Originally posted by arbutusq Great thread. I and the fiancee are planning our honeymoon in Turkey and I am agonizing over which lenses to get for the trip. Currently I just have the 18*55 and 55*200. All of your advice to the OP has been very helpful to me.
Now I just have to make up my mind. Does anyone have experience with the Sigma 18-50 2.8?
I am sure this was discussed before (I cannot find where the threads are in here). In that thread, Sean (carpent) had stressed the preception of sharpness based on what the standard "sharpness" is etc.
I tried the lens before on canon body and I did not purchase the lens. Most of the experience are from readings (like similar to most lenses) are images "softer" wide open at extreme focal length. This lens does vignets a bit especially at 18mm. Bokeh are "tubular" or "linear" depending how you call it. Otherwise it is still a good lens to use.
Why don't you consider the forthcoming supersonic and weather sealed pentax 16-50mm f2.8?
