This was taken with ISCO Ultra Star.

Be careful, built with plastic, including lens.

What is difficult?  The best way is using flare, with grid setting on viewing screen, to see the flare whether is horizontal.  But if really no flare, you just take circle/square/rectangle object, can easy to find distortion after decompressed.

Nothing to do with fps.   To use 2X anamorphic lens, 4:3 video is the best ratio.

Thanks for your input!  My taking lens is an 85mm Nikkor.  I shoot with a Nikon d750.  Do you have better recommendations?  On my full frame, I am worried about vignetting with anything wider than 85mm....thanks again.

IMO, this lens should work with 100mm to complete avoid vignetting.  And since it is not easy to use as dual focus, focus ring is needed.  FM(Focus Module) was design for it.   

BTW, 16H/8Z/ELMOSCOPE II are perfect for 85mm without vignetting.

Where did you buy that black "for telephoto Lens hood 58mm" part ? What is it exactly ? I can't find it on google.

Ebay, search for these key words!

I just ordered one like the one on the right of the photo. Now I need a clamp. I don't know what to buy. My taking lens has a 52mm thread, but I might use another taking lens in the future.

My mounting way for 58mm filter thread (Canon 85mm f1.8) taking lens is here.

BTW, this lens is easy to add(glue a step up ring) non-rotating filter thread for CPL

usually, red one is more expensive.  I sold mine earlier.  And red one has the least flare due to its coating.   following all pictures were from my lenses.

Totally different shape.  Big one’s front glass is much bigger.  So adding filter is not easy, need 82mm or above I think.
Theoretically, big one has higher resolution.

I posted both samples before.

Hi, I can tell you this one is exactly renamed 16D.

16H and D, the difference is only view angle.  the front and rear glasses size are almost same.  I never own S.  But looks it is close to D.  might be a little bit wider.

Dude, does the 62mm step up fit on the Isco´s threads??

Yes.  Perfectly.

Here's the lens and the metal indentations.

Looks like this lens was modified somewhere.   There are some little screws which can disassemble all parts.   I also mods it as no lock(re-drilled holes to make it) .   The rear big ring is not necessary.  It was for adapting to around 71mm(70.65?) projector lens.

Hi guys. I'm new to anamorphic & would like to ask for your opinion about an Isco Ultrastar light gold (1st version) that I'm buying. According to the buyer, the focus ring does not turn & is fixed this way. It is set to infinity. Is there a version of this lens that is locked? Is this normal? Also, the rear end of the lens body has metal indentations due to the screw of the clamp digging in to the metal. If that is the case, is this something that will stop you from buying the lens. I'd really appreciate your thoughts on this. Thank you.

Post a photo to have a look.

I also like to mount this anamorphic lens and take photos vertically.  So just looks as normal, not widescreen. ?

1. F1.8

2. F5.6 (to get good flare, need to use small aperture)

I am pretty sure Kowa B&H, 16H, 8Z and Elmoscope II (there are other re-branded name too) have the same optical glasses.  Only difference are rear diameter, distance marks(only Elmo use metric system, so I keep it) and coatings, actually two color amount them.  

Except 8Z, I owned all other three before.  I don't know why B&H's price is higher.  So I sold it.  Its rear diameter is bigger, so unable to mount closer to some lens.  I also like metric system.

Thank you guys for the answers! 

I didn't start searching for kowa or other lenses because I've read that you can't shoot under f/5.6 for example.

Low light performance is important for me, so I excluded kowa, sankor(am I wrong?) & SLR.

As I understand, there are important differences in golden ISCO lenses with Ultra Star or Blue Star. 

 

 

I don't think so.  Here are samples of Elmoscope II (=16H)with Canon 6D, 85mm f1.8 lens @f1.8.

I looked up and found some Schneider Cinelux lenses. I have read that ISCO build better ones for my use. Still I'm interested in Schneider because there are so many on ebay. Do you have experience with both?

Here from Schneider: https://www.ebay.de/itm/Schneider-Kreuznach-Super-Cinelux-Anamorphic-MC-2X-Anamorphic-Lens-Cinemascope/264457325410?hash=item3d92e28b62:g:JzkAAOSwqYxdGM4c

What would you choose? 

 

This is older model.  need to modify to use with FM single focus lens.

Schneider Cinelux lens are unable to use as double focus.  But it is perfect to fit with FM lens.  http://anamorphicshop.com/product/fm-lens/

But they like ISCO, very sharp with poorer flares(so I think golden anamorphic lens has the same characters).  Maybe older model's flare has a little bit better.  I found their coatings are not exactly the same.

The min focus distance is 1.5m.  if you want flares, just forget all golden lenses.  ?

I can tell you a little bit.  

1. same as 3, but might be different in coating.  it is multi-color coating.

2. earlier version.  IMO, 1 & 3 are better.  If I remember correctly, its front rotating.

3. If I remember correctly, coating is green, more flare than 1.

All of them can be used on full frame camera(3:2 photo mode) with 100mm lens without vignette at infinity.  

Usually, various single focus solutions has no focal length changed, which is insignificant. 

My way has more changed.  ?

 maybe no lock if not seen “lock” mark.  Not every lens has it.

never own this lens, usually to lock/unlock focus ring by push and pull front part.

What I mean is this lens is a better choice comparing to this video:

BTW, from a very basic test, I found this lens is a super wide lens comparing to most of 1.33x lens.  Basically, it’s front glass and rear glass space is near none.
