept of 'infinity'... Perusing the link as well as others reminded me of my own semi-successful pursuit of quantum mechanics (my head still hurts :unsure: ;)...much like it did while trying to figure out the plot of...

...so much of this stuff is use-dependent--Camera Connect to an iPhone works well, for a small number of image files, even if only used occasionally. I just tested it myself (iPhone 12 ProMax from M6MkII...using home WiFi). I probably move files this way a 4-6 times a year. In a pinch, out in...

[I need a fingers-crossed emoji here.] ...somewhere I have a Canon-branded SD card...16MB? It goes back a quarter-century or so, I guess. So like many reading this, I have had more than two decades of experience with SD (and CF) cards...experience with what must be dozens of cards (if I...

I have not. Great question, though. After perusing this: https://support.usa.canon.com/kb/index?page=content&id=ART181997 ...in the absence of a laptop, I think I'd first consider off-loading travel images to a large capacity iPad (for Apple folks)!: https://support.apple.com/en-us/118280...

https://www.thephoblographer.com/2024/04/08/the-canon-digicam-that-changed-everything/ I owned one of these; replaced it with an S95. I 'shot' some great concerts with the (still functioning) S95. I would pay a premium for a 2024 version of the S95; tiny, light, responsive and well-specced...

M6MkII + 70-300 II IS (adapted) on a monopod Don't let anybody tell you otherwise--as far as solar eclipses are concerned, totality is where it's at!

What I think I know, based on both experience and education... is that the engineered plastics used by most lens manufacturers are far more resistant to 'failure' than expected. What matters (some) is a given material's ability to absorb/dissipate energy, in terms of protecting what's inside...

...why I read CR. Thanks for posting.

...yet another thoughtful and informative post from GMC...keep them coming. As for the peanut gallery? Just chuckle and move on--the internet is a wonderful thing, until it's not. I for one always look forward to your comments here on CR...going back to your nuanced views of Fuji gear.

Sporgon: can you define 'accurate exposure' in terms of your own particular usage? I have a quite distinct memory at my amazement at the effectiveness of utilizing the tiny wheel on the back of a Canon S95 to rapidly adjust exposure compensation while attending several rock concerts...concerts...

For some reason, our neighborhood's female Cardinals played hard-to-get for me and my 5DMkIII/100-400II+1.4XIII set-up during the 2023 calendar year. But in March 2024, love is in the air. 13 seconds elapsed between the two images that follow: ...the young lady seems to staring intently...

My own 'serious' travel photography, in some ways, began at Disney World thirty-five years ago. Reading layoff details in this thread reminded me of Disney's "exploits" nearly a decade ago. https://www.nytimes.com/2015/06/04/us/last-task-after-layoff-at-disney-train-foreign-replacements.html...

I agree. Good conversation. And for those who think that some of the (far-out?!) subscription models will never see the light of day...I give you this: https://arstechnica.com/gadgets/2024/02/hp-wants-you-to-pay-up-to-36-month-to-rent-a-printer-that-it-monitors/ ...and I have not read every...
