  1. @Tito You would rethink 4K if you could shoot 4:3 or 3:2 like I'm doing with my GH4.  And you can always downscale 4K to 1080P if you want.  So much less hassle than ML RAW.  File sizes are so much smaller and I can do real time previews too.  If it wasn't for that, I'd agree with you.

  2. I also think the guide should be redone.  Maybe a combination of Andrew's and Tito's guide.  Both are excellent!

    The 2x or 1.8x look will always be the preferred anamorphic format.  I think the new options are very welcome and open a lot of doors for everyone.  Unfortunately at this point you have to buy and experiment yourself to find the right options.

  3. My first test with the FM Module.  This is a few BTS, I'll try and edit the rest of the video later.  One note, a lot of the footage has the adapter misaligned.  I had my friend take the video while I was shooting photos.  He didn't tell me until later that it moved on its mount, so there's vignette and also the top of the frame isn't on the same plane as the rest of the image.  First 4K upload to youtube as well, I hope it works for those people who have large monitors.

     

  4. The taking lens does make a difference.  Even the much touted Helios 44-2 has to be at F5.6 or F8 to be sharp, with or without diopters.  Yes diopters help with sharpness somewhat, but it doesn't really help for shooting wider than F2.8 on some lenses.  You just have to test lenses out to see which works.  If you do a forum search there was a thread when the Anamorphot first came out with compatible lenses listed.

  5. @Andy Lee - I'm looking for another zoom to work with Isco Ultrastars.  The 28-70 is only usable from 50-70mm.  So I'm thinking of a 50-150mm lens, like the Sigma 50-150mm F2.8.  What do you think?  I could use the extra length, but I want the constant aperture.  I know there are Canon FD lenses too, but those are F4.  Any thoughts?  Thanks!

  6. Thanks Rudolf!  You really can't go wrong with the GH4, or A7S too.  They are all good cameras now.

    I used to have Contax Zeiss, sold all of them.  They are very "clinical" in rendering and contrast.  I wanted something warmer so I have moved to Russian lenses and now the Tokina 28-70mm.  The only way you can find out about lenses is to use them unfortunately.

  7. I just got mine.  Man this thing is huge and heavy.  HUGE!  The biggest problem I have is that the anamorphic is a stressed member.  The clamp they include has such a small footprint, and it's the only thing holding up everything.  With the rotating front section, it makes it very difficult to support it all.  And that rotating front section - damn the travel is so long.  Again, hard to put a lens support when it travels that much - maybe an inch and a half travel?  I got an Isco Bluestar so it works well, but I can't imagine putting in a Sankor or Kowa.  Now I understand why Cosimo had to drill the aluminum tube piece - otherwise I can't see how you'd secure the small size of the other anamorphics.  I'll be doing some measurements and seeing if I can get some support for the Kowa, but for now I'll be shooting with the Isco.  I might get a Schneider just to compare which is better.  I really wish they found a way to make the inner section longer so that you can use it as the stressed member, not the anamorphic.  Overall build quality is good, but the front cap doesn't fit well and I have to use gaffer tape to secure it.  For a first run I think this thing has a lot of potential.  Did I say it was HUGE?  LOL

  8. Understand that the SLR Magic isn't sharp with lenses faster than F2.8.  Check out my video below, you'll see that a lot of lenses wide open just aren't sharp.  That's the nature of anamorphics, very few of them are sharp at F1.4 or F2.0.  Usually the projector lenses are OK with wide open apertures, but the SLR Magic isn't.  You usually need to stop down to F4 or F5.6 even F8 to get sharp results.  Make sure you do a lot of tests.  Also - Full Frame (like A7S or Canon 5DmkIII) gets worse results.  Smaller sensors like GH4, BMPCC are better suited for anamorphics.  If you don't like the SLR Magic, then it's time to consider something else.

     

  9.  

    Cosimo has a great idea of wrapping the uncovered section with plastic wrap before taping into the infinity position - this ensures the helicoid grease will remain contaminant free and enable the lens to be re-assembled if needs be without any ill effects from the disassembly and re-mounting process.

    This video is meant as a visual guide only...do not attempt yourself if it looks too risky.

    Edit: As I previously mentioned on the older FM thread, you can make your own version of the FM mounting tube for smaller anamorphics by getting some stock exhaust/ tailpipe tube in the correct diameter (all you need to do is cut it to length). These are made from stainless steel and have a thinner wall thickness than the FM aluminium version - allowing a bit more room inside for an anamorphic to fit: http://www.ebay.co.uk/itm/321033449391?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

    ​Hans thank you for making this video!  OK I'm not so scared now.  I definitely understand how to do this.  Now I can take my Sankor apart hehe.

