If you read my signature you'll see that I've only bought the high performance lenses that come at a value price. I don't have a lot of money to throw at it. But, I have a lot more lenses than are listed down there and I'm thinking of unloading some. Let's face it, price vs size vs quality there are hardly any m4/3s lenses that are worthless (except some of the 14-42s because the P14-42 mkII is better, smaller, and the same price). So, when I say I want to sell something, it doesn't mean it isn't useless, just that with other lenses, it doesn't get much use. For example, the Sigma 30 is a terrific lens. I hear it's the fastest focusing m4/3s lens and one of the sharpest. It's definitely one of the best deals out there. I got mine new for $130 and could easily sell it for that. I feel like if I sell it I will want it back some day; for some reason. Now all I use it for is taking ebay shots; which I will stop doing when I buy the 20 again (when I want a long normal I use the Vivitar 28/2 because it's just as sharp and a stop faster than the 30). Then there's the 11mm wide angle converter for the 14. This set up is outperformed by the Samyang fisheye after defishing. I don't need it at all; but I paid under $100. Then there's the 14 itself. Great value lens, but the 12-32 is just as small, sharper, less distortion, and wider. But then you think, wait, the 12-32 is 1 stop slower at 14mm (but when I pop the aforementioned 28/2 on the Sony A7 the 14/2.5 is thoroughly beat [but the 14 is sooo tiny!]) Anyway, have you sold any lenses that you regretted getting rid of?
