Zeiss LWZ.3 21-100mm t2.9-3.9 COVERAGE

[Karel Šimůnek]

Hi guys, I have a question regarding Zeiss LWZ.3 21-100mm t2.9-3.9 lens.
Does it cover Dragon 5K and 6K clearly?
I looks like a great lens and I’m thinking about used 6K Dragon MG or new 5K Dragon-X.
Thank you for your info

With 5k you should be okay, the image circle is 31.1 mm

Oh, nice online coverage tool Misha

LW 21-100 Zeiss is perfect with Dragon-X. The problem is with Gemini.

 

[Karel Šimůnek]

Thank you Marc.
Do you have any real world screen with Gemini to see how bad it is?

 

[Marc Pilato]

No, i don’t have real experience with Gemini and the zeiss LW zoom.
I stay with the Dragon in part because of the image circle issue.
This zoom is so good.
I asked to Zeiss and they said there are restrictions with the Gemini sensor.
Perhaps somebody have made a real try.

Not bad on the Red Helium at 8KHD or 8KWS. A little more vignetting at 8kFF.

I can send you pictures if you want to see.

On Gemini format table (instructions of use),it says at 4.5K FF the diagonal is 31.21 mm.
It is 30.91 if 4.5K 2:1 .
As the LW 21-100 Zeiss zoom covers 31.1 mm, Can we conclude this zoom should be ok at 4.5K 2:1 zoom on 21mm?

Hi Olivier, Yes that would be great if you can post in 8K FF, 8K HD and 8K WS on Helium

Thank you

Hi Karel,

Here are 3 pictures with Helium @ 8K :

8K FF : 8192 x 4320

8K WS : 8192 x 3456

8K HD : 7680 x 4320

 

[Karel Šimůnek]

Thank you so much Olivier!That is exactly what I wanted to see
8K HD and WS are completely clean that is nice.
Thank you again for your time and I'm definitelly going to buy LWZ.3 sometime this September.
Thanks
