Sorry, not really an alternative lens, but this is driving me insane almost. To me, this is clearly faulty, but I\'m trying to describe it to the people I bought it to and I\'m just repeating myself.... I\'ve sent them this photo.
The lens is at 11mm, manually focused all the way to infinity, as far as it can go. It is at 2.8. I take a photo, and review, but upon inspection the photo doesn\'t seem right. From around 5-7 feet seems the point of focus and then... to me.. the distance, infinity, seems clearly out of focus. With the lens focused as far as it can go, this suggests to me that it is faulty, poorly calibrated - no?
I\'ve had it a few months, and hadn\'t noticed the problem before (yes, silly me), but I\'d only used the lens at f8-16 before whilst at infinity, and wider apertures for closer images... hence why I hadn\'t actually seen the issue. However, it has a 3 year warranty, so I\'m hoping they can just repair/replace it, despite the long time. It\'s not like it\'s been heavily used, looks like new really.
Thanks for your help...
