I've seen several posts here about the need for a super-wide angle lens for the 645Z....this is a very rare drool-worthy 24mm fish-eye Zeiss made for the Hasselblad V series...with price-tag to match!....have to assume image quality is very good?....no FOV data that I can find , but someone will now I'm sure?

After defishing to make a rectilinear super wide angle image,
it may not do much better than the recent prime or current zoom.

Sucks considering that the 23mm for the Fuji GFX is an outstanding optic and our system has been around for years but has nothing.

FoV should be 180° on the diameter, I guess...

Interesting that the ad shows it in use on a 645D....

Cool piece, but yikes...price!!

Buy my D-FA 25mm (on eBay.co.uk now...) use it on a 645N film camera and you get a lens that's equivalent to a 14.5mm lens!! Woof!

No lens in the world is worth that sort of money... I doubt it would give any better results than the 28-45 which has spectacular quality.

True, though once you de-fish a 24mm, you will lose some of the angle of view. It could be that the 25mm gives you more than a defished 24mm. 28mm I am not so sure about. But assuming you don't want the fisheye effect, the difference will be less than one might expect.

why would anyone pay that much $$ for a fisheye if they wanted to de-fish the images? There goes the IQ as well as the FL benefit. I'm with you on that.

Why would anyone pay that much for a fisheye period? ;-)

And a fisheye, by Hasselblad, priced extravagantly (as with so much in HK!!) with haze/fungal infestation [pic 9]

. Go figure...

finding myself with a -35mm and a a-45mm lenses, I went the cheap route. I found a 0.5x screw n lens on the 45mm lens I get a very wide angle. with the 35mm I get a circular fish eye effect. the images are nor great, but they'll do.
