  1. Trying to understand / fix the LA7200 to make it clearer, less CA, sharper and more usable. Building a lens from other lenses to attempt to do this. In any case, im trying to understand what is causing the issues in general using the LA7200 on DSLR or Blackmagic cinema camera. Is it because of the sensor cropping then? The LA7200 was designed for a 4:3 sensor crop therefore it will not work correctly on the BMCC, or larger sensors? Or is it simply a design flaw overall of the LA7200 , poor lens design / poor coating If it is a crop sensor issue, what is happening on the LA7200 to cause issues because the sensors are larger crop. Is the back lens element simply too small, where the image is being projected against the taking lens too small therefore when desqueezed you see parts of the image you really should not? i.e. the taking lens and the sensor is capturing too much of the la7200? By adding a diopter behind it does that then, make it larger i.e. projects less of what is seen from the front of the la7200 to the sensor? Or is it more complex than this. I have tried using a diopter behind the LA7200 i think its a Tokina 0.5 Not sure. I mean it says No 0.05 so I dont know at this point. In any case it does not seem to help. Just trying to understand, thanks anyone that can help.
  2. Hi, I would be hugely greatful if someone can offer me some advice on this lens and the problem i have with it. I have just recieved a Isco - Gottingen lens and the focus ring seems to be locked at 16m. I'm unable to focus and was hoping someone was able to inform me the correct way to be able to fix this, or inform me as to which sew to undo. Many thanks for you time :)
  3. Hi, I'm starting doing anamorphic photography and EOSHD has been great helping me understanding this technic. I'm shooting with a Nikon Df that have a 3:2 ratio. My anamorphic adapter is a Kowa Prominar 16-H 2x. To find the aspect ratio, I took a photo at home to a circular box and squeezed the image until it turned circular. It gave me a ratio of 2,82:1, as you can see in this image https://www.dropbox.com/s/bmq13xv97syuzx5/DSC_7602_2%2C82.jpg?dl=0 I read an article somewhere that talked about a value of 2,66:1. I tried that but the box resulted a little ovalized https://www.dropbox.com/s/qxmxy9qtn9iokgi/DSC_7602_2%2C66.jpg?dl=0 Is my aspect ratio correct? I have this doubt because I can't find anywhere what's the best ratio when we are shooting in 3:2. My first anamorphic images with a 2,82:1 ratio https://www.flickr.com/photos/[email protected]/sets/72157649089398262/ Thank you, Nuno Boavida
  4. I've been looking everywhere, but I can seem to find anything solid on squeezing anamorphic footage on Premiere Pro, only found methods for FCP. If anyone knows the best method of squeezing 1.5x and 2x anamorphic footage on Premiere Pro, that would be greatly appreciated.
  5. I've just received my second Iscorama Cinegon. The first Cinegon I have I noticed when I rotate the focus ring below 2m it will just fall apart. This doesn't happen to the original Iscorama I have. I thought it was the fault of my Cinegon at the time since its condition was so bad. When I got another Cinegon it's just exactly the same as the first one. It's like you're screwing the front glass out. So, is it normal for the Cinegon version?
