Hello: I hope someone can help me with my lens issue. This past weekend, I rented the Zeiss Batis 25f2 so I could see if I liked it well enough to purchase for my Sony A7. While I loved many things about the lens, I was disturbed that during a night photography outing, my photos showed what I think is "lens flare" --please pardon that I am not all that familiar with the technical side of lenses and the names for particular issues -- and I could very well be describing something else. I used the hood that came with the lens and a clear glass filter to protect the lens during the night shoot. * The settings for the picture of the railroad tracks with the odd object growing out of the flood light were ISO 100, f11, 97 seconds. * The settings for the picture of the canal, long factory building in the distant left, and the moon with a green tail/halo were ISO 100, f11, 8 seconds. I have used other lenses during night shoots and while the flood lights were bright sunbursts, I never had the halo affect around the moon or odd objects growing out of the light sources. I know this lens is very new to the market-- so few people own one... but I'm hoping to get some clarity before I purchase or decide not to. My questions are: 1. Is this something particular to certain lenses-- basically what you should expect from that lens, or could I have rented a damaged copy? 2. Can anything be done post processing to eliminate what I have described/shown? I just got Lightroom but I don’t yet know much about it. 3. Is there anything to do when taking the photo so that this issue can be avoided? Thank you so much for your help.
