Timotheus

After long deliberations with myself I decided to let my ISCORAMA 42 MC go, because freelance life can get a bit tough in winter months, especially with the tax payments here in UK.
The lens is in near new condition, probably one of the best you’ll ever come across. Body has almost no signs of use. Focus ring and all the markings have no visible wear.
There are NO scratches, marks, haze or fungus outside or inside the optics. As with every vintage lens there are a few tiny dust specs inside. They won’t affect the image quality in the any way and most people wouldn’t even mention them, but I want to be as honest as possible.
Focusing ring is super smooth, feels like new. Many ISCORAMAs 42 do not have the rubber grip on the alignment ring. This one has and it also has no visible wear.
The lens comes with front and back caps, 82mm skylight filter (which was protecting the front element from scratches) and 82mm to 77mm step-down ring.
I’ve recently added a seamless “compression fit” follow focus gear to this lens (I've added a few updated pics), which will also be including as part of the sale.
I’m looking to get £2500 for this lens. I’m hoping to sell it locally (London, UK) but will considering sending it anywhere. Shipping and paypal/currency conversion fees to be paid by the buyer.
Another one of these was sold for a similar price on ebay just a few days ago and it wasn’t in such conditions, so I believe I’m offering it at quite a good price.
I absolutely love this lens and will be posting my review online soon, but I do not want to do it just yet because I don’t people to think I’m being biased just to sell the lens.
I know that I'm a newbie on this forum, but I've been a long time reader and I'm quite active online in general, so people like Tito and hopefully a few others could certainly vouch for me.
Oh and here are 2 test videos I shot with this lens so far.

Last week I had an insight into just how responsive Sony are becoming in rolling out support for their cameras. As users like myself and Paul Antico discovered soon after the FS5 was released the image had some issues. The very week I bought my camera Sony were in touch by email - I was then tasked to shoot some tests and send the XAVC footage to their engineers in Japan so they could work on analysing the problem. The detective work complete, Sony have now just released a statement saying they've identified the bugs and will squash these in upcoming firmware updates.

Hello guys, 
I'm creating this post to share something I did for myself to help me understand the difference between the original aspect ratio and end aspect ratio after de-squeeze with the different anamorphic lenses. 
Maybe it will be helpful for someone else. 
You can download it for mac of pc here http://www.sandrobrt.com/ratio-comparison-tool

They also have a NX500 with kitlens for 449. Only seller yet with these prices though.
With all the love going around here for this somewhat tragic camera, I thought I'd mention this as an indication where prices may be going. Looks like patience is paying off for potential buyers, at least in the regions where Samsung announnced discontinuation. 

review of SLR Magic's achromats, I thought it could be useful here.

Saw it opening night last week after ordering tickets like 3 months ago... Never did that before, ha.
Really great moviegoing experience: cheers and applause from the audience, a great atmosphere. And the film totally earned it, I feel. Yeah, the plot is quite similar to Ep. IV but they nailed the characters, I cared for 'em and the film is just good fun. Very much looking forward to the next one.

Hi all,
Inspired by Tito and Bold and their anamorphic Lens-cyclopedia, I decided to try and make a list of low power diopters useful for anamorphic video. Using the info in this thread and searching on the web, I compiled a list which may be useful for anyone looking for suitable diopters.
I've attached the list as PDF. Feel free to comment and/or correct. The list may (hopefully) end up as an add-on to the online Lens-cyclopedia.

Hi guys,
Added these to the list. Great finds Ken! Couldn't resist buying that 77mm KMZ diopter on eBay for a steal...was the last one (for now)!
Cheers,
Tim

Timotheus, we also have a +1.8 Achromatic Diopter in 77mm for our Anamorphot lenses. Thx!

they are doublets. my review about them is coming in two weeks.
I bought THE EXACT same ones you did. It was a great price, right? Too low to let it pass for two doublets.

IMO, that is pricey.
I also bought the SLR's +0.33 &+1.33 set already.  http://www.ebay.com/itm/271994594777
I think they are double element too.

Well done, man! +0.25 is hard to get!
I have this minolta, it's almost the same as the Tokina +0.4, except it's +0.33
http://www.ebay.com/itm/111827493087

Just got this one http://www.ebay.com/itm/161898434253 , very happy with it. 
It is a new item. Looks like a good deal compare to original price.

