Summary: ORIGINAL REVIEW: Do not buy this lens for a Sony NEX 6! In theory, it's just fine, and it worked fine when I received it, so I set it aside for an upcoming vacation. The first time I tried to use it in the field, though, the camera would not recognize the lens, would not focus, and would not shoot. Google the thread "sony nex 6 lens not recognized" and be warned. The lens is apparently made loose and the contacts don't connect well -- at least to the NEX 6.
Summary: I flatter myself that I'm an "advanced amateur" photographer for over 50 years. I'm quite used to Canon DSLRs and their lenses, and to Sony E mount prime lenses. I really wanted this lens to work, because the focal ranges were exactly what I wanted. I spent many hours and hundreds of exposures trying to "learn how to use it" - but in the end, I returned it, because I could not get an acceptable percentage of "keepers" with the 55-210.
Summary: While I enjoy using this lens, it's soft at 210mm. At first I thought I had a defective copy, but the reviews seem to say this is a common issue. It's still a decent lens, but the softness does limit it's usefulness for wildlife photography.
Summary: This lens is neither overpriced nor a bargain, it's pretty much what one would expect from a telephoto zoom in this price range. I compared this lens against Sigma 50-200mm/3.5-4.5 APO lens. The resolution of Sigma lens both at the center and the corners is noticeably better at the same f-stops and focal lengths. Moreover, Sony's resolution is degrading at the long end. Contrast looks or less the same for both lenses. Sigma's bokeh in my view looks better.
Summary: SONY SEL18200 E-mount 18-200mm was my telephoto zoom lens, and it's very heavy making me feeling like to carry pervious Nikon DSLR when it plugging on NEX5N. After I received this E-mount 55-210mm len, I would say that SONY got the right point to create this len for working with 18-55mm kit lens. 1. Lighter, it's the most key point to use NEX5N instead of tranditional DSLR. 2. Faster, auto focus is faster than SEL18200. 3. Cheaper, the price is reasonable. 4.
The only NEX telephoto zoom lens without getting a converter
28 June 2013
Summary: Really, this is the only Sony NEX e-mount alternative for a decent telephoto. It's quite sharp but at the long end of the zoom the aperture is quite restricted and require some manual compensation in certain conditions. This is really a travel zoom more than a portrait lens due to the aperture restriction. However the price is decent for what it is but I wish Sony comes up with a bright telephoto zoom for NEX.
Summary: Tuotteen mekaaninen laatu on hyvä. Tarkennus- ja zoomirenkaat toimivat sulavasti, kuten uudessa objektiivissa pitääkin. Painoa ei ole paljon, mutta ei kuitenkaan tunnu aivan lelulta. Kuvanlaatu on verrattavissa NEX-kameroiden mukana yleensä tulevaan 18-55mm kittiobjektiiviin. Ei siis mitään tajunnanräjäyttävää, mutta ei kuvien hyvyys jää varmastikaan laadusta kiinni. Polttoväli riittää esimerkiksi lintukuvausharrastukseen mielestäni mainiosti.