  6. Hello, I've been experimenting with shooting anamorphic video on my GH4 in 4K photo mode, using a Rectimascop 48/2x adaptor. The more I shoot, the more I see the need to monitor the unsqueezed video in real time, for better control of composition and focus. Can anyone recommend an HDMI field monitor, 5" to 7", with the ability to stretch the video width x2? Many thanks, Izhar
  7. I'm read threads at RU, DVXuser and here. Looking to get a relatively cheap anamorphic adapter for around $500. It seems that the Kowa 8Z and its alternatives is a good bet. I've seen others that are projection style but the EOSHD book states that they should be avoided. Is that still true? Essentially avoid this http://www.ebay.com/itm/321535626176?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
  8. Hello everybody! I listed a 2000 MC Isco anamorphic lens on eBay. If someone wants can ask questions. I bought this lens is 2 years and never used it, she is very well cleaned glass has no scratches or fungi, only a detached rear element. I did tests with a zeiss 35mm f2.8, Canon FD D1.4, Elgeet 12mm F1.2 (ETC), V6x17 (ETC), Angenieux 17-68 (ETC) all with a GH2 camera, and the images do not appear nothing detachment. I did a little test video, 2 days ago with a Canon 50mm f1.4 and can be seen here: Ebay link: http://www.ebay.com/itm/111494558009?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 You can also ask and accept offers. Thanks
  9. I have a question regarding the LA7200, basically in order to focus you would to move the back lens element or front. Would that be correct? Would it be possible to allow focus by adding another lens element behind the flat back lens element. Not sure how the image is presented by the square back of the LA7200. Im currently in the process of modifying it and frankensteining the lens with old junked vintage lenses to make it one whole lens that does not need a taking lens. Just want to make sure I have the physics right. Thanks in advance.
  10. Testing my Sony a7s with kowa prominar 16 H, Taking lens is a Russian Jupiter-11A
  11. I want to get everyone's opinion on this. Should I buy anamorphic lens or a dog schidt lens w/ the oval aperture? I'm wondering why people still go crazy on ebay for anamorphic lens when you can get the dog schidt lens with the option of a 1.5x or 2x oval apeture and is single focus. Essentially, both the anamorphic and DSO lens produce the same results as far as oval bokeh and flares, I would think. Is there something I'm missing? You would think that people would go with the DSO lens option as opposed to anamorphic lens seeing as how anamorphic lens require more such as double focus, clamps and other addition things to make them work properly. So, do anamorphic lens have more desirable characteristics (other then the whole crop/squeeze factor) then the DSO lens that I don't know about?
  12. Some moods testing the new photo mode in the 4:3 ratio with my 2X kowa anamorphic adapter. More in the description. Very nice feature to have now.
  13. Hey there, I wanted to share my first test with my SLR Magic Anamorphot adapter and see if anyone else is using this adapter and what lenses they've found work well. Specifically for EF mount. I shot this with a Canon C100 using the Sigma 35mm f1.4 Art lens, which worked beautifully. I'm looking to find other lenses that will work well which I've had little luck. I think it works best with lenses that have a narrow front lens element. Any info would be greatly appreciated! Here is the video:
  14. Aspect ratios including 4:3, 3:2, 16:9, and 1:1. Limited to 29.97P for U.S and 25P for 50Hz shooting. Shooters have the ability to shoot in Cine Picture profiles with full-manual controls. No 23.98 or 24P in PhotoMode. The 1:1 aspect ratio with a 2x anamorphic is a native 16:9. Internal recording at 100 Mb/s. HDMI output is still enabled! Might be a huge advantage to shoot anamorphic with a ShoGun after all! Will the GH4 embed the 1:1, 3:2, and 4:3 in a 3840x2160? I'm noticing a completely different grain structure in PhotoMode... Shot a 16x9 in 3840x2160 in Movie Mode and a 16x9 at 3840x2160 in PhotoMode and the grain texture in PhotoMode shows signs of compression artifacts not found on professional video or film cameras. Sorry. It's almost as if the sensor is acting differently. It's possible to notice the grain-structure change in 10x LiveView. The codec already has issues with recording in low-light, as seen by Dave Dugdale's GH4 vs. A7S demonstration (Dave's video mentions how a white background in low-light causes strange codec issues... I'm in a similar circumstance and it's helping to distinguish the new noise-floor patterns). This new grain texture appears to be present at ISO 320 and above. The white backdrop is close to 35 - 45% luminance values and not 80 - 95%). Needs more testing and proper lighting. Also, I'm under a 5200k CFL and not a professional non-strobing video light. However, this may be distinguishable in future tests with proper lighting and at low ISO values. Keep an eye out for it. Other info about 2.0 firmware... - - No new Gamma Picture profile. - - No 23.98 in 4096x2160.
