Good morning, I've got a problem that I would need to fix, but actually cant.
So, for the first I got a Canon 70-300 IS USM lens that i bought on B&H in New York last month. When I frist tried the lens at JFK, it worked out just fine, the pictures was sharp even trough it was cloudy and the photos was taken trough a window. I'll show i a photo.
But when I got home to Gothenburg, Sweden and started to spot at my local airport (GOT) I noticed how the photos were imo really bad sometimes. Almost every photo is now blurry and dark, and it seems the photos get more worse every time i take photos. I'll show you a photo from the last week. And also, the settings is almost the same in booth photos.
What do you think the problem is? It's really sad, cause beofre I bought the lens i read all over the internet about it, and everyone told me it would work better than ex Canon 55--250 IS.
