Arri UWZ 9.5mm-18mm T2.9

Having a play with this extraordinary lens.

It's completely rectilinear even at 9.5mm, no distortion, no breathing and sharp as a tack.

As none of the usual wide-angle visual cues are present in its 'look' the visual effect is startling. A subject up-close to the lens looks flat and undistorted... as if shot on a much longer focal length.


It will cover a image circle of 34.5mm, so no problem with coverage on the Epic's 6K sensor... all the wider on the 9.5mm end too.
Its physically fairly big, 335.5mm from mount to front. It also flips the image upside-down by 180 degrees. Both of which suggest that Arri has employed some fairly unconventional optics to make it all work.
Cant wait to use it.

Symmetry

Just completed what has been an extraordinary month of filming. A month of exacting, balanced, and largely symmetrical composition and camera movement.
Photographic symmetry has long been used by film makers to denote order, to foreground systems or patterns, to highlight cinematic artifice, or to underline the geometry of context. 







And to move the camera within the axis of symmetry requires Grip. This is not a style of framing given to verite camera work, but rather a more steady fluidity. Precise tracking shots, gliding slider movement and controlled jib moves. 















 We also made use of the Satellite Crane, courtesy of its inventor Tony Hill. Its a crane arm which rotates precisely/optically 180 degrees around a fixed point. Camera movement as a sort of rotational symmetry... its effects quite hypnotic.







A compelling visual journey, helmed by director Luke Wiles.

50mm chart comparison: Luma Tech Illumina (Mk2), Cooke S4, Zeiss Ultra Prime, Zeiss Super Speed (Mk3)


Although there is far more to a lens than shooting resolution charts, these tests are helpful for looking at certain performance characteristics. I charts below are from four spherical 50mm lenses, shot first clean and then with lens flare. The flare was provided by a fairly aggressive Dedo spot-light hitting the lens from the left of the chart.

All lenses were first shot wide open, and then again when stopped down to T2.8

Luma Tech Illumina Mk2 50mm T1.3

Luma Tech Illumina Mk2 50mm T2.8


Cooke S4 50mm T2



Cooke S4 50mm T2.8


Arri/Zeiss Ultra Prime 50mm T1.9 


Arri/Zeiss Ultra Prime 50mm T2.8


Zeiss Super Speed Mk3 50mm T1.3


Zeiss Super Speed Mk3 50mm T2.8



I was surprised by the noticeable difference in sharpness and contrast between the two T1.3 lenses. The Super Speed was far softer than the Illumina wide open. Perhaps one might expect this in lenses built 30 years apart, but the lack of resolution was striking. The Super Speed's contrast 'smearing' wide open (particularly evident in the far left of the grey scale (0.2 grey) was a bit more alarming.

The resolution impact of the lens flare was most evident in the Illumina, whilst the Ultra Prime fared best under the flare. I have always liked the Ultra Primes' contrast performance under flares... and unlike the un-flareable Master Primes the UP do still flare dramatically whilst retaining contrast. Although I have used the Illuminas for spectacular lens flares, its always at a heavy cost to the rest of the picture.

Although the Cooke S4 and the UP do not reach to T1.3, by time all of the lenses were stopped down to T2.8 you do begin to see why these two are the more premium choices. At T2.8 the UP and Cooke out-perform the faster lenses. 
Both the UP and S4 also deliver a far more 'useable' image wide open than the Super Speed. Albeit at a slower stop, they deliver a far more acceptable photographic result.
The Illumina fares better at T1.3 than the Super Speed, but then the addition of the flare is most noticeable in the Russian glass which seems to have almost no flare suppression.

Overall, for the purposes of this test, I would say the Ultra Prime 50mm fared the best. Given that I would need to stop down a half stop on the Super Speeds to get a more useable lens, it would always be preferable to shoot wide open on an Ultra Prime.

On Super Speeds in the States


A weeks shooting across LA and Seattle with two different sets of Zeiss Super Speed Mk2s.



