Hi everyone, I just bought the Bower 14mm f/2.8 mainly to shoot astrophotos and startrails.
I was using my Sigma 10-20mm till now but i needed a faster lens.
I like the lens, it feels great, but looking at the 100% crop of my first test images with it, I have this weird 'halo' around the stars.
Please look at the unretouched crop below, the 3 main stars of Orion's belt clearly shows what I'm talking about..
I shot wide open at f/2.8, 20sec at ISO800 on the K3. I have another shot at f/3.2 and it's a little less obvious but still there.
I obviously don't want this lens if I can't shoot wide open with it.
I have been shooting stars for a long time so I know this is not normal, should I just send it back and ask for another one ? could it be a bad sample ? I bought from B&H so I know it won't be an issue.
Thanks for any feedback!
