Which fisheye lens is best on a full-frame camera?

Sigma 15mm or Tokina 10-17mm fisheye? – by Scott Gietler

• Most people think the Tokina 10-17mm fisheye won’t work on a full-frame camera. Not true! At15mm, the Tokina 10-17mm fisheye will produce exactly the same image as the Sigma 15mm fisheye on a full-frame camera. 180 degree angle of view! No need to go into “DX” mode with either lens.
• The Sigma 15mm is a 2.8 lens, versus Tokina 10-17mm fisheye is F4.2 at 15mm
• Many people moving up to full-frame already own the Tokina 10-17mm fisheye
• Let’s see the test results with a Nikon D800, Sea & Sea housing. Contact us to find out details on dome ports / extensions used, and which ones are best

 

Both lenses give exceptional detail at at 100% crop. This is pretty impressive, given the fact that the Nikon D800 is a 36 megapixel camera!

I took center shots and corner shots at F2.8, F4, F8, F11, and F14.

I’ll be posting these photos later in the day on February 13th, 2013 – so stay tuned!

Both the Sigma 15mm and Tokina 10-17mm fisheye lens give great results at F11 in the corners. The Sigma 15mm fisheye looks slightly better, but not a huge difference.

Tests at different apertures

Center Sharpness

• Sigma 15mm – f8 – F14 was very good, F2.8 – F5.6 was good
• Tokina 10-17mm – very good at all apertures, better than the Sigma at F4

Corner Sharpness

• Sigma 15mm – poor at F2.8 – F5.6, OK at F8, good at F11 – F14
• Tokina 10-17mm – poor at F4, F5.6, OK at F8, F11, good at F14

I will post some 100% crop photos soon. – Scott Gietler
