ownership:I own this lens
compared to:This was my first fisheye lens so can't really be compared to anything about from a Google image search! I suppose I was considering getting the Sony 16mm fisheye at the time?
price paid:750 GBP?
positive:Certainly unique, true 180deg FoV fisheye for aps-c sensor.
F2.8, suitable for low light conditions.
13.5cm min focus distance
Flare issues, probably can't be helped due to extreme FoV!
comment:A very strange but wonderful lens to play with.

It was my first fisheye purchase and not something I regret. A unique perspective is an understatement on this one. The effects you can get with warping buildings, bridges and people - plus capturing those who think they've escaped - is remarkable.

All in all, I'm happy with the purchase I made (a couple of years back now I think). However I only recently learned that the ring on the end of the lens can be removed! Oh well...everything's a learning curve right?

Ok lets see, what about negatives. Well the first time I used the lens, my toes kept appearing on the bottom of the images! It took quite a while for me to get used to the lens enough to avoid that happening.

I haven't tried the lens out at night yet although it handles low light conditions really well on my a580. Used on a bright day, flare is a problem when the sun is not obscured by cloud.

It seems a little on the heavy side for a lens of its size, but not that much to be a serious issue. The 10mm version seems to feel a bit lighter.
