[SOLD] Sigma 30/1.4 Marketplace Listing

Item for Sale
Sigma 30/1.4

Asking Price
$300 shipped

Item Description
Excellent condition Sigma 30/1.4. Has zero focusing issues on my K20D (Sigma quality control on these was bad, but this is one of the really good ones), tack sharp wide open, fast focus, rock solid EX build. Excellent "normal" for a crop body.

Please note that I will ship within the US only -- I've sent some items international and it's been a bit of a hassle using USPS.

If anybody sent me a PM when I had it for trade and didn't hear back, my apologies. I thought I had it and the K20D sold but the buyer backed out a week later and by then I had deleted most PMs.

Are you the original owner of the item being sold?

Are you selling or trading this item?

I've heard about (and read reviews) of these having kind of lousy sharpness nearer the corners, would you attribute that to the bad quality control, or just the nature of the beast? I'm sorta shopping around this range, and finding I rather want the speed if I can get it.

I too heard that and was convinced enough that I thought so too initially. However, the reality is that when shooting near wide open the depth of field is so shallow that you never really have the corners/sides in focus anyway, so the softness there might be doesn't really affect real world shooting. Stopped down a bit it's perfectly fine across the frame.

edit: also good chance that some reports are because of QC issues, while I love Sigma glass when it's good I gather the US reseller tends to just send out lenses that have been returned so the same crappy one might go through the hands of a half dozen people making things worse...

Here are some samples...

with 100% crop (a little noisy, think it was ISO 1600):

On this one, I can zoom in and see my reflection clearly in her eye... at 1.4!

Finally got my camera to test out this lens, it's great! I have a feeling this will be my most-used lens for a while
