Guest Kal Karman Posted March 23, 2009 Posted March 23, 2009 (edited) Hi there, Anyone have an idea how to shoot Anamorphic with a Canon 5D Mark II? What adapters, lenses etc.. Thanks, Kal Edited March 23, 2009 by Kal Karman
Premium Member Oliver Christoph Kochs Posted March 23, 2009 Premium Member Posted March 23, 2009 There were some 1.5x lenses made by ISCO (schneider kreuznach) that had Contax and Nikon mounts. With the adaptor they'll be usable on the 5d2. I have tried mine but it seems like it needs adjustment.
Premium Member Oliver Christoph Kochs Posted March 23, 2009 Premium Member Posted March 23, 2009 http://kevincameras.com/gallery/album5904 They're called Iscorama lenses.
Nico Hardy Posted April 15, 2009 Posted April 15, 2009 I have the iscorama lens and have used it on the 5d mkII. It's a bit complicated to use as a general purpose lens, specially to focus it. the cle focusing range is very spaced out, but the midrange goes very quick (almost like a still macro lens). it only goes down to something like 6ft, so any kind of CU needs a diopter. also (at least mine) is VERY low contrast. I love it, but it's not a great lens if you're crazy about sharpness and "quality", but it definitively has a personality. the lens is not part of a set. This one is it This is a still shoot with the iscorama on a set, but it will give you a good idea what it can do. -yes, it has a +1 diopter in it and the contrast is crancked way up- Nico
jeremy toth Posted June 3, 2009 Posted June 3, 2009 Hi Nico, Does it also have the flare characteristics of a anamorphic lens? Do you have any examples? Jeremy
Nico Hardy Posted June 4, 2009 Posted June 4, 2009 My personal experience with anamorphics is a bit limited, but my guess is that it looks more like a cooke converted anamorphic or older lomos that a panavision C or E. the flares are warm / yellowish, not cold. They flare more as an elegant straight horizontal line that fades to the sides rather than solid. If you're trying to redo the flares in the new Star Trek, this is NOT the lens to do it. This a low contrast lens. The lens doesn't have a FL inscription, but on the canon 5D the height has the FOV of a 50mm. this lens is a 1.5x compression, not a 2x. don't have files at hand, when I do, I'll post some flare examples. hope it helps.
Leo Anthony Vale Posted June 4, 2009 Posted June 4, 2009 What's the focal length? The Iscorama like other anamorhic attachments is afocal. It screws into the prime lenses. the widest 24x36mm format lens it can be used with is 45mm or 50mm.
jeremy toth Posted June 4, 2009 Posted June 4, 2009 Thanks Nico. I found an example here http://www.flickr.com/photos/graciform/3448194527/
Nico Hardy Posted June 5, 2009 Posted June 5, 2009 No problem. yeah, that pic in flick does just about the same look I was trying to describe. BTW, I know isco also made anamorphic attachment in different screw sizes, but this particular lens was designed as a unit. An interesting side effect is that it has to levers that allow you to control the direction of the anamorphic element. I read that originally it was designed to take apart the front element and use it in the enlarger to de-squeeze the image. I've talked a director into using it on a TV commercial in 2 weeks. I'll post it when finished.
Jean Leclerc Posted June 6, 2009 Posted June 6, 2009 http://kevincameras.com/gallery/album5904They're called Iscorama lenses. Is this the same lens? http://cgi.ebay.com/Lens-Isco-Iscorama-MC-...%3A2%7C294%3A50
Premium Member Oliver Christoph Kochs Posted June 6, 2009 Premium Member Posted June 6, 2009 Looks like a later version. Mine is not multicoated and it is very soft. I have the same softness problem with my older moeller anamorphic lenses. It seems they're too old to meet todays demands...
Chris Gloag Posted June 6, 2009 Posted June 6, 2009 The Iscorama like other anamorhic attachments is afocal. It screws into the prime lenses. the widest 24x36mm format lens it can be used with is 45mm or 50mm. How? More questions... Is it possible to attach any prime lens above a 45mm or 50mm? Once the 5D MII records a squeezed 1920x1080 1.5x image, when you de-squeeze in post, what's exactly the resolution you will (better) get? Upsampling horizontally above 1920?
