Panasonic AG-LA7200 diopter mounting solution

[QuickHitRecord]

I did mention this in another thread, but I think that it probably deserves its own topic.

For those of you trying to mount diopters on LA7200 anamorphic lenses, this is what I have been doing (see pictures).

The binding product is called Dual Lock. It is similar to velcro but is adhesive-sided and creates a stronger bond. I never have to worry about my diopters slipping off. It works well with inexpensive Cokin-P diopters as pictured. With a GH2, I can shoot with the Voigtlander Nokton and the LA7200 with only slight vignetting. So 30mm and up should be vignette free.

It's a very simple concept but I haven't seen anyone else using it and it took me a while to figure it out. I hope that others find it useful.

Good approach.

The 3M Dual Lock is exceptionally strong, costs more than Velcro but is ten times as strong (that's being conservative).

Hello, I'm a little doubt arises, The Cokin Close Up +1 A101 are too small right? And these ( http://www.ebay.es/itm/KOOD-P-Series-Close-Up-1-Macro-Filter-Fits-Cokin-/200608019419?pt=UK_CamerasPhoto_CameraAccessories_CameraLensesFilters_JN&hash=item2eb52b73db ) are well-adjusted? Regards

I have never used with a Cokin A-series filter, only P-series. The item in your link seems like it would work since it seems to be P-series size.

interesting setup thanks for sharing
would matte box that hold filters be an option too?
or would the filter be too far away from the lens

I suppose it's possible, but the LA7200 already has sort of a matte-box shape, so it might be tricky to get the filters close to the front glass. Also, do they even make square close up filters?

Mark at EyePatch films did a YouTube tutorial about using a Cinetactics Anamorphic Matteblox a while back. I've tried it out and I much prefer the solution above -- it is much cheaper and you can get the diopter closer to the glass.

thats a good way, how i did mine was put a line of velcro on the bottom and top so the Cokin - P slips inside and closer to the glass

where did you guys buy the cokin p diopters?

 

thanks

[teh]

And whats the widest focal lengths before these diopters will couse vignetting? 

[Tim]

Why not screw the diopter to the la7200's 72mm thread?

Is it so you can quickly change diopters?

[soupkitchen]

you want the diopter in front of the anamorphic rather than behind. That's the problem

138mm +0.5 diopter for $100
Ending soon. :)

[Tim]

Would this be suitable for the la7200?

Tim, I'd avoid this one, since is too small for the front of the LA7200, and this bayonet mounting is a bit confusing. It doesn't work in regular filter threads, you'd have to adapt.

 

Try this one, it's cheaper, and way bigger

I'm searching for a +.50 diopter for the la7200, I figured I'd do with the Cokin P series for the +1
