I have been getting conflicting advice on whether the full
complement of Arri Ultra Primes will fit an Arri 3 mk2 that
has been modified (Panavision) to Super 35 PL mount? We have
physically mounted the lenses and gently hand turned the shutter
with seemingly no contact but I have been advised by experienced
technicians I am asking for trouble especially with the rear
clearance on some of the wides.
The Super 35 modified Arri 3 has real limitations with certain
lenses rear clearance and that is well documented but as yet
I cannot find definitive data on the Ultra Primes. Has anyone
been here ?
Another anomaly to be aware of is that the extreme rear of
some lenses can block the path of the shutter reflected image
reaching the ground glass. Therefore it appears you are vignetting
in the super 35 territory as far as viewing is concerned while
you are in fact covering on film.
If this issue has already been covered forgive my repeating

T 1.3 primes offer no problem. T2.1 primes are generally a
problem wider than a 50mm. I recall a list of all problematic
lenses in the CML Archives that I downloaded.
I'm on location, but will give you more info when I'm home
by the weekend.
The biggest problem is the viewing system. The camera was
never designed with the super 35 offset in mind. Sometimes
you cannot see edge to edge in the reflex system, depending
upon focal length /lens manufacturer. The wider lenses are

There's also a little known issue with S-35 Arri 35III shutter
counter weights(only on the variable shutter models) I believe
there's a slight blur on the edge of the frame as a result,
not easily perceived.
I can't answer the question of Ultra Primes and Super 35 Arri
3 cameras, but I do have a variety of useful information on
There are a number of conversions possible. We do a conversion
where we add a new Super/Standard lens mount, and a new ground
glass holder & ground glass, and modify the viewfinder
(Jurgens works well) to reasonably see the Super image area.
Some of the issues to consider are: Zeiss Standard Speed lenses
wider than 28mm may impact the mirror shutter. I'm not in
the office to confirm, but I think the 14mm may be OK. This
means that the 28, 24, 20, and 16 don't work. 18, 25, and
all longer lenses are OK. The 12 is out as it is a modified
16. I don't have the info on the 10 here.
Also, most zoom lenses are out, not because they impact the
shutter, but because they vignette!
If anyone is interested in more definitive information on
our conversion and what lenses do and don't work, please contact

Speaking of viewing issues some video doors for S-35 Arri
III's don't cover entire frame. I believe the left side of
the frame is slightly cut by commonly used Jurgen's video
doors due to slight enlargement of GG image in door optics.
Straight doors and held doors do not seem to have this problem.

Andre Martin at Clairmont (and I'm sure others do as well)
builds an optical "reducer" that allows you to see
full frame S35. It's magnetic, so you can switch between centred
academy and Super 35.
