Has anyone used these folks...

https://www.pentaxcamerarepair.com

$100 seems fair and it is a pretty easy repair from what I'm reading. Unfortunately I fly to China in 2 days so I'm going to have to wait and hope the camera is still usable on the trip. I'll take my Km as backup and I also have a a Canon Elph 350 (20mp) .


There's lots of info regarding the fix for this problem in the K-30/K-50 forum. Regarding the repair by this person, it's said that he files/sands the problematic solenoid horseshoe and that this isn't a permanent fix. That is, the problem can return and possibly cause additional problems. He does however give a one-year guarantee.



If you have a lens with an aperture ring, you can set the aperture on the ring and then use the green button to set the appropriate shutter speed to get proper exposure. You need to make some menu adjustment to make this work.
Yes, I have a number of lenses with aperture rings and I've used them on the K2S. I'm almost tempted to replace the solenoid myself. I've got the tools and it wouldn't be the first camera I've disassembled. Right now get the problem right when I turn it on..if I switch to live view and back...or turn it on and off a few times it goes away...so I'm functional to shoot...but I'm assuming the problem will get worse

That's how it is and with that low shuttercount a waste to use the sanding/filing method.
All has been explained, and yet... some love to go the cheap way.
Spending $250 on a camera repair for a camera I paid $330 for is just not worth it to me. If that were my only option, I'd replace the solenoid myself or just but another camera...and yes I'm cheap. I don't have $1500-$3000 to spend on photo equipment...that's why I shoot Pentax. I didn't see anyone complaining that this $100 repair didn't last (though I may have missed it) and I didn't see any guarantee that what an authorized service center does won't result in the same issue down the road either.

I had the aperture block problem with my K-S2 last summer, just after owning it for two years so just out of warranty . But when I contacted the Pentax repair partner here in Sweden they told me that Pentax had extended the warranty to three years for this specific issue, so I could just send it in and have it repaired for free! Warranties vary in different markets but this is a known issue, so always check what the terms are before doing anything else

Good to know...I'll check USA Pentax before I do anything.
Thanks

You can shoot any brand cheaply if you're willing to use their less expensive, less durable models. This is not exclusive to Pentax. As an aside, A SIGMA lens built for Pentax K mount generally costs more than the same model for CanIkOny models. I have spent a lot of $$$ on my Pentax kit (see below), but I started 17 years ago with a Pentax 10 and a 18-55mm kit lens for $340.00 used on eBay. A new K-1ii kit (w/28-105mm FA lens) will cost 2,300 (US). On the other hand, Pentax offers a K-70 with a kit lens for less than 700(US). Canon and Nikon have $400 offerings as well. Construction, features, durability and quality cost $$$. The K-S2 is an entry-level camera that has some nice features, but it's not designed or priced to last 200,000 shutter counts like its more expensive siblings (I own one & use it as a back-up--it has about 1700 shutter clicks with no issues so far).

I've said this several times here at the PF--a good photographer can use almost anything to produce great pictures (look at Brady's huge box cameras during the Civil War). But don't get angry when a value priced unit fails after 3 years. It wasn't designed for the long haul in the first place.....Buy a used K-3 with 15k shutter count for 400 (US) and it should last you for several years--or go to the Ebay graveyard and find a plethora of makes and models being dumped by point and shooters who want the next best thing or were disenfranchised by the size of the DSLR.

But simply saying you don't have $$$ so you shoot Pentax is a silly rationalization...hope you can resolve your issue with RICOH.

You did. It was mentioned a few times.

DIY with a white solenoid is worth it particular for a camera with that low shuttercount.

That is true indeed. Because they cannot change the powersupply.

As much as sanded solenoid plungers failed, did repairs fail by authorized service centers.
Usually after 1 year.

The difference is that with the same solenoid built in the only danger is failure if the solenoid again.
Sanding the solenoid can lead to further damage because the plunger will move with more play and when pulled outwards the already slight angle of it is enhanced.
Only the plunger of the white solenoid sits straigth.It is a final solution.

Saying cheaper was probably not the right word...I shoot Pentax because I get more for my bang for my buck. I bought an MX in the 80s because a Nikon Fm was $75 more and an Olympus om-1n was $50 more... Looking at Canon 20-24mp cameras run $500-$700 on eBay...I paid $330 for K2S with 600 clicks. Pound for pound Pentax is usually always a better deal. Btw, I still have that MX and it still works fine. Also...I'm not complaining if a 5 yr camera has issues...I just don't think putting 60-70% of the purchase price back into it is worth it...I'd more likely just buy a newer one. Would you spend $1700 to fix a $2300 camera? I'd just sell it for parts and be on my way.

