EXAKTA (Cosina) 24mm f/2.8 Macro P-KA lens
Looking for a 24mm KA-lens I was lucky to acquire one of these on *bay for about 55 EUR.
This lens seems to be available from different brands and was build by Cosina AFAIK.
Although it only has five aperture blades, I like the Bokeh. It's sharp wide open and can focus down to about 15cm. See three examples taken with my K-5 in the reply.
The only thing which isn't quite right:
I have to compensate exposure for smaller apertures by -0.5 to -1.5 EV.
Lenses with KA mount should have a linear aperture steering (in contrary to older lenses like M or P). So here's my question:
Is there a model of this lens which has linear aperture steering (as required for A lenses)?
we don't see that we don't see (eye's blind spot)
