Sigma 8mm f4 manual focus circ. fisheye vs. A Peleng 8A f3.5 Wishfull thinking was [ ... vs. Zenitar-K 8mm f2.8]

[Peter J. Alling]

That was wish full thinking, I meant to reference Peleng lens.  Just 
replace Zenitar references with Peleng and all will be well.

As some may have noticed I rather like using fisheye lenses.  In 
anticipation of Purchasing a *ist-D, (or *ist-Dn it's successor
or whatever they call it, based on how long it's taking me to raise the 
money), I'm looking into reasonably priced Circular fisheye
lenses on the assumption that these will be almost full frame  (22.x� 
image circle) on an APS sized sensor.  Does anyone have any
direct knowledge of these two lenses or know of any on line reviews.  
About the only things I've been able to discern is that the
Sigma has an A equivalent mount while the Zenitar is a K mount.    I'd 
appreciate the information.
