Hello Racer,
I wonder if the Sigma is not a little brighter and sharper on your samples ... Is it your feeling too ?
On my side I received the tiny SMC Pentax-m 28mm F3.5. It's a very nice lens, not much used, almost mint and optically very good.
Is it as sharp as my Sigma super wide II 24mm ? sometimes yes, sometimes better ?, can't say. But so different in fact. It's not a fast lens, colors are deep, and rendering is like argentics (even mounted on K70). I find the same kind of colours on my 50mm F4 Takumar, same "3d" effect.
I can't always reach the red dot at infinity focus even though horizon is perfect when closing the aperture ring between F8 to F11, seems it's perfectly adjusted (for argentic times).
Every manual control is smooth with a feeling of solidity.
The lack of automatic aperture is disapointing at first on this lens, use of the green button (for exposure) is needed and full manual (focus + mode) too. It's like "Back to the Future", another type of photography, with more time needed and economy of the fire button. But real art, and very relaxing.
Having a good exposure becomes a challenge.
28mm (42mm equiv) is a very nice angle of view.
(it stays on the camera from now)
