I tested my copy (bought used) and it appears to be adequate at all focal lengths for sharpness, etc on my A7C for casual shots.
Here's a shot into the sun for reference.
Sorry wo warm up this old thread. But: It was crucial for my decision on this lens. I just heard some days before about this little "piece of air", researched a bit, and wasn't so impressed with most of the photos people loaded on flickr. At least it didn't fit with all the praises I have found across in reviews or forums. Then I found that forum and saw the test series. And this photos on the opposite were unbelieveable sharp, even in the edges. I`m sorry to say that, but as I never was on that forum before, I really thought this photos were faked and Fred Miranda made a joke about that all. But why should he?? So I bought a used Sony 28-60 to check it myself, because even it was much more unsharp then this photos here, I think I would have loved that lens for its size. And woooh: It`s image quality IS amazing!! The photos are that sharp, the rendering is really nice! I just have it 1 hour and love that little ting. If that is the future of lenses, I`m very curious about so many re designs of todays bulky lenses. I just was in my early days as pupil into this heavy lenses, soon I saw its disadvantages for every day use. And now that! I`m happy. Thanks for this report here, it has an important impact on my future photographing!
I got the 28-60mm on the used market for 200 CAD (around 150 USD) 1 year ago. Very impressive little lens: sharp, instant AF and weathersealed. It is a lot of plastic, but I love plastic when it is this light. Now, if Sony could bring a similar 60-200mm for a good travel setup... Meanwhile, I add the Viltrox 14mm and the Tamron 70-300mm RXD to my bag for a small setup that can tackle almost anything except low-light. For this, I can add a small Sony 35mm f/1.8.
