My K30 is about to die... looking for compact quality-equivalent replacement

The DA35 sure is a great lens. I use it a lot on my K-30 as well. Currently on vacation in asia and I have a lot of night shots to process when I get back home.

The K-30 is a great camera. About 2 years ago, I lost mine in Hong Kong. Bought another refurb one on Ebay for $200. Same color too. Has not had any issue.
If mine failed, I would buy another, or maybe a K-50. Too many compromises were made in later Pentax cameras such as removal of in-body AA battery support. K-30 + eneloops forever.

My mom has been shooting with my old K200D. She has been complaining about indoor/night shots due to low ISO. I think it's time I buy a K-30 for her as well.

Thanks. Indeed, the Sigma looks like a better option. Not sure if I will go for it as I already own the Tamron 18-250. Now if we could get the Tamron 18-400 in a Pentax version...

What was that low price ? Reading this post one week later, it's hard to know if this is still a deal or not. Currently $454 as I type this, $105 more than the Sigma 18-250 . A lot to pay for those last 20mm.

Yes, piano and harpsichord. My audio is continuous and separately recorded.
Since I'm an amateur musician , it takes me quite a lot of takes until I get a good one.
Even though I never play any single piece >15 minutes, my workflow is such that I wouldn't want to stop the video recording after the end of each bad take. I might end up going to my remote control a few dozen or hundred times.
I prefer to have the video going indefinitely, just like the audio. I only stop the recording once I know I have a good take. I only stop the video with the remote, to mark the end of the good take.
The camcorder splits video in files of 2GB max each - so I look for the good take in any files that are <2GB . If I had to stop the recording for every bad take, I would have dozens or hundreds of video files of varied sizes, and would not know which ones are good or bad without reviewing all of them. That would be nightmarish as I don't want to go to the PC to save the file in the middle of my playing/recording session.
Sometimes I will do 2+ hours of recording at a time without stopping either the camera or the audio (even I take a bathroom break, I just leave the room and come back) . I don't want the tools to get in the way and it's much easier this way.
It especially becomes impossible to deal with if want to use more than one camera - that really multiplies the video files, if all the cameras cannot record continuously. I have not done that too much due to the fact that the camcorder is my only continuous camera. Everything else (Pentax, smartphone) has some sort of time limit in it which makes it impractical.
I have done it a little bit, but it's really hard to edit, even if I manage to get a decent take that completes within the shorter of all the cameras limits involved.
The HG21 camcorder has the ability to record without a limit; well up to the size of the max 32GB SDHC card.It splits into separate files every 2GB, but the software can handle it without dropped frames. I have actually hit the 32GB SDHC card limit in one session at a time before when I forgot to reformat the card at the beginning of my session.
For audio, I never run out of space as the PC that's recording it has many TB of disk space, and it could record for many days at a time. 32GB SDHC card means about 3 hours of HD in one shoot at 24 Mbps bit rate on my HG21 camcorder. I use a UHS-I card that's 95MB/s and can transfer the whole card to PC very quickly. But usually, I just transfer the most recent few files (most recent takes). Not always, sometimes I'm lucky enough to have more than 1 good take to review in 2 hours, so I do transfer the whole card ;)
The camcorder also has an internal 120GB HDD, but it would be extremely painful to transfer to PC over USB 2.0 speeds, much slower than the SD card. And I would have to take the camcorder off its tripod when I go to the PC. Much better to use the SD card.
Incidently, I just did the math on the GH5 - at the 400 Mbps rate, it will use 180GB/hour of video. 2 hour video would need a 512GB SDXC V60 card, which doesn't exist yet. 256GB V60 cards cost $200.

Since the GH5 has USB 3.1 and tethering, I wonder why Panasonic didn't allow recording video to PC directly via USB . That would solve the expensive card problem for me. I would just need some good USB 3.x repeating gear for the 50ft needed to my desktop in the next room (that's how long my 12 XLR snake cable is). Might be complicated firmware and software to write.
Or maybe just allow recording to external USB 3.x HDD / SSD, that's probably a lot simpler to implement - only firmware to write, no PC/Mac host software, and no need for USB 3 repeater.

Anyway, if I get the GH5, I can probably use a slower than 400 Mbit rate to begin with, until those large V60 cards come down in price. It can still do 4K/60 with my existing U3 cards at lower bit rate.

TLDR ;) Camera with no time limit allows me to record and publish stuff that I am not good enough to ever be able to play live in one take. Cameras with time limits get in the way.

