For Auto ISO, what is your maximum setting?

The K-50 is reviewed as having good high ISO performance so I set my Auto ISO to 800.

Am I being too reserved and should I set it higher? Or did I pick a good value?

Anyone here have any experiences or opinions on it?

I choose something between 400 and 3200 based on situation.
If it's day time(sunny, cloudy, overcast, ...) and my lens is bellow 100mm, I would stick to 400 at max, but If I'm shooting a longer lens or in lower light condition I would boost it to 800 or 1100.
At night time where there's not much light, I put it on 1600 to 3200 based on the focal length and motion of subject.

Update: I have K-30, which is almost the same body as yours in another chase.

I started off with 6400, then dropped it down to 5000. Nowadays, 4000 is my upper limit for everyday shooting stuff.

I have mine set to 6400 with the preference set to SLOW. I only use auto ISO when in TAv mode, though, so I'm not sure what SLOW actually accomplishes. I decrease the shutter speed a bit if I find it's hitting ISOs that are routinely unacceptable. Still, the point of TAv mode is to control depth of field for objects that are moving quickly (hence the need for setting the shutter speed), so there's only so much latitude to be had on decreasing exposure time.

I think a lot is dependent on the lens, and on the subject and how much you may need to crop.

This was shot with a K-50 and DA*300 at f4, 1/320 and ISO 6400. It loses some detail but I don't think I would have got as much with a lower ISO. This one is cropped to about 50% of the original size. If I could catch this mink with a little more sunshine I would probably not keep these photos, but since this is such an elusive animal I'll keep it, definitely not something you could make a big print of, ... but for the web it's OK.

This was shot with the K-50 and 18-135 at 100mm, at 5.6, 1/125, and ISO 3200, the cat is looking into an overhead light, it is uncropped. I think in this case distance has a little to do with the result, I was pretty close.

I have mine set at a maximum of 1600. It seems to work fairly well for low light.

I've noticed (on my K30) that IQ suffers noticeably at 3200, so I try to cap it at 1600. Having said that, getting a noisy shot is better than not getting the shot at all, in my opinion, and I'll crank it to the max if I have to!

Limiting yourself to ISO 800 is okay if you can use a tripod and slow shutter speed in dim light, but don't be afraid to go higher when needed. A noisy image is better than a blurry image when your subject is moving fast enough to blur images at ISO 800.

Some situations require higher ISOs when it's not practical to use flash or a tripod. Some ways to deal with noise are B&W conversion, or use noise reduction software.

If you like shooting at max ISO800, do it.
If you like shooting at max ISO12800 do it.
If you like shooting only at base ISO do it.

It's up to you to decide and adjust to the circumstances, that's why the controls are there in first place.

Only use it in TAv mode and set it to 3,200.

800 iso is my default for my K-30 and I rarely if ever go above that. Once in a while 1600 but I prefer not to. I'd rather add more light than go to there if I can. I really dislike anything above that though. I won't go above it if I can help it. Sometimes you just have to but I'd rather not.

It depends on the camera and conditions. Sometimes I need it to go up to 6400 and bounce down when the light improves. The modern cameras, especially the 16MP ones like K-01, K-30, K-5, K-50 have good noise performance, so you can push so high. With older models you might want to limit at 1600, or even 800.
Oh, and it depends on personal preferences as well. Some people seem to be allergic to noise, but most viewers don't even notice it

Definitely. It also makes a difference how and where you view the images. Both of these pictures are taken with the K-30 @ ISO 12,800. The second picture has been edited in Topaz DeNoise with a "moderate" setting.

I was experimenting with manual flash settings, and while I do have almost the same shot at ISO 400, it is much darker overall, and only the piece of printed paper is properly exposed. The cross hatching on the background is not an artifact, it is the texture of the material behind the dart board.

It really depends what I'm shooting and why. Anything below 500 is fine in my book. Between 500 and 1500 I know the photo is somewhat compromised but probably usable for everyday purposes. Above that, I'll quit unless 1.I'm documenting an event or game, 2. the subject matter is really compelling &/or 3) there's nothing I'd rather do.

You are being far to conservative , I suggest you do a search on Google for any of the in depth tests / reviews on these bodies and look at the ISO results there you will see images taken at all the settings and you can use that info to base your decissions on that.