  15. Testing out the new Metabones Speedbooster Canon EF -> m43. Really loving it, and working with Sigma ART lenses it just sings! I really want that shallow depth of field look, and it works a treat. Of course it's really hard to focus at F1, worse using a vari-ND filter too (vignette and darkening of the corners at the highest setting). Paired with the SLR Magic Anamorphot it has a great look!
  16. Just a quick video testing out a Sigma 35-70mm f2.8-4 canon FD mount I found at a local camera shop for $20. It seems to work better as a taking lens than my canon FD f1.4 for some reason, not sure why. It does have a flat front element. From what I have read online most people weren't very happy with sigma zoom lenses in the FD mount, as far as the overall quality. it was all shot wide open around 39/41mm except for the 3rd shot which was at 70mm. I had heard you could use a 35mm + anamorphic on the gh4 without any vignetting but it is pretty severe when I try.
  17. Please have a look at the music promo I made using a kowa 8-Z anamorphic adaptor, mounted on a voigtlander Nokton 35mm F1.2, using a Lumix GH3. I also had a Tokina .4 achromat and a Cokin Diopter +2 for the Close ups. It was all shot at night which presented problems as the Lumix isn't very good in low light. I was shooting at 50fps which reduced the amount of light I had even further. I also found that if the lens was fully open it was difficult to get a focus. Not because it was too shallow, but because it wouldn't focus on anything! As you can see I over-cranked the ISO on occasion, but I couldn't set lights up on the banks of the Thames at 3am, as we didn't have permission to be there. I wish I'd got someone to stand close by reflecting a bright torch off a white shirt though. I can only hope that I get away with the graininess in the spirit of low/no budget film making, and it looks like 16mm! Staying close to the subject, using the diopters, gave me a picture I liked the most. The bokeh looks lovely and soft and cinematic. Shots where I had to focus to infinity were difficult - the bokeh is ugly in those shots (in my opinion), taking the shape of a kind of horizontal tear. But I couldn't film the whole video in close ups! It was difficult to shot this as a one-man-band. Having to screw two different diopters on or off every time I wanted to change my proximity to the actors made it quite fiddly. I was also moving lights (I had x3 LED panels). I had some other taking lenses, but it wasn't practical to change during the shoot. Lastly, I know its normal to crop the super-wide picture you get from shooting 2x anamorphic on a 16:9 sensor, but I decided to embrace it. It's fun, and a bit silly, but its a music promo, so why not. Hope you enjoy. The track by Durlston George, his debut single, is lovely.

  19. hi guys, i started a vimeo channel dedicated to my anamorphic test with LA7200 and GH2, speedbooster and CANON FD lens. https://vimeo.com/channels/anamorphictest Do feel free to take a look and comment. Thanks, Chin
  20. selling my gold ultra star close focus at 5 feet, comes with a helios 44-2, +1,+2,+4 diopter set, nd filter, step up rings, vid atlantic clamp. going for $350 or best offer. http://www.ebay.com/itm/anamorphic-lens-bundle-/261587403668?
  21. Hello everyone, I'm looking to buy a clamp for my baby iscorama/iscomorphot 8/1.5x. I've read that the clamp that redstan makes for this lens has been discontinued. So if there is anyone who is selling their redstan clamp for baby anamorphics, I'm looking to buy. I've also looked through all the forums related to anamorphics and I know there are several alternatives to mount that lens (f-adapter, step rings, etc.) However, there seems to mixed impressions on all methods. I've tried looking for a step down ring that steps down to a 24mm thread, but can't seem to find one. If anyone knows of the best alternative, that information would be greatly appreciated :)
  22. Hi my dear anamorphic friends ! here is a "Scarface's like" wedding :) and my brother's wedding :) all this was shot in GH4 4K and 1080p 96fps happy end of the summer ! :)
