I am toying with the idea of picking up either the Samyang/Rokinon 14mm f/2.8 IF ED UMC or the 8mm f/3.5 Aspherical Fisheye lens.

These lenses have a built-in petal-shape hood and a "bulb-like" front element. I came across a few reviews about the 14mm f2.8 lens but all of which mentioned the "unusuall" front element and the if so special lens cap that should always be on the lens when not in use. At least one review says it is not possible to mount front filters on these lenses. Surely, there is a way...

In situations where I would be normally using these lenses I would want to be able to use ND filters. Is there any way to filters to these type of lenses and if so how and what type?


By default, you are unable to place filters in front of those ultra-wide angle or fisheye lenses.

There are however, 3rd party accessories designed to tackle just this issue:


You really can't use filters with these due to the wide angle of view. You could try to rig up something along the lines of a Cokin style filter, but it would have to be a very large filter to avoid vignetting.

Some lenses, like 400mm and 600mm Nikon teles, have a "drop-in" filter which you slot into a gap in the middle of the lens. Not sure if any fisheye lenses are designed this way

    I have a Zenitar 16mm f/2.8 fish-eye with rear thread for filters; normally, there's a clear one in place to retain correct focusing distance. – Imre Jan 30 '12 at 6:28

    The fisheye has an angle of view of 180 degrees. – MikeW Jan 30 '12 at 9:07

I have the LucrOit system since a week and I'm using it on a Sigma 8-16 with a Nikon D300 and it doesn´t vignette at all, neither vignette on my friend's Samyang 14 on a Canon 5D MkII. We both are very happy with that system, also my father has bought it for his Nikon 14-24 and he's like a boy because he can use filters on his 14-24.

BTW I strongly recomend the ND Prostop filter from Hitech, just awesome, the most neutral filter I've ever seen.

Wish you great shots.

  • Thanks! Good to know. I will be purchasing a Canon FF once the 6D hands-on reviews are out and I am seriously considering the 14mm Samyang. I do a lot of shooting with filters so I might as well consider a decent system such as LucrOit. – Jakub Sisak GeoGraphics Nov 30 '12 at 19:10

I've been using Lucroit system with Nikkor 14-24 since few months ago and it's really good. The HiTech ND Pro Stop (10 stops) is amazing. You can check these links:



Hope it helps you.

  • The photos are amazing and the lens rocks too! Out of my league for now. I will be getting a full frame and when I end up getting the 14mm Samyyang I will buy this kit. – Jakub Sisak GeoGraphics Jan 30 '13 at 13:55

A very simple and cheap hack consists in cutting and placing the gel filter behind the lens, that is between the lens and the camera's body.

You can see a tutorial here:


It can be useful to avoid overexposure as seen in the video, or if you are working with an infrared-converted camera, and need to use an orange or red filter, for example...


Or you could hacksaw some ND filters (the plastic ones) as I for one can't find gel swatches in the UK. I've hacksawed an ND8 filter and it fits perfectly behind the lens. Just add a little blu tack to keep in place...now to do with other filters


You could buy the lenses in EOS mount and then buy an EOS R camera and use the EF to R adapter with a built in rear filter holder.
