Zeiss 10-100mm T3 T* Quality and coverage

[JCorben]

Hello, please I'm searching information about this zeiss zoom: 10-100mm 2.8 T3 T* coatin version.

 

1. I heard that is better than the non coating version but, how much much sharper is than other zooms (Angenieux...)?? The money difference with 10-100 T2 is high... Does the difference in money worth?

 

2. I heard too that the 10-100 NOT T* (the older version) not covers Super16 frame at all,

This is true for the T* coated 10-100 T3 too?? I'm confusing with the T3.0 coverage and the T3.3..

 

Thank you for read me...

More thanks again if you can help me.

Jose,

 

All those lenses are decades old, so it is difficult to say how good one is compared to another as much of it comes down to individual lenses and what condition they are in. To get a general idea of the different lenses, you can take a look at the web site below that shows clips shot with the Zeiss 10-100 T* T3.1 lens, the Angenieux 12-120 T2.2 lens, and the Zeiss 10-100 T2 lens.

 

Lens Comparison

 

But again, that test shows the difference between the three lenses I happen to have for that test, not all Zeiss and Angenieux lenses will be the same.

 

As a rule of thumb, the Angenieux 12-120 T2.2 lens is the lowest quality as far as sharpness goes, though I have seen one from time to time that was very sharp. The next step up in quality was the Zeiss 10-100 T3.1 without the T* coating. The next step up in quality was the Zeiss 10-100 T3.1 with the T* coating. And the best quality lens of the ones you listed above is the Zeiss 10-100 T2 lens.

 

None of the lenses listed here will cover Super 16. The Zeiss lenses will vignette below about 32mm on the zoom scale, and I am not sure how badly the Angenieux will vignette, but I know it will not cover the Super 16 frame. There is a conversion for the Zeiss 10-100 T2 lens that converts it to a 12-120 T2.4 lens and the converted lens will cover Super 16. There used to be a conversion for the Zeiss 10-100 T3.1 lenses, but I do not believe it is made anymore. And I do not know of a conversion for the Angenieux lens.

 

Hope that helps,

-Tim

It's sharper than the Angenieux zooms of the period. The main advantage the T2 10-100 has over the T3 is the speed difference, I wouldn't say there's much overall difference in the sharpness once stopped down (at least with the lenses I owned). You used to be able to get a rear adapter to convert the T3 to Super 16, just as you can the T2, although you're losing more light on an already slow lens. You might be able to use the unmodified T3 at longer focal lengths on Super 16, I've never tried it

 

The triangular flare is a characteristic of the T3. However, I rather liked that you could focus down to a metre at 10mm without vignetting, whereas on the T2 you were limited to 5ft. Both lenses breathe when focusing.

Thank you very much for your informations Tim and Brian!

 

I saw your footage examples and your web long time ago, Tim. I think it's a really good info for begginers like me.. congratulations.

I own a T2 Mark II and it a great lens with pros and cons. The Mark 2 T2 had a larger front element at 87mm. I think the T3 had an 80mm so vignetting was more of a problem. I am not sure if the first version of the T2 had an 80 or 87mm front element.

 

But as a work horse lens the Mark 2 T2 is a great all around lens to use covering a wide range of zoom. However its weakest points are the breathing, vignetting when focused under 5 feet at 10mm, and it's close focus distances. Now the barrel's shortest hatch mark says 5 feet, but you can focus under 5 feet to maybe 3 or 3.5 and vignetting is only a problem at the wider end of the lens. One feature that does try and make up for the longish close focus issue is that it has a macro feature where one can easily shoot the label or a prescription bottle for example.

 

And just for clarification the lens is really a T1.8 not a T2 so one can get a little more out of it.

 

I would stay away from the T3 versions and try to get a Mark II T1.8 if you can.

 

Someone was doing a Super 16 upgrade of this lens making it a 12 to 120 T 2.2 I recall but I think that was Optex and they went out of business. I don't know if someone else is doing so.

Hi Tim,

 

I'm pretty sure the Zeiss you're talking about actually is a T2. It is a little confusing because the lens is marked on the front with 1.8, which is the f-stop. I believe the difference is that the f-stop number represents light transmission based on the optical formula; the t-stop is the actual light transmitted. The Zeiss 10-100 t3 is marked on the front as an f2.8 lens but only opens to t3.1 on the aperture ring. Another example are the Zeiss Super Speeds which are marked f1.2 but only open to t1.3 on the aperture ring.

I had a Mark 1 T2, which had a 80mm front, the T3 had a step up ring for my 80 mm 3" x3" L/W clip on matte box and from memory it could be 75mm (or 72mm).

 

I don't recall any noticeable vignetting on my T3, but it was the first thing you noticed on the Mark 1 T2.

 

 

Abakus now directly supply the Super 16 converters.

Hey Fran,

 

It seems as though the hash mark always goes slightly past the 2 when I try and open up all the way so I always assumed that point was 1.8. It doesn't go all the way past the number 2, but goes just past the center of the printed 2. That is why I thought I had 1.8 available.

Good point, Tim. Most of the cine lenses I have do the same thing. My Super Speeds will open past the 1.3 mark, but I don't know if they actually gather any more light beyond the maximum marked aperture. I know most lenses will also focus past the infinity mark. I've been told this is to allow for slight mechanical variances in the hardware that might otherwise prevent infinity focus.

does anyone know if these lenses work on ARRI ST? with bayonet fitting? 
It says ONLY FOR ARRI SR on the back of the lens...

thanks!

[Brian Drysdale]

There is a plunger type device for the internal light meter on the SR, which would probably need to be deactivated at the back of the lens. I used my Zeiss zooms with an Arri bayonet adapter onto an Aaton and a CP16, but unless there's a clearance issue with the Arri ST mirror, it should fit with a mod.
