The aperture block in my K3 failed after about a month last summer after being repaired by Precision. The current one has been in there since September, and seems OK since.

Thinking of Making a switch away from Pentax. is it right or just gear envy?

Just chiming in on the D750, my mom shoots Nikon, and recently bought a D750, grip+24-120 f/4 lens with some accessories from B&H over the holidays for a hair under $2k. That would probably just get me a K1 and grip. (not that I could afford either, but ;) :hmm: )

Pentax is getting really long in the tooth with respect to AF (for me to upgrade from my K3, I'd really want D500 level performance, don't care as much about FF TBH) and lens selection, as I'm also really jonesing for some of the updated Sigma and Tamron lenses, and Tamron is good enough for Pentax to re-brand for FF.

Pentax is probably getting better with PLM lenses over DC and SDM, but it's been a on-going thing, they improve, but then Sony/Nikon/Panny, etc leap frog way ahead.

Sounds too smart, probably will release another Q or 360 camera.

However with mirrorless, I would rather see them do a Sony and design something fresh from the ground up, don't see why they could do an adapter that allows some backwards compatibility, IIRC both Sony and Canon can do it. They would also need an AF for mirrorless that isn't trash, my K01 or K3 in live mode is just...:fedup:

Wouldn't mind a cheaper FF, as I can't afford a K1, and it would take an awesome APS-C dSLR (like D500 level AF) to get me to upgrade from my K3.

There may be a ROM/FW preventing them from updating the K5 series, but sometimes forward compatibility can't be planned for.

My 16-85 won't AF on my K100D. At some point, technology has to move forward. Ex. screwdrive is a nice relic, but it literally sounds terrible, slow, and I'd just rather not anymore, the difference between the 16-85 and nifty 50 is just extraordinary. IMO, Pentax shouldn't be using the SDM designation on the new lenses either, DC and PLM gave a me a written notice that I have something different than the 16-50 motor for example.

I've also had the aperture block replaced twice in my K3, first time was my fault, but mechanical linkages are prone to physical damage, not just electrical failure. If Pentax can move towards a Canon-like all electrical aperture/focusing system, I'm down with that.

Pentax Value

For me, Pentax's value is in their bodies, with features that only found on more expensive prosumer Canon and Nikon bodies.

WR and SR for any lens is nice. However complaining about the AF or selection of lenses is probably a broken record at this point. I used to rant about the AF on my K20 all the time here, then I bought a K3 a couple years ago, and it's night and day. If Tamron/Sigma came out with their 150-600 in K mount, I'd probably buy that, and be done with LBA and desired focal lengths. Pentax is on the right path with DC and PLM (just pretend SDM wasn't a thing), and they can keep improving AF speeds bit by bit.

Drove down to Bannack state park yesterday (it's an old mining ghost town, similar to Bodie CA, but not as hard to get to). The mix of fall colors, overcast shade, circular polarizer made PP in Lightroom almost HDR like, but I don't hate the effect, and the old wood has a strong contrast as well. Winter is coming way too soon for my liking in western Montana though, as it was snowing at higher elevations. First time I've used my Sigma in probably over a year, I forgot how much I like super wides.

I got my K3 back last week, Precision did fix it this time, replaced the aperture assembly again, took it up to the National Bison Range on Saturday, and it worked well.

It took them about a week to fix it (and a week in transit) but at this point, I'd rather not have to get it fixed again, which is poor QA/QC - Precision can only put in the parts given them, but Precision has to do the correct repair in the first place.

My first K3 repair seemed fine - replaced a broken aperture pin (the tab inside the mount), in which they replaced the whole aperture motor and mount. Repair took all of June, mostly waiting for parts.

Seemed fine for a couple weeks, and took great pics, but then it could no longer control the aperture - the camera meters, but the aperture is stuck wide open. Thought that the motor just failed, and sent the camera back for a replacement. I told them of that issue n the new invoice when I sent the camera back at the beginning of this month.

