Pentax 17-70 f/4 sdm & Pentax-A 35-105 f/3.5 Marketplace Listing

Item for Sale
Pentax 17-70 f/4 sdm & Pentax-A 35-105 f/3.5

Asking Price
200.00 USD

Item Location
MO (United States)

Item Description
I am selling or trading this two lenses as a pair for $200.00
The Pentax 17-70mm is in excellent condition, BUT, the sdm motor is going out, or at least that is what I think.
I am still using the 17-70 but it is becoming too much of a pain to use as a auto focus only. The sdm motor seems to be getting slower, to where I have to move the focus ring to infinity to get it started again. It has to be sent in for repair or used as a auto/manual focus lens.
I have a Pentax 16-50 2.8 that is doing the same thing, so I will send the 16-50 to get a new sdm and try to sell/trade the 17-70 f4.

The second lens is a 35-105 3.5 lens that I use as my manual lens. This lens is in fair outward condition but works fine. The lens zooms and focuses very smooth and the blades are dry and snappy. No haze or fungus on the glass. This is my only manual lens, but I do not use it enough to keep it around. I have tried to use it with my five year old but it is hard to keep up with him trying to focus manually.

As a trade I am looking for a prime lens (auto focus) somewhere between 21mm and 40mm. I do not want the 35mm 2.4 or the 40mm xs. I guess I am looking at maybe getting a 28mm 2.8m, 30mm f2 or 40mm 2.8 limited. I would also go for a 100mm macro lens. I would add some money if needed but cannot spend much since I still have to send the 16-50 in for repairs.

If anyone is interested send me a pm.

It has not been converted to screw drive. I was trying to find out if I could do it with my k5 iis but could not find an answer.

I have done that on my 16-50 and 50-135, although the SDM on both were still working fine. I was worrying the lenses would gave up during an important event and converted them. I feel (might be wrong) the screw drive AF is faster than SDM and is not that much noisier so I kept them on screw drive.

If you want, you can mail the lens to me and I can try to convert it for you.

Hi grahame,
Thanks for the offer, I might take you up on that. I have a big family reunion in Colorado for christmas and was wondering if CRIS would be able to fix and return it to me before that. I would like to use the lens then, so If you could send me a message with your info that would be awesome. I will send you one with my phone number after work.

I am lowering the price to $180.00 for both lenses or trade towards a 28mm to 40mm prime.
