  • 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 :)

Lens shopping...

It seems like with the wide Compact Zeiss you are trading speed for full frame coverage. Am I right in thinking that most full frame PL glass has that issue on the extremes? Is it in part a limitation of the PL mount? (Mitch? Matthew?)... leading to the planned "Red mount" being specific for full frame or 645?

The new Compact Primes cover 24mm x 36mm full frame.

From an earlier question (can't recall if it was this thread) the weight on each lens is about 1 kino / 2.2 pounds, which is very, very lightweight.
 
I had the chance to check these lenses out this morning at Band Pro. I'll post a preview in the lens section in a little while but I have to say the barrels are very impressive. There are some other improvements but the optical formula and glass element are taken right out of the ZF line. Remember on full frame a 28mm is the equivalent of an 18mm, so for FF this set really has a T2.1 wide.

At the risk of sounding like an annoying broken record, if that is the case then the lenses would breathe? Right???:) (perhaps some one could ask them directly? (If it does have an effective constant focal length then that would be just too cool :)))
 
Evin,

Thanks for the info, and the preview, very informative; the new primes look very sweet indeed, nice close up.

My question was does the combination of working with a PL mount and being full frame make the lense slower for example on the Compact 18mm is T3.8. Is there an inherent trade off or is it the design of that particular lense.

What I really don't understand is why Zeiss doesn't start building Superspeeds again. Was lead that important to the process??

Some other questions I have, maybe this was posted elsewhere? What is the frame coverage for:
Cooke S4s
Ultra Primes
Zeiss Superspeeds
Zeiss Standardspeeds
Which are the lenses I generally use.

Also regardless of the coverage the rear elements on the Compact primes look pretty far back. I wonder how much they vignette on Red do to the angle that the light is hitting the sensor? Evin?

I can answer two of the questions. An 18mm FF35 lens that is faster would be exponentially more difficult, expensive and much larger. Physics Optics you know stuff like that :-)

No Superspeeds because no lead glass, redesign for the new glasses much dinero.

We saw no vignetting on a RED or F35 or D21 or...

Remember the image circle is 43.3mm diagonal.

Guess that was 3 answers hope that helps
 
Law of Physics Optics...

Wide angle of 19mm f/2.8 is still available from another brand (Leica) and it could be converted/rehoused to PL "easy".

I feel like I've encountered other wide lense full frame glass that is not that slow and not super expensive. I think most people are reacting to the T3.8 18mm Compact Prime and thinking, why? Or, once you've paid 40K for a set, why not pay 45K and not have that problem.

What is the verdict of the investigation into the image circle size of the RED 18-85mm zoom lens? If it was stated somewhere else, please pardon me and steer me to the right place, please.

I have been notified to take delivery of the zoom lens, this information is crucial to my final purchase decision.

Thanks,

We are still collecting the data and verifying the image circle across the zoom range (which changes). I can say that 5K 2.40:1 should not be a problem with EPIC-X. More details as soon as we finalize the work.

Ian: I think the answer to this is that these lenses are mostly based on the excellent but older Contax/Yashica lenses. Several of the lenses - the 50, 85 F1.4, etc. were very fast and were so good they really didn't need updating in any way, but the 18 I suspect is this:

C/Y Distagon T* f/4 - 18 mm

http://www.zeiss.de/C12567A8003B8B6F/EmbedTitelIntern/Distagon4_18mm_e/$File/Distagon4_18mm_e.pdf

Excellent, but fairly slow for a cine lens or even a modern SLR lens. It was apparently designed more with aberration correction and compact size (the front is only 70mm) than speed.

"Its special features are excellent image quality, a good distortion correction unexpected in this type of lens and an exceptionally compact design. The new version of this lens provides the same image quality as the well-known and time-tried design when photographing subjects at a long-distance. New, however, is the design of the focusing system. When the lens is focused to short distances, the positions of the lens groups change in relation to each other. This counteracts the loss in image quality in the outer zones of the image and extends the useful range of the lens to 0.3 m."

It would seem that Zeiss decided to go with existing designs in order to get them produced quickly enough to be relevant in the market.
 
Hey, now what will you do with that pink plastic toy?
plastic is absolute shit, now look: it's in the plankton. Animals are eating plastic, and you'll end up with a piece of plastic in you plate when you order fish at a restaurant.

Why you also painted it?? I don't get it.

Holga: why using 6 cm tall film if the lens is the cheapest on earth and made of plastic. You will go on spending more on film than the price of the camera. wasn't freedom from film one of the main reason for digital camera success?
And Lomo: from fantastic cine glass to the worse still cameras ever.
Isn't any pre-digital olympus, pentax, nikon, anything... immensely better and more reliable than a children camera?
Their slogan, "don't think: shoot" tells a lot.
Don't think: buy it.
Buy it and throw it.
A blasphemy in photography and commerce.

I don't know. Can we deeply comprehend the abyss?
I can't. I may only understand that we "can" go there. Whatever it is, and once there... sono cazzi amari! (and rightfully so)
Sorry, I can't translate it.
