Is it normal for needing 50-135 lens repaired twice?

Hi Beth, The "noise" isn't excessive, just standard for a the older style of lense. In a wedding, doubt anyone will notice the noise or find it out of place. BTW, someone on this forum posted a procedure to convert the lense to screw drive yourself. It was very simple to follow and worked like a charm.

- the 50-135 is an SDM lens meaning that it has a motor in the lens that moves the elements into focus. It also has the ability to use the older in camera motor which is far more reliable. However it will not that automatically but it can be done. The result is that the faulty in lens motor is bypassed. The downside is that the AF is somewhat nosier.
- A number of SDM lenses (16-50, 50-135 and 60-250) have had a poor reputation for failure. Supposedly newer lenses have a different motor that is more reliable.

- the 50-135 is an APS-C lens and is not capable of covering the image circle of the K-1. So if you are planning to buy a K-1 you will need a new lens for that camera. If you are keeping your current body then replacing or repairing your 50-135 for that body is a good idea. But if you are moving to FF with the K-1 then consider selling the 50-135 "as is" and get a new lens for the K-1

The K1 is full-frame. The 50-135 is APS-C format, so while it will "work", you won't be getting all the camera has to offer. If you are upgrading to the K1, you are probably going to be wanting different lenses all around.

As to the other question, there are two focusing systems in use: in-lens motors (the SDM in the 50-135 is an in-lens motor), and the in-body motor (also called screw drive commonly). The oldest Pentax autofocus cameras only had screw-drive, and they do not support in-lens motors. Because of this a few SDM lenses, including the 50-135 are capable of operating with either method. However, if the lens is attached to a modern body, it only wants to focus in SDM mode, not in screw-drive mode. There is a 'hack' of sorts where one changes the firmware on the lens so that it always thinks it's on an older body so it always uses the screw-drive. The downside is that it is a little noisier. The upside is it is nearly 100% reliable and should last more or less forever. If you have any older or more affordable lenses that make more noise when focusing, those are screw drive. That's pretty much what a converted 50-135 will sound like. It's not terrible, and it's a low-cost solution to your problem.

One of the users on the forum, Uncle Vanya, will do the conversion for you for a modest fee, and return your lens to you functioning with screw drive. Send him an IM and I'm sure you can work it out with him. You can find a posting from him in the marketplace here on the forum:

Hi Beth, I bought a used 50-135 and the owner sent an invoice showing the focus motor had been replaced. Without getting specific on dates, within the year, the motor failed again (slowly then totalled) and sent it in and had the motor replaced. Within a year, the new motor failed again (that would have been motor 3) and did the same debate you're going through. Decided to convert it to screw drive and have never looked back. A little noisy but it's quick and accurate nwo. Discussing the motor issue withe repair shop it was more or less a discussion they can only repair with the parts available and if those haven't been improved at the manufacturer the problem will continue. They actually indicated it wasn't the motor proper but something to do with th electronic controls that needed to be constantly used to keep functional.

If either of you has a Starbucks nearby (or any other place with free, secure WiFi, next time (July Giveaway) try going there with your laptop, tablet or phone and accessing the Lottery Thread at the faster speed.

Adam tweaked the rules a bit so there are four times rather than two and the thread accepts 75 posts rather than only 50.

This is one of those things that has to be measured with the utmost degree of care. Otherwise the adjustments may actually backfire.

I strongly recommend using the professional tools unless you are comfortable making a custom rig with proper alignment and good targets.

It does kind off suck, it seemed to open around 7:05; which means I was mashing the F5 key for five minutes straight.

That was what I saw, kept refreshing and reopening and eventually got a "post a reply" window (three minutes or so after it was due to open) but by the time I posted all the tickets were taken.

I'm assuming the software was swamped by responses, well at least I've saved the accountant the $400 import duty by not having the potential to win....

Good luck to those who did enter, congratulations to the eventual winner, and I look forward to seeing the images.....

It certainly was a frustrating experience with only one and then two posts while staying closed to me getting a post in.
Certainly makes me think I will not bother trying next month.

Also I saw two mods had entered whilst the thread was still showing as Closed. Don't want to appear all "sour grapes" but something doesn't smell right!

I didn't get in but I did hear a Pentaxian on NPR this morning - mattb123 (Matt Burt). That was kind of fun, though it's the weird feeling of "knowing" someone only via forum posts.

if the contest and the posts necessary to trigger it got you ( and others ) back into the forums

I am very glad

I chose not to try for the K 1

bottom line, I don't want one and I have had problems trying to get to the forum ( but not my other sites ???)

I feel you! I pay for what is considered fast for living in the sticks but When I try to Sling my hockey to watch on my computer, it is terrible quality and stream wise. On my Fire TV box that is next to the router, it rarely stutters. I have 15 feet of Ethernet cable and I am supposed to believe that is the issue? Going to a local company that charges less for more that has transmitters and receivers on nearby cell towers. I may lose internet in large power outages if I do that though.

You would not be disappointed. Very intelligent. Also very independent. Comes from a few hundred years protecting goats and sheep high in the Pyrenees Mts with no human to give orders. They made their own decisions and that trait remains with the breed today. Sometimes I'd want Cider to do something and he'd give me this look like "yeah, I'll get back to you on that." :) They also bark a lot at night. Their way of letting the bad guys, both two and four legged, know that there is no easy pickin's here. Move along. But their demeanor with other animals is amazing. All our goats, both young and old, sensed there was nothing to fear from Cider. Other dogs on the property made them very nervous. But not Cider. The does were even more than happy to let Cider help clean off a newborn when he chose to. Sorry. I could go on for ever telling Cider stories.
