neoclass Posted June 22, 2013 Share Posted June 22, 2013 Why is that ? Only the center seems to be in focus ? Any help about this from you more experienced filmmakers ? Thanks in advance, Neoclass Link to comment Share on other sites More sharing options...
silvertonesx24 Posted June 22, 2013 Share Posted June 22, 2013 That's a property of this anamorphic, and also the reason why I got rid of it. Sharpness along the edges is terrible. neoclass 1 Link to comment Share on other sites More sharing options...
Rob Bannister Posted June 22, 2013 Share Posted June 22, 2013 I noticed the same thing but I hear diopters help this issue? Link to comment Share on other sites More sharing options...
Paulio Posted June 22, 2013 Share Posted June 22, 2013 Agreed, I owned a 7200 and was not impressed. Edges are a mess. Link to comment Share on other sites More sharing options...
silvertonesx24 Posted June 23, 2013 Share Posted June 23, 2013 I noticed the same thing but I hear diopters help this issue? Diopters effectively magnify the image, so it'd use more of the center of the lens, thus "helping", or probably more accurately- masking- the issue.

Tito Ferradans Posted June 23, 2013 Share Posted June 23, 2013 Am I the only person here who likes this lens? I'd choose it over a double focus system 95% of the time! (of course, with diopters) Zmu 1 Link to comment Share on other sites More sharing options...
JohnBarlow Posted June 23, 2013 Share Posted June 23, 2013 So why did you want to rehouse it and make it double focus.? just askin' :) Am I the only person here who likes this lens?

Tito Ferradans Posted June 23, 2013 Share Posted June 23, 2013 So why did you want to rehouse it and make it double focus.? just askin' :) Hahahaha, good point. I like it the way it is, I just think it can be improved (like almost anything else, even Iscos). And not so much "double focus" on the rehousing, but more of a "variable focus through" where the focus range isn't so limited without the diopters, nor so picky like a regular double focus lens. According to tests, you can 'set' the Panny to focus from X to Y meters, and rack focus only with the taking lens. :P Link to comment Share on other sites More sharing options...
maxmizer Posted June 24, 2013 Share Posted June 24, 2013 Why is that ? Only the center seems to be in focus ? Any help about this from you more experienced filmmakers ? Thanks in advance, Neoclass as everyone knows LA7200 was built for AG DVX ... is not compatible with all lenses, is not compatible above the approximately 50mm, is not compatible with some lenses because, the distance between the objective lens and the lens of the LA7200 is too high (this is improved by putting a diopter from 0.25 or 0.50 between the lens and LA7200 http://www.youtube.com/watch?v=ci_PM-g1K6c&list=SP219BA51EFE970B89&index=54 ). What goes well with: Panasonic is the best: 20mm F.1.7 but well with Canon 24-70 f2.8 or Sigma 24-70 f 2.8 Tokina 11-16 just try it If you want, we do list, where it works well and where not ;) neoclass and Tito Ferradans 2 Link to comment Share on other sites More sharing options...
Tito Ferradans Posted June 24, 2013 Share Posted June 24, 2013 I gotta get back my 0.25 diopter to test this! Along the last year I've read multiple times that diopters between the anamorphic and taking lens would not work properly... I just got confused about maximum focusing distance (maybe I missed a line or so of what he said). It's limited within the diopter range, right? ps - the LA7200 also performs very well combined with Canon 16-35mm f/2.8 Link to comment Share on other sites More sharing options...
maxmizer Posted June 26, 2013 Share Posted June 26, 2013 tferradans try to put the reverse the diopters Link to comment Share on other sites More sharing options...
neoclass Posted July 23, 2013 Author Share Posted July 23, 2013 Maxmizer Vmax I've seen many videos with the same gear I use and they show no blurry edges. Watch. for example, Nitzberg's vid of LA7200 on Vimeo. All clear ! neoclass 1 Link to comment Share on other sites More sharing options...
Paulio Posted July 24, 2013 Share Posted July 24, 2013 Using a achromat and not just a diopter may cleanup some of the chromatic ass the LA7200 is full of, not sure. My understanding is the limitation is quality of the optics in the LA7200. Link to comment Share on other sites More sharing options...
Tito Ferradans Posted July 24, 2013 Share Posted July 24, 2013 Tested the +0.25 diopter thing, and it worked great for close focus, from about 1m to 2-3m. I still don't understand how this happens, optically, but it DOES work. Link to comment Share on other sites More sharing options...
