K-1 II upgrade program extended in Canada due to unexpectedly high demand

No specific knowledge, but the package would include seals and any assembly bits and pieces required for the job. And the main board. This would have been a production run at some factory somewhere. They didn't do enough, and they are no doubt arranging

What I find heartening is that the overwhelming bad reviews are being ignored. Nothing I have read about the upgrade matches my experience. I simply will not pay the slightest bit of attention to those people; they are untrustworthy.

You can run darktable with these presets like this:

darktable --noiseprofiles path/to/presets.json

I would like to get some feedback on the presets. Some of the iso's have a few to select from, some more aggressive than others.

I'd encourage anyone who is even the slightest bit dissatisfied with the K1 autofocus to update. It is a difference in kind. The other changes are nice, and the noise handling is welcome, changing something that is pretty amazing into a bit better.

If you are using Darktable with the K1 Mark II here is a noise profile. Take a look and see if it works. There are multiple profiles for lower isos, I'm looking for something that doesn't over smooth.

EDIT: Oops, having trouble uploading it. Will update.

EDIT again. The presets.json is available

K-3ii to D500... Is this the right move?

I'm not sure if this is a concern, but do Canon crop sensors deal with low light as well as the D500, or the K3/D7200?

If I read the requirements, the longest and sharpest lens available is going to get the best results.

The 300 PF is indeed light and compact, very nice. The autofocus performance decreases with TCs attached though. I'm not certain if that is what Ian is referring to, a slight degradation from excellence, or if it is a problem.

Another little thing; my friend with the D500 had shot the D7200, the D7100, D7000, etc. Nikon guy for years. It took him the better part of a year to learn how to use the D500 to it's potential. His setup is the D500, the 300 f4 PF, and a collection of extenders. A very light capable package. A second friend just got a D500. Long experience with film, and had a D5000 for quite a few years. He got the 200-500, got some good results. He isn't going to haul a tripod around and found the whole setup heavy. He just got the Sigma long zoom, 150-600? not sure, not the field model. Considerably lighter, and we are going out on Wednesday and I will hear his mutters and grumbles as he figures out how to use it to advantage.

Another friend has the Canon high end field apsc body with the 200-400 ? He is getting shots that are amazing; the focus is very quick and accurate. That too is a nice light package, very capable.

And I get shots that neither of them get. And believe me I appreciate the fine points of the equipment I'm using. I judge my equipment over a full year cycle. Low light is a massive part of my shooting experience, it becomes the important factor.

You know where and what you shoot, and also know that wildlife is 7/8 technique.

Frankly, I just want one of each. I could go to the equipment room, my technician would hand me a cleaned and adjusted body and lens that I think would be good for the day. My Sherpa would carry it to location, and I would get amazing shots. A couple scouts would tell me where the action is.

In my dreams.

Pretty well anything can get good results. Have fun.

Does the K-3II slow down continuous shots in AFC when the af button is pressed? The K1 Mark II doesn't.

Either in crop or full frame.

I shoot the K1 Mark II (for a couple weeks, K1 for two years) with the 150-450. I used my K3 for the two weeks when it was away. What I found annoying with the K3 was the usable ISO ceiling being too low. And what happened to continuous focus recycle rate. I regularly shoot iso 3200, and with the K1 got good results up to 6400 in some light conditions. With Mark II I set the ceiling to 12800. What that means is that I rarely shoot at 1/400 or lower in low light. If you shoot the K3 you know how often you have to do that. The low light capabilities of the K1 is absolutely amazing. I can take shots of things I can't see and identify what I'm looking at. Wildlife shooting is about low light conditions, even on bright days, the blighters seem to want to hide in the dark corners. The K1 opens up shooting opportunities.

Focus with the 150-450 is excellent with the Mark II. Decisive and accurate. Tracking is very good. The K1 would show focus in the viewfinder but the shot wasn't. Mark II gives you what the viewfinder shows. This is the best focus experience I have ever had with Pentax, since the K5.

I use crop mode in situations when I want a faster continuous shooting rate, or the subject is far away and I will be cropping anyways.

It is a bit heavier and larger, the files are larger.

Any body lens combination will have advantages and disadvantages.

I have two K3's that I bought shortly after they were released. I rarely use them because the K1 is much superior in every way for my shooting.

Indeed. I'm taking shots at dusk and dawn, and in good light the K1 is amazing. As I said, the AF in Mark II is substantially better. I have no reason to look at anything else.

It is better than the K3II and the K1. The D500 is very good.

This with the 150-450.

