A couple of months back, I was planning to get a zoom lens. Checked with shops and got a rough idea on how much a new lens will cost. Then later found this Sigma lens in the "Buy and Sell". The price was ok and I managed to get it lowered a bit. Arranged with the seller to meet and test lens.
Here's the problem. I wasn't good at testing lens at all and just tried a few things in P, Tv and Av mode. Some pics came up not so good but because it was a cloudy day (just finished raining), I thought its the poor lighting causing it. At the end, paid for the lens and was happy. Until.... when I use the lens to shoot the fireworks, there was absolutely no difference in the pictures when I change the aperture setting in M mode. Eventually found out the aperture is always wide opened regardless of the setting.
Choice was either throw it in the bin or revive. Ended up paying $120 to get Sigma to fix it.
I cannot blame the seller completely 'cos if I tested the lens more, for sure I can see the defect. At the end I could have spent the same amount of money to buy a new lens. Money aside, the rest of the bad experience :
1) wasting time to get the lens fixed,
2) shooting bad fireworks pics, again, wasting time, and
3) the seller gave CS a bad name! Very disappointed. Dunno if I will ever buy from CS again.
Hope all bro and sis be careful when buying 2nd hand.
