  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Does anyone have any answers on the Leica Summicron-C’s covering 8KFF?

The 100 and 135mm are the only two that cover RED VV at 8K FF. 65mm and 75mm handle 6.5K FF.

For the atypical Underwater and Natural History shooters

MONSTRO 8K VV:

NIKONOS RS 13mm Fish Eye:
~ Nikon Mount (Gates Custom)
• Vignettes mildly on the smaller 8K formats
• Vignettes heavily from 8K HD to FF
• Covers up to 7K FF


CN20x50 IAS H (aka 50-1000mm):
~ PL Mount
A) No extender (1.0x) – Full zoom range (50-1,000mm)
• Vignettes extremely in any 8K format
• Vignettes badly in any 7K
• Vignettes faintly from 6K HD to FF
• Covers everything up to 6K 3:2

B) No extender (1.0x) – Higher zoom range (+/-400-1,000mm)
• Covers fairly well (sometimes a very vague vignetting) on all resolutions
• Unless you need every candela available on every photon, I wouldn't use it with dynamic subjects

C) With built-in 1.5x extender engaged (75-1,500mm)
• Covers the full range...
• On every resolution...
• Mind blown (but very happy :willy_nilly: )

More tests to do with 'odd lenses'

Would be interesting if anyone has tried the Canon 50-1000 on Gemini. If it has vignetting on 6k Monstro that means it should vignette at Gemini as well which is a bit of a shame.

Hi Andreas, sorry I couldn't reply earlier. Too busy preparing for an Arctic expedition (with the CN20x50 aka Canon 50-1000).
Don't try to figure out the coverage of the CN; it makes no sense.
That lens has completely different "optical laws" as other lenses (a very weird one).

Keep in mind this lens is a certified 4K lens only. Every 'K' above that, to me, is a blessing.
I can't test it now as it's already packed and configed for MONSTRO, but I'm pretty confident it will cover the entire range of 5K Gemini formats.
Mind you: I'm not an optical engineer nor do I have a Gemini. This is just my gut feeling.

That said: it is a BEAST of a lens, I'm addicted to it! If your type of shoot allows for this lens, it's 'the one and only'.
My personal 5c.
Cheers,
 
Hiya Michael. That sounds like an awesome expedition! Please show what you have been up to when you are back. Just came back from stormy Puffin filming, but Arctic sounds even better!

What would you pick for wildlife? A Helium or a Gemini? Either you have the 8k from Helium or the low light abilities of Gemini. Gemini adds 2 stops which is a lot when it is getting darker. I often find myself that I need a higher ISO when it is more cloudy because I need to shot in slow motion. That makes me lean more towards the Gemini.

No worries about tests. I'm setting up a demo with both camera and lens a few weeks from now so I will test it very carefully. We love our 600 F4 IS lenses, but it is becoming more and more limiting to not have a zoom so yes the 50-1000 seems like the golden ticket.

Thanks for the advice and have a wonderful journey!

Arri Zeiss Master Macro 100mm covers 8k FF on Monstro. Was working with this lens the last couple of days. This came as a surprise to me as PHFX tools stats it is only covering 5.5k

Hi Andreas,

It's not as simple as "one or the other". Wildlife covers a lot: the entire planet, oceans and air.
To talk about the Arctic alone: ideally (in the RED environment) you would need a MONSTRO, a HELIUM and a GEMINI exposure-wise.
This with (E)WS and MS in mind.
In the High Arctic the light changes (season-wise) so incredibly quick; you could have a specific shoot of one subject over 3-4 weeks having to start with Gemini, switch to Helium and end with Monstro. All in 3-4 weeks time.
This is theoretical and merely to point out there is no right-or-wrong answer to your question.

It's somewhat the same as asking if RED is the best camera to have. Arguably they are but.... to me the best camera is the one you have at hand when you need it :)
Cheers,
 
Phil, hope all is well.
Thanks again for sharing all those infos and knowledge.
I have a question regarding the Zeiss CZ2.
According to the charts in your first post here, the 15-30mm covers 8K FF starting at 17mm and the 22-80mm covers 8K all the way.
But when looking at the results on your lens data apps, both only cover 7,5K on Monstro.
If possible I’d like to know why there is a difference between both results?
 
I'm testing a monstro here so will have chance to test coverage of a bunch of lenses. Some lenses we have access to are most Canon DSLR, but also Canon cine zooms like 30-300 and 50-1000.
Best wishes,
Andreas
 
Just tested some Sigma Art lenses.

Sigma 35mm f1.4
Vignettest quite strongly at 8k FF. Could still be usable for a brighter scene if one compensates for this in post
7k. Softer vignetting but still noticeable. 7k HD even better. I would feel ok filming with this
6k. Just a very tiny darkening in the corners that you can barely see, mainly at f1.4.

Sigma 135mm f1.8
No vignetting at all. The image is just awesome. Very nice to film with.

Canon 30-300 T2.9
Did not have time to test the 30-300 but I would expect it to vignette very strongly, it has already strong vignetting with Helium, worse than 50-1000mm.
 
For wildlife cinematographers in need of a manageable long throw lens: this is a small demo I share with you to demonstrate the capabilities of the Canon CN20x50 IAS H P1 lens (50-1500mm).
This is just the optical zoom of the lens (with 1.5x) going from 75mm to 1500mm. There is no cropping, digital zooming or stabilizing done in post. For me it's my perfect HNU lens for the High Arctic.
Shot on RED Helium in 8K FF without filters (Std OLPF).
Although Monstro would be a better choice for this scene (cinematographic), I preferred the Helium because it has very little vignetting on the CN20x50 (none with the convertor, some without).
HTH.
