A new tiny fast lens with swirly bokeh!

I think it will make a fabulous street lens (especially if there is a GXR with a built in EVF). Its size with its hood is about the same as the Computar-TV 25/1.3.

Though one sample of the Fujinon-TV 25/1.4 I have will be even smaller (albeit not that fast) and with better, smoother OOF rendition.

The smaller Fujinon-TV 25mm/f1.4 (HF25HA) is about 30mmx30mm, is designed for 2/3" video and vignettes heavily. The Fujinon-TV 25mm/f1.4 for 1" video (CF25B) is about 45mmx45mm and vignettes very slightly on m4/3 in 4:3 (without modification).

In my opinion, the Fujinon-TV CF25B is ideally proportioned to a small m4/3 camera like the GF1, and handles very well on a GH2. The focus and aperture rings are of appropriate size to locate and adjust blindly. With smaller lenses, if find these adjustments more difficult simply due to the small size and the close proximity of the iris or focus ring within the recessed c-mount adapter.

The CF25B is definitely a class above this MSOptical lens, if we may evaluate it from the images from this prototype. The Fujinon CF25B will yield terrifically sharp images with excellent color and contrast with smooth bokeh and very little to no swirl.

I don't really understand the point of this MSOptical lens... there are millions of dirt-cheap CCTV lenses that provide the same sensor coverage, image quality, swirl and bokeh characteristics.

ekoe, The one(s) I refer to aren't the ones you are talking about. One of these days I will snap pics of them. Rare as hen's teeth.;)

Very interesting, Vivek. I have handled several of MS Optical's conversions, and lens offerings (such as the Perar 35/3.5) but I found them to have rather fiddly ergonomics and are almost too small...this one in Pentax Q mount looks improved in that regard...
