Fisheye with non-full frame sensor: Tunnel?

Fisheye with non-full frame sensor: Tunnel? posted by mercator February 28, 2010 05:47PM reply | quote

Hello,

For weeks I have been looking at the new fisheye lense. Now that it is for sale in Switzerland, I am about to buy one. There is just one question I have: How do pictures look like with a non-full frame sensor camera, such as a Canon 40D. Do I get a "tunnel view", i.e., with lots of black in the edges or does the image fill the whole sensor? Perhaps someone can post an image taken with a Canon 40D?

Thanks a lot,
Mercator

Hello Mercator
This photo is taken with a Fisheye Optic [F/4) and a Canon 40D - no chrop. As you can see, the edges gets black,I think you have to live with it, or do some chropping.
Best regards

...And after you crop off the corners, there is not much fisheye effect left. The result is just like from a bad regular wideangle.

If you want a fisheye effect, you should buy a lens that is designed for you sensor size (like Sigma 4.5 (for circular images) or 10 mm, or a Tokina 10-17 mm fisheye zoom).

(Note: A Nikon APS-C sensor is a little bit larger and thus a little bit better)

That kind of defeats the object of it being a lensbaby, which I assume is the point..?

Mercator, do you want a whole fish eye effect (i.e. a circle), or are you trying to avoid it..? The cropped sensor will have the effect of a longer focal length, so less of a fish eye effect, less likely to have a full circle isolated with black all around..
