Where did you find them? Can you give me the website?

18-200mm

according to the MTF chart, 18-200 seems to have good image quality (at least not bad) among this kind of lens. But the result among people who use it is rather poor. What makes this difference？

I love my 18-200 on my Galaxy NX. It's heavy, but at 18mm I find its IQ highly enjoyable. Corners are softer, but the lens has its own unique rendering.

As you zoom in, edges get kind of crazy but my copy has very good center sharpness (non pixel peeped) throughout the range. At 200 it almost looks like you're shooting through a blurry tunnel but center sharpness is still good enough.

OIS is very good, I was surprised.

Technically, pixel peeped, I'm sure there is plenty wrong with this lens, especially with the edges. But from a uniqueness-in-rendering point, this lens scores high for me. I was sceptical when I bought it, I already had the 50-200, which is technically the better lens. But I fell in love with the 18-200, I very much enjoy its output. I'm not sure how it does on an NX1 as the 28 MP sensor probably outresolves this lens, but my Galaxy NX and this lens makes for a very enjoyable combo.

I also own a Panasonic G9 with the 14-140ii lens. While that lens is classes above the 18-200 in edge sharpness, I find myself grabbing my Samsung setup more frequently, but only on sunny days. Looking at the pictures at home I get less keepers but also more select 'wow' factor images.

I'm also a fan of the 18-200mm. You're right it's probably not as good technically as the 50-200mm but it has some real advantages. The most obvious is that it starts at 18mm but also the autofocus system is better and quieter (good for video) and the OIS seems better.

It's the only lens in the system that truly makes the camera a 'bridge' camera. I use it occasionally with my NX1 and I'm happy with the results. In fact I'm on the look out for another copy - mine came without the hood (which is impossible to find separately), the front element has some marks and the lock switch is broken!
