Zeek Earl Posted September 12, 2012 Share Posted September 12, 2012 I'm in the market for an anamorphic setup and my question concerns diopters and anamorphic adapters like the Panasonic LA7200. Most of the diopters I see being mentioned seem to go in front of the anamorphic adapter, and I have seen an an example of a guy velcro-ing 82mm close up lenses on top of the Panasonic adapter. So my question is, why can't you put a smaller diopter behind the adapter, between the anamorphic adapter and the lens? For example I have a prime set of Nikon Ai-S lenses with 52mm rings on the front. Couldn't I just get some 52mm close up adapters, put those on the lenses, and then attach the anamorphic adapter? (something like this?[url="http://www.bhphotovideo.com/c/product/855633-REG/Polaroid_PLFILDCCL52_52mm_Close_Up_Lens.html"]http://www.bhphotovi...se_Up_Lens.html[/url]) Anyone know or have experience with this? Thanks so much Zeek Quote Link to comment Share on other sites More sharing options...
QuickHitRecord Posted September 12, 2012 Share Posted September 12, 2012 Typically, it isn't your lens that needs the diopter's magnification. It's the projector lens. Your camera lens can probably focus as close as 2' or 3', but the projector lens is designed to focus on a movie screen 20' to 50' away. If you put the diopter between the two lenses, the anamorphic does not get any of the benefit. You'd be focusing sharp and close on a blurry image. The slight exception to this that I know of is the LA7200, behind which you can place a very weak +0.25 diopter to help the edges be a little less soft. But you can also accomplish this by using a longer focal length on your taking lens as well. Quote Link to comment Share on other sites More sharing options...

tony wilson Posted September 13, 2012 Share Posted September 13, 2012 please don't waste money on made in china close up's. they are crap. buy used stuff on ebay vintage japanese is always better than new crap like those close up's. anamorphics do not need +3 diopters mild low numbers are of interest Quote Link to comment Share on other sites More sharing options...
roccoforte Posted September 15, 2012 Share Posted September 15, 2012 Thanks for the replies. I'm new to this, so any info is extremely helpful. Upon further inspection, I think I am the problem and not the lens (thankfully) but here are three stills from video I shot in my kitchen with ambient lighting and some post color correction. Aprox 2 feet away, 50mm can't recall the f stop) - http://imgur.com/a/iv8oD - That's as sharp as I can get it, and from these stills they don't look too bad actually. Any thoughts?

QuickHitRecord Posted September 15, 2012 Share Posted September 15, 2012 They look pretty good to me! I wouldn't call this a "soft" lens at all. Quote Link to comment Share on other sites More sharing options...
