Hi Frits: I used one of these some years ago for a day. It was a bit of a novelty which wore off its appeal pretty quickly.
With a M50mm f:1.7 it gave a full frame image with enough distortion to call it a fisheye effect. With my M28 f:2.8 it gave a circular image within the frame. Optically it had poor sharpness and very low contrast (muddy tonality). It was nearly useless with the 28 mm lens. Needless to say I never had the desire to use it again. I imagine all of these add-ons would give you similar quality. Not recommended. Cheers, - Andrew. -----Original Message----- From: Frits W�thrich [mailto:[EMAIL PROTECTED] Sent: March 20, 2003 2:43 PM To: [EMAIL PROTECTED] Subject: Sunagor lens I am holding a Sunagor Super Wide Semi Fish-Eye 0.42x made in Japan lens in my hand. It has no focus control or aperture. On the back it has 54mm thread, and a step down ring to 52mm. If I understand this correct, you can mount it on a lens like a filter, and it will give you a wide angle lens. Doe anyone know how good this is? What would the value be? The lens is in very good condition. -- Frits W�thrich Pentaxianado
