  • 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 :)

Sigma Cinema Lenses

"The Sigma Cine 14mm T2 is a lens to behold. Probably one of the largest aspherical elements around and it's right up front at the business end. Took a look at RED Dragon 8K VV coverage today at Duclos and it covers really, really well with only close focus causing heavy vignetting in the corners at 8K FF, 8K HD and WS are clear and it looks pretty nice. The Zeiss 15mm (one of my favorites) and Laowa 12mm are the other great choices for 8K Dragon if you need ultra-wide rectilinear optics around T2.9. Next up from there is the Canon zoom at f/4 for 11mm."

From what I'm reading the prime lenses are only 180 degrees focus rotation? that's feels too low to me, would like something in between the 250-300 degrees of focus rotation. Also, seems like the mounts are non interchangeable by the user and almost all the lenses are different sizes (length wise). those are drawbacks that makes those lenses almost non acceptable for my needs, but I will give them a test drive anyway if I could rent them for a day, maybe I'm wrong...

On the good side, the rehousing looks top notch and the glass optically better then the CP.3.

Yeah, it's the only thing (spec-wise) that's not very good. The rotation for my CN-Es are 360 and even that gets a bit narrow when focusing far away subjects. Just having 180 degrees is quite the difference.

Hey Oron,

Optically are somewhat better wide open, yes.

CP2/CP3s have better coatings, tonal response and bokeh tho.

Also CP2/CP3s mechanics are HUGELY BETTER, much more solidly built and a better investment for sure...imho
 
Tommaso I have a quick question for you. I have 2 CP.2 lenses, one which is relatively new and extremely "tight", somewhat hard to turn, and one which is used and extremely loose, very easy to turn, but the focus ring seems to rock forward and back a tiny bit (seems like it's too loose). Which is the correct state for the CP.2 line (and should I take one of these in for service)?
 
Jim,

you should use more the newer one (it will loosen with time unless you live in Finland ha!) and absolutely you have to service the older one!

I honestly never found a "loose" CP2...but I used a couple of sets which surely passed through the right hands and they were incredibly smooth, almost like Cookes!

CP2s in good shape are a pleasure to work with mechanically.

Of course you have to work around their limitations (optically) but for the price they're quite good lenses in the end.

Look at the relative rotation needed to focus between infinity and 6 feet
The Sigma's use cam's to focus, the Canons use a helicoid - with cam's you get more rotation where you need it - on the long end and less where you don't want it - towards close focus

Don't get caught up in the overall degrees or rotation, in this case it's the much less important part of the story.

But, but....it's a Zeiss- it MUST be better-somehow.....;-) (Canon actually but you get the picture)
Producers don't care about details like ergonomics-they want ***:party:ZEISS:party:****
 
Hi Matt

Great news about the cam system..

Those pic look like mockups and the lenses I saw at IBC where not, if I remmber correctly, quite like that... Anyone got pics from NAB form functioning 35mm?

If the pics are accurate the helpful acceleration/deceleration of the sigma primes foucs is exceptional!

thanks

M

FWIW, Sigma consciously decided to keep the total rotation at 180° to facilitate manual focusing by solo operators when needed. Thanks to the cam system, as Matt notes, the scale is well distributed so that a bigger turn is not necessary.

For many years the CINE lens market was pretty airtight, now we have a rush of new players. If owning your own set of affordable (relatively speaking) CINE primes is on your agenda - try before you buy. I was impressed with the Sigmas at NAB and look forward to shooting with a set this summer. Full disclosure I have worked with Sigma on occasion. That said, I still wouldn't buy them - or CP3s, or Tokina Vistas or LeicaMs - without a proper, real world tryout.

Hi Tommaso,

Interesting what you say about the coating. I also think that in the end of the day, it's not all about sharpness, every lens has a "feel", I prefer the Zeiss for most things. I also prefer the Zeiss focus rotation, and if the mechanics are better from CP.2 that's great, CP.2 will probably be a much more solid investment for rental and easier to charge an extra for in my opinion.
 
When are these things shipping? BH still says Pre Order. Things were so loud about these and then they just went silent.
 
Any Sigma 18-35 T2 owner here please ? I'd like to know if the Canon mount is strong enough to support the lens without rods. It seems quite heavy.

Thanks,

Kristin
