What are the cheapest fisheye adapters for a Nikon D3100?
The lens that I use for my Nikon D3100 are 18-55mm, so I think that if I were to use a fisheye adapter with it, the adapter would have to be 52mm?
I'm not looking for quality; I just want to have fun with the fisheye effect.
What are some fisheye adapters under $50 (Canadian)?
I have found one before on Ebay and Amazon, which was right around $50, and yes your looking for a 52mm.
The all-glass high resolution optics of the Precision Design.25x Super Fish Eye is manufactured in Japan and have been engineered to do one thing and do it well; reduce the focal length of a lens by.25X to provide an amazing fish eye view. Depending on the camera model and lens it's mounted on, the image can cover the entire frame edge to edge or provide a circular image fully contained within the frame. Mounted to a zoom lens, the Precision Design.25X can often offer ultra wide angle, diagonal fisheye (full frame) and circular fisheye images. Close focusing is almost to the front of the optic and there's huge depth of field.
The.25X can be a great tool for real estate agents or for just having fun! If you plan on doing panoramic or full room shots, just stand your tripod in a corner facing the center of a room. It can capture almost EVERYTHING, floor to ceiling, wall to wall, except what is directly behind the camera. Just import the resulting image into a panoramic editor or "stitching program" (your digital camera probably came with one), convert it to a QuickTime VR file, and have a virtual view of the room.
The Precision Design.25X is the affordable fisheye optic for useful, unusual and fun pictures you otherwise wouldn't be able to obtain.
WILL WORK WITH ANY LENS WITH A FILTER SIZE OF 52mm, 55mm, 58mm & 62mm (lens is 58mm, 3 adapter rings included) which includes most Nikon, Canon, Olympus, Minolta Maxxum / Sony Alpha, Pentax, Tamron, Sigma, Tokina and other major brand lenses.
This 0.25x Super Fisheye Lens can mount to almost any digital or film SLR lens made with optional adapter rings.
