  • Sony FE 28-70mm f/3.5-5.6 OSS SEL2870

    3 out of 10 points and not recommended
    Very soft away from the image center

    I am not sure whether to blame the lens or the very short flange distance on the FF Sony cameras for the poor performance that this lens shows away from the image center. I tried two copies with the Sony A7 II and they were both similarly poor. Since the flange distance on the Sony FF cameras is very short, it would not be surprising that the problem is with the camera and not the lens. Reviews of the other FF kit lens (FE 24-70mm) seem to show a similar problem with softness away from the image center.

  • Olympus 12-100mm f/4 IS Pro M.Zuiko Digital ED

    10 out of 10 points and recommended
    Sharp, Great IS, Very wide zoom range

    I've only had this lens for about 3 weeks - and I do not do any type of testing other than actually use the lens in real life situations - and so far I am very impressed. The range from wide angle to telephoto zoom is extremely handy. Normally, in order to have this type of zoom range, lenses have been optically compromised. That Olympus was able to produce this lens and have the sharpness and overall quality be so good thru the entire zoom range is remarkable. And the IS - combined with the Olympus IBIS on the E-M1 - is really an eye opener. I took a few hand held shots with a 1 to 2 second exposure and they were sharp. I really thought similar comments I had read about the IS in other reviews was just hype - but it is real! Probably the best lens I have ever owned - by far!
