Welcome to Shift 4 and our video comparing the new Panchro/i Classics lenses with a rehoused
set of Speed Panchro's.
Cooke Speed Panchros are one of the most popular kind of vintage lenses in use, they have a
distinctive look and flare easily.
Because of this Cooke decided to go back to the original designs for the glass and build
them in S4/i style housing.
Cooke Speed Panchros have always had a distinctive bokeh, which both these and new classics
seem to share.
The iris makes a circle shape which is maintained throughout the T stops.
When wide open defocused highlights have a more defined edge adding to the distinctive
look.
On top of this both lenses warp defocused backgrounds at the edges of frame, again adding
to an imperfect, vintage look.
The Panchro Classics have an overall warm look similar to the Speed Panchros, which
help produce pleasing skin tones.
An advantage to the Classics is consistent colours and white balance throughout the set.
Most old Speed Panchros, due to the ageing coatings, can have wildly different white
balance from lens to lens.
A part of the original Speed Panchro's look is it's early "fall off" of the focus
from the centre of the lens to the edge of frame.
The Panchro/i Classics have kept these characteristics.
Sharpness in the centre of the Classics is not overly sharp giving pleasant detail rendition
and is consistent across the whole set.
Looking at this particular set of Speed Panchros, the sharpness at the centre of frame varies
from lens to lens, some similar to the classics, others softer.
Both the Classics and the Speed Panchros flare easily.
Flaring in the old Speed Panchros set is varied and unpredictable from lens to lens.
Some with lots of interesting shapes, others with vail flares filling the frame.
The Classics seem to flare more consistently across focal length and are more controlled
compared to the most extreme example in this particular set of Speed Panchros.
The new Panchro/i Classics have a lot of the characteristics of the original Speed Panchros.
Pleasant sharpness in the centre with focus falling off quickly at the edges, as well
as distorted, dreamy defocused backgrounds.
Modern adjustments in the Panchros Classics are consistent colour and white balance as
well as consistent flares.
Also, with some Speed Panchros sets, the soft focus and inconsistent white balance can make
them only viable for fast cut promos or commercials.
The modern touches and consistencies of the Classics, along with S4 style housing and
i technology built in, make these lenses more usable for projects like long form drama and
features.
