The following images were taken with the above camera/lens combination (unless otherwise stated). It was my holiday combination of choice during my visit to Cornwall, UK during the rainiest June in recorded history . This is where I noticed some strange behavious from this lens. If you look at the bottom right of this image you can see that it's not what I would call, very good. This happened at shorter focal lengths and it could be seen either on the left or right side of the image. So it's not something I could really nail down. It didn't happen all of the time and is something that's still got me thinking about it after a few months. Not certain if this lens is one that I can count on. I think I'll switch to either my Fuji system or M43 again. Another negative for this lens is the space it takes up. Not exactly what I call light either.