I definitely need a bigger sensor than my HG21 for my videos which are mostly indoor .

Looks like these TZ/ZS compact cameras all have a 15 minute recording in 4K which makes them useless to me.

The Sony A6500 does seem to be the most competitive of those above three. Lower price, bigger sensor and longer 4K video recording time, than the XT2.
Still falls short of the GH5 in fps, color bit depth, recording bit rate, and recording time limit, though.

Yes, those are quite expensive cameras

I can barely afford one of those, certainly not 2.
IMO, Pentax has no excuse for the sorry state of video on their cameras.

If I had to choose a single camera today for both stills and video, I would probably choose a Sony A7S II with the hacked firmware that lifts the recording time limit.
That's a pricey camera with pricey lenses too. Don't really feel like ditching all my Pentax gear that is just fine for stills.

I don't have the requirement that my video camera should also be my still camera - they can be 2 different cameras. The GH5 would seem to make more sense as a dedicated video camera than all the others.
Sensor is 4/3, but that's still bigger than the sensor in my Canon HG21 camcorder which is my current go-to video camera.

Unfortunately, these Fuji cameras have only a 10 minute recording limit (!) in 4K, so they are automatically ruled out for me.

I have looked at the Sony A7S2/R2 . Those will record up to 30 min in 4K, I believe. But I have read about overheating too even on those.
I think I read somewhere that there was a firmware hack to remove the 30 min limit. Those have been on my watch list, but the price is still quite high at $2K body without a lens.
Still only 30 fps in 4K, 8 bit recording, 4:2:0, and lower bit rates than the GH5, though. But a sensor 4x as big.

GH5 is not only 4K, it's 4K/60, 4:2:2, with 10 bit color for video, with unlimited video clip recording length (not 30 minutes or 16 minutes !), and up to 400 Mbit/s bit rate recording to UHS-II cards. Really leaves any Pentax video in the dust. Only thing is that the 4/3 sensor is smaller in the GH5 than K-1 or even APS-C.

What I meant to say is, copy every feature from the GH5, and put a full-frame sensor. Doesn't have to be the specific model of sensor from the K-1.
Even if it was done with APS-C, I would still go for it, as I could reuse my DA lenses. Fat chance that Pentax is going to catch up now.

What originally led me to choose Pentax with the K200D (which didn't do any video) was in-body stabilization, and in-body AA battery support. The later feature has been abandoned in all recent Pentax bodies. The former is now in many competitors' bodies. My K-30 is probably my last Pentax camera. I bought it originally in 2012 when it came out. When I lost it on Jan 1 2016, I bought another (for $200 on ebay). Still love that model, except for video.
I can't justify $2K for a K-1 that is so far behind the competition in video, even if it gives me better stills. It will also cost me in convenience (no AA battery support).

No, I don't. I have a bunch of cameras, and I try to use them all, as much as possible. They all various limitations. One limitation common to almost all of them is the 30 min video recording limit.
Well, 16 min on my K-30, 5 min on my Note 4 in UHD. The only video camera I have that runs more than 30 mins is my old Canon HG21 camcorder. Which is still pretty good, but not 4K. And the picture quality is not close to a DSLR.

If I get a GH5 , I expect to use it mostly for video. Not sure how it will do for stills, but I expect it to be inferior to my Pentax K-30, especially in low light.

I do own a superzoom for my K-30 (Tamron 18-250). I use it sometimes . I have many primes too that are very light. But time and convenience to change lenses can be an issue.

I don't own any single camera that costs $2K, though. The most expensive camera I ever bought so far was that Canon HG21 that was $1000 in its days. Next is probably my Note 4 (smartphone) and K-30 at $800 each. I bought my K-30 when it first came out so paid a high price. When it was lost in Hong Kong, I bought another on ebay for $200 :)

The K-1 costs $2K. So does the GH5. It's hard for me to justify a single $2K camera, let alone two of them.

---------- Post added 09-29-17 at 08:16 PM ----------

Can you cite some of them ?
I have wanted >30 min recording for a long time. Almost none of them have this, except the GH5.
GH5 also has 4K/60p, which almost no one else has, and I really want to use that as well.
Lastly, >8 bit color should be very useful for my indoor video shoots to make lighting adjustment in post. With 8 bit video, it's just not possible.

