richg101 Posted February 7, 2013 Share Posted February 7, 2013 wrap a bit of electrical insulation tape around the thread so it is wider, then screw into a slightly bigger step ring... the right amount of layers of tape will be nice and strong and the step ring will cut into it and form a thread.

Sebastien Farges Posted February 7, 2013 Share Posted February 7, 2013 Oups I'm sorry I bought the last clamp, apparently.... The smallest step up and/or step down ring I've found once for a isco gottingen was 52mm-30.5mm / 30.5mm-52mm http://www.flickr.com/photos/43243778@N04/8368259437/in/photostream Julian 1 Quote Link to comment Share on other sites More sharing options...
Julian Posted February 7, 2013 Author Share Posted February 7, 2013 @good idea rich! Found a 37mm to 25mm step down.. that should work with the tape and some other filters. How do you like the baby Isco Seb? Any footage? Quote Link to comment Share on other sites More sharing options...
tony wilson Posted February 7, 2013 Share Posted February 7, 2013 stan has a solution but not cheap. the same adapter as baby moller fits i here. seems to fit others as well. Quote Link to comment Share on other sites More sharing options...
Sebastien Farges Posted February 7, 2013 Share Posted February 7, 2013 I've sold baby isco anamorphot (not the same than the "iscomorphot" version, which is better) few month ago, to my opinion the baby Hypergonar is better. Here is a test between those two babies lenses : https://vimeo.com/41352674 Quote Link to comment Share on other sites More sharing options...
conTXT Posted April 7, 2013 Share Posted April 7, 2013 Greetings to everybody! @Julian Today I've came to this lens: http://goo.gl/G8EZS. Just wanted to ask you is it the same as yours. I can't see the same big Cinevision label on the lens (perhaps it is on the "dark side"), but the front looks the same to me. Thanks in advance!

Julian Posted April 7, 2013 Author Share Posted April 7, 2013 All the inscriptions look exactly the same, only the mount looks a bit different, but that might be a screw on part, just like mine has, just a different part. Quote Link to comment Share on other sites More sharing options...

Julian Posted April 28, 2013 Author Share Posted April 28, 2013 So I've had this lil' thing for a while, but didn't really use it yet. Decided to 'mount' it into a lenscap, that I put with a step up ring onto the new (smaller) Panasonic 14-42mm OIS lens (on the GH2). No vignetting from 35mm and upwards, but I was using it because of the OIS and autofocus, so I only have to guesstimate the distance on the anamorphic. It was very windy and cold.. but this is definitely the 'fastest' way of getting an anamorphic shot with any of my lenses :) http://vimeo.com/64987255 [URL=http://www.eoshd.com/comments/gallery/image/326-minimorphic1/][/URL] [URL=http://www.eoshd.com/comments/gallery/image/327-minimorphic2/][/URL] JohnBarlow 1 Quote Link to comment Share on other sites More sharing options...
tony wilson Posted April 28, 2013 Share Posted April 28, 2013 very nice work what a little gem.. seems very sharp,what what kind of stop did you have? what is it like at f2.8 or 4. with one nice test you probably upped the value by at least 300 euros :) Julian 1 Quote Link to comment Share on other sites More sharing options...
Julian Posted April 28, 2013 Author Share Posted April 28, 2013 Thanks Tony :) Don't have ND's that fit in this, have to find a solution for that, so I started at f/22 and f/16, last shots f/5.6 (maximum aperture of the 14-42mm). Did some tests with my Minolta 35mm 2.8 and 50mm 1.7 and it works fine at lower apertures I think. Will do a low light shoot soon! Quote Link to comment Share on other sites More sharing options...
Sebastien Farges Posted April 28, 2013 Share Posted April 28, 2013 That's great ! But it is not vignetting ? And apparently you did not do zoom in / out Quote Link to comment Share on other sites More sharing options...
Julian Posted April 29, 2013 Author Share Posted April 29, 2013 Thanks Seb. It vignettes on anything lower than 35mm. I zoomed a bit between 35mm and 42mm, but not during the takes. Quote Link to comment Share on other sites More sharing options...
JohnBarlow Posted April 29, 2013 Share Posted April 29, 2013 So your are manually focussing the scope and letting the back lens find its focus in free run autofocus? Quote Link to comment Share on other sites More sharing options...
Julian Posted April 29, 2013 Author Share Posted April 29, 2013 So your are manually focussing the scope and letting the back lens find its focus in free run autofocus? The camera is in AF-S (single autofocus, not continuous) I guesstimate the distance to the subject and set the anamorphic to the mark (the Petit Cinevision has marks from 0.9 meters to 7.5 meters and infinity), then I half press the shutter so the taking lens gets the focus right. I could try continuous autofocus, but then i'd have to refocus the anamorphic as well and the focus ring isn't very smooth sadly. For single AF it works fine and fast! Must faster than going into 10x zoom mode to fine tune the manual focus. Of course most shots have huge dof, but the close ups are really sharp and in focus as well. This Petit Cinevision rocks for close-ups :) Shame there aren't many OIS lenses for m43.. just the Panasonic zooms :( Would be nice to have a bright OIS prime for the BMPCC! Can't wait to try this anamorphic on the Pocket... Quote Link to comment Share on other sites More sharing options...
Julian Posted May 4, 2013 Author Share Posted May 4, 2013 Bigger apertures! http://vimeo.com/65462089 First two shots with Minolta MD 135mm f/2.8. It doesn't focus to infinity with the 135mm, only near. The other shots are all taken with the Minolta MD 35mm f/2.8, mostly at 2.8. Focussing gets difficult sometime. Corner quality is pretty poor and it vignettes a bit. Also brought the Minolta MC 58mm f/1.4 but can't get anything into focus with that lens. I should have taken my Konica Hexar 40mm f/1.8, just tried that, it's a bit soft at 1.8 (it is anyway, also without anamorphic), from f/2.8 it's very good and it doesn't vignette. I think I'm going to marry the Petit-Cinevision to the Konica :) Will try some other lenses! Quote Link to comment Share on other sites More sharing options...
tony wilson Posted May 4, 2013 Share Posted May 4, 2013 another nice video and another petit cinevision price jump i think must be worth over 600 euros now easy :) using a low power achromat will cure the softness big time.. even without achromat the anamorphic is holding up much better than the optical recipe should. some great shots in here..

brucker Posted June 30, 2013 Share Posted June 30, 2013 i've got a Cinevision 8mm coming in soon. its bigger than the petit-cinevision, so doesnt say "petit" and if it's half as nice as that video i'll be quite happy :) Quote Link to comment Share on other sites More sharing options...
Rudolf Posted June 30, 2013 Share Posted June 30, 2013 Julian, just saw your video... very nice and atmospheric! Julian 1 Quote Link to comment Share on other sites More sharing options...
