With the new Sony E 16-70 attached to my NEX 6 (see prior post), I walked out the door with two camera-lens combinations to test against each other. The other combination was an Olympus E-M5 with my oldest digital lens, the well-respected 14-54ii designed for 4/3 cameras. I used it with the Olympus adapter to fit the 4/3 lens onto the m4/3 mount.
|The Olympus is on the left. With the 4/3-to-m4/3 adapter the Olympus 14-54ii zoom|
weighs 17.7 ounces and is larger than the Sony lens.
The Sony lens weighs 11 ounces.
The 14-54ii has been my favorite zoom for many years, having been with me previously on an Olympus E-520 and E-620, and a Panasonic G2 and GH2. With an effective focal length of 28-108mm it's been (almost) perfect for me for travel, landscapes and people pictures. However, the Sony is equivalent to 24-105mm, and it is the 24mm-equiv. wide angle that attracts me to it. Also, it focuses much faster and far quieter than does the Olympus combination. I didn't test either one for video.
For me to keep this lens it must be at least as sharp as the 14-54ii, both in the center and in the corners. (Otherwise, it is going back.)
Tonight I will evaluate the results of my little "shoot-out" and publish my thoughts in a follow up post (hopefully, tomorrow).
