In the late 60's & early 70's, I shot alot of F1 & Can Am cars at Moss's
corner - hand held with high speed ektachrome, sometimes pushed, with a
Spotmatic and a 200 or 300 mm Takumar lens, pre focused, and was lucky if I
got 6 keepers out of a roll of 36!

Subject: Re: PESO Red means go
The cars were hauling ass coming straight toward me entering the
hairpin turn then heading camera-left. These two cars were likely
about 3-4 car lengths apart so the lead car was already heading left
fast while the trailing car was still pointed straight toward me.
My shutter speed was kinda low: 1/160th. My back-of-envelope estimate
suggests that at 1/160th of a second, the lead car would move about
2.5 cm if it was going about 30 Km/h relative to me at 45 degrees into
that turn. If the lateral smearing of the license plate is to be
believed, that agrees and is about right.
I was lucky to have anything in focus at all. I had no tripod or
monopod, too low shutter speed, and there wasn't anything obvious to
manually focus on at that low angle parallel to the road surface. I
braced the hood against the chain link fence for stability and
focussed on what I hoped were tire marks in the middle of the track. I
should have maintained the shutter at 1/250th or faster to stop the
lateral movement I think. I could have traded-off higher ISO to get
that.
My entire catch was comprised of near-misses I think.
Glad you found it interesting, Paul! :-)

Nice framing and exposure. However, the second car appears sharper than
the lead. A variation in motion blur perhaps? the track seems to be in
focus in the foreground.. That's a bit odd. Focusing on a car behind the
lead sometimes works if that car is worthy of highlighting and the lead
car is more obviously out of focus, but you don't quite achieve that
here. Nevetheless, an interesting photo.

I haven't pixel-peeped any hi-rez images for sharpness yet, but they
look reasonable so far. The lens is light and quick and easy handling.
The 2:1 zoomed-out length was an issue when I was stabilizing it using
its hood against the chain-link fence, but that's minor. (I'm used to
the internal zooming of the DA* 50-135.) AF was fast on well-lit
stuff, but it did the crazy near/far see-saw thing when I tried to
focus on something in the shade.
It's rather slow too (f4 - f5.8) and I don't do a lot of outdoor
shooting these days, but that said, I did enquire from its owner if he
was considering selling it. :-)
Thanks, Dave!

Nice colours and sharpness on the follow car.
Impressions of the DA F 55-300 ??? I'm Still debating on getting it.

I was invited by my K-5 shooting friend Gerrit Visser to spectate
during "Ferrari Day" at the Canadian Tire Motor Sport Park (aka
Mosport) Monday. Gerrit also loaned me his disused DA 55-300 as I
don't have any long glass to speak of, besides my DA 50-200.
The Ontario branch of the Ferrari Club of America books the track for
the day and members bring their own wheels to test on it. Here's one
decent shot I got where a couple of classic cars are entering Moss
Corner, the hairpin comprised of turns 5a and 5b.

It's really hard to get an unobstructed sight-line here because of
multiple safety fences. We asked a track official if we could get
closer. After determining that we'd both signed the If You Get Killed
By Flying Car Parts You Can't Sue Us waiver, he said sure. "Just be on
your toes because that's a strike zone."
I was able to shoot through the closest chain link fence with the DA
55-300mm to get some nice low angles like this one. This is uncropped,
btw.
