Pentax DA* 16 50 worth it?

Hy all,

i have stumbled uppon the lens mentioned in the title for sale for a more than reasonable price ( aprox 400$ with a make offer posibility) but the item is sold as spares or repair because the af is not functional, other than that it seems in perfect condition.

I know this lens is famous for its weak af motor, so my question is:

- i know it is possible to convert to screw drive but is it possible that the lens has other problem?

- is it hard or risky to convert to screw drive

- and lastly, what is a good price to offer for such a lens considering the risks

Thank you in advance for your help.

I'd say look for a better deal. You can find this lens with working motor in very good/like new condition for 300-500.

I found one for myself for 300 a month ago and I really like this lens.

I got a Tamron 17-50 f/2.8 instead. As far as i've seen, people say the image quality of the 16-50 wide open isn't that great, so I wouldn't go for it unless you need the WR and the good looks

It can be had for around USD250 used.

I do not care that much about f2.8. I am more interested in wr because in Germany it rains a lot, and when not, it is cloudy and humid.

I saw what u guys in the U.S. pay for gems. Here everybody has internet and everything is a bit overapreciated, so we have to pay up for everything.

The process for conversion to screw drive is not hard and if that is the only thing wrong with it, it may be worth it. I own a 16-50 and have been pretty happy with it. Biggest problems are weak borders at f2.8 and a tendency to flare. Otherwise, the colors are what you expect from a solid Pentax lens and it works well.

I think 350 would probably be reasonable considering you are taking a chance that a screw drive conversion isn't guaranteed to fix the lens.

It's worth $200 bucks broke if that. Walk away from that bad deal.

Thank you all for the good feedback. i am going too pass on this one.

I am having a tough time deciding between what i want and what would be more convenient to use. so many variables. a lot of people say pentax has not enough lens choices but for me there are too many. I know a lot of you would say go down the da limited path, but that one is long and costly...

anyways, im not in a rush, i will decide at the next possibly good deal.

The two best WR standard zoom choices for Pentax APS-C K-Mount are the DA* 16-50 and the DA 16-85. The DA 16-85 is a more recent offering, and as a result it's going to be harder to find good deals on that lens. But in terms of image quality, it's reputably very very close to the DA* 16-50, with longer zoom range and better flare control, but much slower in terms of aperture.

If either of those choices are too pricey, the next best WR choice is the DA 18-135.

If f2.8 isn't a concern for you, I highly recommend the newer 16-85mm. I loved that lens before I sold it (to raise funds for the K-1).
It pretty much trumps the 16-50mm in every regard other than aperture.

I see nobody is showing love for the 20-40 limited, is it that bad?

i also took that in consideration at one time, but from the reviews it seems a bit bipolar

I had one for a little bit... It was ok, but I couldn't fall in love with it. To me it wasn't wide enough in the wide end nor long enough on the long end.
IQ was good, not stellar. And it is not a small lens for covering such a short range and being variable aperture.
