Very cool!

Haha, I’d not heard of that incident - but love it!

Listening to Edmonton’s CBC Radio 1, and I’ve just learned that SCTV is going to be re-released.

Unfortunately, it’ll be streaming on Prime, rather than on its proper home: CBC.

Fucking Bezos.

To be fair, that black goo is worth at least $100k on its own.

I have a Nikkor-OC 35mm f/2 that I’m quite fond of. So, after careful consideration, I think I’ll give this Leica a pass.

It’s apparently the only brass-bodied, nickel-plated-then-chromed example of this lens, with this optical formula, in existence.

There was a Dumble guitar amplifier listed for sale on Reverb a while back, for an amount similar to this. I added it to my cart for a chuckle, which is probably what’s going on here.

β€œHey honey, whaddayathink? Should I go for it?”

That’s excellent. And yes, this is insane.

My dude. If I could afford this lens, I’d fly over to Toronto in my G800 and pick it up myself.

(Cool lens, tho.)

Haha, fair enough. I’ve just found that Ray-Bans work for my facial structure.

Ray-Ban frames have been my go-to for many years now - I’ve had at least 8 pairs made with prescription lenses (both clear and tinted).

It’s looking like I’ll need to find another designer, and I’m not happy about it. But I don’t want anyone to ever even suspect that I’m wearing #PervertGlasses.

This has been on my Kanopy watch list forever - thanks for the nudge; I’ll be watching it tonight!

Wonderful photo and print, Mark!

I've finally assembled my dream set of Nikkor LF glass (90mm f/8 SW, 135mm f/5.6 W, 150mm f/5.6 W, 200mm f/8 M, and 300mm f/9 M - all with matchy-matchy Copal shutters), but your Ektar posts are *still* giving me G.A.S.

They're that pretty.

I just recently picked it up (so recently that I've not yet had the chance to take any photos using it), but the view through it is so glorious that I immediately found another for use with my 135mm Hektor.

That's a beautiful collection of glass and metal you have there.

I have a bog-standard, mid-sized, internal combustion-powered SUV β€” but drive it so rarely that I haven’t fueled it up since Dec. 28 (and the tank is still >1/2 full).

Beauty! I love Barnacks. Here's hoping that haze and fungus haven't found their way into that Summitar!

Sounds fine to me - though please refrain from activating your chemical defenses while holding the pose during class!

Damned cool. I wish I could justify purchasing it, but alas.

And it's at my favourite camera shop, no less!

I wonder what the odds are that the offshored tariff money is funding Russia's war against Ukraine.

A lot of people say AI isn't very good for the world and its outputs are routinely unreliable, but these haters fail to see how it's revolutionizing how we incinerate schoolchildren.
