Overall I think this lens is a keeper, it's small, light great build and optical quality. But it does not focus anywhere near as close as people claim. It is quite disappointing in this respect. For example the Fuji 18-135mm zoom lens focuses far closer than this lens does. I think that this lens is better than the Olympus 45mm f1.8 lens and I had both. Note! I have since sold my M 4/3rds system.reviewed November 5th, 2016 (purchased for $270)
8 out of 10 points and recommendedValue HandlingEdge softness at 17mm and 35mm at f4
I have only recently purchased this lens to use on my Canon 6D. I had, loved and sold the Canon 16-35mm F4 IS lens due to lack of use, ( I found it hard to justify having a $1349 AUD lens just sitting there as I don't work). So I sold it and purchased this lens as an ex demo from an Australian store for $220 AUD. I carried out some basic tests with an ISO test chart and was pleasantly surprised.reviewed February 12th, 2017 (purchased for $220)
I found that the lens was quite soft in the corners at 17mm at f4 and still soft at 5.6, but quite reasonable at f8. At 21mm the lens is soft in the corners at f4 but at 5.6 it is good and at f8 sharp across the frame and at all focal lens f8 is the sharpest by some margin, with f5.6 from 21mm to 28mm good to very good across the frame. At 35mm the lens is again quite soft in the corners at f4 and gets to be good across the frame at f8. The lens is at it's sharpest around 21mm, with 24 to 28mm not far behind. 35mm appears to be the lenses weakest focal length.
Overall I think this lens represents good value at it's retail price of around $600 to $700 anything less than that it's a bargain.
