Omuni-focus Lens

Omni lens(3)-003About a month ago, I talked about Halina camera and its lens. —– A story how I made its lens to use on the Sony A7R camera and showed its sample photos.

Omni lens(2)While checking those homemade lenses, I found that the said Halina lens could, (with an additional diverging lens on front, as its focal length become longer) be used with a thicker Nikon body.  So, I further modified to add a diverging lens and mounted them on a 42M (Pentax screw) to Ai (Nikon) mount adapter. = Here I got Omuni-focus lens for Nikon DSLR. (And this work was somewhat related to the other lens)

I know, this situation is having a silly contradiction.  Why 47.5 MP Hi-Res camera need such low-Res images ? —– Omuni-focus mean, nowhere having a “Distinctive OUT of FOCUS (Bokhe) image” in the same time, no “Clearly Focused image” either.  = Just rotten images spread from top to bottom. ( More like a pinhole photo ! )

Now, my point must be clear, not necessary only decent sharp image could be a good photo.  (Though, I’m not implying my fuzzy image here IS a good photo.  😀

Omuni—– May be not a good photo still, I found that those fuzzy images appeal to our deeper psychology. —– I had distant memories in my subconscious, I might have seen this long long time ago —– may be even on my previous life ? ? ? )