Most of the lenses I own are DA lenses with no aperture lever, and wouldn't be usable on Panasonic AFAIK, unfortunately. At least, I couldn't find an adapter that would work for this case. I believe it would need to have aperture lever in the adapter itself, or electronic chip to control through the camera.

Thanks for the pointers to GX80/GX85, I will review them.

That's a lot of money to spend, though, and you have to carry twice the bodies and lenses.

I think for me the K-30 is "good enough" for photos. Hard to justify a new $2000 body and all new lenses for the incremental improvements I would get with a K-1.

Unfortunately, the K-30 is not anywhere close for video. My next camera is very likely going to be a GH5 for the video.

In terms of stills, I'll probably keep shooting with the K-30 . K-30 is better in low light than GH5. That's somewhat expected due to the larger APS-C sensor vs MFT.

Pentax K-30 : Tests and Reviews - DxOMark
Panasonic Lumix DC-GH5 : Tests and Reviews - DxOMark

Of course, K-1 tops them both by a mile for stills.
Pentax K-1 : Tests and Reviews - DxOMark

IMO, Pentax needs to make a camera like the GH5, but with their K-1 FF sensor.
Or even an APS-C sensor, still going to be better than MFT.

One of the things that impresses me the most in the GH5 is unlimited video recording, vs 16 minutes on the Pentax in HD . And 30 minutes on most other cameras due to European tax.
Panasonic really has a hit on their hands with the GH5.

ISO - what do you REALLY use?

Views: 4,306
Out of about 12,000 saved shots so far, about 10% of my shots are at ISO 6400 on my K-30 . 25% for ISO >= 3200 .
I usually am on auto-ISO 100-6400 .

I find 6400 to be very usable. Have very few shots above that (<100). I have a grand total of 0 usable shots at 25600 , just tests.
Maybe 5 usable shots at 12800 . A dozen or so at 8000 .

It's no wonder I never set the camera >6400 anymore.

Looks like the main reason to get the Canon would be the weight 453g vs 703g for the KP.
Also it does 60p video vs only 60i for Pentax.
Otherwise the KP is better in every way.

Looks like they are not in the same price range, also.

Running K-50 firmware on K-30

Thanks for the firmware. I applied it my K-30 and it worked fine.

I was hoping for some video improvements, but alas, contrary to what was quoted earlier , video recording does not stop at "4GB or 25 minutes, whichever comes first". In the highest quality, I'm limited to 16min38s.
The resulting MOV file is 2.6GB. So, neither the 25 minutes nor 4GB were hit. The countdown started from 16min39s right from pressing the shutter in video mode
Guess this is nothing new, just broken video as usual for Pentax.

I have yet to shoot stills. Need to restore my settings into the camera now besides date/time.

Looks better, but you are at F4.0 when you could be at F2.8 at 50mm which would give you more light.

I would use P mode and both dials - adjust F to 2.8 , and shutter speed as needed.

Given the problems with focus with your DAL , I wonder if there is an issue with focusing on your camera body.

Can you focus and take shots of something that's not moving, still keeping the same high shutter speed, and see if it's in focus ?

I would definitely shoot RAW as well, and denoise in post. I get pretty good results up to ISO 6400 in general, better than what you are getting.

The 550D is the T2i . 600D is T3i.

Agree about dynamic range, but ML gets you auto restart (with a break, unfortunately) and you can't get that on any Pentax K. You can get much higher bit rate on Canon with ML also.
Wish those cameras did >8 bit video recording, then there wouldn't be as many problems in grading.

Not sure - I used Magic Lantern on a T3i - it was great, but did not get around the 30 min recording limit, unfortuntely.

I think 16K video would be insane given that most people barely have a 2K monitor.
An 8K monitor costs $5K ! I haven't even sprung for 4K monitor myself yet - I'm still looking for suitable KVM options for 4K, have not found one, and that is holding me from moving beyond 2560x1600 - my HP LP3065 have a built-in video switch- 3xDL DVI inputs. The newer monitors don't have anything comparable.

How long were your takes ? I was planning on using the firmware hack that lets you record video indefinitely on the A7 series, and do >30 min takes.

I think Nikon is doing 4K FF too on some of their bodies, but very limited in take length, and overheat reports as well.

For me, the video is mostly indoor and tripod-based. Full frame really helps indoor. And I don't mind the lack of weathersealing in this situation.
A7 series are reported to overheat for long takes, though ...

There are a lot of horror stories about Sony support as well, unfortunately, even on their expensive cameras. It's really shocking.