Some clarification...authorized service center repairs also fail after about 1 year? Why is that? Are the replacing so solenoid with the same type (green)? If so then no repair service had a good solution? Only DIY is the long term solution? The $212 repair is no better than the $100 repair then...

TonyZoc:
No of course not....I think your response clarified it. Earlier in this thread I stated that if/when the K-S2 dies, I will toss it. I paid about $400 for It new with the 18-50mm WR retractible lens which I learned later is worth $300 new by itself, so I practically got the K-S2 body for free. Knowing it is already 4 years old means I bought it understanding that it would not be a long-term solution.

However, the K-S2 has several forward thinking ideas: 3" tillable screen, wifi that works, water resistance in a plastic carbon exterior that makes it lightweight, smaller size, etc. RICOH could build on this. Also, I like the way the 20mp sensor articulates images. However, the 'value' comes at a price in less durability and life. Most of us in this Forum expect your Pentax to "take a licking'" and keep on ticking'. Not so sure with the K-S2.

That's why I recently bought a leftover New In Box K-5ii with the 18-55mm SMC DA WR kit lens for $420.00. The K-5ii is rated for at least 100,000 clicks and has the all magnesium body, top LCD, low light ISO efficiency, etc. The IQ on paper doesn't seem to make the K-5ii as advanced as the K-S2, but the results in the field speak otherwise. Personally, I thought the K-5ii was the value of the year for me. That 16mp APS-c 'sweet spot' is so good to my method of photography that I'm convinced there is magic dust in that 5/50 series sensor (my K-50 was solid as well).

Anyway, I'm glad you're not giving up on Pentax per se...If I were you and you enjoy the K-S2, a used KP with 5,ooo clicks might be a winner for you as well.

I did understand it this way and totally agree. I think only AF-C can be critical for some, I never use it, so this would not bother me.

Then by all means... you have the advantage. It is straight forward, few hidden screws under the rubber, the K-S2 is the only Pentax body where you don't need to
take the screw out in the battery compartment, flash is a bit tricky to get to (for discharging it), it is on the other side, so battery out, let it stand for a week and don't
open the flash with the battery in.

Better not to go for the solenoid from the MZ50 or any other MZ, they are that tiny bit different, but any DSLR from K10D up to the K-r will do.

Don't take any solenoid from CD/DVD-Rom drives either, most have different impedance, some a different holding force, every solenoid was built to demand and specification. But all from the DLSRs I mentioned are guaranteed 100% identical and never failed.

I explained this HERE .

My experience with a lot of repaired (also sanded versions) K30/50/500/K-S1/K-S2's (I have repaired all of them) is exactly that:
DIY with the mentioned solenoid is the only 100% save long term solution.

Well, one shouldn't say 100% because any part can fail, even a white made in Japan solenoid. But they have never failed in any of the mentioned K-DSLR's nor was there ever reported a failure. When you have taken the green solenoid out of your K-S2 and then compare it just by pulling the plunger out of each several times...
I'd say everybody with some sensitivity will notice very clearly the difference.


So good luck! For you it should be peanuts.

Yes, most likely it will get worse. My K-30 starting exhibiting those symptoms in May 2018; by October 2018 it was consistently happening unless I was using half-charged AA batteries, so I switched it to a bag with several aperture-ring only lenses, and when I got a KP I moved it to the original collection of lenses. I try to use the K-30 at least once a month, and it still works fine with the aperture-ring lenses.

I received my K-S2 for a 30 year service award. It then sat in the box for about 18 months before I had time to mess with it. I retired at 33 years so thought I would take a photography class using the K-S2. The very first night I started getting Black images from the dreaded Aperture Block failure. Off it went to the repair shop, $212 for the repair and $28 for the shipping, so right around $240 all together. The camera comes back, the Aperture is working great and it makes really nice pictures.....Except the exposure info display in the eyepiece is black......no info. So I call the repair place again and off it goes back to them. I just got it back for the second time yesterday all seems fine now. I shot a few frames and the all look great. Hopefully it'll live a good long life now.
