here is a couple of views of a Douglas squirrel.
the first is a k1- fa*300 -----uncropped. --near minimum focal distance.
Hand held --- 1/800 sec at f/5.6 ---- using ISO 12500


this one with a little less camera HP is taken with a K3 using a 60-250 at 250.

How high do you push the ISO on your K1?

I don't have a big problem using high ISO routinely. My mindset is that more photos are ruined by camera movement or bad focus than high ISO
this attached photo was taken at 12,800 with decent lighting at 1/5000 and F/14 using an FA300 f/2.8 lens. --- hand held.

I put the camera in the P mode, --- force the ISO high. When you drive up on a herd of elk as here you want to get out of the car and take some photos quick.
With the camera already set to a high ISO even though it's a pretty long lens you don't worry about motion/dof/focus issues. you don't have time
Likewise getting out the tripod etc. may not get you the best photo.... IT may well be a photo of an empty field. I've also got an FA600 F/4 and I'll do hand held wild life/bird photos with
it as well. After I get a bunch of photos, if my target is still there, I may if I think of it, lower the ISO and take some more

Agreed, though it's been a difficult process for me to admit it. do I have much use for a Pentax-A 400 F2.8 with a 1.4x dedicated extender or an FA-600 f4 lens, when I can get the same photo without 2 tripods
with the D FA 150-450.... by setting the ISO up to 25000 or so.? Similarly---what's the macro ring flash for if you have a good working ISO 25000 etc?

The photo that follows is a K-1 with a fa100mm macro 1/1600 f/13 and ISO12500 now if you compare the bug on the bottom flower to the bug on the middle flower, it's clear the the focus on the middle flower is soft
From the settings I got (using the program mode) and a hard set 12500 ISO I had plenty of 'camera' left to tweek the DOF if I wanted to.

The prarie land in the foreground is widely used by quite a number of cattle feed lot operations. The foot hills are used
for logging and you can see a logged off area in the middle of the photo. And the Mountain--- well what can I say---it's
an active volcano----but not an ongoing one--- just every century or so it does something very bad

European settlers became common in the area in the 1840's and though it had apparently done a bad deed
shortly before then, it was generally treated as a dormant volcano until it blew up with a few weeks notice in 1980 and has
largely been quiet since thing

An image of Mt. St. Helens, some 37 years after the May 18, 1980 eruption which lowered the summit by some 1300 feet and triggered the collapse of the north flank ( on the left side of the mountain). This photo
taken April 16, 2017 (today) from a vantage point just east of the Jackson Highway a few miles north of Toledo, Washington, and perhaps 30 miles west of the mountain.

the K-1's are easier to find than a Pentax-A 400- F.2.8 and cheaper too. I've actually been looking, though for a lighter lens for some of my work (trying to decide between the new DFA* --- to 450 zoom
or the classic FA 400 f/5.6 on which I wouldn't hestitate to use the older dedicated extenders --- the 1.4x-L or 2x-L

With the rising levels of useful ISO, the speed of the glass is less critical. and portability becomes easier.

That's what the camera makers have been doing since they have hit the practical limits on increased pixel counts is making each generation
of sensors do better in low light. The rest of the settings were 1/100 at f/9. If I count right the ISO is 6 stops above Kodacolor 400. The approximate
exposure could have been replicated at 1/25 at f2.8. for exposure with kodacolor 400, but the cost would have been shake issues and depth of field.
The thing that makes this picture to me is the background----you usually find doves in places of really bad backgrounds--- parking lots, lawns etc. but here we have
the utter chaos of the background contrasting with the peaceful bird to make an interesting picture and without the high ISO you just can't get there.

I accomplished this with the K-1 using Pentax-A 400mm f/2.8 and a Pentax 1.4L converter. it was late on a dark cloudy rainy day (today). Used 25600 ISO to close the deal.

Seven months before the successor of the K3II?

I don't really agree with that. I have both a K-3 and a K-1 (oh yes K-2 also. I've liked them all.
I've nursemaided and augmented my full frame glass from the K-2 days as I see it what
the k-1 can never match is the extra range of the half frame camera body.

