  1. depends on how you measure the length. looks you measure it at the longest. if measure in shortest, kowa's length<diameter. But Isco Ultra Star is internal focus lens, never change in length.
  2. mine is not orange flare one. ebay pn: 323677406425, not sure.
  3. I made my own lens. ๐Ÿ˜‚
  4. I use mspaint and working too.๐Ÿ˜€
  5. I think free HandBrake can do it.
  6. This lens wide/angle is between 16H and 16D. On FF, 100mm taking lens is safe, no vignetting at infinity. 85mm lens can use in closer focusing.
  7. where you see 2.1 and 2.4? taking lens aperture?
  8. IMO, if you can use it with standard lens (50~58mm) on FF, you need to thank god. ๐Ÿ˜‡
  9. I sold mine. Its IQ is much better than many other 1.5x vintage ana lens. But I can tell you, it only works on PENTAX Q or smaller cmose/ccd.
  10. try to focus(both lenses) at infinity with F11 or smaller. if still not clear, then it is misaligned issue of the ana lens.
  11. Your lens barrel has been cut out the distance marking part, obviously. Mine's price? I think it worth around $200 nowadays. Its front lens was too bad when I bought, not usable. So I took out rear lens for use with other front lens.
  12. Hey, your lens has been modified. I believe it has reached to one end. Please refer my picture. BTW, if you need, I can sell mine to you, mechanic parts only, no glasses. ๐Ÿ˜
  13. my mod is just cut it. if you need to take out front lens, besides loosing screws, you need to soften epoxy points by heat gun.
  14. Believe or not, Moondog lens for iphone is the least distortion lens and widest too I have ever used.
  15. I think because it is projector's lens. Widescreen actually is curved. So the lens may design this way could focus on edge.
  16. can you tell us what are the modifications?
  17. no right or wrong absolutely, depends on shooting mode is 4:3 or 16:9. in digital world, you can crop the video to any ratio you like.

    Kowa advice

    Maybe not many people know, 16D has its twin named 35J. 16D usually means Sankor's 16D. And don't confuse with Kowa 16D, which is smaller lens.

    Kowa advice

    Imo, this is the second worst anamorphic lens than Russianโ€™s. That is why itโ€™s so cheap.
  20. similar to Proskar, Sun. Eiki(16F, same as Senkor) is more recent lens, sharper.
  21. IMO, they have the same sharpness for all these size lens. The difference is the view angle. ISCO can use 100mm without vignetting at infinity on FF camera. 16-D needs 135mm.
  22. I don't think so. Definitely a 2x lens for me to use. Here are 3:1 pictures from 3:2 sensor camera.
  23. IMO, this lens is sharp enough and true 2x at infinity. But it is the least flare lens.
