Julian Posted May 15, 2013 Share Posted May 15, 2013 I wonder: does it work? Most anamorphic lenses don't let you get very wide. What are the results if you put a wide angle converter in front of the anamorphic? I don't think they change the focus, or do they? Probably not a good idea on big anamorphic lenses, but what about the smaller ones? My Iscomorphot 8/2x is pretty small, would be nice to put a 0.7x wide angle converter on it for example. Or my tiny Petit Cinvesion 1.5x.. It vignettes with taking lenses below 40mm on the GH2. Would like to be able to go a bit wider. Not looking for extreme wide, would be happy with 28mm (0.7x 40mm). I don't have any wide angle converters, otherwise I would give it a try.. Did someone do this before or does someone have the gear to try? Would be appreciated!

Gábor Ember Posted May 15, 2013 Share Posted May 15, 2013 I just did some testing yesterday and a new wide angle adapter is at the post office now, I am taking it home today. The one I have is a Fotga wide angle adapter (0.65x on paper, but it really isn't that wide), it is really good on a Hoya 28mm f2.8 and really bad on everything else. The problem is that on longer lenses (also on my anamorphic setup) it makes the whole image hazy. Highlights have halos. There is a middle ring that is sharp-ish but towards the edges it gets more and more blurry, like if it was shot with a lensbaby. Stopping down improves the image a bit. Now that is only the Fotga. Today I will test the Zomei 58mm slim wide angle adapter. It has a bigger diameter so the edges are farther from the center. I will post some before/after images tonight.

Gábor Ember Posted May 15, 2013 Share Posted May 15, 2013 Well straight away the Zomei is crap. Says 0.45x and I bet it is around 0.9x... and it messes up the focus completely, MINIMUM focus becomes infinity so it needs a diopter behind it to be able to focus closer than infinity :) Quote Link to comment Share on other sites More sharing options...
Julian Posted May 15, 2013 Author Share Posted May 15, 2013 Thanks Gábor. The fact that the Fotga works fine on your 28mm but is crap on your anamorphic/longer lenses is probably bad news. Guess the combination of all those optics just don't work well... Too bad. Quote Link to comment Share on other sites More sharing options...
Gábor Ember Posted May 15, 2013 Share Posted May 15, 2013 It is not specially the anamorphic. If I use the Fotga on the Helios-44M by itself, it produces the same errors. So the problem with the anamorphic setup is that the taking lens is too long (focal length), I guess. Canon 50mm 1.8 and Jupiter-9 are bad too but my friend used the Fotga happily on his Nikon 18-55 kitlens. So it is not about the elements but the focal lengths. Wide angle adapter is for wide but not that wide lenses I think. There are relatively cheap chinese adapters out there. Buy one that you may be able to use on another lens, if the anamorphic gear doesn't like it. I'll recharge my batteries and I'll make some pics.

Tito Ferradans Posted May 15, 2013 Share Posted May 15, 2013 I remember reading in a thread on DVXuser some time back about a guy using a 72mm threaded 0.7x adapter (by Century Optics) in front of his Isco-36 and getting great results. I couldn't find it again, but will keep looking. Julian 1 Quote Link to comment Share on other sites More sharing options...
JohnBarlow Posted May 15, 2013 Share Posted May 15, 2013 The answer to this is a complicated one. In general it is no, but there are exceptions. Look at the discussion to this vid on the tube-> http://www.youtube.com/watch?v=d7mHjrjyOhM What he succeeded in doing was changing the diopter of the Cinelux and placed a reverse matching diopter value lens at the front, which just happened to be the front element of an olympus wcon 8b. Therefore the diopters cancelled giving a zero power 0 diopter composite. Most WA adapters are in the range 7-10 diopters unless you disassemble them for less power (some have 4 elements). He talks about 2 feet which is about -2 diopter on the scope and 2 diopter on the olympus wcon 8b front element. Of course this will make the rig no longer focusable but the wide angle will kind of make it pan focus. Schneider used to make a UWL adapter for super8 cameras, on the variogon lens, but the lens had to be set to macro for it to work. Using it or any WA with a scope may require placing a close up lens between the scope and the WA adapter It is all down to experimentation. I wonder: does it work? Most anamorphic lenses don't let you get very wide. What are the results if you put a wide angle converter in front of the anamorphic? I don't think they change the focus, or do they? Probably not a good idea on big anamorphic lenses, but what about the smaller ones? My Iscomorphot 8/2x is pretty small, would be nice to put a 0.7x wide angle converter on it for example.

andy lee Posted May 16, 2013 Share Posted May 16, 2013 yes it works Ive been doing this for many years with my Anamorphics - I posted about this last year on this forum Century Optics and Olympus x0.7 are the ones I use Quote Link to comment Share on other sites More sharing options...
andy lee Posted May 16, 2013 Share Posted May 16, 2013 Century make quite a few very high quailty x0.8 and x0.7 adapters thay all have great glass as Century are made by Schneider in Germany you need to find one that has a slightly bigger rear end to your anamorphics front end so measure your anamorphic front diameter Also Olympus x0.8 is very very sharp and cheaper I use the olympus alot too both have a plus effect in that they SHARPEN UP your image !! 82mm century http://www.ebay.co.u...=item4ac2ff5049 x0.7 - (I have this one) http://www.ebay.co.u...=item2c6e619d66 x0.8 http://www.ebay.co.u...=item257ceca65b olympus x0.8 - I use this one too http://www.ebay.co.u...=item2ec7a0e28c I always use these on my Tecnoir 15mm rod rig to hold it all those adapters are big and heavy!

Thanks! The results from the Zomei don't look bad at all, but the picture isn't any wider... that doesn't seem to make sense :P Quote Link to comment Share on other sites More sharing options...
andy lee Posted May 16, 2013 Share Posted May 16, 2013 it will work on any Anamorphic lens - find a wide angle adapter that is bigger than the front of your anamorphic lens its that simple - you dont need diopters at all Quote Link to comment Share on other sites More sharing options...
andy lee Posted May 16, 2013 Share Posted May 16, 2013 is this wide enough and sharp enough for you?? haha! http://www.eoshd.com/comments/gallery/image/493-olympus-x08-wide-adaptor-isco-anamorphic-lens-fuji-55mm-taking-lens-nd4-filter/ Julian and Tito Ferradans 2 Quote Link to comment Share on other sites More sharing options...

tehellet Posted May 19, 2013 Share Posted May 19, 2013 I bought a BIG century optics wide angle adapter in hopes of trying it out with my Kowa for B&H. Initial tests left me baffled because I could not get ANY kind of focus. Then again, it was a test-by-hand, wasn't very scientific. But I was a little bit let down. I should try it again...

tehellet Posted May 19, 2013 Share Posted May 19, 2013 Here are some photos. The model is C11564 and came with a bayonet adapter model FA-7x80. Quote Link to comment Share on other sites More sharing options...
