Death of the Dust Trombone: Canon Replaces Legendary 100-400mm Telephoto Lens – Good-Bye Push-Pull Zoom

Tuesday, November 11th, 2014

Canon’s aging beast, the Clinton-era EF 100–400mm f/4.5–5.6L IS USM lens is no more – after 16 years of production, it’s being replaced by the EF 100–400mm f/4.5–5.6L IS USM II, a more conventional design. 

Here are some “dust trombones*” right here, back about a decade ago, all extended to the 400mm telephoto setting, the better to see the Blue Angels over Fort Mason, my dear:

The thing about the old lens is that it offered IMAGE STABILIZATION (IS) plus an “ULTRASONIC” MOTOR (USM) (for fast auto-focus) in the same package. At the time, Nikon couldn’t keep up, so it would make you choose betwixt one feature or the other, if you were lucky. Nikon lost a lot of customers during the Aughts for just this reason.

Read all about it.

I’m sure the updated lens will be better (and of course, lots pricier) in most respects.

Adieu, push-pull lens.

*Pull it in fast enough and you can feel the breeze on your face, since all that air inside needs to go somewhere…

Dolphin Roundup 2011: The Best San Francisco County Dolphin Sightings of the Year, Plus Babies From Years Past

Friday, December 2nd, 2011

I’ll tell you, I was shocked when I found out that you could see dolphins while just walking about San Francisco.

Like this, from Lands End, from a while back:

Now I personally didn’t take any new shots this year, but here’s a roundup of the best shots from 2011 so far:

From Fort Winfield Scott, The Presidio – jump jump!

From Ft. Winfield Scott – jumping the other way

From the Golden Gate Bridge – see the shadow? 

From the Golden Gate Bridge – bottlenoses

From the Golden Gate Bridge – at 200mm

From a boat – Pacific white-sided

From a boat – northern white whale dolphins

From a boat near the Farallones – Risso’s

Castro Street Fair – tattoo category (Uh, law school called – they want their diploma back)

That was 2011, now here’s yesteryear:

From Fort Funston. (Now, why did we name an entire fort after that Filipino Killing Cracker?) Anyway, here’s the view, sometimes:

Same angle:

As promised, baby dolphins, avec maman:

And here they are swimming south, off to sample the yummy seafood in the waters off San Mateo County:

And, this is cheating somewhat, a military dolphin near AT&T Park:

Keep a lookout for dolphins!

Some of the Nude Beaches in Marin County Can be a Little Hard to Get to These Days

Thursday, September 2nd, 2010

You’ll have to figure out for yourself just exactly where in Marin County this nude beach is, in this mostly-SFW photo from a while ago. The place was officially closed at the time due to an unsafe stairway and it’s more-than-likely officially closed at this time.

But actually, your nudist types like out-of-the-way places anyway, the kind that require long descents from the nearest road.

Now, your San Francisco Bay Guardian occupies the field of nude beach field scouting – their link appears to be down right now but feel free to give a try later on.  

The nude types were to the east of the stairway and the never-nudes were to the west - it all worked out. All the while, a couple of fun fearless females felt free to parade up and down the whole beach by the low tide line, on the catwalk, they did their little turn on the catwalk, yeah on the catwalk, on the catwalk, yeah, they did a little turn on the catwalk for about half-hour:

By the way, is there a special law that disallows photography on Public Nude Beaches? Not that I’m aware of.