I agree with reh321. The D500 is a very capable body, but not magical. My friends have spent half an hour sorting out some configuration detail. I think it is better in low light than the K3, not sure. The fast refresh rate is nice in some circumstances. But the K3 is very capable as well. I'm very serious when I say that I get shots they don't. They get shots I don't. Most of it is technique.

I'd seriously look at the K1 MII. At cropped rate you get almost the refresh rate of the K3 and in both modes there is no slowdown in AFC holding the button down. Low light capabilities will transform your shooting, and get you far more shots you couldn't get than a bit better AF.

This is with the K1 Mark II. A prairie falcon, it flew directly at me. I managed to get three shots, one was in focus, the others were out of focus because it was flying overhead and I couldn't keep it in the focus points. A fast bird. I wouldn't have gotten this shot with my K3, and wouldn't have even bothered with the K1. The first one is substantially cropped.

The D500 is a very capable body. There are good lenses available.

As for birds in flight, the K1 Mark 2 autofocus is much better and I get birds in flight shots regularly. I didn't bother taking them with the K1. And got the odd one with the K3. The low light capability of the D500 is very good, the K1 a bit better.

I have friends with the D500 and they get good results. I get good results with what I have. I get shots they miss or can't, and visa versa. I should mention that they get 3x the bad shots and good shots both.

The K1 mark 2 capability bodes well for the next apsc body from Pentax.

My new KP overexposes nearly every short

Look at page 104 of the manual, Optical Preview. Page 102 you can set it to the button on the shutter. Set the aperture to F8 or higher, look through the viewfinder at a light of some kind, then switch the preview. The image in the viewfinder should darken.

This is to verify that the lens is being stopped down when you take the shot. The lens is wide open when you compose and focus, and stops down when you expose. If it isn't working it definitely will be overexposed.

The photos in your post don't have very dark areas that spot metering would mess up.

What exposure mode? Spot can be tricky.

Is the lens stopped down? It could be that it isn't operating. Try the preview to see it if stops down as expected.

Ah. I see that Paul C Buff has a couple that work like that. The Godox one seems to have a very short duration at high power.

Flash Duration Analysis with the Sekonic L858D-U ? The Broketographers

has some timings.

Thanks for the information. Knowing what to look for really helps.

Having a dish that aims the light will increase the light as well.

Thanks. That makes sense. You can then figure where on that curve the light emission drops below the level which exposes.

I'm trying to freeze movement at about 1/4000. Speedlights do that at about 1/4 or 1/8 power. I had 5 of them firing at once which worked ok but was rather complicated to set up. I would like to replace that with a battery powered light, or two.

Now to figure out how watts output translates into guide numbers or some idea of exposure.

If you go to page 32 of these specs it lists the flash durations and power output.

What does t0.1 and t0.5 mean?

And what does watt output represent? or how is it translated into Guide number?

Thanks

If someone bought my gear and I could use the money for anything? I would get Pentax because for the money I get more.

K1 Mark II. For the money what would compare? The D850? For the price I have the K1 and the 150-450 lens.

43mm Limited. Small, built like a jewel, and very nice IQ.
150-450? Nice, very sharp, the comparable lenses are 50 mm shorter.
35mm Limited. 12-24mm. Probably alternatives.
300 f4. Lots of nice lenses from all manufacturers.
Sigma 500 f4.5. I got it used, very nice IQ. Any mount would work.
70mm Sigma, 90mm Tamron, FA100. Lots of macro choices everywhere.

For the money I don't see how I would get even what I have, let alone more. A D500 is nice, I have friends who have that and get nice results, but the K1 does better in low light. And both have had situations where some setting took half an hour to sort out. A bit ridiculous if you ask me.

Here are a bunch of high iso images, no noise reduction applied. I suspect I will see a few situations where the IQ is degraded, just as I've seen moire in feathers the odd time, a handful of shots over thousands. As you say, the low light capabilities open shooting opportunities. Better focus gets more usable shots. In going through the shots I've taken since the upgrade I'm blown away how many very good ones are at iso 3200. The K1 is excellent at that ISO, as is the Mark II. The K3 in some light and color situations gives good results but rarely.

The shots with the sparrow would have been mud with the K3, and I'm not sure with the K1. There were lighting situations like this; dark and deep colors with low light where there was no detail, even at lower isos where usually you get good results. None of these are great shots, but there is lots of detail.

The dog shot is handheld at 1/20 10000 iso with FA100 lens. No detail loss there.

A couple more. Iso 10000 and iso 12800. No noise reduction in post processing.