Chris Gloag Posted June 7, 2009 Posted June 7, 2009 These offers on ebay are really pricey! Take a look: http://forum.mflenses.com/isco-goettingen-...-m42-t4951.html 160€ + shipping... Nico, How much did you pay for your Iscorama lens?
Leo Anthony Vale Posted June 10, 2009 Posted June 10, 2009 How? More questions... Is it possible to attach any prime lens above a 45mm or 50mm? They simply screw into the filter threads of the camera lens. Thread adapter rings may be needed to fit one on to your lenses. The camera lens' focus is set at infinity and all the focusing is done on the Iscorama. Here are specs on some of the Iscorama lenses: ISCORAMA-54 Magnification (horizontal).......1.5x Distance Scale..........2m to infinity Rear Barrel Diameter...........78mm Rear Lens Element Diameter...54mm Length..............................102.5mm (maximum) Net Weight........................1000 grams Filter Thread......................95mm Rear Barrel Threading.........77mm Light-loss Absorbtion...........1/3 Stop or less ISCORAMA-42 Magnification (horizontal).......1.5x Distance Scale...............2m to infinity Front outside diameter..........87mm Rear Barrel Diameter.............43mm(?) Rear Lens Element Diameter...42mm Length..............................83mm (maximum) Net Weight........................750 grams Filter Thread......................82mm Rear Barrel Threading.........62mm Light-loss Absorbtion...........1/3 Stop or less ISCORAMA-36 Magnification (horizontal).......1.5x Distance Scale...............2m to infinity Front outside diameter..........76.2mm Rear Barrel Diameter.............52mm(?) Rear Lens Element Diameter...36mm Length..............................73.9mm (maximum) Net Weight........................400 grams Filter Thread......................72mm Rear Barrel Threading.........49mm Light-loss Absorbtion...........1/3 Stop or less ISCORAMA WIDESCREEN 2000 Magnification (horizontal).......1.5x Distance Scale...............none (fixed focus range 6m-inf) Front outside diameter..........59mm Rear Barrel Diameter.............49mm Rear Lens Element Diameter...36mm Length..............................50mm (maximum) Net Weight........................225 grams Filter Thread......................none Rear Barrel Threading.........49mm(?) Light-loss Absorbtion...........1/3 Stop or less http://lavender.fortunecity.com/lavender/569/anamorphic.html Nico's lens is apparently the Iscorama 2001, which is a single unit. The earliest Iscoramas which came with a Nikon, M42 or Exacta mount were detachable in order to use the anamorphic on a slide projector. One of the most unusual (and rare) lenses ever produced for the Exakta was the Isco Göttingen 50mm f2.8 Iscorama. During photo taking, the lens permits vertical or horizontal picture shrinkage. It's a two part lens, a modified automatic 50mm f2.8 and a special anamorphoser. This is a very interesting lens and fun to play with. You can make short objects tall, fat objects thin, etc., just by depressing the two buttons and rotating the front elements. ---Capt.Jack's Exacta Page http://captjack.exaktaphile.com/Isco%20page.htm Yes they can be used on longer lenses. The front diameter of the camera lens shouldn't be larger than the back element diameter of the iscorama lens.
Nico Hardy Posted June 16, 2009 Posted June 16, 2009 I'm no expert on the matter, but I can assure you there's a difference between the iscorama adaptors and the iscorama lens made for nikon mount. the adaptors are meant to be used with regular lenses as long as the filter's diameter and coverage allow it. The iscorama pret-a-porter is a unit consisting of 2 parts. the mount side has a few elements and f-stop ring only (no focusing ring), while the anamorphic (front) part has an element that protrudes so far back as to be impossible to use on any other regular lens. When I researched purchasing the lens, The same single unit out of polish EBay came up as the only alternative, but 3 years later it's still there. I smell a scam or something of the sort. Does anybody ever seen something similar to it? Hope the crappy snap I did of the 2 sections of the lens will explain what I'm saying. BTW, I just shoot a TV commercial with it, it looks fantastic. So much for expensive gear....It feels a bit subversive to use equipment clients would consider unfit to use compared to the usual fare. A childish pleasure, but a pleasure none the less.

