I recently moved to Bangkok and brought with me my Sony NEX 5N/kit lens combo. It was from living here that I finally started to use my NEX 5N for the first time and began spending my free time learning about photography/cameras/software. From this new experience and education, I decided recently to upgrade. I found and purchased a used Sony NEX 6 body (no kit lens) with a Sony SEL 16/f2.8 about two months ago. Additionally, after my purchase of the Sony NEX 6, I purchased a Sony SEL 50/f1.8 lens. It was from this single purchase that I personally discovered the importance of lens selection. Here is my situation...living in Bangkok I do a lot of travel/city/landscape photography, but I have only the SEL 18-55 kit and 16/f2.8 lenses for travel photography. My SEL 50/f1.8 is amazing and I love the bokeh created when I'm photographing people, but it's not a good lens for travel photography. I want to sell both my Sony SEL 16/f2.8 and 18-55 lenses and upgrade to an all in one travel zoom lens that offers better IQ, while hopefully producing good bokeh. I am considering six options and can't decide which to choose. My considerations: 1. Sony SEL 18-200 ... good quality, best focal length, but larger in size, priciest of options 2. Sony SELP 1650 ... compact, cheap, but still a kit lens and reviews are average and not great focal length. Can get used on ebay (China?) for <$150. From what I read, it's not much better or maybe equal to that of my SEL 18-55 kit lens. 3. Sony FE 24-70 (A7 kit lens) ... Not wide angle, but decent reviews 4. Sony SELP 18-105G ... not many reviews so jury is still out, power zoom (don't know if this is good or bad), good but not great focal length, heavier, but not heaviest of options 5. Tamron 18-200 ... cheaper than Sony version, lighter than Sony version, reviews show that IQ is not equal to Sony SEL 18-200 but not far off, like the Sony SEL lenses mentioned here, this lens also has image stabilization. 6. Sony SAL 18-105 + LA-EA2 ... A local camera store in Bangkok has this combo new for around $550. 1. Good: A) Surprising not the heaviest compared to above. B) Good to great reviews of both he lens and adapter. C) Adapter opens up my lens options to include a-mount lens. D) Adapter gives my sony nex 6 phase detection. 2. Bad: A) Lens introduced to market about 11 years ago so not the newest of lenses. With the SAL 18-105 I lose OSS/image stabilization. 7. Do nothing. Sell the Sony SEL 16/f2.8 with the Sony NEX 5N body. Keep and use the kit lens Sony SEL 18-55, until prices come down or new lenses are introduced to market. Thank you for taking the time to read this and I hope you more experienced and knowledgable members can help an aspiring hobbyist out.