Got the camera back today, and it's having the same issue before I sent it back, so back again it will go, but I guess I will have to attach a old18-55 so that they will actually check lens function, rather than just electrical functionality...:mad:

Oh well, guess I won't have my camera in time for a trip to Yellowstone in about 3 weeks.

Need help diagnosing a wonky K3

Recently got my K3 back from Precision (broken inner aperture lever, some damage to mount due to a tumble off a hotel bed with a Bigma attached). Sent the camera out at the beginning of June, received it back end of the month - they had to wait on parts.

Anyhow, they replaced the aperture motor assembly and mount, and everything seemed fine up until this weekend, although in truth, I've only used it like a handful of times since I got it back. Saturday seemed fine, took some pictures on Rainy Lake, but yesterday at Seeley Lake, the camera couldn't change aperture (stuck wide open) and the mode dial is being a bit flaky, most modes are now showing up as manual, even when set to a different setting (Av, Sv, etc), but sometimes it's correct. The camera is trying to meter at the set aperture, so everything is overexposed, and I can hear the lever trying to do something, but the DoF preview does nothing.

Since the drop and return, I've babied it, and can't think of any moisture or drops that could've fouled it up, always in a camera bag.

I don't know what to do with it, contacted Precision, as I'm hoping they have an idea and/or warranty on service repairs. Part of me thinks that if something is going to fail (the new motor), it's going to do it fairly soon, just wondering if stuck fine open is a common symptom of that type of failure

I had a good experience.

Just got my K3 back today, due to a case of rolling off a hotel bed back in March, with a Bigma attached, it broke the inner aperture lever and some damage to the mount. Fixed both of those issues, and works fine with Bigma and 16-85 (only lenses I've tried so far). They also updated it to the v1.30 FW and did a cleaning and calibration.

Took about a month to the day, most of which was spent waiting on parts. Spendy - $312.50, but cheaper than a new K3II or KP

I realize that I'm replying to a 2 month+ old thread, but Chrome was showing their order form as secure and using https, but just to be on the safer side, I used a Bank of America Shopsafe number when I had to fill out the form to get my K3 sent in for repair yesterday.

Just hope they have decent turnaround time, my only experience has been with Tamron, and they were good IMO.

The old version of the Bigma, AF racks a bit, but I felt KEH had a good price for it, and I couldn't believe that it was a BGN rating when I got it (glass looks fine, and hardly any marks on the barrel).

Big and heavy though, now I'll have to invest in a better tripod.

why hasn't anyone bought any Limited Lenses through the Massdrop deal that was posted

I've used Massdrop for an audio amp, they're legit.

Not sure how big of a deal you really get, I probably only saved about $20, some of the bigger deals are on limited runs of boutique headphones, similar models to German or Austrian made Sennheiser or AKG cans, respectively, but made in China. There you're trading location and manufacturing costs for similar headphone types. So instead of getting Sennheiser HD 650s sold through Amazon for $375, you'll get Sennheiser HD 6xx, but sold through Massdrop for $200. Essentially, the same cans, but where they're made is different.

I still generally prefer B&H, Adorama, or KEH, but then again I haven't seen a big physical store in ages, especially one that carries Pentax gear, I pretty much have to buy blind and online to an extent.

I own both lenses, and I prefer the Pentax.

The DC motor and WR are great, and it's no slouch in sharpness either. The extra reach is a bonus too.

The actual Tamron comes with a 6 year warranty though, and their service has been good in my experience (NY state, 3 day turnaround time) to fix my 70-200.

Not complaining about the price, since it is just a rebadged Tamron, but just a 1 year warranty on that same lens, just a different mount? Hmmm. Knock on wood, I've really been impressed with my 16-85, but Pentax doesn't have a great track record with QA/QC.

Tamron 28-75: Another Lens Repair Journey

While I don't have the 28-75, I have a 70-200 that I bought used off of craigslist, and while it was decently OK, it was decentered on the right lower corner of the frame - the joys of buying used.

Eventually, I got enough money put aside to have it sent to their NY repair shop - cost about $225, not including shipping, and they fixed it in about 3 days. Part of the service included an CLA as well.

So far so good, and the lens is sharp across the frame now.

