Hi guys, i just got quite a good offer on a Vivitar lens, its the Wide angle 28mm MC version that has the filter thread of 49mm that is offered to me for around USD55. Question is, is it a good lens in terms of preformance and overall quality? and is the market price overseas similar to this? cause from my experience, most sellers in Malaysia is pricey and after asking from APUG forummers, then i know whats the actual price like. Its not that i dont want the 28mm from Nikon but its way to pricey and my budget is not that high at the moment (seller selling to me at USD340!!!!) CRAZY HUH?
