Hello fellow Pentaxians
I recently got a new Sigma 30mm 1.4 from B&H and didn't really use it much till now. Now there are some issues I've noticed that are causing me to consider returning it. The attached image shows the aperture blades are not uniform. There seems to be one blade that isn't in place. This causes some of the bokeh at certain apertures to be lopsided and misshapen.
The other thing is that strange circular pattern in the bokeh. I tried cleaning the inner surface of the lens, but it's still there. Any other owners of this lens have these issues? Any idea if it's a problem with this lens or just my copy? Would you return it over this? I appreciate any thoughts Forum members have. Thanks in advance.
