    vignetting

    hey guys. I have an opteka fisheye 6.5mm on my canon 650D and I want to find a way to vignetting my lens. https://vimeo.com/119334640 something like this in 2:20. There is any hood which I can use or some DIY ideas ? Thanks

      "Hard" vignetting like that is something people tolerate in order to get an ultra-wide fisheye on a 16:9 camera- mostly to gain more vertical field-of-view, similar to what you'd see on a 4:3 camera. It's a compromise, just one that happens to be acceptable nowadays, as it enables the ultra-close, mega-"freak da point three sonnnn" style of filming that's en vogue right now. Which itself is a response to the ~five previous years of rampant poor/lazy fisheye work so commonly seen with DSLR's- usually either A. too far away, too high (camera held in eyeline between skater and filmer), panning completely with the skater so they are always in the center of frame... or B. close, but with heads or even upper bodies chopped off.

      The setups giving the hard vignetting you're after are usually video cameras (HVX200, HPX170, etc) with an older Century fisheye adapter intended for a smaller SD camera's lens, modified to fit the HD cam's larger lens. These adapters were used for the first ~15 years of blade (and skateboard) videos, so their particular look (super "bubbly", with an increase in distortion at the edges, often with some vignetting) in part defines what many consider "real" or "authentic" skate videos. The "manybrand" fisheye (like your Opteka)- nearly ubiquitous in blade DSLR filming- however, has a unique distortion that isn't super "bubbly" or "fishy"- it's somewhat similar to rectilinear wideangles (which are "stretchy", not "bubbly"), and is also pretty consistent from edge-to-edge. And obviously it doesn't have any vignetting, as it is a photo lens and vignetting is usually considered a big no-no in photography.

      My point in explaining all this is that adding an artificial vignette to your DSLR/manybrand setup isn't going to give you the look you're after, because the look you're after is more than just the vignette itself. You'd just be taking the downsides of two compromises and throwing away the benefits. It's the same as someone riding what I call "retard rocker", which is smaller, worn-down normal wheels being used as antirockers (say 52's inside, 58's outside). You get none of the grinding benefits of anti, none of the turning/landing/skating benefits of flat, but you get the downsides of both.

      I would advise researching the Peleng 8mm or Sigma 8mm fisheyes for your Canon. Both are wider than a manybrand and will give you some vignetting (not as much as your example though). They do have downsides, though- the Peleng flares like crazy, and the Sigma is expensive. Or you can of course look into switching to a video-camera setup. Used HVX200's aren't expensive, and you can probably find a used MKII Century for cheap.

        Understood. Thanks al dolega for this. I should have gotten a peleng lens. I didn't know it! Dont like a lot my opteka 6.5mm.

          No problem man. Another option would be a Panasonic GH2, with a cheap Speedbooster clone, and the Peleng. This will give you quite a bit of vignetting, a bit more than the .gif in your signature, and an ultra-wide field of view.

              If you're going to revive a dead thread, at least read it first.

                With regards to Fisheyes, the Samyang 7.5mm fisheye for M43 cameras is pretty wide, but it's not very bubbly. It also doesn't vignette.



                I sold mine even though it was pretty nice for non-skating fisheye use. You can get wider/bubblier (and vignetting!) using a £5 fisheye lens on an iPhone which might actually have more of the style you are looking for. I actually prefer the shitty fisheye adapter for skating to the 7.5mm Samyang, but that might just be me.

                  Thanks for reminding me of the ones for phones, Olloclips for my iPhone 4S are like $10 on eBay, new in-box.

                    Mmmm I would have to slightly disagree about the 7.5mm's width. It's fine for photos but for video it's not all that wide. This is because m4/3 uses a 4:3 aspect ratio sensor, so when you crop to 16:9 for video you are losing quite a bit more than most other cams, which use a 3:2 sensor. The GH1/2 have multi-aspect-ratio sensors however, which gives a little less crop for video. Still not all that wide really, still completely usable though, and the 7.5mm is pretty sharp and its tiny size and weight are very nice bonuses. The less-bubbliness is due to the Samyang's/the manybrands' slightly-closer-to-rectilinear projection, as I explained above... it's a little closer to an ultrawide-angle lens than a conventional fisheye.

                      Fair point. For photos though it's still not that bubbly like you mentioned.




                      It's a cool lens though. Definitely, for the money, a high quality bit of glass. For skating though, I just don't think it works that well for filming for the reasons you mention. I think fisheyes on full-frame cameras tend to be bubblier though. On my film Canon SLRs, I thought the Sigma and Zenitar were wider/bubblier/more immersive.

                        face palm at people thinking that vignetting is a metal circle you put around a lens rather than an effect/flaw/artistic composition that is created by the lack of light on the edges of the glass (not a piece of lens hood literally obstructing the view).

                        i heard a kid say in all sincerity to an edit "whoa dude, nice vig". The video was actually impressive, but the dumb fuck kid was too retarded to understand why and just assumed he liked it because of a "vig".

                          Soft vignetting is what you described, but hard vignetting is literally because of the glass not covering the full frame of view so I can understand why people get confused about it.. I remember when people filmed on the XM1 (Navran?) and could see the small flange of the fisheye lens hood in the top left and bottom right of the frame. Most fisheyes don't even attempt to have a lens hood/flanges though so it rarely happens.

                          Funny how it's so back in fashion. When you get hard vignetting and the lens isn't even that wide it's awful to watch.

                            Maybe he was talking about a different vig?