It rained last night at the Grizzlies game, and I got unhelpful advice from a C&N user behind me to boot, but my K3+16-85 did well (first time I've got to use my new combo in the rain).

I'm sure there are limits to how 'wet' I can get it, but a decent rain seemed fine.

The smoke ATM is killing contrast (and my lungs), but this is becoming my go-to lens. And to my genuine surprise, the K3 is a decent camera for sports. They really should've cancelled the game yesterday though, due to the awful air conditions.

The last picture shows what rain clouds look like in comparison, both that and the picture above it show Mt. Jumbo (the one with the L).

I remember going into Camera Mart, circa 2007/08, and they still had a K110D sitting on the shelf.

It's actually a really nice store, just not a lot to pick from if you don't shoot with C&N or Sony (which I understand too).

Mine came Tuesday from Adorama, so far so good, really sharp lens, and I like the contrast. The silent DC motor is almost a revelation compared to screwdrive.

I have noticed that my mic port cover likes to pop out though, while I understand that with a sealed lens, that air has to go somewhere, but I'm somewhat concerned about the cover coming loose, and moisture getting in. Took this tonight, downtown along the Clark Fork.

What are the lenses that work best with K3
Posted By guinnessman
Replies: 25

My primary lenses are the Sigma 10-20, Tamron 17-50, and Tamron 70-200, although TBH, I never liked the 70-200 all that much on my K20 (slow AF and it was decentered, I bought it used, but I don't understand who I bought it from never noticed it). I also think it might of had some BF/FF issues too. Maybe the adage, you get what you pay for is true.

K3 does have faster AF, and I just got the 70-200 repaired through Tamron, which so far seems to have corrected the decentering. I've read that the 17-50 has similar QC issues, but mine has been tack sharp (bought used through KEH), and the Sigma is generally my favorite lens. I will probably get the Pentax 18-135 or pony up for the 16-85, as I don't have any WR lenses ATM.

How to get better results w/Tamron SP AF70-200 f/2.8

I'm responding late, but here's my $0.02.

Check to see if the lens isn't decentered - I bought mine used off of CL a couple years ago when I was still living near Fresno, and while I could get acceptable shots with my K20D at Grizzlies games, taking some pictures of bison last week north of here showed that my new K3 didn't magically fix things. The bottom right of the frame is always blurrier, relative to the rest of the scene. Judicious cropping can fix it sometimes, but sometimes I want the right side of the frame...

Today I mailed it out to Tamron in NY to get fixed. Speaking of Tamron, I know decentering is a common complaint of the Tamron 17-50, which I also own, but my copy seems fine.

It's a good lens otherwise, but you do have to work around it's AF as others have mentioned. I get my best shots above 1/500 or so, and stepped down a bit. At 2.8 and 200 mm, it can sometimes really have trouble getting the right focus, and in a similar vein, it has issues when action suddenly moves towards you.

K-3II to be announced soon

That's seems like a specious argument...how would I know that what Pentax was doing a decade ago would end up more expensive and less improvements to AF compared to others? I know other people do own multiple systems, but I would probably take a bath on selling a system that most people wouldn't want, unless you're into shooting mostly static things. Nearly 10 years ago, I was perfectly happy to get into the dSLR arena with a K100D to do just landscapes, and it was a massive upgrade over my P&S cameras. Now I really like shooting baseball too. Ex, some people really care about video, but it's not a major requirement for me, but there are some systems built around that.

If I knew then what I know, I probably wouldn't have considered Pentax, as it doesn't fit all my shooting styles now, but it's not like the competition only considers one type of shooter either, if people want to shoot landscapes and fast action, they work on ways to improve the lens focusing and AF detection because things change. Pentax is gimped by the screwdrive and SDM IMO, although the bodies are competitively priced and have some killer features.

I'm expecting my upcoming K3 to be quite a bit better in AF, compared to my K20, but I just know some things will be more difficult than even with my refurb Nikon J1.

I'm not trying to negative, just completely honest in my assessment. It could just be the segment that Pentax markets to as well, more purposed than the rest.