So, are you implying that the model you have simply doesn't screw into the filter threads of the camera lens?

Phil Holland Posted June 22, 2009 Posted June 22, 2009 (edited) I actually have the Isco Gottingen 50mm f/2.8 Anamorphic lens and have been using it for about 3 years now. Here it is on a 1Ds Mark III Originally I was interested in shooting stills in a new format, more of a one shot panorama format. Here are a few from the Isco. Isco f/8 Isco f/2.8 - bigger Isco f/2.8 (note alignment of the anamorphic element is slightly off, you can indeed rotate it) - bigger Isco f/11 As my fascination with using anamorphic glass got the best of me I ended up spending some cash on getting more and more anamorphic elements. Which led me to having Panavision machining together a 100mm 2x anamorphic lens based on a Canon 100mm f/2. I also recently fitted an old Kowa 1.75x on the front side of a Canon 100mm f/2 as well. Hope that helps. Edited June 22, 2009 by Phil Holland
Jean Leclerc Posted June 23, 2009 Posted June 23, 2009 (edited) So Phil, can't you help here? http://www.cinematography.com/index.php?s=...st&p=290628 Is it yours the same model mentioned above? Does your model screw into the filter thread of the lens? Can we use different focal lengths? Or are we just confined to the 50mm focal length? Edited June 23, 2009 by Jean Leclerc
Phil Holland Posted June 23, 2009 Posted June 23, 2009 Sure I can help with that. So the Isco lens that I pictured does in fact screw onto the 50mm underlaying lens, but it's not as you imagine. The anamorphic elements protrudes past the threads and goes deep within the accompanying 50mm lens. You would need to use some sort of threaded spacer and likely a step up ring to use the anamorphic element with anything other than the 50mm prime under it. I would say that you won't be shooting with anything wider than that particular 50mm on it. I get heavy vignetting even with a 100mm lens wedged behind it. The Isco anamorphic seems to be most suited to just be used with it's 50mm base lens. They were designed for each other. This was a point of frustration for me as well, but I eventually went crazy and bought a ton of anamorphic glass to experiment with and rip apart. Here's an example off a custom machined 100mm 2x anamorphic. - bigger I've also recently been messing around with some Kowa glass with is a 1.75x. That above image was shot at f/2.8. Here's what it looks like in camera.
Chris Gloag Posted June 24, 2009 Posted June 24, 2009 I would say that you won't be shooting with anything wider than that particular 50mm on it. I get heavy vignetting even with a 100mm lens wedged behind it. 100mm? I thought it would be wider than 50mm?? How can you have heavy vignetting with a 100mm lens? Did you try other focal lengths between 50mm and 100mm? Or longer than 100mm?
Tom Lowe Posted June 25, 2009 Posted June 25, 2009 I assume we are talking about using anamorphics for 1080p HD video mode shooting here? Phil, what type of anamorphic lens could be used to cover the entire FF35mm 16x9 sensor area of the 5D2 in video mode, and then result in a 2.40 scope aspect ratio when unsqueezed? I suppose there would be a slight resolution gain on that. I wonder if shooting anamorphic might also help to eliminate some of the moire pattern bullsh#t the 5D2 produces in video mode?
Nico Hardy Posted June 25, 2009 Posted June 25, 2009 Maybe i wasn't clear enough on the earlier post. the reason I showed the Iscorama in 2 pieces is to show the protrusion that is behind the anamorphic element. Mr. holland explained in a very didactical way the using of the lens. I second his experience completely. Unless one is ready to do some heavy work with adaptors, thread reducers, spacers and the like, the best way to enjoy the iscorama LENS (not the iscorama anamorphic ADAPTORS) is to just use the whole units altogether. The back element in the anamorphic front is too small and too far apart from the filter thead. If you want to use different lenses, I suggest you look for the iscorama ADAPTOR (or other brands that you may fancy) as the ones explained in detail on an earlier post. The lens can be used as a stills or for HD in the 5D2. pulling focus is a bit tricky, if you're experienced it can be done, but an AC is nice for mode demanding situations. Also the minimum focus is something like 6 feet, so diopters are in order for CU work. When it gets clearance from the client, I'll post a commercial I just did with it.