What's really missing in my option from the entire pentax line for wildlife photography is a power zoom that is quiet and can be remote controlled.

add a power tripod to a K-1 with a power remote zoom so you can rotate and elevate and zoom as well as control all the other camera functions
on your cell phone app within wi-fi range and then you have a real wild life camera......

you can set the camera remotely to observe a wide field, and if something shows up whether a mouse or a moose, you can bring the camera to bear,
adjust the zoom, pick an ISO that makes sense and get your photos.... all from far enough away that you presence isn't disturbing it...

Well one thing is clear--they aren't needed as badly as they used to be--- which is probably why the declining interest.

I went to Alaska last summer with particular intent on taking wildlife photos and didn't even take my FA600 lens.

When you combine the impacts of the half frame camera bodies, good quality TC's, and the high ISOs now available, you can get the functionality of a 1200 f/8
in a package that will fit in your airplane carryon.... the head and tail of this juvenile eagle were cut off on this photo because I had too much horsepower on this photo shoot.

Pentax KP - High ISO Samples
Posted By rvannatta

I quite agree that I'm not likely to us 819k ISO, but I don't use the highest numbers on my present cameras others. What I do see is evidence that it will work and provide nice photos at higher ISO's than existing models.
This is progress. I remember being excited when I learned how to cook TRI-X in the darkroom and get 800 out of it. I've purchased almost every top end Pentax ever made beginning with the Spotomatic---oh did I like
an auto coupled light meter, though the K2 was my all time favorite film model. what I've seen in the digital models is steady improvement in low light abilities with the possible exception of the K10 which I regarded as
really lame in low light situations. I now have a K3 and a K1 as cameras of choice, as I have sort of migrated into bird photography.

What I'm finding is that decent bird photos are becoming progressively easier. Birds, it seems, commonly roost in the shadows which has made photographing them difficult and expensive.
implying that my lens collection has such monster lenses as the A-400 f/2.8 -- one of my all time favorites as well as an FA-600 F/4. These are the 16" guns of the navy. They shoot long and hard
IF you can bring them to bear before the target is long gone.

I'm now using ISO 6400 pretty much as my default setting on the K3 and the K-1. IF this new model enables a few higher f stops it will we more than welcome. It means more and more bird photography can
be hand held with affordaable light weight optics.

IT seems like ther are some days that you just have the wrong lens on the camera. Often a 300 mm is a good bet if you are birding, but then this happens.

this is a full frame shot of an eagle with a 300mm f/4.5 lens on a K-3

You know, there are a couple features still missing that are needed to support full remote control of a camera.... It seems with the built in WI-FI we can adjust every button on the K-1... Haven't tried it, but think that is the case, but what
is missing are two critical things----- the ability to Zoom and pan. Now the panning could be handled by building it in to the Aux-battery pak that can be added to the bottom of the camera bodies...-- simply put a tripod mount that can be
rotated by a worm gear motor. the second is a zoom lens that can be remotely controlled.

My understanding of evolution suggests that nearly every feature of critters either serves or has served some purpose, and when looking as cosmetic appearance
it seems likely that coloring has to do with increasing reproductive opportunity or obtaining food, or avoiding being food.

The camera guy (me) messed this one up big time. I was pursuing this bird in an overgrown parking lot by driving around and shootingout the window with a F*300 4.5 and a 1.4xconverter. This quail
isn't much on flyway away from you but they will run away from you. I circled around and got in front of him, but then I was suddenly too close. I really didn't have time to kick off the converter
when the bird turned and stared at me. I cut the birds feet and tail off, but nailed the head..... IT could be that I should try to salvage this by turning into just a head shot....

AFterall the point of the photo is the 'head shot'..... Note how fearsome this otherwise rather passive bird is when it looks directly at you. --- sort of explains its color scheme that
has no message at all when you look at the usual profile. Anyhow it's the straight in the face look that put this photo here, not my miserable technique.





same photo as above but I carried out my ruminations as aggressive cropping. Can you see the giant black mouth????