It is interesting how these lenses, now 30 years old, still attract so much attention. A set now costs more than it did back in the 80s, when production ceased. The two sets I used both seemed to cover 5k on an MXEpic... With some slight vignette ( or maybe 'port holing'?) on the 18mm.

                            

The regular set is the 18mm, 25mm, 35mm, 50mm and 85mm, these all F1.2/T1.3
And its at this stop is where the lenses are the most interesting, yielding soft, diffused shallowness. Don't look too closely though, as these 30 year old aspheric lenses do exhibit a fair bit of chromatic fringing and some spectral distortion. Good for portraits, but you wouldn't want to shoot a pack-shot on them wide open, particularly when close- focused.
By 2.8 they are radically different lenses... And herein lies their problem. These lenses look quite different at different apertures (something Zeiss addressed in their Ultra and Master Primes) By T5.6 they offer an overly sharp/zingy look in no way resembling the softness of the T1.3

Their age is also an issue for their optics and mechanics. Zeiss will no longer service or supply parts, so lots of wear on the helical screws ( meaning one of my 18mm was too tight to follow focus) and inevitable scratches and compromised coatings on the optics. The focus throw of these small lenses is also way too accelerated ( something addressed in the rare Mk3 set) so good luck to the AC asked to do any intricate work at F1.2!

These issues aside they are still an interesting set of lenses and the list of films shot on them is legendary. When conditions are right they yield memorable images... what some refer to as the 'magic' that happens between wide-open and T2.

                          





Also got to try out the Dana Dolly in Seattle. An interesting proposition for tracking over obstacles and rough terrain... two scaffold tubes supported on stands. Works great till you get it at height...where its lampstand/central support begins to struggle a little with stability.

Morpheus 80-200 T2.8



Developed initially for the Bourne and Bond films, this TLS (True Lens Services) rehousing of a stand-out Nikon zoom is mechanically superb.
The focus throw is smooth and steady and the build quality feels like something Cooke might have offered.


I was testing it alongside an Angenieux 45-120 T2.8 and the results surprised me. I expected the Angenieux, at many times the price, to dominate...and it did. But the Morpheus performed better than I had imagined.  

Brendan McGinty

I have always liked Nikon glass, and for the most part preferred it to the Canon offerings in the same class. The 80-200 was considered an exceptional zoom in the stills world. But then the stills world does not have the same demands as the motion world, and it's full frame glass was never designed to hit a S35 target.

A surprising side effect of this optical crop is the geometry of the Morpheus. It yields very flat reproduction with no signs of either barrelling or pin-cushioning. The colour rendition was also good, similar to my Nikkor primes...falling somewhere comfortable between the warmth of the Angenieux and the coolness of an Ultraprime.

Shooting wide open made the price tag difference immediately apparent and, as you might expect, the Angenieux was sharper at T2.8. These differences had disappeared by T5.6 where the Morpheus looks rock solid once again.


Its 5' close focus feels a bit shy at the 80mm end, but it makes up for this by maintaining it at the 200mm end, where it feels pretty close. The 80mm CF was optically good but the 200mm end starts to look a bit 'smokey' by comparison. I had expected the lens to be weakest here, as its where you are asking the most of the zoom optics. 

The flares were of the pointed star variety rather than the orbital blooms of the Angenieux. These stars extend out into warmer orbs.

Brendan McGinty

Overall it's a great piece of glass offering a very useful focal length. The 80-200mm range so common in stills is relatively uncommon in motion. At 2.3 kg it's reasuringly heavy for a lens that was developed for handheld shooting. 
Designed for a full frame sensor the glass comfortably covers the Dragons large 6K sensor.

For its price tag its exceptional.

DJI Ronin

My first test of the Ronin and I am impressed!

With the addition of an Easyrig I was up and running in SmoothTrack mode in minutes, delivering a fairly intricate unrehearsed follow shot on a 16mm lens (this at 6KHD, so fairly wide).





