Sorry for reviving the old thread. Any luck with the comparisons? I have been researching this too!

Hey guys,

I'm looking for a hypergonar 16 in good condition - any of the 5 models, apart from the 6th one with the concentric rings.

Let me know if you have anything... thanks!

Hey guys,

I salvaged an old anamorphic projector lens, and there's an issue with the rear element (specifically, its outer surface).

It's foggy (almost like ground glass) - but it also has some tiny splotches which are clear. Based on the shape of the splotches, I figured it was somehow fungus related, so I gave the lens element a short vinegar bath, and then also some stronger fungicide, but it didn't change anything. I also swabbed the surface with acetone (I figured I can at least take off some of the coating) but again, nothing happened. This thing seems to be bulletproof... The other side of the element, as well as its cementing, seem to be fine.

I attached some pictures. Any ideas how to restore this? I am happy to strip away the coating or any other drastic measures, as at the moment this element is unusable.

CLEAR SIDE:

FOGGY SIDE:

How does it perform when the taking lens is wide open? Is it soft? CA?

Sean from http://followfocusgears.com/ does custom gears - he made a gear for my Kowa B&H 2X anamorphic. recommended!

part of the issue is that rear anamorphics (these are already a thing - often used on zooms) don't create the traditional anamorphic artifacts/aesthetic in the image...

how bad is the separation? And is the chip in view or to the side?

PS - messaged you

Anyone looking to sell a 2X S8 iscomorphot / animex lens? Let me know

Also interested in any other 8mm 2X anamorphics!

A short sci-fi film I directed. Shot on BMCC + a lot of CG/vfx. Filmed in London, China, and Hong Kong.

any feedback welcome :-)

On a side note - how are you finding the rangefinder with the Kowa?

yeah. the problem is not the desqueeze itself - it's the lens distortion of the anamorphic. It's quite a pronounced sphere at the edges, so they become 'compressed' more, if that makes sense? Depends on what software you are using, but I've had good results (not perfect but close) in Nuke - using a checkerboard grid that I filmed as a calibration tool, and then re-straightening it...

PS - 16s has a 39mm back thread, not 52mm

Hey guys.

I recently salvaged and cleaned an old Sankor 16c - I've taken the old gunk off the helicoid and now need to replace it with some fresh grease. Any suggestions for which type of grease would work well? I'm based in the UK (London) so anything locally available would be preferred, but not necessarily...

DOF is amazing. Are you sure the blown red channel is just your grading - and not an exaggeration of the BMPCC's infrared problem in some way?

Looks great, but the 86/75mm threads are problematic - that's not even standard filter ring sizes. I couldn't find any step-up rings to 75mm.

No the zeiss didn't - it covered the full 1:3.55 anamorphic frame cleanly. The widest taking lens I can go with that combo is 45mm, in my experience - but the range of 45mm lenses is much worse.

Thanks! I've been temped by the Summicron and you may have convinced me Is there a significant difference between the versions? (2 cam, 3 cam, leica r only, etc) I've heard that the later ones (with 55mm fronts) don't vignette on S35... I'm using it on a BMCC with speedbooster, which turns out to be approx. S35.

Until recently I've been shooting on a Contax Zeiss Planar 50mm f/1.7 (MMJ version) coupled to my Kowa B&H. I've recently finished a short that was shot on this combo, and I absolutely love the image.

The only problem I have is with the build quality of my Zeiss - there is a bit of play/wobble in the front filter ring, and with the anamorphic front it's enough to skew the image slightly. In practice this causes a lot of faffing around, to make sure everything is aligned each time, so I'm looking to upgrade to something a bit more sturdy. The only requirements apart from the build quality are manual iris/focus, EF-adaptability and a small front element size for the anamorphic (no 77mm monsters). I'm considering the following options:

- Another Contax zeiss 50/1.7. Like I said I love the image, perhaps I was unlucky with the build quality.

- Zeiss ZF2 50/1.4. I have a friend who shoots on this combo (with Kowa B&H) and loves it. I've heard it's a bit soft wide open though...

- Leica Summicron 50/2.

- Voigtlander Nokton 58/1.4. I had the Voigt 28/2.8 and loved it. Would ideally prefer a 50mm not 58 though.

Any opinions? or recommendations? Not considering the helios or jena primes as I have a few of them but want something a bit higher level as this is my main lens.

Interesting, Brian. Does the size of the front optical element (of the taking lens) affect the sharpness as well?

Andrew - how was the FM's performance in comparison, from your experience? (I know there was some shitstorms with the seller, it's quite faffy and cumbersome, etc etc - but I mean purely in terms of unbiased optical image quality...) Was it soft wide open as well?

Is the FM lens sharp wide open? How does it compare to Zak's test shots of the RF and rectilux?

Thanks for the test! It's a shame that it degrades the image so much wide open...

Cool! What's the taking lens? How fast can you go before it becomes soft?

Thanks Zak! In your experience, is the rectilux sharper than the rangefinder?

Look up Sankor/Singer 16F - this is just a rebrand of the same lens

Hey guys - I know there's a few testers here ;-) Wondering if anyone had made any comparisons between any of the 3 variable diopter focusing-things, in terms of image quality?

I was looking forward to the SLR magic rangefinder, mainly because of its form factor - but was disappointed to read in Andrew's review that it's soft wide open. I'm not necessarily one for pixel-peeping, but I do like to shoot wide open on my Kowa B&H + Zeiss 50mm 1.7 combo...
