nice lens, really sharp image, as long as you're got a rail system prepared to support it
-
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.

Investigating the recent Isocrama 36 that went for $4,600 on ebay as I received an email saying that it was up for a "second chance" purchase as I bid on it for about half of the final bidding price.
http://www.ebay.com/itm/200926249978?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648
There is also a private bidder with little to no history named (o***u
) who bid on these two items and another similar lens for a very high price that might be driving these prices up to scam money from everyone.Here is the second Isocrama 36 that was "sold" for a high price
http://www.ebay.com/itm/261226754104?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648
I emailed back the first lens seller who I originally bid on to see if they would reply and find out more regarding why he is offering me the lens for a lower price.
Will post feedback on these items....hope this will give everyone some insight to ebay Isocrama purchasing online as it is a hunting ground for possible scams when dealing with these item prices.
Sounds like a common scam

Never heard of anyone renting out anamorphic lenses, you'd probably be better off buying then selling when you're done with it, and you can get plenty of workable options for sub-$1000- Kowa, b&h, Isco, Schneider, etc.
If you're shooting with a 1DC I'd recommend LA7200 even if it isn't sharp as the ones above it works with much wider focal lengths which is important with full frame cameras.
-
Yes this a good lens if you want pure sharpness, probably the sharpest one from my experience. It's big though, definitely need a rail system for support.
-
Out of curiosity do any of you guys know the use of the backup lens? Does it have a practical use for dslr owners (if not, no worries, it's weight makes it a fantastic paper weight or book-end).
No practical use. Paperweight

Hi everyone!
I've recently started to work on this project that might interest other users in this forum. I'll need some help in the process. One of my main interests in this development is to keep the whole process "open-source" so anyone can reproduce the rehousing based on what we share in this topic, staying as far as possible from a monopoly with ultra-high prices! :D
We must agree that the Panasonic LA7200 is an interesting lens, right? But, as all others, it has its quirks and downsides, mostly related to its body design.
Plastic is just cheap and fragile. It's very easy to lose parts of it (tiny screws, mostly), not mentioning the deep thread that requires more step rings and the square-front which makes diopter use way more complex than should be. Also, its weakness for close focus or shallow apertures is very well known.
What if all this could be solved in a big move? What I'm planning is a full rehousing of this lens, improving every aspect mentioned in the previous lines.
- Round, full-metal body
- Internal alignment mechanism based on three screws instead of one (like a clamp)
- 67mm, exposed rear thread
- 114mm front thread, with various step-downs that won't increase the distance from the front element (non-standard design)
- Very easy to remove glass for cleaning
- "Focus adjustable", based on a push-pull concept, for closer focus, or longer rack focusing.
Sounds good?
What else do you guys think could/must be improved?
I already have multiple sketches around these ideas but haven't started precise modelling yet, nor have contact with any CNC owners that might be interested in the project.
If anyone wants to partner, please, speak up!
My direct email is ferradans at gmail.com
ps - the focus part is mostly based on this video, but with a body around it! hahahahttps://vimeo.com/23042151
I built something like this video a few years ago. It was pretty easy, just cut the LA7200 and then use a macro focusing rail and some screws to mount the outer part. I was able to focus within a foot or two, but eventually gave up on the LA7200 altogether as I found the lack of sharpness unusable.
-
Wow, thanks guys! I'll go research the Schneider Isco's as I haven't read about those yet.
@silvertonesx24: Any links to a diopter that would work with this? The front element is massive and I can't imagine anything smaller that 105mm covering it.
@andy lee: Thanks for the tip that Tecnoir looks nice. I don't currently own a rail system so this is a very nice excuse to buy one. Any chance you have some footage of something you've shot over the years with 1 of these lenses?
@both: Silly question, please forgive my Anamorphic newbness. The smallest focal range is 17ft (so it says on the lens) with a +0.5 diopter, does that cut that range in half? How do you do the math? I ask cause I see a lot of +1, +2, etc. close up lenses, but most on this forum recommend +0.5.
Thanks for all your help!!!!
Regarding the diopter, I would start with these for cheap. 82mm threads. 86mm might work too.
http://www.amazon.com/82mm-Close-Up-Filter-Diopters-Magnificatoin/dp/B008HSAGXI/
Regarding the math, I honestly have no idea how that works. A +.5 or +.4 diopter is going to be rare though and much more expensive than +1.
With some of my taking lenses I know I've focused sharply just under 10 feet with these. I haven't done any official tests though.
-
A vid anamorphic clamp and some rail supports will mount this nicely. I don't know much of the history of this lens except that all variations of this lens (Isco Gottingen, Schneider Isco, Iscorama, etc) are all optically and mechanically identical as far as I've seen. They were used by movie theaters on film projectors and cost around $4000 when new.
The anamorphic image you get from this will be very sharp, even wide open. You won't get any flares as it is multi-coated. It's pretty easy to drop a diopter in the front barrel for closer focus.
The only big downside is the size and weight.
-
Should have stated- full frame. Anamorphic- a variety of 2x lenses. I'm pretty well covered with the 58mm Helios, just would like something longer for the B+H anamorphic which vignettes
-
I know the Helios 58mm is a very popular one for anamorphic shooting, I was just wondering if anyone had any recommendations in the 100mm+ range for anamorphic lenses that vignette.
-
There are some real opportunists out there, starting an auction bidding at $3k for the Iscorama 54.
I'm a bit concerned on the effect this thread is having on auction bidding.
Would it be a huge loss to the forum if I close this? Looking for opinions.
It may be driving up the prices. But you have to take the good with the bad I suppose. Perhaps an anamorphics from ebay testing thread would be better.
I purchased a B & H anamorphic because of a member here who did a nice test and snapped some pictures of the setup in this thread.
-
Also, I put in a bid on this, was told I won, and was asked to pay with Western Union (which I would never do) and said I'd only pay with Paypal. Seller asked a few questions about currency conversion, getting money from Paypal to bank, etc, and I told him that it'd probably just be better to go with the guy from Italy that he mentioned to me as it sounded like an easier transaction.
BTW, I don't think you'd ever need to do a BIN ebay auction as Andrew suggested. From my experience, paying with a credit card through Paypal is double protection.
-
But also, i do suppose that's what such forums do to prices:
I bought something for £50, posted a video on Vimeo & the next time it came up on ebay it went for £300+.
I know someone else here has posted something with the same lens & i fear for the next time one of these lenses appears!
Price is all relative, but it ain't worth more than £150-200.
Anamorphic prices are completely unpredictable. There's no baseline, it's really just which one has the best looking production in it's demo video (which include much more than just the lens of course). You pay extra for a researched lens with a slick video vs. something that no one has ever tried before, as there's more risk in knowing what you're getting.
-
I have one of these- a half-coated one that can shoot around f/2.0 that's usable and sharp enough. It's a great concept, but really I've had a hard time using it for anything other than tests, because of the focusing mechanism (or lack thereof)
-
Yeah, I've got some money put aside specifically for the EF -> MFT Speedbooster. Why don't they want my money?
Exact same thing here...
-
Looks like Amazon Prime ran out of 64gb Komputerbay cards. Lol.
-
Andrew, the sample footage in the OP is broken.
I am a ML donor, does that mean that I have access to this daily firmware? I have only 600x cards though. At least those will only get faster and cheaper.
-
Great writeup, Andrew. I thought your posts on the original BMCC were much too defensive and I greatly prefer this pragamatic, disinterested view.
I guess that's because personally I am trying not to get too hyped up over cameras any longer. If there's anything I've learned over the past few years, it's that people who buy the latest generation are getting burned faster and faster. Even as a professional paid very well for my work I can't see spending more than $2k at best on new camera technology. Just look at a $500 hacked GH2 + $400 speed booster (if that ever comes out) and drop the rest on glass and accessories as you see fit. Maybe I'll get a Production Camera next year, or the year after, and meanwhile I continue to invest in glass.
Also, why is everyone so keen to get some C mount glass on the Pocket Cam? All of the C mount stuff I tried years ago on my GH1 was optically garbage and every piece I had was eventually sold off.

