AG-7200 (AG7200) Anamorphic Lens Discussion and Footage

why would you need diopters for ? it's a zoom through unit so you can focus much closer than an isco/kowa already.

i am going to ask again. any way to place diopters in front

Not in front, but you can put one behind it - personally I haven't had much luck yet with diopters on mine, however - at that point we're talking about a lot of optical elements being combined and it just seems to cause problems - the Panny adapter seems to really have a sweet spot when the subject is sort of moderately placed within the focusing range - i.e. 4-6 ft away, closer there are issues, further there are issues (smearing on the edges depending on the lens and f-stop, but I love mine you just have to work within its sweet spot.

They weren't hard to locate when I bought mine a couple months ago. I suspect Mr. Bloom is gonna make them a lot harder to acquire soon (either that or eBay's gonna flood with LA7200's after he dislikes it and buys an Isco instead, lol).

mr bloom is a very clever talented man and a great marketeer,he choose panasonic because they are the only monied game in town.
do not worry folks.a warehouse is primed with dusty old stock ag 7200s.
panasonic and b&H cannot believe it.
dead stock they thought would have to be put into a fire sale is reanimated into a must have f5.6 motion picture tool.
no point in going the old iscorama route. nobody will give him one for free and he is not going to pay his own hard cash to promote a dead product line.
it will be interesting to see the motion picture.
little bloom and his struggle with achromatism, chromatic distortion on planet panasonic.

..., you can expect the LA7200 to trade for crazy prices in the future, when it goes out of stock on B&H...

We are almost there. An AG-LA7200 got sold on ebay for as much as $830 today. I think new it costs $850. Soon we'll be seing isorama prices on these lenses :2vrolijk_08:
 
hi, i have found some cheap Panasonic AG-LA7200G lenses.

is there a real difference between the AG-LA7200G and the AG-LA7200, or ist it just the name?

thanks

Got some more footage here... above is a storyboard/lighting/acting rehearsal for an upcoming feature I shot using the AG-LA7200. Specs as follows:

*Canon 5d Mark II @ 24p - transcoded to prores - FCP
*Panasonic Anamorphic Adapter (AG-LA7200) mounted on:
Nikon 28-70mm f2.8 zoom
Pentagon 135mm f2.8

Enjoy!

PS Leon, I don't think there is a difference between the 7200 and the 7200G, though I could be mistaken. I seem to remember reading somewhere there isn't a difference.
 
you need to close lens to get focus on this adapter.
I disassembled other 1.33 adapter and moved front and rear glass closer to each other so i dont need to close lens and i have focus BUT stretch ratio is now like 1.2 not 1.33.

Thats the nature of anamorphic lenses,if glasses are closer to each other then stretch ratio is different and things are less stretched,thats why people are "fatter" on closeups.

Okay, so I'd been getting a lot of questions on how to attach the LA7200 to your lenses and decided to make a tutorial about it which is now online. This is a really simple thing to do once you know how to do it, but I just keep constantly getting the same questions, so hopefully this video will make all of this clear.

Teresofblood, in the video I do have a 72-77mm step-down ring, it works fine. You can pick them up at any place that sells step-up/down rings... like ebay.

Also at the end of the video is a nice test comparison between the coverage differences between the regular lens and it's anamorphized counterpart.

Hopefully I didn't leave anything out. Enjoy!

I really like your tutorial - very helpful! A quick question for you. I currently have a 62 - 72 step up ring for my GH1 LA7200 combo. Do you know if adding a glassless filter (72mm) to my current chain will suffice? Or is the 72 - 77 the only workaround?

Thanks again for the tutorial,

Trey
 
Glad it was helpful! Yes, a glassless 72mm will work perfectly. The only instance imaginable were it wouldn't is if it's an ultra slim filter... but any cheap standard UV will be plenty thick.
 
