MELVILLE, N.Y., April 3, 2013 – Canon Inc., the parent company of Canon U.S.A., Inc., a leader in digital imaging solutions, has announced the development of a 35mm cinema prime lens for large-format single-sensor cameras employing Super 35mm, full-frame 35mm, and APS-C size imagers. The 35mm cinema prime lens will look to join Canon’s line of 14mm, 24mm, 50mm, 85mm, and 135mm EF-mount Cinema prime lenses. The 35mm cinema lens in development will look to become the sixth in the line, filling a strategic optical need between Canon’s 24mm and 50mm lens offerings. As with Canon’s precision-matched, competitively priced CN-E prime lenses, the 35mm lens under development will look to deliver 4K optical performance and inherit the professional operability of the existing CN-E prime lens line.

It's not a "line"- its ONE new lens -35mm f1.4

Where does it say F1.4 in the press release?
Nowhere that I can see.
Found that very strange.

The rest of the line is already here or on the way.
24mm 50mm 85mm are out there.
wider and longer lenses coming, though slow on the wide end.
 
New line? More like additional lenses to an existing line. Good though because that lens line was definitely lacking.

EDIT; oops! Just noticed this point was made . :/ sorry
 
All the Canon Cinema lenses have 11 aperture blades. The max the L series lenses have is 8 blades. More number of blades, better is the bokeh. So calling these lenses Cine mod is absolutely not right.

If Canon had to do cine mod, then it can do it much faster. May be Canon should do Cine mod of their L series lenses, to reain their IS. For eg. you will not find a sharp lens like 70-200 f2.8 L IS II USM among other cinema lenses by other manufacturers. Making a cinema mod for it will make sense for people who primarily use their cinema lenses with focus pullers used to traditional cinema lenses.

you are correct - I was typing quick on a phone so 'cine mod' was easier, my bad
 
Still no PL-mount versions though :( Canon's L/CN-E glass has quite a different look to Zeiss's ZF/CP.2 glass though. So it's nice to have additional options for different looks at this price point.
 
The number of blades has only a minor efect on bokeh. It makes OOF speculars rounder when the iris is not full-open, but that's about it. If a lens has nervous bokeh with 8 blades (usually, because the optical formula is tuned for something other than bokeh, like sharpness or manufacturing costs), it will have it with 11 blades. Not that I'm aware of any bokeh issues with the canon 35mm, anyway.


edit: one example

this is my bokeh test with a pentacon 200mm f/4 (15 blades):

and this is the Leitz 35mm f/2.8 (6 blades):

It really depends on the shape of the blades too.

I've seen aperture blades with very different approaches to cutting light. Some are straight, some are curved, some are 'bent' in angle. It's very important, and I don't necessarily fall into the common brochure advertisements that more circular ='s more pleasing. I love the tons of Cooke S4 bokeh from hollywood films from 2000-2008 era. People still do it today, but it seems the octagonal bokeh was in trend during that time period and it looks great during elegant scenes. I think it's classy.

It really depends. As someone pointed out above, it's not just number of blades.

Straight edge, low number of blades.

low number yet rounded to attempt a more circular bokeh.

Low-ish number, blades designed for unique look. I was told by someone (can't remember who) that when the light goes through this aperture, the small 'corners' of the blades influences the light and creates a smoother fall off in focus. I'm not sure if that is true or not. But it is pretty!

High number and rounded for those who can't stand anything but roundy round roundness.




I think preference is important, but I think people have been learning that circular ='s better, when it's not. It's thanks to lens advertising by manufacturers. The ones with very round bokeh say it's more cinematically pleasing... whatever that means! 1,000's of films have been shot with lenses that give beautiful octagonal, hexegonal, or like-wise bokeh. Sometimes obvious sometimes subtle, but none-the-less, blade shape a preference. Perhaps a majority preference in 2013, but none-the-less. I'll be the minority here! Plus octagonal lenses wide open are circular. I always have a choice, whereas circular bokeh folks do not.

Sometimes I prefer the shape of an octal or hex bokeh. Round is nice sometimes. Sometimes I think people et caught up on details that only creators are aware of.
