Do you know the way how to use dual focus? maybe the lens has no problem.

Looks like in TTC subway.

Yes, IMO, if you have different 2X anamorphic lens and not plan to sell again. It is easy to combine them as different ratio anamorphic lenses you like. Like your Rectimascop 48/2x front lens with ISCO integrated rear lens, you will get a 1.3x or less ratio.

how about this: http://www.ebay.com/itm/332049422516

To me, smaller filter size and larger aperture should be better choice. So OM 50/1.2 is the one worthy to try, only with 49mm filter thread.

No anamorphic lens used, right?

http://ebay.com/itm/142179783601 not mine.

Basically, I have figured out some rules. Longer lens has less dioptre than shorter lens. I got help from a friend in optical shop, where has instrument can check the lens. These are rear lenses of different 2x anamorphic lenses: Sphere/Cyliner A. +6.00/-6.00 B. +5.00/-5.00 C. +4.75/-4.75 D. +3.50/-3.50 Front lens should be like this: E. 0/-13.75 F. 0/-10.50 Many front lens are too thick, the instrument was unable to check. Also some front lenses I did not take apart. For example, if B+F is original 2x lens, then A+F would get about 1.7X, C+F would get 2.2X, and D+F would get 2.7x.

In this way, just have strong breathy effect, not very good for video as focusing unit. Similar to what I modified as auto focus lens for photography, that is excellent. But nowadays, most digital lenses are made as internal focus lens, which cannot be used.

Now I can tell you the key difference of these two lens. The rear elements are basically the same size, very close. But the front's difference are huge, 16h is much thicker, twice in weight.

What I used is for photos. So use up 3:2 cmos. Yes for video, 16:9 mode would be less vignettes. So I believe ok for 85mm. We are taking the same lens, integrated lens, small one.

At infinity with small aperture, still have some darkness, not so perfect as 16h. It is perfect with 100mm on FF, except flare.

IMO, kowa 16h/8z/B&H's advantage is wider. Very good for 85mm on FF, no other ana lenses can do without vignettes.

I don't have time too. So just use 52 or 55mm to 50mm adapter ring.

I don't know anything about coreDNA. Just knew under $1k Ana lens, 16h/8z/B&H/Elmoscope II...they have the same optics, are the widest lens, but coating might differ.

No. need 16h or rebranded lens.

Agree. IMO, ELMOSCOPE-II has more value than KOWA B&H lens.

Hehe, too heavy to me. I remembered the front glass of Moller 63/2x is around 0.47kg. So I think the 46/2x or 48/2x lens are the best size for me. The front glass is around 0.3kg range. But the 32 lens is too small. BTW, who knows what this number mean? But I guess it maybe the rear glass size in mm, looks very close.

How much the front lens weight? If less than 350G, I am interested in it. I can tell you this Ana lens's front lens is easy to take apart. But rear lens is tricky, you need to make a special tool to unscrew it. Because it is in too deep.

Last two are at f/2. Maybe. But 16:9 for video should be a little bit better. Two more f/2 here, shown different focus point.

Tested this Zeiss lens with 100mm/f2 taking lens on FF camera. Is it OK?

Some one ask about these. So I just took some picture with 16H for comparison. Rear mount thread is the same as 16h lens----50mm. Size and weight comparison, see pictures. Roughly tested, with 85mm taking lens has obvious vignette on FF camera. I think it needs 100mm or above at least.

Zeiss's coating looks like more purple and Moller more yellow. No preference to me. They all have good flare. May be not very rare. Need to use keyword "anamorphot" to find it. I just bought it. http://www.ebay.com/itm/401180992655

This 46/2x lens is my favorite size for FF camera. Suitable to add 77mm filter thread for the biggest filters I owned. I think they are identical. But coating colors are different. Which brand was original? Zeiss Ikon? Möller?

Believe or not, schneider cinelux + isco ultra-star + EF 40mm = kind of unique combination
