Of course having such a fast lens should not be wasted on flat images of landscapes, so be creative with this one.īokeh can be swirly or smooth depending on the circumstances as you can see in the next image. Images do have a specific look to them that you won’t find with native lenses. More importantly colors and contrast feel punchy when used in bright light and restrained in low light. Resolution is good enough for my taste at F1.3 in particular towards the center and getting very good towards F8. Getting swirly at F1.3 Unique interplay of light and shadow F1.3 Distant focus is somewhat possible by closing the aperture to >F8 Take a closer look at the following sample images (unedited jpgs). So what about resolution, contrast, colors and ergonomics? Well, overall performance is surprisingly interesting from a creative standpoint. I am not sure how to convert the 25mm focal length exactly, but this lens felt like a fast 50mm to me.Ĭheck out my Flickr set with this lens for full images. We are using an Olympus E-PL5 (M4/3) with a 16 MP sensor. Having only three aperture blades seems pretty unique to me, but I could not see any distinctive triangular bokeh shapes in my images. Is is manual focus and manual aperture with two metal rings for control. The lens is tiny even by M4/3 standards with an all-metal body that feels compact and sturdy. Flat adapters to M4/3 or Fuji-X can be found for few coins from China. However, closing the aperture and thus increasing the depth of field gave me quite sharp looking images for distant objects. That means you are not getting perfect infinity focus unless the adapter is intruding into the M4/3 camera and I could not find such an adapter. The flange distance for C-Mount is 17.53mm and thus slightly shorter than M4/3 at 19.25mm or Fuji-X at 17.7mm. Tiny Japanese-made, all-metal manual lens with 3 aperture blades This particular Japanese Computar lens is made for 1″ digital sensors and is capable of covering most of the larger 4/3″ sensor with small vignetting in some circumstances. C-mount was made for smaller 16mm film cameras back in the days and is used today for 2/3″ or 1″ sensors.