I found it very intuitive to use... still need to get used to its visual signature and 'quirks.'
Always exciting to expand the vocabulary of camera movement tools out there. The 'handover' potential of this system is particularly exciting.

Next challenge will be the addition of a trimmed down mattebox and remote focus unit... whilst not maxing-out the gimbal's motors!

Update:

Here pictured with Arri LCS remote focus, wireless video, full HD monitoring, Duclos 11-16mm and an LMB15 mattebox.
The 'quirks' are ironed out and now, together with the addition of Flowcine's 'Serene-Arm', I am getting motion stability on a 32mm lens! (this with a set of UltraPrimes which work equally well for weight/balance)

Phantom 4K

Shooting with a Phantom 4K camera at Sunbeam studios. 
925 fps at 4096 x 2304.
The resolution aside, its the 'look' and latitude of the new sensor thats so striking. We were shooting at 800 ISO and the picture looked very clean, with a shadow detail and a highlight roll-off unlike earlier Phantom incarnations.








The piece required two distinct visual approaches. 
For the second of these we used a Red Epic Dragon shooting at 6K.
The glass for both cameras was UltraPrimes but the filtration differed, diffusion filtering for the Phantom and Streak filters for the Epic.
I found all but the lightest grade of the Streaks too heavy- handed... but a touch of this gave us the aggressive horizontal flares we were after.




The lighting required the usual high speed volume, provided by large flicker free daylight sources.
This was augmented with hard in-shot flares and DMX controlled shutter dimmers.






Great team work from the 16oz crew, gaffer Martin Smith, Jason at LoveHighSpeed and the assured creative hand of director Michael Lindsay.

Flare Test

Looking at prime lens flare signatures for an upcoming spherical shoot.

I tested the Zeiss/Arri Ultraprimes, The Luma Tech Illuminas and a set of cinevised Nikkor AIS lenses.
I shot wide open against black to show the flare characteristic at its most extreme. 
All shots are with a Red Epic MX sensor at 4KHD (so S35 sensor scale) 
The camera was set to 6000 kelvin with the Flare provided by a Dedo DLed4 and the Key light a Cineo Maverick (5600K).
There is motion blur on the flare shots as these are screengrabs off 25fps camera moves.
Thanks to AC Dan DiMartino for stand-in duties.

UltraPrimes 32mm and 85mm, both at T1.9





The UltraPrimes held the most contrast whist providing a distinctive 'ordered' series of red and green orbs... predominantly leaning to red.

Illumina S35 mk2, 35mm and 85mm both at T1.3





The Illuminas provided by far the heaviest flare with more smoking and streaking than the other sets. Multiple large signature orbs leaning more towards green.

Cinevised Nikkor AIS 35mm and 85mm both at F1.4





The Nikkors sat somewhere between the other two sets. Less contrast than the UPs, less streak than the Illuminas. Large orbs mixing red and green.

Will probably go with the Illuminas on this job.

Zambian Heat

Punishing heat in North Luangwa. 
We measured 58 degrees C in the sun, but as this would be a world record I suspect we were wrong. 
Very, very hot.
The landscape was scorched, the Mwaleshi river evaporating more each day and all electronic gear was left struggling at these temperatures. 






Whist the Red Epic soldiered on, the fans would run noticeably higher. DSLR's shut down, monitor fans were screaming, a hard disk recorder and a laptop shut down. The best approach in these conditions is shooting dawn and dusk in the low flaring warm light. And then hiding from the harsh relentless overhead heat of the day. Sun umbrellas are your only defence at midday.

A distinctive hard light burnt throughout the shoot, as the water sources became dramatic battle grounds for survival.












The performance of the Selex Merlin TI thermal camera at night was impressive, this utilised by our two Natural History teams. The only one of its type in the world, it looks like a prototype, but delivers breathtaking monochromatic night scenes. Heat patterns and fine textures were made apparent in trees, grass, water and sky. The detail and subtlety of its thermal image are unlike any I have seen. Its not destined for any sync-shooting though as the fans raged audibly in order to cool its sensor to sub zero operating temperatures.
