I have three or so samples taken with the new Panasonic 14-140 f3.5-5.6 lens. This is the second version and not really optimized for video. I really wanted to like this lens because I like the zoom range and it has a better feel to it than the first version. It is also smaller and lighter than version 1. However I may have gotten hold of a dud or as I call it "a Monday morning lens". Now these images I'm posting suggests that the lens was fine but these are only a few of the ok ones I got after using the lens for over a week. What I was seeing was really soft images using this lens on the E-M1 and I just couldn't figure it out. One minute I got some sharp images then the next few images were really really soft, and not only at the long end.
I tried switching from IBIS to ILIS but that didn't help matters at all. There was no pattern as to when a sharp image would appear because most of them were soft. The fact that this lens must have come from a kit because it actually came in an envelope, which didn't really help my confidence in the lens to start with.
To cut a long story short, the lens got sent back for a refund but I really did like the lens as such. I just might try another one down the line because it would pair up with the GX7 nicely.