  10. ​I am not an expert when it comes to taking lenses apart, it was a nightmare for me too, I took the risk.

     It took me 3 and half hours do the job,  with kids going around and my wife complaining:D, I was lucky to have the right pieces, 2 redstan clamps and some ingenuity, I had to drill some holes to the  metal tube that came with the FM, but now I can say it was worth it. I can also say that I thought it was going to be more difficult. I actually had difficulties to understand how to clamp it. I tried severals ways, finally a good idea came into my mind.

    Another problem that I wasn't aware of was to keep the anamorphic to infinity, once I unscrewed the metal focus ring I thought it could stay  at infinity, it didn't, when I placed the sankor into the FM, the whole focus shifted, so, I had to find a way to keep the anamorphic at infinity. I managed to put tape between that space and it didn't shift anymore.

    If you don't like to go through all this, just go the isco/Schneider route, both ways are worth it, believe me.

    Thank you Nahua;)

     

    ​You are one brave man!  I'd be shitting all over myself.  Yeah I'm going the Isco route unless someone can find another way to mount it.  I don't think I would be drilling holes into my new FM adapter.  I just can't be doing these kinds of modifications.  Damn!

  11. I also bought the Tokina 28-70 2.6 as Mr. Lee considered (his suggestions are priceless - thank you very much!).

    I immediately liked the lens very very much. And it is a wonderful match for the Isco 54.

    This combo brought me back from small gauge film to have some (much cheaper) fun with my "old" GH3.

    This brings me to a point: There are so many discussions about 'filmic' look and the lack of it - particular with the GH4.

    I also think the GH2 looked better than the GH3 but maybe I will buy the GH4 as this Tokina makes me trust more

    in the lens for some look instead of the camera.

    So with all my old lenses (Canon FDs, M42's) it could be possible to have a nice and warm look (or whatever filmic is...) with such a

    modern camera like the GH4 or am I totally wrong?

    Again thanks a lot for all the great infos!

     

    PS I thought the Tokina is an old lens - but mine (I bought it from ebay) was sold new in a store last year (according to the bill in the box)?!

     

     

    ​This is my test with the GH4 + Tokina 28-70 + Kowa 2x.  I think the GH4 has the most potential, and it works even better with 4K photo mode recording.  The video was shot 3:2 aspect ratio.  I also had a hacked GH2 then a GH3.  The GH4 by far is the best of all them.

     

  12. I've managed to fit the Sankor 16D inside the FM.

    ​This makes me happy and sad at the same time.  Nice that you made it fit.  But the work that went into it...damn.  I really hate taking apart lenses, and this looks like a nightmare for me.  Please post some tests.  I'd really like to see if it's worth hacking it to fit or just going the Isco/Schneider route.  BTW Cosimo thanks for all your hard work - deals and hacking!

  13. Dismantling the Kowa (or similar) to fit inside is far from ideal - but can be easy to do and straightforward to reassemble without incident. The most important thing is to use correct sized screwdriver - and not to loose the screws!

    I think it may have been optimistic of the FM makers to state compatible lens brands to fit inside - it is far better to follow the maximum 71mm diameter rule.

    Some digital calipers (cheap) to check the widest diameter of the anamorphic beforehand would be a good investment to those who may have a selection of lenses they might want to try inside the FM housing.

    ​I wish they actually tried different lenses to see which really fits.  I saw the demo so I kinda knew I'd have to get an Isco or Schneider.  Still my anamorphic collection is growing.  I'd really like to pare it down and I sure hope the FM works well.

  14. I like having both the Nikon and the Tokina even though they are the same focal lengths they both have very good looks that are uniquely different .

    The Nikon I like to think has a look like an Arri Zeiss Master Prime - a very modern clean strong blacks v sharp wide open modern cinema glass look like Fincher uses

    (they did use this lens on Bourne) 

     

    where as the Tokina has a certain Mojo about it that is probabally more filmic than the Nikon , it just makes everything looks great!! - I always shoot both lenses at f2.8

    inside , outside day or night!!    get the Tiffen NDs on it !!

     

     

    ​I got this Tokina on Andy's suggestions.  Really great lens.  Has a soft focus look until it's sharp, and the F2.8 works really good with speedbooster.  I just wish the focus ring could be locked, kinda wonky push pull for manual/AF "toggle".   I also wish it was single coated, but still flares well.  Very good for people shots with the soft look.
