maker

Canon

U.S.A.

has

added

an 8 -mm

camcorder to its video-

cassette portable line,

joining

a growing

number

of manufacturers

entering

models

with

this format.

Canon's new Model VM

-El is

lux-

ury

-class

unit that has virtually

every-

thing

one could

want

in a portable VCR

you include

few

of its options. The

cam-

corder weighs in

4.4

lbs

without

battery

and

measures

moderate 5%

selling

price

is a heavy

$1500,

though, with

an added

$200 for

an accessory kit that includes

power

adapter, audio /video

-f play-

back

adapter, as

well

as an optional re-

more- control unit and other items.

The

Goodies

The VM

-E1's sections

are easily assem-

bled (and disassembled).

That is, the

main

body

has

a mounting

shoe that

holds

an electronic

viewfinder,

ac-

cessory

shoe for mounting

a carrying han-

dle and neat "rails"

at the rear of the

unit

to accommodate

a choice of two Canon

battery packs.

Equipped with

and

there is not

else one could

want

in terms

of the

end of the unit.

course, focus is automatic

(defeatable).

In keeping with

Canon's camera -mak-

ing heritage, this is really

a "system"

whén

one considers some options: wide

angle and telephoto converters to go

beyond its

8.5 -51

mm focal length,

filter

sets, a character generator, shoulder

brace, microphone boom,

car

battery

adapter, chest pod, system

carrying case,

and

the like.

The built -in electronic

viewer

provides

a 0.7

black- and -white playback picture

for viewing live recordings

and prere-

corded tapes while being used as a port-

able. An electret unidirectional mic is lo-

cated at one end, while the viewer is lo-

cated at the opposite end

with

an eyecup

and

diopter

adjustment

ring for the user's

convenience.

Most of the controls are on the left

side

of the camera body. On the

right

side

there is

a single

stop -start button and the

x zoom lens T/W controls for two

fingers and the thumb to manipulate.

In addition to having automatic

focus,

well

as being able to switch to

manual

you wish to, there is a "one- shot" focus

setting in the

manual mode

that will lock

in the focus

automatically

for you

and

not

change should a

large

object (say, a per-

son) suddenly

cross in front of

the

view-

ing

area.

Furthermore, white balance is auto-

matic and held in memory for an hour or

so. There's

memory

button,

too, that

will

enable

one

to automatically go to a

selected portion of the tape, as well as

fade in -fade out control of both picture

and sound. It can be used for

three

-sec-

ond fade.

To its features add an LCD window

that displays all operating functions be-

ing

used,

model.

Lab Testing

Laboratory tests tell a

lot

about the new

Canon 8 -mm model, though not

all, of

course.

With

charts developing

standard

signals as defined by the Electronic In-

dustries Association (EIA), Tektronix

and Hale Charts,

analysis by the

numbers

should be quite accurate, though.

As the

photogragphs published here

show, the Canon's high- frequency

re-

sponse is excellent,

extending

least

MHz. This is

better than many VHS

and

Beta VCRs.

[Why Canon specs the model

at 300

lines

with a parenthetical "camera

section," which is very roughly

3.75

MHz, makes

one

wonder. -Ed.]

Equally

fine is its measured 400

lines of

vertical

resolution,

measured

on Tektronix'

circular

chart.

However,

Tektronix' I and Q

chroma

evaluation

chart,

which

excites colors be-

tween 400

and 800 kHz (depending

partial

chart exposure) did not produce

exceptional lavenders

or deep blues.

Moreover, the Hale color

chart,

with

its

three NTSC primaries

and complements,

wasn't well represented

in yellows

and

reds. Following this, the

crossed ban-

dolier of 9 gray

-scale steps sags

the

mid-

dle,

while

the upper portion has more

amplitude than the lower portion.

Sensitivity was fine
