PRODUCT EVALUATIONS

Canon's

Model VM-El continued

.. .

Grayscale

trace shows some sag and

its

top is exaggerated, but

this was not more

than was expected.

R-f unit has a

vhf output and separate

video

/audio inputs and outputs.

Audio reproduction

pecially smooth

kHz usable frequency response.

especially in poorly

illuminated indoor

scenes. The

Canon

falls more

into the lat-

ter

category.

The model's macro

function is

surely a

competent performer. With

it, it is

easy

get sharp closeups

to as near as '/,

6 r',

all

while

watching through

the

viewfinder.

It's

a great feature to have

if you're a

stamp or coin

collector, or a flower or in-

sect enthusiast.

In our judgement,

the

-El and

ac-

cessory

-kit

combination is quality mer-

chandise

competitive

price. It's good

equipment all the

way.

-Stan Prentiss.

Counterpoint

C'mon Stan. How

may

$1,700 buyers

are out there

who

are "live" recordists?

Yes, this is a competitive price, but,

hopefully, there

will

lots

more com-

petitors coming up

who will

drive

the

price

down.

On top

this, the model does not ap-

pear to be an all

-round

great

performer,

based on

the

"trade- offs" you yourself

cited.

And

I don't get digital

hi -fi

stereo

sound so that one can use

the

camcorder

a good stereo

/high -fidelity deck, or a

timer,

nor are there special effects

func-

tions available.

Furthermore, why didn't you men-

tion

the octopus

of wires

and con-

trivance that must

attached

the

camcorder

in order to make it

"home"

unit after schlepping

around

and

using it on battery power? Just

think: you need Canon's CA -El

com-

pact

power adapter that

has

to be plug-

ged

into

power

outlet, its RU -El

unit that has to connect between

and

the camcorder, another

-El

line

(VHF Out) to connect to

separate

Canon antenna selector,

and two more

connection

lines from the

selector

that

goes

to the

standard TV set's

VHF input

and to the antenna

(with

300

-ohm to

-ohm

adapter,

to boot). Then

add a

wired remote

-control

line

and you've

likely missed

whatever

you might have

wished to record from

TV in the first

place.

Anyone going through the foregoing

hookup

hassle for a non -permanent

setup,

which

a portable unit like this

camcorder has to

be considered,

would

have to spring for an 8 -mm playback

deck to avoid

all, as well as buy some

costly accessories.

A permanently

con-

nected

"cradle"

would

much better.

conclusion

is not quite

as en-

thusiastically positive

as yours, though

the model is nice

enough.

I think it's too

much (cost) for not quite enough in

terms of performance and built -in

func-

tions (primarily

digital

sound).
