Highest acceptable ISO

It all depends on what you are doing.

I have a K1 mk II (upgraded from mk 1) and shoot a lot of street images - day and night, and have TAv set to 25600 maximum ISO for the night shots, and maximum 1600 in Av mode for daytime.
Yes there is noise at 25600, but for what I'm doing (including B&W conversion in Silver Efex) the noise is acceptable - I'm after an impression of the life around me. The K1 mk 1 had much more noise at that ISO.

Here is one at 16000 ISO:
Adults only

And another at 25600 ISO
Bar keep

To me these are acceptable and capture the moment - better than any smart phone BTW.

If I'm shooting portraits or macro or landscape etc I'll limit my ISO to 1600 or maybe 3200 with people - I can accept the level of noise in those images. It's not a lot different from film days - low ISO for the detail, push process and get plenty of grain with high ISO film for reportage or texture or to get the shot.

You will have to look at the images you create and find your level of acceptance. There is no hard and fast rule IMHO ;)

Thank you Andrea - you've done a great job! I tried it out whilst stuck in an airport recently to see how the focus points work and was impressed
Here is an example - focusing on the main subjects ear :) using an FA135mm lens

I did have a few issues with the application freezing which seemed to be related to WiFi disconnects. Not a big problem given this will not be my main use - my street work is all hand held walk about mainly

Once again - thanks.

K1 to K1 Mark II or not II

I've had my K1-ii back for just over a week and feel that overall the AF is faster and more decisive.
My style is mainly street work these days, and do a bit of post processing in Nik Silver Efex, but pixel peeping at the images I find they are cleaner and I need to adjust luminance/noise far less.

Detail is no worse than the K1 in my opinion.

I tried out the dynamic pixel shift when I got it back - and had a look at some comparison images at ISO 3200 and 25600 (had to do that in Raw Therapee - LR CC still has no support!) which were very impressive.
I shoot a lot of images up to ISO 20000 so I'll be doing more testing - but so far all good.

If you want to see what I've done so far - in B&W and Nik Silver Efex -
here are a few images on Flickr

In my opinion its worth the upgrade

The official K-1 to K-1 Mark II Upgrade Feedback Thread

I've had a positive experience with my upgrade through CR Kennedy in Australia.

I took the K1 mk 1 in on 31-Aug-2018 (Friday) about lunch time, got the K1 mk II back on 17-Sep-2018 (Monday) at ~9:00 am. Given there it was a weekend drop off, it had to go to Melbourne from Adelaide etc that isn't too bad.

I would have liked it at the end of last week when I was in Geraldton for some dusk/night shots but c'est la vie. My K5 was acceptable though lacking the refinement of the K1.

So I now have my camera again with it's SR logo in a zip lock back, the II logo in it's place, a new K1 II CE decal on the bottom, and the biggest surprise - all my settings intact :cool:. My understanding is they would be reset to factory default and I'd need to re-enter them, but everything was as I'd left it - even my copyright details. I only had to set date and time (my city was as configured). Does that mean they download it and then flash it back?

Next job - test it out and see how it performs.

Have to change my sig while some time too

I'm using my K5 whilst my K1 is being upgrade to the mark II and have to say I'm missing the K1. The K5 is good - but lacks the refinement of the K1.
I've noticed the hesitant AF (and fewer AF points), the mass, the LCD viewfinder resolution, the button placement as big differences.

I'm looking forward to the upgrade - after hesitating with the many naysayers.

Enjoy your new K1-II - hope to join you in that world soon ;)

It gilds the K1 nicely - AF update, ISO improvement etc - and makes that main board update appealing (particularly those of us using the low light capability)

Thanks for sharing

How high do you push the ISO on your K1?
Posted By MoiVous

I've been surprised how good the images are at high ISO - only tried up to 20000 so far.

Here are a few of examples - processed in Lightroom with a little luminance reduction (I take the Luminance slider to about 30) and some minor cropping. The grain looks quite reasonable before that. I took a test shot at 204800 once - not pretty, but usable as a record shot

These are at ISO 10000:

Alley walk

Croft Lane - drain

These are at ISO 20000 - the first ones are from a music gig with LED lights

Evan and the Hammond!

Erica and friend

Erica and the dancers

And this one was in almost total darkness through a hole in the hoarding at a demolition site - not as good as the music gigs but it was a first attempt

So you can see that it really is very usable. I haven't tried above 20000 yet - that might be a series that needs proper testing with one subject and lots of shots.

Good luck with it

WARNING - K1 in Pain - Not for the fainted heart !
Posted By MoiVous
Replies: 31

I feel your pain! :( And with the cost of K1 and that lens it's more than an ouch moment!

My K5 and Sigma 28-70mm had a fall like that a few years ago - getting off a plane the camera bag slipped off my shoulder and fell about 1 metre onto the stairs. It bent the AF screw & lens mount in the camera, the AF helicoid (it's a rail and stud arrangement) on the lens, the aperture coupling and the lens bayonet (the combo weighs about 2kg).

The camera needed some love from Pentax - and came back no worse for wear (and no cost!). The lens needed serious attention from my camera repair tech. That got fixed. The lens had the helicoid skip off it's rail again recently - but there were no drops I was aware of.

Insurance wouldn't cover it - the cost of repair was less than the insurance excess.

