RE: Eclair Cameras: Shooting 35mm lenses on 16mm camera

[Chris Leong <emotepix@artnet.net>]

Hi Vic

Just completed a pretty wide (although subjective)
lens test between 
rented Zeiss lenses (one 10-100T3, two superspeeds),
regular 16mm lenses 
(Cooke, Switar, Canon TV-16) and 35mm stills camera
lenses on a C mount 
adaptor (Zeiss Oberkirchen for Rollei, Zeiss Jena
and Olympus OM). 

I think I can answer your question since I did the
test two days ago and 
watched the results at Fotokem last night:

I too thought I saw better results from the zoom.
This turned out 
marginally to be the case, because the 35mm stills
lenses are built to 
cover a much larger image area to comparable
sharpness as the smaller 
16mm lenses. However, with top flight stills lenses,
like the Zeiss or 
the Nikkors, that difference is only noticeable at
larger apertures and 
with finer grained film. I shot a variety of stocks
and with anything 
over an EI200 speed film, at larger apertures, the
grain took my 
attention away from the lens sharpness.

At EI50, the results were as one would expect:
first, the Zeiss Primes. 
Then the Zeiss zoom, marginally over the Zeiss
stills lenses at wide 
aperture. (Stopped down is another matter). Then the
older R16 lenses, 
then the cheaper TV-16 zoom.

However, I do plan to use some of the "less sharp"
lenses on certain 
headshots, just because the softness is more
pleasing to the eye and the 
sharpness isn't THAT far off from the Zeisses. 

Just think - a $20 C-mount Canon TV-16 zoom lens can
give (IMHO) a nicer 
headshot than a $1200 Zeiss 10-100 zoom or a $1000
Zeiss Highspeed prime 
(of course, both Zeisses with black net 1's and
lowcons to hold down the 
contrast and soften the face)...

(now if only I can solve the enigma of the fogging
magazine...)

HTH
Cheers
Chris
-much happier now he's made sure that all's as it
should be-
