The Canon EF 70-210 f/4 "One-Touch" Zoom Lens Works GREAT On Canon EOS Digital SLRs

Maybe I am just an "old fogie", but often I wonder; What ever happened to those super fast zooming "one touch" Canon lenses of yesteryear?
Modern zoom lens design has completely shifted to the "two touch" or
"twist" style zooms, while the venerable "one-touch" models have been
all but forgotten. Am I all alone here, or are there other photogs out
there who miss the speed and accuracy of a good "push-pull" zoom lens?


Back in the days of Canon FD mount manual focus lenses; the "one touch" was king. We could zoom AND focus simultaneously.
It was extremely easy to frame a shot and find the perfect focus point,
all in one completely natural motion. We were able to get some very
interesting "artistic" effects by zooming and adjusting the focus,
while the shutter was open, to create some really interesting images.


When Canon introduced the EOS system in 1987, we were
treated to a new selection of "one touch" EF mount zooms, but they all
had the added magical feature of full auto-focus mode. This
seemed to be the absolute best of both worlds. Making the transition to
the new EOS camera felt comfortably familiar while opening us up the
convenience of fully automated focusing. Then, one-by-one, all of the
"one touch" models were discontinued, unceremoniously replaced by the
"modern" rotating zoom models. These were, and are, some great new
lenses, but somehow we never quite forgot how naturally and quickly the
older lenses responded to our every command.


Now, we skip ahead about 20 years and we find ourselves in a brand new "Digital" world. The "one touch" lens is all but a distant memory. Except for one thing, THE EARLIER EF SERIES "ONE TOUCH" LENSES WORK GREAT ON THE NEW DIGITAL SLR BODIES!
I resurrected my "antique" Canon EF 70-210mm f/4 Macro from the closet,
locked it on to the EOS 10D and quickly discovered that old familiar
magic again. WOW, that lens has great optics! With a respectable
constant aperture of 1:4 (just like the new EF 70-200mm f/4L) and with
that slick action sliding zoom mechanism, I was back to creating the
types of shots that I had loved so many years ago.

On the technical side, the
Canon EF 70-210mm f/4 MACRO is constructed with 11 lens elements
arranged in 8 groups using "Super Spectra" coatings. It accepts the
most common and affordable 58mm filters and accessories. The AFD (Arc
Form Drive) auto-focus system is not as fast or quite as the USM drive,
but it is plenty quick enough for most applications, including sports.
However, I usually use this model in manual focus mode because of the
effortlessness of the combined zooming and focusing action. That is
what attracted me to this "old timer" in the first place.This model features an outstanding