Between
44m-4
and
44m-2
Is the 44m-4 better because I can get the anamorphic closer to the taking lenses?

no longer available

Million dollar blah blah blah. So you're suggesting the reason Aronofsky movies are good is because they are expensive. If you look at the way he conceived of and shot Black Sawn I think you'd change your mind! I'm not against your argument for shallow DOF and good cinematography giving a low budget shoot a higher production quality and DSLRs are great for this. Your conclusion about me being some kind of apologist for the BMCC is way out of order though. It is superior technology.
No, I'm suggesting that his budgets allow him to work around big problems that we in many cases cant. Need to shoot in a car or a small office on a 2.7x crop? No problem for Mr. Aronofsky, knock down a wall, build a set, use a complicated rig or a rare and expensive lens. We usually don't have these options and have to rely on DOF and full frame to make the best of tight situations. As lousy as the 5D codec is, there's no way the BMCC would replace it for me. l enjoy the 35mm Zeiss + 5D look for subjects and raw isn't needed for most clients. My cinematographer can make up for dynamic range. So for now, I don't find it to be superior, and especially with the shipping issues, I'll wait.
-
Like I say if a 2.7x crop is good enough for Darren Aronofsky then 2.3x is good enough for you. Super 16mm films have won multiple Oscars throughout history and nobody complained about the lack of shallow DOF or the film stock being ludicrous! Do you realise how silly it sounds?
I'm not sure how this is relavant. Darren Aronofsky has million dollar budgets, million dollar talent, million dollar locations backing him up and helping him work around problems. I'm as tired of the 5D 50mm 1.4 focus-searching look as anyone, but I'll admit it's saved me more than a few times when trying to give a cramped dingy doctor's office a quality cinematic look, which most clients associate first with shallow DOF and next with good cinematograpy. I was very tempted by the camera, but this was my main consideration into deciding to invest $4000-5000 (BMCC plus mandatory computer and storage upgrades) in quality glass instead.
I'll wait for v2, or something from a different manufacturer. It'd be nice to have a camera dedicated to ProRes 444.
Also I agree with the sentiment that this blog has gotten way too defensive of BMCC lately.

Nice stills. I really enjoy the 2x anamorphic bokeh, and a carnival is a perfect location to showcase that.