The camera repair tech suggested that I ensure the lens is carried with the focus at infinity and no zoom to keep the helicoid at minimum

Moral of story - don't drop it! Heavy camera gear and gravity don't mix well

Hope you and your K1 are back together soon. I think a little TLC from the Pentax techs will sort it

I can second the Sigma 100-300 f4 - and yes it wasn't cheap. Handles and balances well on the K-1. AF is fast for a screw drive too - better than on my K5

Here are a couple of images from it with my K-1 taken a couple of weeks ago at Chinese New Year

I've also got the Sigma 120-400mm. That works reasonably well too, but I think the Sigma 100-300 balances better.

Ok - so everyone has said how much they love this camera.

I got to seriously use it last week wandering around a food market then going to a live music gig with LED lights.
What's more, I used my old Sigma 28-70mm f2.8 DF only. So not a current generation lens, and screw drive, and it's been in the wars (dropped it and had it fixed a couple of years ago)
  1. AF was snappy and mostly spot on (some errors when I was in AF33 vs AF9 - that is just me learning I suspect)

  2. low light was no challenge to the AF or the exposure - no more than 1/2 a stop off most of the time. I used it the night before in near total darkness at my camera club and it didn't even struggle!

  3. that change to FF from APS-C has made the lens much more usable as a walk around - wide to short tele, with great DOF change - got to get used to f2.8 really being shallow!

  4. Noise at high ISO is no drama (I shot up to 6400 ISO at the music gig, and 12800 at the camera club) - it really is easy to deal with in Lightroom. And the pixel size is so small you don't really see it

I can see why everyone is in raptures - it is a beast (and the pair together are a heavy combo BTW)

Here are some shots from those two shoots:

AF infinity focus with DA70mm limited on K1

I have a nice shiny new K1 and am loving it - fast, intuitive (coming from a K5), buttons good, lots of useful options.

However, I've noticed an odd behavior with the DA70mm limited (both in FF and Crop mode) - for normal focus within a few metres its fine (using either 33 or 9 point focus). But at infinity or near infinity it won't lock on. Plays up with spot focus too at infinity.

It works ok with my FF lenses (FA50mm f1.4, Sigma 28-70mm f2.8, Tamron 90mm f2.8, ) ok. Seems ok with my DA15mm limited

Does anyone else have this experience?

The word from the bricks and mortar stores in Adelaide (and I think I know the one Kevin means with the binoculars etc) is that CRK don't seem interested in working with them, so they don't stock Pentax.
Looks like they are trying to push all Pentax dSLR purchasers to their website and shut all others out. They also suggested that Canikon are almost as unresponsive. Seems that holding a camera in your hand before you buy is a thing of the past.

Sigma 10-20/4-5,6 EX DC ?
Posted By MoiVous

I've had this lens since 2008 and love it, although sometimes I'd like a little more reach. It certainly seems sharp enough to me - and I've printed some 16x20" images from it with no problems at all.

One thing I like to do is exploits hyperfocal distance - makes for some dramatic shots.

You need to watch any filters you attach - at the 10mm end they need to have very thin mounts to avoid vignetting.

There are plenty of opinions about it in the lens review database, and you can see what it can do on Flickr (Flickr: The Sigma 10-20mm Pool) and other sites

Good luck with your research

That's not a lot of storage in real terms - I have a NAS (2 x 1TB mirror RAID) that my images and music live on. No where near full - even with a bunch of software/document/system backups as well. From memory I've used about 35% for images.

Think about it - 1TB is 1048576 megabytes or about 41943 image files (if 25MB). You'd have to shoot about 110 images per day every day for a whole year to fill that up. That's a lot of images. Do you shoot that much?

If you use the shot gun approach to shooting that could be a problem. But HDD prices have dropped again, and you can build a 2TB (2 x 2TB drives) mirrored RAID NAS for under $400 and that gives you 83000 images. Or go the whole hog and build a 12TB system. Cheap insurance for an amateur. Pros will need more storage of course.

As for RAW shooting, I've been shooting RAW since my K200D purchase in September 2008 - and have most of them (except the true duds). With my K5 I use a bit more storage - but not that much.

If you use an application like Lightroom you can roll back to the original image with no loss of data. With new process functions in each version you can even go back and tweak images further.

Just my two bits......

Lens mount wobble (rotation) on K5

I just bought a Sigma 120-400mm lens, and noticed that when the lens is mounted the lens body rotates a little on my K5 - as if the mount was loose.

Not sure if this is the lens or the camera. Tried my Sigma 28-70mm DF (also heavy, but not like the 120-400) as well and I can feel a similar thing, but not as obvious. I haven't tried any other lenses yet. Maybe its because the 120-400 is such a heavy large diameter lens.

My old Canon T70 used to do something like this until I tightened the screws holding the bayonet on the camera body.
Could this be the same sort of problem? Has anyone else experience this? Am I being paranoid? :(

This has been discussed many times before - and the results are variable. You can see people have used all sorts of lenses. The downside is variations in quality.

Have a look at this thread:

As an aside (and off topic to a certain extent) I've managed to mount a Canon FD auto bellows to my K200D with a K to Tmount adapter + Tmount to FD adapter. Works ok - just need better glass in front. I'm thinking of microscope objectives or enlarger lenses.
