Well then, that will be why you didn't have trouble focussing in live view.
As I mentioned earlier, it's fine in those conditions - but when the sky is pitch black save for some tiny pin pricks for stars, the LCD auto gain makes it impossible.
Have you given this another go with spot metering enabled? I think you said you did but it's weird you are still experiencing problems.

I had the exact same rear lcd blown out issues as you but, as shown earlier with pictures, this was much improved using my K-30 and spot metering in fully manual mode.

Lol I thought you had said that but wasn't going to hunt back on this cell phone ;-)

You're screwed then mate :-( as it works on mine with 6x digital zoom, spot metering and focus peaking.

Good luck! But I don't necessarily think this is a k-30 specific problem.

The first thing I missed when I moved from my old Olympus e-510 to the Kr was the setting to disable the auto gain of the back LCD, I turned off auto gain and left it off 99% of the time with the e-510. Wish it was available on my K-30.

I have been pleasantly surprised by how good my first attempts at moon shots with a K-30 are using the DA55-300.
Used Live View and spot metering, and had no issues so far.

Spot metering fixed the blown out issue for me and allowed me to use the focus aids on my K-30.


I'd suggest dropping your aperture to say f8 or even lower, and the ISO down also. At the distances we're talking about, you don't need to worry about depth of field issues with lower apertures.

I'd suggest dropping your aperture to say f8 (like your first shot) or even lower really, and keeping the ISO down also. At the distances we're talking about, you don't need to worry about depth of field issues with lower apertures.

when all else fails, squint and focus on that sucker through the viewfinder!
Absolutely! It is, after all, a nicely bright sunlit landscape.

It is because you know how to use spot metering whereas the OP doesn't .... good job!!

After reading all of this, I think I will continue to use my K10D for moon shots, less complicated.

Here's of a photo of my first moon shot with K-50.


Live view, metering, manual mode, ISO settings, blah blah blah... Who cares about those in a moon shot? You have plenty of time before the moon would go away. I have a digital camera and I can take and preview as many photos as I want without spending a dime on flim!

1) Just aim the lens at the moon and take the shot.

2) If it works, go home. You're a master now.

3) If it doesn't work, change some reasonable settings and go back to step 1. Otherwise, go to step 2.

So the moon is green cheese!

Did you use the OVF or Liveview?

I just use the OVF. Focus was done manually (there was no AF on the lens.)

Oh my... I thought that's a warm yellow. I have half color blindness

In the ancient days we used the sunny 16 rule for lunar exposures. The Moon receives essentially that same amount of light that Earth does. It is a pretty close approximation of the old 18% grey card too. Add to that the light coming from the Moon to us passes trough the atmosphere and you get the sunny 16 rule. Works pretty good too. Haven't tried that with my K5/K5-IIs but I don't see why it would not work.

As mentioned above, manual exposures for the win. The great thing about digital photography is the ability to almost instantly check you photos.


Sunny 16 rule worked for me too. In case no one but the poster and I know about it, the sunny 16 rule, a relic of film days, is that for normal sunlit scenes, the shutter speed is the inverse of the ISO rating with an aperture of f/16. Halve the shutter speed for each brighter traditional f/stop detent - f/11, f/8, f/5.6, f/4, f/2.8, f/2. As an example, using ISO 100 and f/8, the shutter speed with be 1/2 x/1/2 (2 f/stops) x 1/100 or 1/400 second. Stop down for bright scenes, such as snow or sand and open up for cloudy scenes. Many times I use manual mode with the aperture and shutter set to sunny 16, making tweaks as the scene seems to call for it.

Alternatively, you could also use "link AE to AF point" whilst using matrix metering if you wanted to be more selective with regards to composition. This function only works with autofocus (obv) and, is slightly trickier to use with zoom enabled in live view mode.

How does one stop the damn LCD for compensating in the dark! ?
I can't focus on the moon manually because the damn LCD in live view thinks I want the overall image BRIGHT as day!!!!

Yes I lock AE, makes no difference.
Yes I'm using all manual settings.
As soon as I change Exposure compensation to darken the image, the LCD ramps up the brightness again!!
This is seriously stupid!
I want the live view LCD to show me the image I am getting from my settings! This worked fine on my K-7 (I no longer have it)
Pentax, you silly fools!!! The definition of LIVE VIEW is that it is LIVE!! It should represent what I have set!! Not brighten the hole LCD.. aaarrrghhh!!!

Please tell me I have missed something?
On my K30 when I set the focus mode to SPOT in MANUAL mode, my LCD in Live mode changes its brightness levels as I change the exposure. Hard to believe Pentax would change that for the K50. Focus on the moon with my 600mm f/8.0 catadioptric was quite easy in Live mode.
