Front focus issue with 35mm sigma And nikon D700?

Hello. i just receive the sigma 35mm f1.4 and taking some sample shots i notice that sometimes i loose some focus. and i wanted to make a better test using tripod to find out if my lens have back or front facus issues.  I used the lens with the nikon d700 in a tripod using F1.4 and timer. scene is 5 batteries. I took 5 photos . Each photo must have in focus one battery starting from the left. First photo  - first battery from the left is in focus, Second photo - second battery from the left is in focus etc. I am not sure from the photos if i have front focus issue so i want your advice. I made a crop to the photos so the batteries will be close up. I can see that the lens focused correct but maybe there is a little front focus? or its my idea?
