Wierdcrew, I know you don't want these to be MI's because it may in fact decrease the value but there is no denying that these are MI's because of the short focus throw. That is in all cases the defining difference between MI's and MII's. Optically all Superspeeds are identical! B Speeds as Stuart mentioned are different but not technically super speeds. These are fine lenses and you should fetch a fine price but please label them properly.
i am not sure how precise this list is - i used "print screen" method to capture this, and unfortunately cannot say where from it was. (i took that a few months ago)

Dear Bob,
yes and no.
There's a small confusion about the B speeds being Mk I's yes, but make no mistakes that these are MK II's - in that there's no confusion.
Followin facts are taken from Cinematechnics website about Mk I, II and III sets.
The Bayonet mount, with its troublesome pin and lockring attachment was replaced with a large and stable lens mount held by eight M2 screws. On the 35mm Mk. II lenses, only the 54mm O.D. ARRI PL mount can be fitted.
Mine have 8 eight screws in the mount
Super 35mm T1.3 Mk.2 set: 18, 25, 35, 50, 85mm, all f1.2 / T1.3. PL mount only. Original Mk. I T1.4 Super Speed prime lenses for Super 35mm cinematography.
The differences in maximum aperture can be easily seen here. The 18, 25 and 35mm lenses are f1.2, the 50mm is f1.3 and the 85mm f1.4.
All of mine are f1.2
A major problem with the Mk. I S16 and S35 sets is the very limited focus marks on the scale ring, combined with the minimal depth of field at T1.3. This meant that eye focus was the only way to go with the Mk. I lenses. The camera assistant had hardly anything else to work with.
Not a problem on mine
The Mk. II focus scales are calibrated in feet and meters. On S16mm and early version S35mm Mk. II lenses, the scale rotates 170º and each side of the lens has one calibration, ether feet or meters.
Mine happens to be an early version
A later version of the Mk. II S35mm lenses has a "wrap around" focus scale with about 350º rotation. These scales have meters on the front side of the focus gear and feet on the back side, with both scales reading from the same index position.
As you can see it's only later versions that has that.
The much larger diameter of the focus helix thread and the larger linear guides reduce play in the focus mechanism and give a much smoother and more consistent focus feel. The guides are also adjustable on the Mk. II.
I can tell you that is the case and you can see that on the pics, but this is something a lens technician can verify and have.
Oddly, the S35mm Mk. II lenses switched from the 9-blade triangular iris to a 7-blade iris. The S16mm Mk. II lenses switched from 6-blade hexagonal to a 9-blade triangular iris just like the Mk. I S35mm set.
Mine are 7 blade iris as you can see in one of the pics. I also stated earlier that this IS NOT the triangular iris
The aperture closes down to T16 rather than T11 of the Mk. I lenses.
All of my lenses are T16
Now do I have to spell this out anymore or can we leave this behind and just agree that these are in fact Mk II's?
i am not sure how precise this list is - i used "print screen" method to capture this, and unfortunately cannot say where from it was. (i took that a few months ago)

It looks like the one from cinematechnic website
Yes and all my lenses are T1.3, f1.2 - which means Mk II. According to that list.
Now I can not speak for Evin and Hollywood rentals, maybe that's right, but these are as far as I know an early version of MK II's.
Now that can maybe be considered Mk I's in Hollywood, but they're not that outside of Hollywood.
Here's the deal...
There is no hard and fast rule about what series these early Speeds fall into. In general my experience from Hollywood rental houses and professional lens technicians is this...
B Speeds: T1.4, 9 blade iris (Triangular), no built on gears, Bayonet mount
Mark I Speeds: T1.3, 7 blade iris, built in focus gear 170º focus throw Bayonet or PL mount
Mark II Speeds: T1.3, 7 blade iris, built in focus gear 340º focus throw PL only
Mark II Speeds: T1.3, 7 blade iris, built in focus and iris gear 340º focus throw PL only focus scale on both sides
I'll concede that this really is a grey area but my call is Mark I.
I sense an internationl crisis arising....
Germany, Norway, Denmark vs the rest... now wheres sweden when we need ´em...
