  • 12mm Noktor question.

    It seems like you can buy either the standard 12mm Noktor or a version with '58/77 ring'


    So what does that mean having a 58/77 ring. The version is a little more expensive so am wondering if I need it or not?

    The "58/77 ring" is an adapter that changes the filter thread size from 58mm to 77mm. I'm guessing you pay more for that adapter ring.

    "Filter Mount: internal thread for SLR Magic 58/77 RING (optional) lens hood for 77mm filter; filter mount does not rotate."

      What's better about having a 77mm filter ring over a 58mm one?

        77 ring is much more universal. Most Canon L will take 77, as will the Tokina 11-16, and many other popular lenses. It is in my opinion, the most standard screw in filter size there is. It's also large enough that anything smaller, you can just get a step up ring. But if you have 58mm filters, then they will only work on your smaller lenses.

          The 58/77 ring is a solid addition to the lens. Generally, adapters are cheap feeling and bend easily, this one at least feels like it's sturdy, and matches the lens.

          I've got the 12/1.6 With the lens gear and the 58-77 ring. Recommended.

            All my ND filters are designed for 82mm thread - if I bought the SLR Magic 12mm T1.6 and used a 58 to 82mm step-up-ring (which I own), will I have vignetting?

              It shouldn't vignette at all above 72mm. However, stacking TOO many filters might get you there.

                Cool, thanks for the reply!

                How many would you say is "too many" - I don't plan on using more than two ND's at a time.

                  Beyond three's too many, IMO. Three's actually pushing it.

                  Buy heavy ND, that way you only stack one ND and one other filter for what you need, likely either a Polarizer or an effects (black, soft, haze, grad, etc).

                    Thanks for the advice, Kholi, much appreciated! I plan on using a 1.2 (or 1.8) ND/IR filter (something like this: http://www.bhphotovideo.com/c/produc...l_Density.html), then stacking either my 0.6, 0.9 or 1.2 if I need more ND.

                      Buy a 9 IR, 1.2 IR, 1.5 IR, 1.8 IR, 2.1 IR and you should never need to stack two filters just for ND.

                      1.2 ~ 1.8 will take care of any wide open shooting you want to do, 2.1 is just good measure if you're trying to 0.95 wide open lol

                        I don't know if I could afford a kit like that right now. Perhaps I should just get a 2.1 ND+IR for now (http://www.bhphotovideo.com/c/produc...l_Density.html) - considering that the camera will be kept at ISO800 and lens at F2.8 - F4 (for day shots).

                          Shooting wide open in bright daylight is a completely stylistic aprroach and there is nothing wrong with it. However I would like to point out that Roger Deakins believes in closing down for open daylight. He says that it mimics the eye, and that our eyes naturally close down in sunlight. He goes between f8 and f16 if i remember correctly. Now with the smaller sensor you'll need to adjust accordingly to get the same DoF, but he doens't go as shallow as you'd think. Just some food for thought and maybe save you a little green/options.

                            Wow, that's really interesting! I'm not too big on shallow depth of field to be honest. I usually shoot my day shots between F4 - F5.6. I really like Deakins' ideology behind day shots - I'd love to do a few tests and see how F8 footage looks.

                              Is the ring adapter fixed to the lens or removable?
