That is great, and a good price too.

I'd be tempted if i didn't already have two fish-eyes.

The store I bought it from mislabeled the Fujinon 1.4mm F1.8 as a CS, Fujinon 1.4mm f/1.8 Fisheye lens CS Mount DF1.4HB-L1 - Ideal for All Sky Camera but to my delight itís actually a C mount lens! Simply mounted it with the same inexpensive one piece C to PQ adaptor as I already used for my Funjinon 2.7mm F1.8. I can even employ the same rubber O-ring as a variable thickness shim for re-focusing from zero to infinity! Outwardly the dimensions match the 2.7mm F1.8. Without the labels, you could not tell them apart. The sturdy plastic lens cap came as a bonus that fits my 2.7mm F1.8 lens too! I wish I had spare. The accompanying simple rear cap is nothing to write home about but appreciated still.

Confirmed my suspicions that itís a full circular fisheye image on a Q-S1 (what I wanted), and a gives a cropped-circle image when pairing with my original Q. How much crop off the top and or bottom varies depending on the stabilization compensation and your C to PQ adaptorís alignment.

Resolution I consider is still on par with the 5 MP 2.7mm F1.8. It also exhibits similar purple fringes in very high contrast situations but I am able to rein them in with a few sweeps of a finger via Snapseed, the sample below was cleaned up this way.

Field of view is certainly more than the 180,
I am not sure how to measure how wide exactly but I guess 190 or more.

If you want a fast fisheye that fills the frame on either the smaller or larger sensor Qís without a black circle, the 2.7mm F1.8 is great.
If you are after the extreme look of a full circle super fisheye for the Q7 or Q-S1, this is a neat and perhaps at this moment, even unique proposition. £65 inclusive of postage within the UK, is not outrageous IMO.

What do you think?
Cool find. Image quality is nice. Tempting, but the few times I need circular images, will just use the other Fuji on the Olympus m4/3.

Thanks for sharing,
