Purchasing Sigma 35 f/1.4: how to know it is a good copy?

it would be easier if you could precise where was the focus point on each picture

FF/BF issues occur when you focus on a specific point and get blur / sharp image instead of what you aim to shoot

Yes you're right! lol sorry new to this forum...

1st pic was focused on wine bottle with blue cap
2nd pic was focused on banana tree behind blue cap wine bottle

Thanks. Please ck for me as I am new to photography.

Does anybody know what 012 mean engraved on the lens?

no worries, we are always here to help each others

your shots seem fine

if you want to reassure yourself, print a chart on a A4/letter page with a scale (-2, -1, 0, +1, +2) or with a text

and try to focus on the center or the text, it should be sharp

use a tripod to avoid hand shaking

but based on your shots, it seems fine

Heya,

Really great photos, your copy is a great copy, looks like the AF is working great and the crispness at near wide open is very good and it's nailing it in low light.

Winner.

Very best,

Thank you. I think so too....looks accurate to me. Still...need more time, but nothing worrying at the moment.
