I stand corrected. It is not circular fisheye as it follows from your
photos, Dario. It is apparently diagonal one...
This is way cool!

Hi Larry, my advice is 'go for the 8/3.5'. I own and enjoy it beyond my
most optimistic forecast when buying.
Just see here a few pics, taken on Friday at the PDML meeting in Venice:

Focusing is not so easy, because focus and out-of-focus is not so
obvious in viewfinder, and the focus indication can be fooled by the
lens properties (a minimal shift in optical groups causes a lot of focus
shift). For that same reason, a perfect tuning of focusing ring at
manufacturing is not so easy for such lenses. However, I believe the
spirit of such lens is having more focus planes in focus at a time, so I
tend to focus it by looking at the focus scale and set F8 for aperture
(the very shirt focal length allows for longer shutter speeds without
worrying so much about motion blur). That works pretty well. All pics
above have been shot that way.

Subject: About those samyang lenses ....
We just cashed in a bunch of loose coinage and have over $200 in Amazon
credits. This is nearly enough for either the Samyang/Rokinon 85/1.4 or
the 8mm/3.5 and I'm quite tempted to make an impulse purchase.
I've heard a lot of good about the 85/1.4, but since I have the 77/1.8
I'm quite tempted by the 8/3.5. Especially since my current widest lens
is my 16-50. Anybody have experience with the 8? Or ideally both
lenses? Suggestions? Advice? Warnings?
How hard is it to focus the 8mm? Or with the short focal length, is it
harder to get the shot out of focus?
