How To Add An ND filter To The Impossibly Curved Rokinon 8mm F2.8 Fisheye Lens

We mentioned the Rokinon 8mm f2.8 several times on the blog as being a great lens for its price. One thing that is kinda hard to do with this lens is use filters. This is both because the curvature of the lens extends beyond the filter thread and also because of the shape of the petals of the built in lens hood.

This makes it practically impossible to place an ND filter on such lens. The folks at CheesyCam just shared a sweet hack using a Rosco ND gel and some blue tack. The trick is to place the gel at the back of the lens rather than in the front of the lens as we usually do. For ND CheesyCam uses the 3404 gel from the Rosco cinegel sample book, which cuts 3 stops off, and placed it using some blue tack.

Even zoomed in at 400% I was actually quite surprised that the gel almost did not introduce any softness.

P.S. You can use a similar hack with the Rokinon 8mm f2.8 to shoot infra red photos.

Shooting Infrared Using A Fuji X-Pro1 With A Rokinon 8mm F2.8 Fisheye Lens

I have devised a way of using the very popular Rokinon 8mm F2.8 fisheye lens that comes under several other branded names including; Samyang and Bower. The photo included is of no great interest. In fact it’s just a photo taken at the rear of a house. But, the significance of the actual image lies in the fact that it is an infrared photograph taken by using a 8mm fisheye lens on an unconverted Fujifilm X-Pro1.


Surely a filter cannot be fitted onto the front of the 8mm fisheye lens? So how did I do it, I hear you ask? The answer is after the jump, but lets just say that, this is going to be one of those try-it-at-your-own-risk kind of posts :)
