SMC DA* 16-50/2.8 non-SDM Screw Driver AF (Final Price) Marketplace Listing

Item for Sale
SMC DA* 16-50 with Disabled SDM (Now Screw Driver Mode)

Asking Price
549 USD was $700. For quick Sale, need money now for portrait lens SALE PENDING

THIS IS THE FINAL PRICE here, I will put this lens on eBay auction if it doesn't sell for 5 days.

Item Location
California (United States)

Item Description

** I Have Uploaded 100% Crop, 16mm/F8.0 on K-5 RAW. you can see that, it is actually very sharp. It's a great lens for shooting in practice. For comparison, I put a 100% crop of 17-40/4.0 on 6D at Center here as well.***
As Requested, I also added 50mm/F4.0 100% crop, which is considered the cons of this lens, for comparison, I added 100% crop of Canon 70-200/2.8 on here

I am kind of a software engineer so I disabled the SDM and enabled screw driver AF because I just got enough of it (Now AF is super faster and more accurate, will not hesitate focusing, of course, nosier than SDM). You don't have to worry about a failing SDM anymore, the AF will always be there. Now, this lens basically has no down side anymore.
Some minor dust inside lens, few scratches on lens body ( not on glass ). Come with just the two caps and lens hood
I don't have a earlier camera now, so I can't restore the lens rom. SDM is working last time I ever used it.
According to this thread: , the price can be $50 higher than normal SDM lenses, I put this lens below the average price range for quick sale since I need money for purchasing a portrait lens or update camera.

Any Pentax body with screw driver AF will be able to use AF on this lens.

The Lens is sharper than Sigma/Tammy at wide angle with F8.0 aperture and 50mm at center with F4.0 aperture. Since you either gonna stop down for deep depth of field or use longer focal length for shallow DOF, this lens is better than other rivals in real life shooting. MTF graph from Photozone and DxO proves my point. Since I got rid of the SDM problem, this lens is like perfect.
Color of this lens is as good as A50/1.7, vivid and gives a solid feeling like Pentax always give you, much better than Sigma and Tammy. (see pics).

$549 insured shipped to any U.S. Location , PM for international shipping. [COLOR="Green"]

Will trade DA 70mm/2.4 , Sigma 70mm Macro, DA*50-135(dead or live sdm), Sigma 50-150/2.8. Other 50mm+ AF lens for portrait.
