EF 300 4L USM
Petite Great White
The EF 300 4L
USM is my only great white lens and my
largest optic. I bought it used in 1995 and it endured hard tours of duty shooting sunsets, candids and surfing at Waikiki and Ala Moana. I lost interest in telephotos and the 300 4L languished in my cupboard for ten years. I recently pulled it out and, after a few initial zips and bumps, found it as sharp and fast focusing as it ever was.

It's a beefy hunk 'o
glass with burly metal barrel but balances well on larger EOS DSLRs. You don't want to drop this puppy on
your foot. The 77 mm filter size makes filters
expensive, but I rarely use filters on
telephotos. Finally, the slide out hood is handy, especially since it's attached to the lens and can't be misplaced.
large lenses, lift the rig by the lens, not the
camera, or you may stress the camera's lens
mount. It's also a good idea to not use a
shoulder strap on the camera. Instead, put the
strap on the lens or use a bag. A few pounds of
metal and glass bouncing up and down all day
isn't good for your camera's lens mount or

focusing insures that the front element does not
rotate and barrel length remains constant. AF
rips due to silent ring-type USM and rear focus
design. It has an AF distance limiter, but I've
found it unnecessary as AF is accurate
and rarely hunts on the cameras I've owned.
Like all ring-type USM lenses, it has
FT-M and a distance window. The manual focusing
ring is wide, grippy and turns almost as
smooth as manual lenses of
yesteryear. My main complaint is that it only
focuses down to 2.5m, close enough for head and
shoulder shots, but not close enough for small
mammals and birds.

I can hand hold this lens with consistent
results if I brace myself against something or
sit down. However, it's at its best on a tripod or monopod. The
detachable tripod mount takes the weight and
stress off the camera and allows a rapid
transition from horizontal to vertical framing.
Unfortunately, the jumbo size and off-white
finish attract attention, so it's
difficult to use when stealth is
After years of laying dormant in my cupboard, I mounted the EF 300 4L USM on a 5D MKII and walked out the door. Initial images were soft although I recall it being silly sharp on my 10D/20D and film cameras. I checked the AF Microadjustment (AFMA) menu and it was set to +5 for this lens. I did a session with a focus target and it was pin sharp with AFMA calibration set to -2. Not sure how it got set to +5 but all is well now!
With the new AFMA calibration I found this
eight-element design to be razor sharp,
contrasty and reasonably flare resistant. In the 1990s, I shot thousands of blazing Hawaiian sunsets with this lens using film there was little or no flare and zero ghosting (internal reflections). My "Runner at Sunset"
image is a testimony to the EF 300 4 L USM's
amazing resistance to flare when using film. Most zooms have ghosting problems
with shots like this, usually several mirror
images of the sun in the frame (I remove
filters before shooting sunsets).
Oddly, on the 5D MKII, there's a modest amount of flare and ghosting with bright sunsets. The ghosting puzzled me since it never happened with film or APS-C (1.6X) cameras and wasn't visible in the viewfinder. The 5D MKII's large CMOS sensor is shinny and I suspect is reflecting the sun's disk back to the rear element.
The EF 300 4L USM shipped with Tripod Mount Ring A (white, #2889A002).
A collar makes tripod
use easier, especially verticals, and prevents the weight of the lens from stressing the lens mount. If your lens is missing the tripod collar (mine was), you can save a few bucks by
purchasing the Tripod Mount Ring A (black,
#2888A002). It's the same as Tripod
Collar "A" (white) except for the black
finish. The tripod collars are
interchangeable between the EF70-200 4L USM,
EF80-200 2.8L, EF200 2.8L USM, EF300 4L USM
and EF400 5.6L USM. The Tripod Mount Ring B
will not fit. If you're on a tight budget, there are Chinese Tripod Mount Ring A clones galore on Ebay.
I often use the EF 300 4L USM with the Extender 1.4x (original) and it gives up little in terms of sharpness. At 420mm and F5.6 it's not a hand holding combo for me and I need a beanbag or tripod to render sharp images. The Extender
1.4x didn't flare any more than the bare lens,
even with a blazing Hawaiian sun in the frame.

The EF 300 4L USM was discontinued in the late 1990s and replaced with the EF 300 4L IS USM. What that means in 2016 is there are few parts for the EF 300 4L USM and Canon no longer services it (independent shop may). Also, DPP lacks a lens profile and, thus, digital optimization isn't available for images taken with this lens.

Although the "old man" of my lens cupboard, the EF 300 4L
USM holds its own against newer optics: tough, fast focusing and amazing image quality. For outdoor sports, landscapes and candids this lens
deliverers quality without breaking the bank and can take more knocks than typical plastic 75-300 zooms. Used EF 300 4L USM go for
$400-700 depending on condition. If you find
yourself mainly using the long end of a 75-300
telezoom, the EF 300 4L USM may be for you.
