Description:

A fast (F1.2) wide angle lens on 24x36mm full-frame (field of view 54 degrees horizontally) and a normal lens on APS-C (field of view 38 degrees horizontally).

The click stops of the aperture ring can be disabled with a switch thus making the lens suitable for shooting video.

Kerlee 35/1.2 is an very impressive lens.

Build quality is among the best in modern lenses I have experienced, although it is large and heavy (which something I am not very fond of). Even the lens hood in made of metal. Focus ring is very smooth and has enough throw for precise focusing. The aperture ring has nice feel to it and has a switch for clicks or clickless operation. With 14 rounded aperture blades the aperture stays circular on all apertures.
This lens do not have any aperture lever, so the aperture is not held wide open, so it operates more like an adapted m42 lens.

The first copy I got had a defect aperture mechanism, so it could not be stopped down, but the replacement I got worked perfectly.


I have not used this lens very much yet, so this is more of a preview. I will update this review when having more experience with it, and add images when I have some that can show what this lens is capable of.

Image quality is very good, but not perfect. Wide open it is soft but still usable, and stopped down to f/1.4 - f/2.0 it is starting to become very sharp. Stopped down to f/4-5.6 it is probably the sharpest lens I have (center sharpness).
Edge sharpness is not the best and it never get really good. Stopped down to f/11 it seems to be useable for landscapes. But this lens seems to be designed more like a portrait lens, than a lens optimised for best possible sharpness over the whole frame.
The best IQ property of this lens is perhaps background blur or "Bokeh" which is very soft and pleasing. So I believe I will use this lens mostly with large apertures, and it is an f/1.2 lens after all.

I got this lens mostly for use with FF mirrorless, but also to be able to use it on my K3 II. Although I doubt it will be easy to focus manually wide open on an APS-C DSLR. On my K-mount cameras the lens was very "stiff" to mount and required more force than I like. On the Adapter used on Sony A7 it was no such problem.
Manual focus wide open is difficult, but with focus peaking and zooming in the EVF it was fairly easy. But it is easy to miss focus if not holding the camera steady enough as a very small shift is enough to miss focus.

I was able to find this lens new at a bargain price at a Swedish online retailer, so I could not resist buying it. At approx $200 it is hard to find a better 35 mm lens.
