Ebay here I come!!!!

There's a crop factor in 4K... not good. It seems like Flog does not work internally? Some shots look great though, almost Alexa style.

It took about a year to make. The budget for the shoot was about $25K, includes permits and crew getting paid a bit. A couple regular kinos for this but mostly practical lights.

Sure!

Thanks for the nice comment Sudopera,

So I've had this lens for a few years, and still not sure what is it: So I'm trying to figure out the front lens filter ring size and which lenses was this supposed to work with.

I'm thinking about buying one of those brand new Arri master anamorphics and have it converted to Nikon mount. I have some cash left from the grocery store. Oh no, wait a second...

Seems like it's sold, sorry guys.

Wow, I hadn't heard about that. What could you do in such event?

Updated photos.

All the iscos I've tried were x1.4 even when marked as x1.5. Yeah the edges will get more compression, the compression is not uniform across the frame. But what matters it the middle, the center area.

I haven't actually shot much footage with it. I had it as a stills lens only. Some examples (click on the images for a larger view):

For lack of time to use it I'm considering selling my Iscorama 2004 with nikon mount. This is a very special lens, nothing to do with the more usual, and often referred as, Iscorama 36. This is what wikipedia says about the iscorama 2004: Iscorama 2004 The only sealed anamorphic monobloc manufactured from a premium quality prime, the donor lens being the Leica 50mm f/2 Summicron. The Iscorama 2004s were multicoated lenses, and featured a Leica R Mount camera fixing. So pretty much without any doubts we can say this is among the best if not the best Iscorama anamorphic lens ever produced. And probably the most expensive. This lens comes with Leica R mount and because I wanted more compatibility I decided to send it to Iscorama/Schneider labs for a mount swap, and now it has a Nikon mount. This conversion was pricey (aprox $800-$1000) but worth it because it can now be used on nikon (and canon EOS) DSLRs. And what's more important, the lens mount has been precisely aligned so that vertical lines are... well, vertical. That means no skew on the image like you often see on videos shot with anamorphic lenses/adapters. The iscorama 2004 produces a blue lens flare if a strong light is pointed towards the lens, but it's a multicoated lens, which means it will produce sharper and more contrast images than older iscoramas (which tend to be soft). The condition of this lens is MINT. That means it's in perfect, almost new condition. I'd be happy to return the money to anyone not happy with the condition of the lens. Not much more I can say about this lens. SOLD

If you can't see the difference, then great for you!

    What looks better, 35mm film or a 5Dmk3? Can you make 5D footage look as good as film in post? nop. A good post will get you the best out of the footage but can't do miracles. What's better, a 2009 Ferrari 458italia or a 2013 Subaru BRZ? I'll take the Ferrari thanks. (feel free to replace the 458 with a 911 turbo if you're not a fan of italians). And I love the BRZ, but they play on different leagues.   So the day the 5D can shoot images as filmic as the F35 I'll be sooo happy to leave it at home and just shoot with my 5D.  

  Lol, it's true you can. But in the same way I can plug my old VHS into a HDCAM SR deck and record at 1080p 444, and while the signal will be actually full HD with full chroma resolution...                     well you get the point right?   Chroma sampling and debayering are often mixed and confused. I think it's normal to do so. But it would be great if people get the difference.  For example, since you're mentioning F35 vs 5D. For each pixel in the final 1080 resolution, the F35 had 6 pixels in the sensor and the camera downsampled them to get that one pixel. That means each pixel has full red, green and blue information. No interpolation.  Now, compare that with a bayer pattern sensor like the one the 5D uses, where only 25% of the pixels go to red and blue. From 25% to 100% there's a 75% interpolation gap there. Yep, that's a big gap to fill in compared to a F35 right?

          Probably due to the fact that while Iscoramas are rated as x1.5 anamorphic lenses, they're closer to x1.41 compression ratio if you measure them with a perfect circle. At least that's my experience with the ones I've had.

Hi Andrew, Let me say I enjoy reading your blog everyday. But if you could take an advice, I'd recommend you to double check all the tech info you posted today, because it's full of inaccuracies and technical misleadings. For example, while a RAW to RGB conversion can actually be done with a 444 color sampling, that does not mean that the actual signal carries full color resolution for each of the channels. Such is the case of a CMOS bayer pattern sensor like the one in the 5D. While RAW recording clearly gets rid of ugly both compression artifacts and in camera video processing that throws away information, as long as it is limited to low resolution such as 1920x1080, it will never achieve a great luma and chroma resolutions, just because of the nature of bayer patter sensors. The only way of solving this is adding more resolution and downsampling in post. SO yeah, the raw can be 1920x1080 but the measured resolution will fall far behind that. Anyway I didn't want to make a very long post, this is just one of many issues your article has (like calling 3K a digitally resampled anamorphic image). You could double check your blog entry to avoid having newbies confused. I understand the ML hack is very exciting but facts and numbers still apply. And I say this owning a 5Dmk3, a F35 and some Iscoramas as you do.  :D

  Hey, do you care giving your explanation about that conversion? Sure resizing a 4K image down to 2K will improve chroma sampling, but it won't magically improve bit depth.  :blink:
