DA* 16-50mm Serial Number Database.

Buddha Jones · 03-07-2008, 04:02 PM

OK, so I guess this is a long time coming, in an attempt to keep the histeria to a minimal, lets start keeping track of the good and bad serial numbers so we can try and see if there is a trend base on some facts rather than speculation.

Please help out, if you have a DA* 16-50mm please post your SN# here and wether it is a good or a bad copy and if it's a bad copy where you got it from. This will help to keep count of bad vs. good and perhaps build a corrolation with the serial numbers as well.

Thanks.

Future serials should go here: SMC Pentax-DA* 16-50mm F2.8 ED AL [IF] SDM Serials - Pentax Serial Number Database - PentaxForums.com

Ill start out.

Mine is a good one, and my serial number is 9011133. I got mine used from a forum member.

From this post:

SN 9018018

Well so it seems that the QC issue still hasn't been resolved yet in later model.

9018018 from Amazon was NO GOOD

**Canada_Rockies** · 03-07-2008, 04:33 PM

Serial number 9013067 is a good one.

cafinator · 03-07-2008, 06:42 PM

Serial 9021117 is good

**Dice** · 03-07-2008, 09:24 PM

First bad one was SN 9017292 purchased from B&H and I just got the second one today at 1pm and after an afternoon of shooting and evening of testing 9018380 it is a stinker as well. It severely front focuses as you move from 50 to 16mm. Also from B&H. It is going back next week. I'm leaning towards asking for a refund at this point and not waiting another 2 weeks.

9015921 is pure "doo doo" SDM doesn't work anymore, got it in Canada from my hometown store.

If you do not know if it is bad then I guess it is a good copy

It either has back or front focus, coupling with the very noticeable softness at wide open.

S/N 9012269 is a good copy. Purchased from a Pentax retailer in Helsinki in October.

**Tyama** · 03-09-2008, 09:23 PM

Serial number 9017115 is good as far as I can tell

AlanR · 03-09-2008, 09:49 PM

9019612 good, no problems, and I am beginning to wonder if there isn't some mass hysteria going on about this lens.

ryan s · 03-10-2008, 09:22 AM

It's just a good idea to keep track in case a certain retailer is hustling the same lens as it's returned for faults. Also we might see a correlation in resellers having lots of bad copies.

I was hoping to see some relationship of bad SN's to good SN's...none so far. Still holding off till summer to decide if I really want one.

I have 9013251 and its a good copy.