Hey everyone, have yet another test here. This time comparing a Lomo anamorphic zoom lens with the AG-7200 on a 35mm flektogon on the 7d. This is a pretty mundane test, nothing scientific. I actually missed focus a few times on some of the shots, so my apologies in advance!

http://vimeo.com/14871927


I've been using the 5d for previous anamorphic stuff, but since the LOMO was designed to fill the ff 35mm 4:3 academy ratio, it allowed me to simply have to crop the sides in post to achieve 2:35. On the 5d the top and sides have to be trimmed a little with the lomo resulting in resizing odd pixel dimensions. Having used the lomo and Ag7200 on the 5d though, I find the 5d resolves simply waaay more detail than the 7d. Maybe one day soon I'll directly compare both of these lenses on the 5d. Enjoy!
 
I just finished moving, so I was finally able to dig out my camera stuff and play with this again. I found a 77/72 step ring and attached my AG7200 to my 7d, with a Canon 17-55mm IS. Strangely, I get vignetting all through the zoom range, but only slightly dim corners toward the 55 end. I've seen many people say it is easy to get rid of vignetting with much wider lenses than mine, and they often used broken filters, which would be thicker than my step ring, so I'm going to look deeper into this and mess around later.

CS5 makes editing anamorphic 2.35 easy!
 
Strange! I don't get any vignetting with the LA7200 on the 550d at focal lengths above ~24mm (Canon EF-S 15-85 f 3.5 - 5.6). At 15mm (if you need to go that wide) there is vigneting but would still be useable if you crop the sides. I use 2 step up rings to attach the lens too.
 
Thanks for the input. The thing I've been keeping in mind is, IF I was to use this on a project, the vignetting would likely be contained outside the TV safe area.

I'll mess around more tonight.
 
So I realized my problem. I found that my 17-55 performed well at 28 and 35 and f/5.6 as long as the lens is focused on a subject far away. I see vignetting all through the barrel, unless I focus to the far end of the lens. Then the edges are slightly dim, but probably wouldn't be visible on a TV, due to the safe area.

I don't think it would be realistic to shoot an entire project with this, as it's too limiting in terms of fstop, focal length and subject distance. It'd great for wider shots, but for closeups, it probably would be better to crop. This is by no means a definitive statement, just a basic observation from the small amount of tests I've done.
 
The lens doesn't perform well in terms of sharpness with longer lenses (85mm or 100mm for instance). Definitely better to crop for close ups.
 
I've seen stills from a movie shot on 5DmkII and LA7200 being tacksharp troughout the whole image. The guy incidentally found the Sigma 24-70mm 2.8 being significantely better than the (supposedly better) Nikon equivalent lens he used before.
Does anyone have experience with the LA7200 with the Sigma 24-70 2.8?
I've also seen a test with and without +.5 diopter and the diopter turned the image from unusable to sharp. Did anyone had similar findings when using diopters?

I'll get a 7200 soon and will try out myself, but maybe you guys have some experience to share about this.

I've seen those stills, too as well as test reel available on vimeo:

Very impressive. Wonder how close he's able to focus. Looking at that 'test reel' fence shot, it seems like he gets pretty close.
I've just pulled the trigger on this 24-70 Sigma lens... Hope it's gonna do the job well. If not, I needed normal zoom for family photos anyway ;)
Will try it with 7d during location scouting next week (don't have 5d2). I got high quality two-element +0.5 diopter, too - if I'm able to mount it on LA7200 somehow, will check if it allows for closer focusing/wider aperture, like some test suggest.

TeresofBlood you have vignetting probably because of rings, try to take them out and just hold anamorphic in front of your lens to see if you still have have vignetting without any rings on anamorphic or SLR lens, try to find the lens which would allow anamorphic rear glass to be as close as possible to front glass of SLR lens.
To use this lens without need to stop down SLR lens and focus closer you have to disassemble anamorphic lens and move front glass closer to rear glass ,cause this lens is setup to use with small sensors and wide glasses ,you need to move the glass but this will change squeeze ratio slightly and you might get 1.2 not 1.33 .