Great list! You might want to add the Marumi DHG Achromat Macro Lens 330 (+3) and (+5) Very good quality. Come in 72mm and are achromat doublets. Also a Polaroid 250D Close Up Lens (72mm) which is a +2 achromat doublet. Redstan made a +0.25 achromatic doublet but you might not want to add it to your list being he made 8. I have one and it's incredible. I hope he makes more because when you put it in front of the SRL Magic rangefinder it does wonders  

I found f-1734 is a good deal, 77mm.  some one said is 0.6 (means from 1734mm).  but the glass is almost flat (heavy, thick ring), compared to my vivitar 1/2, 62mm, very curved.

Optics is mostly simple, with some occasional complexity thrown in to make it interesting.  In fact, I've almost completely forgotten all the fancy math I learned after high school, since by and large all the math you need to know to be a successful lens designer is geometry, trigonometry, and a bit of algebra.
In your case, assuming that the anamorphic portion is working at infinity (i.e., parallel light in and parallel light out) the aperture of the optical system is determined by the diameter of the iris diaphragm in the taking lens *unless* there is some other limiting aperture in the system.  Imagine that you take a pin and poke a tiny hole in a large piece of aluminum foil.  Next, open the f/1.2 taking lens wide open and place the aluminum foil in front of your Rectilux so that the pinhole is centered on the optical axis.  Clearly, in this case the f/# of your lens system is determined by the diameter of the pinhole and not by the diameter of the taking lens' iris diaphragm.  So we would say that the pinhole is the limiting aperture in your lens system.
In your case the clear aperture of the back of the anamorphic section is 43mm in diameter (assuming it is round and not rectangular).  This means that the collimated on-axis beam of light exiting your anamorphic section cannot exceed 43mm in diameter, and may be less if any of the other optical surfaces in the Rectilux or your anamorphic group are limiting apertures.  The entrance pupil diameter of your 85mm f/1.2 taking lens (most likely 1/3 stop faster than f/1.4, or f/1.2599 in reality) is 85/1.2599 = 67.5mm.  Since 67.5mm is bigger than 43mm you are underfilling the entrance pupil of the taking lens.  As a consequence, you could stop down the taking lens until its entrance pupil is reduced to 43mm, and have no impact on the actual f/# of the system.  In your case, the actual maximum f/# would be f/(85/43) = f/1.98 ~ f/2, and not f/1.2.  Again, this assumes that the limiting aperture of the system is the rear aperture of the anamorph, and not some other surface in the Rectilux or the anamorph.  If either of the latter is true then your true f/# would be slower than f/2.

Just a bump for this topic to remind you of this great deal :-) Cashback offer ends today. It's a UK promotion but you can apply for the cashback EU-wide.
Very much enjoying my new G7.

Great work TIm!  I added a copy of the spreadsheet to the Lens-cylopedia!

Hello all,
Tito has kindly allowed me to do some streamlining of the Lens-yclopedia database:
I have templatized all the entries so key information is in the same location when you cycle through the pages. The template improves overall readability of the information. I've broken up Mounting Solutions into To Filter, To Taking Lens, and Lens Support I’ve changed the Index to a spreadsheet that provides key stats for easy ‘comparison shopping’ I’ve removed a couple lens entries that had no (or next to no) information. I've added a few bits of info on various lenses as I went through, particularly links to example footage. I’ve made significant updates to the B&H and B&L entries based on the info I gathered from EOSHD, as well as other locations. I'll keep adding to them as I embark on modding/using my lenses. Check out the updated Lens-yclopedia here. A great big huge thanks to Tito for allowing me to build on his great work.  And to all the folks who have responded to my info-seeking posts.  The information people have provided here has been invaluable for a newcomer like me.
I was surprised at how much info I was able to find on the B&L, I cited sources in the Lens-yclopedia entry where I could - I would love to see all entries given source/reference links. I know people’s time is limited, but even just a morsel of info here & there would really help re-invigorate the database and make it more robust.  A little crowd-sourcing can go a long way!
I am considering periodically starting ‘Seeking Info About X Lens” threads to build up the other lens entries in the Lens-cyclopedia.  If this is something you would like to see (or help me with), please chime in.  
If you want to send info my way (corrections, answers to red question marks, Lens-yclopedia functionality, etc), I will find time to update the database appropriately.
Cheers,
